调研方向
Start by reproducing the issue in the example demo app with H264 selected, Android screen sharing as the publisher, and a remote participant viewing the track; compare with VP8. Then trace the Android screen-share publishing and H264 handling paths to find where remote video stops rendering. Done means remote participants render Android H264 screen-share video, while local rendering continues to work.

描述
Describe the bug
When using H264 with Android screen-share, the local participant will see the video rendered correctly in their local UI viewer. However, other remote participants instead see no video rendered/produced. Remote participants are notified of the new track being publish/subscribed, but the VideoTrackRenderer does not render any video.
VP8 is not impacted by this bug and works as intended.
iOS/Browsers are not impacted by this H264 bug when they are the publisher of screen-sharing.
Other OSs not tested.
To Reproduce
Switch the default codec to H264 within the example demo app. Try to share your screen on Android. I have also independently verified this bug behavior within my own private application.
Expected behavior
Android screen-share video should be rendered by remote participants, and not just the local participant.
