ffmpeg-11656-alt1 (i586) would segfault on atta... er, linked (36M) MiniDV snippet at least when called as: ffmpeg -threads 1 -f dv -i capture2006.05.02_01-56-50.dv -pass 1 -passlogfile h264_dual.log -vcodec libx264 -g 300 -deinterlace -s 768x576 -aspect 4:3 -b 2048000 -ab 192000 -title -author -comment -copyright -y h264_dual.mp4 libx264 package is 0.58-alt0.745.1; the whole thing is happening when exporting from kino-1.3.0 (H.264 Dual Pass FFMPEG, Best/High Quality); there's also segfault when doing MP4 export but I'd better file that as a separate bug if anyone wishes.

2 thresh 4 astrange: nope, visually the same segfault with current snapshot; handling sample to led@ (could you pass the link upstream too?)
Some mencoder tests a few days ago show that segfault is there when sound is recoded too; nosound would result in proper video. I've rolled back libx264 and libfaac to 4.0/branch builds -- libx264: 0.58-alt0.20080320.1 -> 0.56-alt0.671.1 libfaac: libfaac-1.26-alt1 -> 1.25-alt3 and the same ffmpeg line as shown does work; upgrading libx264 again results in segfault again. Seems like a compound problem? As far as I understand mplayer would use ffmpeg to do a mp4 container, and disabling/enabling sound together with library rollback being important to working around the problem hints at that too.
PS: I've tried x264 git yesterday (failed to build latest commit but did build and test 32fb497 to no avail); could probably fiddle with faac as well but would be so much better to help you folks, as I'm not much into the intricacies of the whole software stack involved.
всё ещё актуально?
Предположительно да -- на днях обновил дома libx264 из M41, вскоре был уведомлён, что H.264 перестали экспортиться из kino. Вообще кучка страшных для libx264/mencoder образцов угрожающе выросла...
