Video track slow response and potential frame loss

Your environment.

• Version: 3.1.11+
• Browser: Chrome

What did you do?

I have two parties. The browser is the offerer and golang pion is to answer and pull phone screen and provide a video track to the browser. The connection is successfully connected and I can see the phone screen. When I swiped on the phone, the screen on the browser responded after 5-10 seconds and it looks like it dropped all intermediate video frames and only displayed the last one/several frames.

Both the video source and dst are on the same computer so it is not network related.

I inspect the chrome webrtc portal but didn't find any weird stuff. No dropped frames/packets detected.

If I used older version like 2.0.23, there is no issue. What could be the possible factor that I did wrong? Let me know what other information is needed. Thanks!

What did you expect?

The screen movement should be instant.

What happened?

Slow response and video loss.

Same here even if all images are encoded with H.264 I frame.
