Comment 48 for bug 1373221

Hi,
What do you mean by "hang up" ?
Does the control window becomes unresponsive?

From the logs all I notice is that the capture ring buffer gets full,
this usually means frames are not being encoded fast enough. Guvcview
tries to compensate for this, by reducing the frame rate.
Also the matroska muxer caches audio frames so that matching audio and
video packets are stored in the same cluster.
In this case for some reason video frames are not being fed to the
muxer, so audio keeps filling the cache.
Have you tried reducing the resolution, or fps?
You should also test with different codecs and with the avi muxer,
also maybe with audio disabled, just to check if it makes any
difference.

Regards,
Paulo
