- While a track is muted, its RTP clock keeps running, for audio and video. The
first packet after an unmute shows the length of the mute (RFC 3550). Before,
the timestamps continued from the last packet before the mute.
- `RemoteTrack::next_video_frame` decodes the VP9 SVC that browsers send in
flexible mode. Before, it gave the first frames and then no more frames: the
depacketizer kept the reference indices of earlier packets and rejected each
inter frame after the third reference index.
- `RemoteTrack::next_video_frame` asks the publisher for a keyframe when
packets arrive but no frame is decoded for 3 s, and again after each further
3 s, as libwebrtc does. Before, a stream whose frames could not be assembled
stayed frozen and sent no keyframe request.
