Yes. And MKV-files is stopped to fiil. > From the logs 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. I tried 30, 25, 20, 15 fps -- the same result: when MVK-files reeaces 2 GB, guvcview hangs up... > Also the matroska muxer caches audio frames so that matching audio and > video packets are stored in the same cluster. I doubt, that AVI is better... :-) > 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? Yes. 30, 25, 20, 15 fps... 960, 800, 640 pixels... [On a Core i5 processor.] > You should also test with different codecs and with the avi muxer, Yes, tried MPEG2, H264... The same... 2 GB... (on any FS: ntfs, ext3...) > also maybe with audio disabled, just to check if it makes any difference. I will try without audio... Thank you.
