Stream record FPS problem

[Gabriel Gonçalves]

I am having some problems on stream recording of webm video.

A few days ago some of the recorded videos started to return 1000/1 as fps on metadata, but on reality the video have 20-30 fps (webm format), on session creating, i am using "constraints:{video:{frameRate:30},audio:true}" to limit the frame rate to 30.

Good day.
WebRTC may change FPS depending on channel bandwidth and quality. So effective FPS may differ from value set in constraints.
Please clarify:
- what WCS build do you use?
- what data ffprobe shows for the file?

ffbprobe file.webm

- how this file is playing: are there freezes, artifacts etc?
Please also check how the stream to be recorded is playing: are there freezes, artifacts etc? Check the stream metrics. If VIDEO_NACK and VIDEO_LOST values grow, the publisher channel quality is probably bad. In this case, consider to use lower resolution/bitrate to publish, or use TCP transport:

session.createStream({
    name: streamName,
    display: localVideo,
    ...
    transport: "TCP"
    ...
}).publish();
