AeroCloud

HackerNoon Reporter: Please tell us briefly about your background. I’m George Richardson, and I’m AeroCloud’s CEO. I am a serial entrepreneur, and pre-AeroCloud, I was involved in several different businesses. I aim to build AeroCloud into one of the few tech unicorns in the North West of England. Before my career as an entrepreneur, I was a professional race car driver and competed in the European Le Mans Series. What's your startup called? And in a sentence or two, what does it do? We’re AeroCloud, and we believe airports deserve better. For too long they’ve not had the focus on their needs and pains from the technology companies in the aviation space. We’re giving them cloud-native software that uses technologies like AI and machine learning, at lower costs than they’ve been used to. What is the origin story? I met my co-founder, our CTO, Ian Forde-Smith, at a coffee shop. We became friends and told each other about our backgrounds. Ian had run/owned and sold an airport software business before that was acquired and had ideas for doing it again but using modern technology. My focus was the commercial side - working out how to package and sell the platform to airports in the most effective way. It was clear that our skills complemented each other, so we started working on the business that would become AeroCloud. We went over to the US to some trade shows and met people from airport operations teams. We worked in a co-creation model to develop the platform - building something that airports needed that addressed their problems. And we’re still working like this - listening to what our customers want. What do you love about your team, and why are you the ones to solve this problem? After our seed funding round, I set our Head of People the challenge of finding special and amazing people. It’s as simple as that. We’re constantly looking for candidates who can add value to our clients. We have a real mix of people who are comfortable speaking up and contributing to help our customers be successful. We’re up to 17 now, and continuing to grow! If you weren’t building your startup, what would you be doing? Starting another one! I love the buzz of business and challenging an existing industry with an approach more focussed on customers. I love building teams and solving problems. At the moment, how do you measure success? What are your core metrics? It’s all about ARR and ARR growth - if we’re building a platform that airports want and good relationships with our customers, then they’ll pay for it and keep renewing. What’s most exciting about your traction to date? We’re forming partnerships with airports; they’re not just customers to us. We regularly hear from them about how our platform is making their lives easier and solving their problems. They tell us they really like working with our team too, which is fantastic! Most of our early growth has been through word of mouth - which shows the buzz we’re creating. What technologies are you currently most excited about, and most worried about? And why? We’ve already got AI and machine learning in our platform. We’re excited about other use cases for them in the airport space - that’s what our technology team is working hard on at the moment. The potential for drones and new vehicle technologies like AVTOL is exciting, too - there are both threats and big opportunities for airports in these developments. What drew you to get published on HackerNoon? What do you like most about our platform? Hackernoon is a great place to get interesting, relevant developer news. As a technology company, it’s a great resource for us. What advice would you give to the 21-year-old version of yourself? Enjoy the racing career as much as possible and learn as much about the commercial side as you can. Be prepared for an equally exciting career once it’s over and you’re too old, and your back is shot, and you’re fed up of flying around the world so much! What is something surprising you've learned this year that your contemporaries would benefit from knowing? We’ve been successful despite the pandemic. Airports have been looking for better technology - and especially for anything that can reduce their costs. In the early days of coronavirus, we gave away a free stand planning tool to help airports that suddenly needed to park aircraft for long periods. There are always opportunities, even when it looks like everything is slowing down and the economy is taking a hit. LINK to City Award Page with your company listed. Startup of the Year

As such, a supplier, with approved invoices, can receive the full amount owed by sourcing for funds from financial institutions. In turn, the financiers can provide extensions on the payables depending on the credit-worthiness of the buyer in question. 15.

How a Changing World Turned an Agency Leader into an Executive Coach It’s an understatement to say that the world is facing never-before-seen problems.

Interview With Bryan Seiler on Greedy Banks, turning $150 Into Millions and More Every crypto practitioner has a unique narrative that has brought him or her face-to-face with the realities of the true innovative power of crypto technology. Perhaps, this notion is the reason why the crypto community has stood by the viability of cryptocurrency all through its trying times. As such, the crypto space has evolved into a network of mavericks who are not only tech-savvy but have learned to appreciate and nurture the business side of the crypto economy. 35. "I Believe That Crypto Will Eventually Replace Current Monetary Infrastructures" - Yuri Nesterov During the chaos caused by the global pandemic, P2P, or peer-to-peer, transformed into a growing worldwide movement can no longer be left in shadow. Some experts even regard it as a way to save the global economy from an all-embracive post-pandemic crash. P2P already proved to be advantageous against a traditional exchange model in a number of ways – not least because it allows higher inclusion and can freely function even in countries that do not define cryptocurrency under their jurisdictions. Take an example of India – it is about to embark on the biggest bull rally of all time, and P2P exchanges are the engine behind it. Besides, P2P may be a lifeline for SMEs hit by the economic crash most severely – in conditions where they do not qualify for the bank credit support, P2P may become the only way to bail out. 36. "If Bitcoin Becomes Compliant Tomorrow, All Reservations Against It Will Disappear" - Max Krupyshev With cryptocurrency reaching a fever peak as to even get accepted for tax payments, Bitcoin and other digital currencies gain traction in both public and private spheres. 37.

"The Present Financial System Will be Replaced by DeFi" - Umar Farooq With DeFi trend steadily gaining momentum across the world, 2020 has been deservedly proclaimed as the year of “DeFi Renaissance”. Indeed, no other technological innovation shook up the world to the same extent as decentralized financial technology did earlier this year. Even in the face of such a major ground-shaking event as Covid-19, not only DeFi stood up to its position, but also magnified in value to an extent hardly envisaged half a year ago. The TVL index accurately reflects it – compared to the start of this year with $80 million, the total value has now augmented to the transcendental value of $11 billion. 40. Lessons I Learnt From Becoming a CEO As someone who’s been the CEO for years, I think I might be of some help here. Over these years, I saw hundreds of things not working out the way I initially planned but, knowing that I was in the middle of a process kept me going. 41. Why My New Book is a Failed Attempt at Something I Can’t Put My Finger On On June 30th, 2020 my new book, The Humility Imperative — Effective Leadership in an Era of Arrogance — will be released. 42. How is Finance and Investment Changing? — An Interview with the CEO of Antares Due to several factors, the financial and investment landscape is currently undergoing a significant shift. Chief among them is the economic crisis resulting from the COVID-19 pandemic that subsequently forced nations to lock down their economies. 43. "Centralized service providers theoretically can end their products" - Masato Kakamu The sheer number of professionals and artisans opting for more flexible working and sharing models aided by significant advancements in communication and transaction-based technologies have surged in recent years. 44. Interview with Steven Parker, Former General Manager of Visa Despite the Covid-19 pandemic unsettling different faces of our lives, this year has been fantastic for cryptocurrencies. It could be argued most institutions finally embraced Bitcoin and other cryptocurrencies, given the number of institutional investors that got into the market. Also, people got to see first-hand why cryptocurrencies could be key for survival, especially when human contact and the use of paper notes were prohibited. 45. "Decentralized Protocols Disintermediate Misaligned Agencies" - Melanie Mohr [Interview] The Decentralized economy based on permissionless protocols is swiftly growing as more people in the world embrace the idea of P2P ecosystems. 46.  "IEO Will Continue to be Mainstream Even With IDO And DeFi on The Rise" - Kiana Shek The current push for DeFi has not only changed the way we engage with our everyday financial needs but has also introduced new means of accessing, supporting, and investing in new projects. Tagged as Initial DEX Offerings (IDO), the possibility of bypassing restrictions when identifying and investing in projects has improved crypto funding. However, this does not mean that other models of crowdfunding have become redundant. For what is worth, Initial Exchange Offering (IEO) is still the go-to option for projects that prefer to capitalize on established launchpads and introduce a more diverse array of crypto products not necessarily restricted to the financial sector. 47. Empowering Creators with Tealfeed Co-founder Sourabh Kaushik In this slogging AMA, we were joined by Tealfeed Cofounder Sourabh Kaushik, we discuss everything Tealfeed, including future ambitions for the platform. 48. You Owe Your Team Prompt Layoffs and a New Plan Right now, the start-up community is facing upheaval. Although shelter-in-place rules tend to affect some companies more than others and hopefully will be limited to the short-term, all of us will be in uncharted territory for the rest of the year, as we navigate chaotic capital markets and a possible recession. 49. "All DeFi Applications Are Shooting For The Sky But no One is Wearing a Parachute" - Allan Henders There is a lot to take away from the price performance of the digital asset market in 2020. One of such is that the concept of bitcoin halving, as expected, is a major contributing factor to the success of the bitcoin market and has eventually delivered the level of price swings projected during the pre-halving days. Another is that DeFi is perhaps the most potent application of cryptocurrency technology, which makes it the most plausible instigator of the next wave of growth. In the months following the global market crash, the DeFi landscape has attracted around $14 billion worth of capital. Why is this so? 50. "The Idea Behind Digital Сurrencies is to Reduce Total Control Over Money Markets" - Dmitry Filyaev The crypto market has evolved significantly since Bitcoin’s whitepaper was conceived 12 years ago, shortly after the U.S Financial Crisis which devastated the global economy. Today, this space enjoys a cool $400 billion in market capitalization with Bitcoin taking the lion share at a 62.4% dominance. Unlike like in the past where Bitcoin was the main narrative, dynamics are now shifting as crypto innovators pivot towards decentralized products and ecosystems. 51. "Traditional industries will die under their own pressure." - Byung-Hung Lee, CEO of LCMS COIN "Traditional industries will die under their own pressure. This day is not long to come." 52. "DeFi Space Welcomes Anyone, From Anywhere" - Victor Larionov Entering the decentralized finance space can often seem daunting. With the help of companies such as Priority Token, that process becomes a lot smoother. Existing technology companies can reach out to a growing network of highly qualified investors. 53. "Blockchain Technologies Provide a Solution For Almost Every industry" -  Charles Allen There are several narratives identified as the propelling factors for the increasing demand for crypto assets. However, the most potent is the “store of value” narrative that has established crypto, most especially bitcoin, as the go-to-asset for investors looking to hedge against inflation. This sentiment trails what experts term as a critical period in human history borne by an unrelenting health crisis and a myriad of flawed economic policies designed to suppress its impact. According to a report by the Economic Policy Institute, over 17 million Americans will permanently lose their jobs because of the coronavirus pandemic. 54.

As companies continue to migrate their workloads from on-premise solutions to public Cloud Service Providers (CSPs) like AWS, it becomes increasingly difficult to understand the complete picture of what might be running within an organization’s cloud. Even simple applications commonly have multiple environments such as Development, Staging, and Production. For more complex workloads, there are additional environments, microservices, queues, notification services (e.g. SNS, SES), data stores, and more. Even when all this resides under a single AWS account, it is hard to conceptualize let alone manage sprawling cloud resources. Take two seemingly simple questions: “How many EC2 instances am I currently running across all my AWS accounts?” and, “Have I correctly tagged all of my production environment EC2 instances with ?”. These are very difficult to answer using the AWS console or CLI. environment: production This difficulty is compounded by common best practices such as spreading resources across regions and separating workloads across several accounts within an AWS Organization. Performing an inventory using the AWS console requires keeping a manual count while changing regions and accounts to ensure you didn’t miss anything. Unfortunately, using the AWS CLI is not much easier. For each region and account you wish to query, you need to multiple commands, calling the correct APIs for each asset type (i.e. ). Then you must manually aggregate the results and double-check you’re not missing any data. aws ec2 describe-instances Rather than give yourself a migraine dealing with all of this cross-region, cross-account manual data fetching – let’s see what this would look like using . CloudGraph is the free and open-source GraphQL API for AWS that vastly simplifies the process of answering asset inventory, compliance, and billing questions. CloudGraph So how do you get started? First, you using the single install command: install CloudGraph npm install npm install -g @cloudgraph/cli Next, you scan of your AWS accounts at once by configuring CloudGraph using the credentials you already have stored in your local ~/.aws/credentials file (see the if you’d like more information on that). You can also scan accounts using IAM roles if you prefer. Initialize CloudGraph for our AWS accounts by running the following command: all CloudGraph AWS provider README cg init aws If you have a local AWS credentials file, you should see a list of profiles to select. In my case, I will choose the profiles and so I can scan the AWS accounts running my Development and Production environments. default master Next, you can pick the regions you want CloudGraph to scan. In my case this is , , and . If you’re unsure what regions you have resources in, you can always select them all. CloudGraph will automatically scan . If necessary, this can be modified by passing the flag to the init command (see the for more information on passing flags). us-east-1 us-east-2 us-west-1 all supported resources -r CloudGraph README Now you are ready to scan your AWS accounts! Run the following command to launch a local instance of , the graph database that CloudGraph uses to locally store your data. Dgraph cg launch And finally, run the following command to scan all of your configured AWS accounts, regions, and services: cg scan aws Feel free to grab a quick cup of coffee while this runs. After the scan is complete, CloudGraph will open the you selected in the step. You can use this query tool to ask pretty much any question about your AWS resources. GraphQL query tool cg init Let’s answer the first question I posed at the start of this post: “How many EC2 instances are currently running across all my AWS accounts?”. This is simple to answer with CloudGraph. As you can see, I have 46 EC2 instances running across the two environments I chose to scan. Note that CloudGraph also provides the total of all scanned resources in the report printed at the end of each scan. Maybe I want to take this a step further and view metadata about these EC2 instances such as their . I can easily run a GraphQL query against my EC2 instances and request only the specific metadata I care about. instanceType Now let's answer the second question I posed: “Have I correctly tagged all of my production environment EC2 instances with ?”. I could actually do this in a couple of different ways. environment: production First, I could directly query the EC2 instances in Production and see their tags, like so: query {
  queryawsEc2(filter: {accountId: {eq: "632*****77"}}) {
      id
      tags {
        key
        value
      }
  }
} This output clearly shows me all my EC2 instances in account “632…” and their tags. A second and more direct way of asking this question would be to use and filter on the key and value I would like to target: queryawsTag query {
  queryawsTag(filter: {key: {eq: "environment"} and: {value: {eq: "production"}}}) {
    ec2Instance(filter: {accountId: {eq: "632*****77"}}) {
      id
      arn
    }
  }
} Now I’m only getting back EC2 instances that are tagged with “environment: production”. This would also work for other taggable AWS resources such as VPCs, IAM users, S3 buckets, or EKS clusters. CloudGraph makes it easy to inventory your assets no matter how many different regions or accounts they reside in. The sky's the limit for what you can query!

A Complete Inventory of Your AWS Footprint in 5 Minutes

Yesterday Apple kicked off its annual World Wide Developer’s Conference (WWDC), and the keynote held some big surprises for its ARKit platform. Among other improvements, ARKit 2 will hold the following new functionality: 3D object detection Persistent experiences Shared experiences Now, we’ve all been hearing about the ARCloud lately, with companies like Google pushing their services at this year’s Google I/O, as well as smaller startups like 6D.ai, and Placenote trying to wedge themselves into the space as the authoritative platform. Apple, in the last few years, has been working silently (normal modus operandi) to first create a framework for detecting surfaces, and now, for detecting objects, serializing, and sharing the recognized world. Let’s take a closer look at each of these new features. Detecting Objects As Lego demonstrated in the keynote, ARKit is now able to detect physical objects. The way that this is done is by initially training the model (as in machine learning model, not 3D model) presumably using the Vision and Machine Learning facilities that Apple has developed under the hood. The object that is to be detected is first analyzed by pointing your phone camera at it, and moving all around the areas that are to be recognized. This allows the framework to analyze and save the feature points that it finds on your object. The framework is then able to recognize the same feature points in a different session by comparing the two datasets. Interacting in the same world To train the machine learning model, Apple is providing the source code to a full-featured app that they wrote to simplify the process of scanning the object. From there, the process is simple. Load the model into your app, start an object detection session and when the object is detected, you’re given the proper transforms for laying out your world around the object. Virtual content overlaid on top of real object Persistent Experiences Along with the new detection capabilities, the major feature is the ability to persist the recognized world. That is, once you detect enough feature points in the area that you’re scanning, you’re able to save the data that describes the world. You can then reload the world, not just in the same device, but any other device as well, allowing for a quick startup when looking at the same area at a later time. Save a world map when your app becomes inactive, then restore it the next time your app launches in the same physical environment. -Apple ARKit docs This is a really important feature. This allows for serializing the current scene, feature points and anchors in all, making restarting a session nearly instantaneous. This is also used with the shared experience functionality, whereby the same world can be scanned once and used by multiple users, as described in the next section. Shared Experiences I’m currently writing this while watching a match between two conference-goers in a game that Apple created to showcase multiuser AR. SwiftShot is a take on a tower battle, where each player has to knock down the other’s towers using AR slingshots that they are controlling with iPads. The players are on each side of a large wooden table, which is holding the virtual content. The match is simulcast via a third iPad that a staff member is holding, acting as the camera person. There is a large television showing the match, which includes the players and the virtual content. The play area is rock solid on the table, showing the advanced tracking capabilities of ARKit. Craig Federighi on shared AR experiences This is a great example of a virtual world being shared by multiple participants. They are both seeing the same world, watching their actions affect the scene objects in realtime. This opens up amazing new possibilities for games and experiences, including being able to collaborate and work on the same subject together. With two devices tracking the same world map, you can build a networked experience where both users can see and interact with the same virtual content. -Apple ARKit docs What all this means Apple came out of nowhere with ARKit, and they are quickly iterating on the framework, even going as far as updating to ARKit 1.5 during an iOS point release, which included static image and vertical plane detection. “Simply put, we believe augmented reality is going to change the way we use technology forever,” — Apple CEO, Tim Cook With ARKit 2.0 they raising the bar and moving quicker than some startups, releasing technology that may render many of them obsolete even before they launch. This train seems unstoppable, with Apple making cohesive frameworks that open up new possibilities for developers to create amazing experiences. is a developer who’s worked on more platforms and languages than he cares to admit to. He believes in building products that create memorable user experiences. To Dan, the users are first, the platforms are second. Follow Dan on or to hear more from him.

The Apple AR Train

In this blog post, I will show you how to create a video call app using ZEGOCLOUD and React. For context, ZEGOCLOUD is a cloud-based that provides developers with a set of APIs and SDKs to easily build video calling applications. video call platform Prerequisites Before you start, you will need to: and project. Create a ZEGOCLOUD account Have a basic understanding of React. Creating a ZEGOLCOUD account and project Step 1: Head over to the website and create an account. ZEGOCLOUD Step 2: Now, create a new project and grab the appId and serversecret from the project dashboard. Creating a Video Call App The following steps show you how to create a video call app using ZEGOCLOUD and React: Create a new React project. Install the ZEGOCLOUD React SDK. Import the ZEGOCLOUD SDK into your project. Join a room. Create a local audio and video stream. Start a video call. Render the video streams. Step 1: Create a new React project You can create a new React project using the following command: npx create-react-app video-call-app This will create a new directory called video-call-app with a basic React project. Step 2: Install the ZEGOCLOUD React SDK You can install the ZEGOCLOUD React SDK using the following command: npm i zego-express-engine-webrtc This will install the ZEGOCLOUD React SDK into your project. Step 3: Import the ZEGOCLOUD SDK into your project and initialize it In your project's index.js file, import the ZEGOCLOUD SDK and initialize the zegocloud app by the function as follows: import React from "react";
import { ZegoExpressEngine } from "zego-express-engine-webrtc";

function App() {
  useEffect(() => {
    const zg = new ZegoExpressEngine(
      process.env.NEXT_PUBLIC_ZEGO_APP_ID,
      process.env.NEXT_PUBLIC_ZEGO_SERVER_ID
    );
  }, []);
  return (
    <div>
      <div id="local-video"></div>
      <div id="remote-video"></div>
    </div>
  );
}

export default App; In the above step, we have utilized the useEffect hook to initialize the ZegoClouds library by passing the app ID and server secret as parameters. Step 4: Join a Room import React from "react";
import { ZegoExpressEngine } from "zego-express-engine-webrtc";

function App() {
  useEffect(() => {
    const initializeApp = async () => {
      const zg = new ZegoExpressEngine(
        process.env.NEXT_PUBLIC_ZEGO_APP_ID,
        process.env.NEXT_PUBLIC_ZEGO_SERVER_ID
      );
      await zg.loginRoom(
        "zego-room",
        token,
        { userID: "123", userName: "kishan" },
        { userUpdate: true }
      );
  }, []);
  return (
    <div>
      <div id="local-video"></div>
      <div id="remote-video"></div>
    </div>
  );
} Now in this step, we have joined the passing of the token, userId, and userName, and the userUpdate status. Step 5: Create a local audio and video stream. import React from "react";
import { ZegoExpressEngine } from "zego-express-engine-webrtc";

function App() {
  useEffect(() => {
    const initializeApp = async () => {
      const zg = new ZegoExpressEngine(
        process.env.NEXT_PUBLIC_ZEGO_APP_ID,
        process.env.NEXT_PUBLIC_ZEGO_SERVER_ID
      );
      await zg.loginRoom(
        "zego-room",
        token,
        { userID: "123", userName: "kishan" },
        { userUpdate: true }
      );

      const localStream = await zg.createStream({
        camera: {
          audio: true,
          video: true,
        },
      });
      // Get the audio tag.
      const localAudio = document.getElementById("local-video");

      const videoElement = document.createElement("video");
      videoElement.id = "local-video";
      videoElement.className = "h-28 w-32";
      videoElement.autoplay = true;
      videoElement.muted = false;

      videoElement.playsInline = true;

      localAudio.appendChild(videoElement);

      const td = document.getElementById("audio-local");
      td.srcObject = localStream;
    };
  }, []);
  return (
    <div>
      <div id="local-video"></div>
      <div id="remote-video"></div>
    </div>
  );
} We have created the video elements here where we will be actually displaying the video streams of our local webcam. Step 6: Start a video call. import React from "react";
import { ZegoExpressEngine } from "zego-express-engine-webrtc";

function App() {
  useEffect(() => {
    const initializeApp = async () => {
      const zg = new ZegoExpressEngine(
        process.env.NEXT_PUBLIC_ZEGO_APP_ID,
        process.env.NEXT_PUBLIC_ZEGO_SERVER_ID
      );
      await zg.loginRoom(
        "zego-room",
        token,
        { userID: "123", userName: "kishan" },
        { userUpdate: true }
      );

      const localStream = await zg.createStream({
        camera: {
          audio: true,
          video: true,
        },
      });
      // Get the audio tag.
      const localAudio = document.getElementById("local-video");

      const videoElement = document.createElement("video");
      videoElement.id = "local-video";
      videoElement.className = "h-28 w-32";
      videoElement.autoplay = true;
      videoElement.muted = false;

      videoElement.playsInline = true;

      localAudio.appendChild(videoElement);

      const td = document.getElementById("audio-local");
      td.srcObject = localStream;
    };

    const streamID = "123" + Date.now();

    zg.startPublishingStream(streamID, localStream);
  }, []);
  return (
    <div>
      <div id="local-video"></div>
      <div id="remote-video"></div>
    </div>
  );
} Here we have started publishing our local stream to the specified room. Step 7: Render the video streams. import React from "react";
import { ZegoExpressEngine } from "zego-express-engine-webrtc";

function App() {
  useEffect(() => {
    const initializeApp = async () => {
      const zg = new ZegoExpressEngine(
        process.env.NEXT_PUBLIC_ZEGO_APP_ID,
        process.env.NEXT_PUBLIC_ZEGO_SERVER_ID
      );

      zg.on(
        "roomStreamUpdate",
        async (roomID, updateType, streamList, extendedData) => {
          if (updateType == "ADD") {
            const rmVideo = document.getElementById("remote-video");
            const vd = document.createElement("video");
            vd.id = streamList[0].streamID;
            vd.autoplay = true;
            vd.playsInline = true;
            vd.muted = false;
            if (rmVideo) {
              rmVideo.appendChild(vd);
            }
            zg.startPlayingStream(streamList[0].streamID, {
              audio: true,
              video: true,
            }).then((stream) => {
              vd.srcObject = stream;
            });

            // New stream added, start playing the stream.
          } else if (updateType == "DELETE" && zg && streamList[0].streamID) {
            zg.stopPublishingStream(streamList[0].streamID);
            zg.logoutRoom("123");
          }
        }
      );

      await zg.loginRoom(
        "zego-room",
        token,
        { userID: "123", userName: "kishan" },
        { userUpdate: true }
      );

      const localStream = await zg.createStream({
        camera: {
          audio: true,
          video: true,
        },
      });
      // Get the audio tag.
      const localAudio = document.getElementById("local-video");

      const videoElement = document.createElement("video");
      videoElement.id = "local-video";
      videoElement.className = "h-28 w-32";
      videoElement.autoplay = true;
      videoElement.muted = false;

      videoElement.playsInline = true;

      localAudio.appendChild(videoElement);

      const td = document.getElementById("audio-local");
      td.srcObject = localStream;
    };

    const streamID = "123" + Date.now();

    zg.startPublishingStream(streamID, localStream);
  }, []);
  return (
    <div>
      <div id="local-video"></div>
      <div id="remote-video"></div>
    </div>
  );
} Now as soon as the other user joins the room, we want to display the upcoming video stream and render it to the DOM.

How to Build a Video Call App with ZEGOCLOUD and React

What is video API Video API is an interface dedicated to providing audio and video transmission services, mainly divided into two types: and . static video API live video API Static Video API Static Video API is an API that provides video file play services. Service providers offer video file cloud storage and distribution services and provide video services through protocol interfaces such as HTTP and . CDN RTMP For example, YouTube and Instagram use Static Video API. Live Video API For example, , Yalla, and Uplive use the Live Video API. Live.me The static video API is easy to understand and pulls video files from the cloud through the streaming protocol. The live video API is more complicated. How does it ensure the video can be transmitted to the other end quickly, smoothly, and clearly? In this article, we will introduce the logic behind the live video API in detail. What Can The Video API Do The live video API application is becoming more extensive with the continuous improvement of network bandwidth and device performance. It makes many scenarios possible, such as: Live Online education Video conferencing Telemedicine Video calls Multiplayer What Happens After The Video API For the live video API, it is necessary to ensure that the video data can complete the end-to-end transmission within 500ms and, simultaneously, guarantee the clarity of the video picture and the flow of the call. Therefore, the live video API needs to ensure that the audio and video data can realize end-to-end data transmission in a fast, large and stable manner. A complex system is required to ensure the availability of the live video API. As shown in the figure, the live video API mainly layered the functions of 6 modules: 1. Audio and video capture Audio and video capture is the source of audio and video data collected via cameras, microphones, screens, video files, recording files, and other channels. It involves using color spaces, such as and and extracting audio features, such as sampling rate, number of channels, bit rate, audio frame, etc. RGB YUV 2. Audio and video preprocessing The audio and video preprocessing are mainly for business scenarios, and the collected data is processed once and again to optimize the customer experience. For example: Video data processing for beauty, filters, special effects, etc. Audio data processing includes voice change, reverberation, echo cancellation, noise suppression, volume gain, etc. 3. Audio and video encoding Audio and video coding ensures that audio and video data can be transmitted quickly and safely on the network. Commonly used encoding formats are Video encoding format: , Audio coding format: OPUS, AAC. H264 H265 4. Audio and video transmission Audio and video transmission is the most complex module in the video API. To ensure that the audio and video data can be transmitted to the opposite end quickly, stably, and with high quality in a complex network environment, streaming protocols such as RTP, HTTP-FLV, HLS, and RTMP can be used. Various anomalies such as data redundancy, loss, out-of-order, flow control, adaptive frame rate, resolution, jitter buffering, etc., must be resolved using multiple algorithms. So whether video API is worth choosing, we need to focus on whether the manufacturer has outstanding audio and video transmission advantages. 5. Audio and video decoding Audio and video decoding means that after the audio and video data is transmitted to the receiving end, the receiving end needs to decode the data according to the received data encoding format. There are two video decoding methods, hardware decoding, and software decoding. Software decoding generally uses the open source library FFMpeg. Audio decoding only supports software decoding; use FDK_AAC or OPUS decoding according to the audio encoding format. 6. Audio and video rendering Audio and video rendering is the last step in the video API processing process. This step seems to be very simple. You only need to call the system interface to render the data to the screen. However, one must process much logic to align the video picture with the audio. Still, now there is a standard processing method to ensure the synchronization of the audio and video. How to use ZEGOCLOUD video API Building a complete set of real-time audio and video systems is complex work. Nevertheless, many Video APIs help us solve the underlying complex operations. We only need to focus on the upper-level business logic. The following will introduce how to use the to implement the video calling function. ZEGOCLOUD Video API 1. Implementation process The following diagram shows the basic process of User A playing a stream published by User B: The following sections explain each step of this process in more detail. 2. Optional: Create the UI Before creating a instance, we recommend you add the following UI elements to implement basic real-time audio and video features: ZegoExpressEngine A view of the local preview A view for remote video An button End 3. Create a ZegoExpressEngine instance To create a singleton instance of the class, call the method with the of your project. ZegoExpressEngine createEngine AppID /** Define a ZegoExpressEngine object */
ZegoExpressEngine engine;

ZegoEngineProfile profile = new ZegoEngineProfile();
/** AppID format: 123456789L */
profile.appID = appID;
/** General scenario */
profile.scenario = ZegoScenario.GENERAL;
/** Set application object of App */
profile.application = getApplication();
/** Create a ZegoExpressEngine instance */
engine = ZegoExpressEngine.createEngine(profile, null); 4. Log in to a room To log in to a room, call the method. loginRoom /** create a user */
ZegoUser user = new ZegoUser("user1");


ZegoRoomConfig roomConfig = new ZegoRoomConfig();
/** Token is generated by the user's own server. For an easier and convenient debugging, you can get a temporary token from the ZEGOCLOUD Admin Console */
roomConfig.token = "xxxx";
/** onRoomUserUpdate callback can be received only by passing in a ZegoRoomConfig whose "isUserStatusNotify" parameter value is "true".*/
roomConfig.isUserStatusNotify = true;

/** log in to a room */
engine.loginRoom("room1", user, roomConfig, (int error, JSONObject extendedData)->{
    // (Optional callback) The result of logging in to the room. If you only pay attention to the login result, you can use this callback.
}); Then, to listen for and handle various events that may happen after logging in to a room, you can implement the corresponding event callback methods of the event handler as needed. engine.setEventHandler(new IZegoEventHandler() {

    /** Common event callbacks related to room users and streams. */

    /** Callback for updates on the current user's room connection status. */
    @Override
    public void onRoomStateUpdate(String roomID, ZegoRoomState state, int errorCode, JSONObject extendedData) {
        /** Implement the callback handling logic as needed. */
    }

    /** Callback for updates on the status of other users in the room. */
    @Override
    public void onRoomUserUpdate(String roomID, ZegoUpdateType updateType, ArrayList<ZegoUser> userList) {
        /** Implement the callback handling logic as needed. */
    }

    /** Callback for updates on the status of the streams in the room. */
    @Override
    public void onRoomStreamUpdate(String roomID, ZegoUpdateType updateType, ArrayList<ZegoStream> streamList, JSONObject extendedData){
        /** Implement the callback handling logic as needed. */
     }

}); 5. Start the local video preview To start the local video preview,  call the method with the view for rendering the local video passed to the parameter. startPreview canvas You can use a , , or to render the video. SurfaceView TextureView SurfaceTexture /**
 *  Set up a view for the local video preview and start the preview with SDK's default view mode (AspectFill).
 *  The following play_view is a SurfaceView, TextureView, or SurfaceTexture object on the UI.
 */
engine.startPreview(new ZegoCanvas(preview_view)); 6. Publish streams To start publishing a local audio or video stream to remote users, call the method with the corresponding Stream ID passed to the parameter. startPublishingStream streamID /** Start publishing a stream */
engine.startPublishingStream("stream1"); Then, to listen for and handle various events that may happen after stream publishing starts, you can implement the corresponding event callback methods of the event handler as needed. engine.setEventHandler(new IZegoEventHandler() {
    /** Common event callbacks related to stream publishing. */

    /** Callback for updates on stream publishing status.   */
    @Override
    public void onPublisherStateUpdate(String streamID, ZegoPublisherState state, int errorCode, JSONObject extendedData){
        /** Implement the callback handling logic as needed. */
    }
}); 7. Play streams To start playing remote audio or video stream, call the method with the corresponding Stream ID passed to the parameter and the view for rendering the video passed to the parameter. startPlayingStream streamID canvas You can use a , , or to render the video.
