08/11/2023, 2:12 AMI have a lot of evidence pointing to the cause - when a video track starts or stops, the sfu inserts a blank frame to ensure smooth transitions to/from no data (many players will just freeze the last frame until the next one comes in). There seem to be timestamping issues with these frames

08/11/2023, 8:20 AMFixed here - https://github.com/livekit/server-sdk-go/pull/291. It was an issue where gstreamer was waiting to process packets which were (incorrectly) timestamped hours into the future

08/11/2023, 7:12 PMRaja also put in some work on the SFU side to fix the source of the incorrect timestamps, my fix was more of a backup. Glad it’s finally working though!
