Electron BrowserWindow API has some platform-specific APIs:
https://www.electronjs.org/docs/api/browser-window

For example, setWindowButtonVisibility is only available on macOS. We shouldn't call this API in Windows.

After deploying the app using Cloud9, the app crashes with the following error:

Hi there :

The deployment failed when uploading the lms.zip to s3 bucket. It mentioned "release/lms.zip does not exist.
Please kindly advise. Thanks a lot !

... uploading Mac installer (this may take a while) ...
--> aws s3 cp --acl public-read release/lms.zip s3://chime-211259373114-releases/mac/lms.zip

Command aws failed with exit code 255 signal null

The user-provided path release/lms.zip does not exist.

Can it be deployed and run on a VPS? Say, on a digitalocean or linode server.

If yes, how? Which example should I use and where is it described at all?

Extending to
#27

Is there any way that we can test the MAS build before uploading to App Store?

When I try to deploy this app from my local machines its give me the error:
"Command aws failed with ENOENT"

I have aws cli and my keys configured on this mac and regularly deploy AWS lambda functions from it.

Hey Guys,

I am facing an issue while running the ### react-select### module (https://www.npmjs.com/package/react-select) in the production build, which works absolutely well in the development run.

Getting the following error:

Do I have to do some settings for the prod build?

Same issue as #84
I am experiencing the same problem. The error is saying the mac zip file didn't get created, and I don't see the mac zip file in the release directory. So I postulate the problem is the mac zip file is not being created. Yet, I don't see an error either. This is on Cloud9. You might want to reopen this, because I think something is wonky with the deploy script.

... uploading Mac installer (this may take a while) ...
--> aws s3 cp --acl public-read release/human0.zip s3://human0-releases/mac/human0.zip

Hi team,

We are trying to use Chime SDK to create meetings in our application. Using a Lambda Serverless Nodejs API we expose 3 endpoints, create-meeting, create-attendee, end-meeting, we deployed the service in AWS us-east-1 and able to invoke the methods, see below the server-side implementation.

Create meeting:

    const chime = new Chime({ region: 'us-east-1' })
    chime.endpoint = new Endpoint('https://service.chime.aws.amazon.com/console')

    const request = {
        // Use a UUID for the client request token to ensure that any request retries
        // do not create multiple meetings.
        ClientRequestToken: uuidv4(),

        // Specify the media region (where the meeting is hosted).
        MediaRegion: 'us-east-1'
    }

    const meeting = await chime.createMeeting(request).promise()

    // Return the meeting and attendee responses. The client will use these
    // to join the meeting.
    return res.status(201).json({
        JoinInfo: meeting
    })

Create attendee:

    const chime = new Chime({ region: 'us-east-1' })
    chime.endpoint = new Endpoint('https://service.chime.aws.amazon.com/console')

    // Create new attendee for the meeting
    console.info('Adding new attendee')
    const attendee = await chime.createAttendee({
        // The meeting ID of the created meeting to add the attendee to
        MeetingId: req.body.meetingId,

        // Any user ID you wish to associate with the attendeee.
        // For simplicity here, we use a random UUID for uniqueness
        // combined with the name the user provided, which can later
        // be used to help build the roster.
        ExternalUserId: uuidv4()
    }).promise()

    return res.status(201).json({
        JoinInfo: attendee
    })

Everything works fine for the sake of example we have the below responses.

const meetingResponse = {
      JoinInfo: {
        Meeting: {
          MeetingId: "1de5b127-cfd6-44e9-ab21-e1760d7f9152",

        },
      },
    }

In a ReactJS front end client we wire up the meeting session configuration and trying to start audio-video.

import {
  ConsoleLogger,
  DefaultDeviceController,
  DefaultMeetingSession,
  LogLevel,
  MeetingSessionConfiguration,
} from "amazon-chime-sdk-js"

export default class ChimeSdkWrapper {
  createRoom = async (audioElement, videoElement) => {

    const meetingResponse = // from above
    const attendeeResponse = // from above

    const configuration = new MeetingSessionConfiguration(
      meetingResponse.JoinInfo.Meeting,
      attendeeResponse.JoinInfo.Attendee
    )
    await this.initializeMeetingSession(
      configuration,
      audioElement,
      videoElement
    )
  };

  async initializeMeetingSession(configuration, audioElement, videoElement) {
    let logger
    logger = new ConsoleLogger("SDK", LogLevel.INFO)
    const deviceController = new DefaultDeviceController(logger)

    configuration.enableWebAudio = true
    configuration.enableUnifiedPlanForChromiumBasedBrowsers = true

    const meetingSession = new DefaultMeetingSession(
      configuration,
      logger,
      deviceController
    )

    const audioInputDevices = await meetingSession.audioVideo.listAudioInputDevices()
    const audioOutputDevices = await meetingSession.audioVideo.listAudioOutputDevices()
    const videoInputDevices = await meetingSession.audioVideo.listVideoInputDevices()

    audioInputDevices.forEach((mediaDeviceInfo) => {
      console.log(
        `Device ID: ${mediaDeviceInfo.deviceId} Microphone: ${mediaDeviceInfo.label}`
      )
    })

    await meetingSession.audioVideo.chooseAudioInputDevice(
      audioInputDevices[0].deviceId
    )

    await meetingSession.audioVideo.chooseAudioOutputDevice(
      audioOutputDevices[0].deviceId
    )

    await meetingSession.audioVideo.chooseVideoInputDevice(
      videoInputDevices[0].deviceId
    )

    meetingSession.audioVideo.bindAudioElement(audioElement)

    const observer = {

      audioVideoDidStart: () => {
        console.log("Started")
      },

      audioVideoDidStartConnecting: (reconnecting) => {
        console.log(`session connecting. reconnecting: ${reconnecting}`)
      },

      audioVideoDidStop: (sessionStatus) => {
        console.log(`session stopped from ${JSON.stringify(sessionStatus)}`)
      },

      // videoTileDidUpdate is called whenever a new tile is created or tileState changes.
      videoTileDidUpdate: (tileState) => {
        // Ignore a tile without attendee ID and other attendee's tile.
        if (!tileState.boundAttendeeId || !tileState.localTile) {
          console.log("should be ignored")
        }

        meetingSession.audioVideo.bindVideoElement(
          tileState.tileId,
          videoElement
        )
      }

    }

    meetingSession.audioVideo.addObserver(observer)
    meetingSession.audioVideo.startLocalVideoTile()
    meetingSession.audioVideo.start()
  }
}

Trying to keep it as minimal as possible at the moment.

Running the front-end client and invoking the createRoom method will show the dialog to allow mic and camera, initialize camera (led light on) and then throw an error Forbidden 403 with the message

Message: "Profile is not an attendee of the conference <1de5b127-cfd6-44e9-ab21-e1760d7f9152>"

I really don't understand why this might be the case since meeting and attendee successfully created. Is there some kind of authentication/authorization needed on the reactjs application we miss; it looks like that!

On another note, is there some kind of 'console' where we can debug Chime SDK meetings created, get status, etc?
How long a meeting will stay as a resource?

Thank you!

Hi,

Is it possible to run this demo inside a browser? I don't need electron part.

Thanks in advance.

Hello,

Screen sharing is working fine, but it is not working with the following scenario.

1. Select window and start screen share (Working fine)
2. Close(remove) the selected window previously
3. Stop the content share
4. Not able to share screen again (its automatically get resize when start to screen share)

i thinks this the bug, handle window remove event while screen share.

can you please provice the solution.

thanks.

I have successfully deployed the application to the AWS and when I install the /release/app.dmg, it's successfully installed the app in my MacBook.

Also, I can open it and join as teacher or student, but can't turn on the video option.

Hello, I want to make the web site similar UI of desktop app with using the same source code.

How I can do that?

After giving the appropriate permission to execute the app crashes. It seems that is not compatible with this version of MacOS

We are trying to submit the app in the Apple Mac store, but getting rejection with the following error:

Specifically, App still launches to no UI; user is unable to use the app.
Note: No main window appears on launch, menu and icon on Dock only.

Any Idea?

Hello Support Team,

We are using the following classroom application with the customisation at the design level. Overall, application work well, but at the some lever when call is longer, screen sharing stopped and behave randomly.

https://github.com/aws-samples/amazon-chime-sdk-classroom-demo

I think it's memory or cpu usage increasing.

So, Can you please suggest on this?

facing issue with audio with page load ( audio not working fine, some times getting below error and then stop audio working )

is there any solution without upgrading electron version ???

thanks.

Hi Team,

After the completion of step 1(Option 2: Deploy from your local machine), i was trying to run the app locally with yarn dev command. Currently i'm facing couple of issues:

1. Getting below error with yarn dev command:
   

2. Audio/Video not working locally (it works in application under release folder):
   I'm was able to join as a Teacher/Student in app. & web socket seems to be work. Issue is with audio/video, unable to access them locally in app.

Versions:
MacOS - Catalina V10.15.4 (19E287)
node - v11.10.1

Pls. let me know if you need any other info.

Thanks.

Hi guys!

I'm trying to implement your JS SDK API in our project based on Svelte3 and everyhting seems to be fine except the fact that I can't get the non empty video tiles. There are no errors in console, meeting session perfectly esteblished via our custom AWS Lambda endpoint and the Logger shows, that everyting is working fine. Audio and Video devices are listed and atteched without any issues and the Chrome browser indicating the video capturing from camera with the red circle blinking on the related tab. But, there is no sign of data for rendering. Can you please tell what am I doing wrong?

Screenshots are attached below. Thanks in advance!
Best, A!

I have problems for deploying in cloud9, when execute:

Hi Team,

I am trying to running classroom demo on my local machine as per your Readme File.

So I got this error-
Failed to create bucket: {"status":1,"signal":null,"output":[null,{"type":"Buffer","data":[]},{"type":"Buffer","data":[109,97,107,101,95,98,117,99,107,101,116,32,102,97,105,108,101,100,58,32,115,51,58,47,47,97,119,115,45,99,104,105,109,101,45,99,108,97,115,115,114,111,111,109,45,100,101,109,111,45,112,98,32,85,110,97,98,108,101,32,116,111,32,108,111,99,97,116,101,32,99,114,101,100,101,110,116,105,97,108,115,10]}],"pid":137308,"stdout":{"type":"Buffer","data":[]},"stderr":{"type":"Buffer","data":[109,97,107,101,95,98,117,99,107,101,116,32,102,97,105,108,101,100,58,32,115,51,58,47,47,97,119,115,45,99,104,105,109,101,45,99,108,97,115,115,114,111,111,109,45,100,101,109,111,45,112,98,32,85,110,97,98,108,101,32,116,111,32,108,111,99,97,116,101,32,99,114,101,100,101,110,116,105,97,108,115,10]}}

After following the instructions detailed on the README file, using Cloud9 for build and deployment I got the following error:

error /home/ec2-user/environment/amazon-chime-sdk-classroom-demo/node_modules/electron-chromedriver: Command failed.
Exit code: 1
Command: node ./download-chromedriver.js
Arguments: 
Directory: /home/ec2-user/environment/amazon-chime-sdk-classroom-demo/node_modules/electron-chromedriver
Output:

    if (error != null) throw error
                       ^

Error: ENOSPC: no space left on device, write

My guess was that the EBS wasn't successfully resized when cloud9-resize.sh was called but, as far as I can tell the EC2 instance is using the right EBS with 100GB of space. I'm clueless
