Hello,

From time to time we are seeing an issue while receiving h264 video in Chromium: at some point PLI requests count increases rapidly to approx. 6 RPS, but key frames sent in response are not decoded and are being discarded. Video stream freezes, and can be restored only if P2P connection is re-established.

We cannot reproduce it consistently, and we only seen it in Chromium on macOS.
Sender side is a libwebrtc based application with h264 hardware nvidia encoder.

Will appreciate any help, thanks!

you might want to get a bitstream dump using the RTP dump instructions in the last comment on https://webrtchacks.com/video_replay/
and then check the bitstream (video_replay does not support hardware decoders sadly)
