Is there any way to support screen sharing that I want to achieve

[liusuyi2021]

I have now implemented a WebRTC connection and made audio and video calls. During the call, I would like to modify the local stream into a screenshot and send it in real-time. Is there any implementation plan? Thank you

Here's the code for the test pattern video source. It's effectively a static image with some dynamic adjustments and then streamed.

As far as switching between the sources the key is to make sure they are using the same video encoding and then something like (note I have not tested this code):

var winVideoEP = new WindowsVideoEndPoint(new VpxVideoEncoder(), WEBCAM_NAME);
var videoEncoderEndPoint = new VideoEncoderEndPoint();
var testPatternSource = new VideoTestPatternSource();

MediaStreamTrack videoTrack = new MediaStreamTrack(videoEncoderEndPoint.GetVideoSourceFormats(), MediaStreamStatusEnum.SendRecv);
pc.addTrack(videoTrack);

// Sending webcam samples. Disconnect event to stop.
winVideoEP.OnVideoSourceEncodedSample += pc.SendVideo;

// When you want to send your image samples activate something like the below.
//testPatternSource.OnVideoSourceRawSample += videoEncoderEndPoint.ExternalVideoSourceRawSample;
//videoEncoderEndPoint.OnVideoSourceEncodedSample += pc.SendVideo;
