Sorry if previous message were missed. Perhaps your issue is specific to your
WebCam ? I don't owned myself a webcam that encodes to H264, so I've used
vaapih264enc, and performance was decent.

Asking question on public channels is an art, make sure to narrow down as much
as possible your issue, and try to think on how others will be able to
reproduce, if you can't make sure to share extra information that would allow
controlling the variable when simulating with audiotestsrc and similar.

regards,
Nicolas
