Kurento Recorder doesn't write Screen Capture (getDisplayMedia stream) #630

Issue description

When using Kurento to capture user's screen, the video stream gets into the pipeline and can perform the full loopback but the recorder is not writing the stream to the file. The file is created and keeps 0 bytes always. The stream flows in the RecorderEndpoint but the recorder doesn't write buffered data to file. This is happening with "Kurento Tutorial: Loopback with recording using generators".

How to reproduce?

  1. In kurento-utils.js search for following code: 
            getScreenConstraints(sendSource, function (error, constraints_) {
            if (error)
                return callback(error);
            constraints = [mediaConstraints];
            constraints.unshift(constraints_);
            getMedia(recursive.apply(undefined, constraints));
        }, guid);
  2. Replace it by following code: 
                navigator.mediaDevices.getUserMedia(mediaConstraints).then(function (stream) {
                videoStream = stream;
                start();
            }).catch(callback);
  3. Go to your JS application and add option sendSource with value other than 'webcam': 
    var options =
{
localVideo: videoInput,
remoteVideo: videoOutput,
sendSource: 'screen'
}
  4. Run application.
  5. Loopback will work and show captured screen.
  6. Recording file is 0 bytes after stopping.

Expected & current behavior

KMS should write buffer data to file independently on streaming source.

Attached log output when recording is done using "getUserMedia" (sendSource: 'webcam'), removed all ICE negotiation except SDP exchanges. Timestamp of disconnection is 2022-07-08T10:11:34,885951

(attached in folowing comments because the reporting tool says body is too long)

Differences I see:

(Optional) Possible solution

Is there any flag marking Screen Capture and disabling recording?

Hello @RaistGH! :wave: we're sorry you found a bug... so first of all, thank you very much for reporting it.

To know about progress, check in Triage. All issues are considered Backlog Candidates until work priorities align and the issue is selected for development. It will then become part of our official Backlog.

Please follow the Troubleshooting RecorderEndpoint section of the doc, to see if any of the suggestions help you find the cause of the problem.

RaistGH commented 2 years ago

Thanks for so fast reply! I used the function connect(MediaElement, MediaType) (with MediaType matching 'AUDIO|VIDEO|DATA': yield webRtc.connect(recorder, 'VIDEO'); But it was not enough. Apparently RecorderEndpoint must be also built as video only so parameter mediaProfile must be set and matching 'WEBM|MKV|MP4|WEBM_VIDEO_ONLY|WEBM_AUDIO_ONLY|MKV_VIDEO_ONLY|MKV_AUDIO_ONLY|MP4_VIDEO_ONLY|MP4_AUDIO_ONLY|JPEG_VIDEO_ONLY|KURENTO_SPLIT_RECORDER|FLV'.

So, in addition to connect(recorder, 'VIDEO'), RecorderEndpoint creation would be: var recorder = yield pipeline.create('RecorderEndpoint', {uri: args.file_uri, mediaProfile: 'WEBM_VIDEO_ONLY'});

Alternatively it's also possible to use a Composite Hub which outputs all 'AUDIO', 'VIDEO' and 'DATA' streams even though input is only 'VIDEO', so RecorderEndpoint gets all needed to record (that's why other people in the related discussion weren't having the same issue):

var compositeHub = yield pipeline.create('Composite');
var hubPortInput = yield compositeHub.createHubPort();
var hubPortOutput = yield compositeHub.createHubPort();
yield webRtc.connect(hubPortInput);
var recorder = yield pipeline.create('RecorderEndpoint', {uri: args.file_uri});
yield hubPortOutput.connect(recorder);
yield hubPortOutput.connect(webRtc);
yield recorder.record();

Therefore instead of a functionality bug this can be changed to a Doc Improvement Request. Thanks!

Happy to see that you managed to make it work. I always take the chance to leave things better than they were, so docs have been revised:

Thanks for the feedback.

RaistGH commented 2 years ago

Thanks! I was trying to modify the docs this morning and do a pull request but I didn't have the time to finish it. Anyway what you wrote is more complete than mine :)
