Step-1: SurfaceViewRenderer cannot be converted to Callbacks about webrtc-android-codelab HOT 8 OPEN

Hello @niroj08 ,
according to the official Android WebRTC example here (which is, unfortunately, a little bit complicated) you should create a private class which extends VideoSink:

private static class ProxyVideoSink implements VideoSink { private VideoSink target; @Override synchronized public void onFrame(VideoFrame frame) { if (target == null) { Logging.d(TAG, "Dropping frame in proxy because target is null."); return; } target.onFrame(frame); } synchronized void setTarget(VideoSink target) { this.target = target; } }

Then, you need to create it:
private final ProxyVideoSink localProxyVideoSink = new ProxyVideoSink();

and instead of adding a new render you add this sink to local video track:
localVideoTrack.addSink(localProxyVideoSink);

@soommy12 thank you! Your comment helped me a lot.

I tried to cast it to VideoRender.Callback as IDE suggested but then casting error occurs. Without that line I got a black screen but Logging says something like that:
I/org.webrtc.Logging: CameraStatistics: Camera fps: 31. and gives this lines with different fps (around ~30) consistently.

@vivek1794 can you please take a look at this?

from webrtc-android-codelab.

yes . vivek worked on this project like 4 months ago. many things changed in Webrtc library after that. change dependency version. here and it should work for you

implementation 'org.webrtc:google-webrtc:1.0.21710'

@jolsondc thanks, but I figured out how to do this using the newest version

from webrtc-android-codelab.

@soommy12 would have been great if you had posted your solution as well

My fps is only 17!

CameraStatistics: Camera fps: 17. and don't know why...
