Problem with AtoB loop in mkv-files by mkvmerge
Posted: 21 Nov 2010 10:06
This behavior happens very often, but not always: After starting a loop for example from 10 sec to 14 sec, then playback jumps back to 9 sec and loops to 9.2 sec.
This may be related to Bug #3942, since chapters in the mkv file often make it worse and turning off ordered chapters improve the behavior.
I have tested this with version vlc-1.2.0-git-20101120-0002-win32 and with 1.1.3 on Debian sid, but I know it since a long time.
I have prepared some files, which you can download here: http://hanamana.de/AtoB-bug.zip.
clip-ffmpeg.mkv is produced by kdenlive (0.7.8 ) with ffmpeg (version SVN-r24504) and does not show the problem. ffmpeg-startup.log is the debug log from opening the file and ffmpeg-AtoB.log is the debug output during an AtoB loop.
clip-mkvmerge.mkv (by mkvmerge GUI v2.7.0 with mkvmerge v2.7.0 on Debian Sid), mkvmerge-startup.log and mkvmerge-AtoB.log are the files which show the error.
Finally clip-mkvmerge-chapters.mkv is a file which contains some chapters.
