Hi, I build myself a mythtv based VCR and am struggling with small skips inplayback (both LiveTV and Recordings).
Hardware: * Shuttle ST62K Barebone / 512MB RAM / Celeron 2.4GHz * Terratec Cinergy 400TV * SEAGATE ST3160023A - 160GB (see also http://www.bb-zone.com/misc/LinuxPVR/ for a more detailed writeup on my little project). I tried all the hints I found. I changed the resolution, the MPEG4 bitrate, sync on video, etc. nothing really helped. System load is arounf 40%,with peaks at 90%. I couldn't make out any connection between the load peaks and the skips in the stream though. Starting the forntend with '-v playback,libav' I see this leading to the pause: 2004-12-31 00:23:12 A/V diverged by -13.0982 frames, dropping frame to keep audio in sync 2004-12-31 00:23:12 A/V diverged by -12.1487 frames, dropping frame to keep audio in sync 2004-12-31 00:23:12 A/V diverged by -11.1865 frames, dropping frame to keep audio in sync 2004-12-31 00:23:12 A/V diverged by -10.2211 frames, dropping frame to keep audio in sync 2004-12-31 00:23:12 A/V diverged by -9.24708 frames, dropping frame to keep audio in sync 'video_output' mean = '33336.56', std. dev. = '20322.25', fps = '30.00' avsync_delay: -253, avsync_avg: -369, warpfactor: 0.979771, warpfactor_avg: 0.998735 2004-12-31 00:23:12 A/V diverged by -8.2728 frames, dropping frame to keep audio in sync 2004-12-31 00:23:12 A/V diverged by -7.29835 frames, dropping frame to keep audio in sync 2004-12-31 00:23:12 A/V diverged by -6.3175 frames, dropping frame to keep audio in sync 2004-12-31 00:23:12 A/V diverged by -5.33813 frames, dropping frame to keep audio in sync 2004-12-31 00:23:12 prebuffering pause 2004-12-31 00:23:12 waiting for prebuffer... 2004-12-31 00:23:12 prebuffer wait timed out.. 2004-12-31 00:23:12 waiting for prebuffer... 2004-12-31 00:23:12 A/V diverged by -4.35358 frames, dropping frame to keep audio in sync 2004-12-31 00:23:12 A/V diverged by 3.625 frames, extending frame to keep audio in sync Any hints welcome!
