#1338(undetermined:new): FFMPEG creating broken MP4/Audio files with LibXvid
#1338: FFMPEG creating broken MP4/Audio files with LibXvid -------------------------------------+------------------------------------- Reporter: ramitbhalla | Type: defect Status: new | Priority: important Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- The latest version of FFMPEG (N-40824-g31dfe20) is creating broken MP4 files when starting with a TS file. The Audio is completely out of sync or creates no audio at all. This is a regression bug so I'm marking it important. This was working with FFMPEG build N-37915-g6cb2085 with no audio issues. Attaching the link to the input file (it is 40MB in size unfortunately to be able to replicate the issue). http://www.mediafire.com/?5xwf84kbzp6ci4y You can replace libvo_aacenc with ac3 and it still has the same problem. If I put -vn the audio comes back (but there's no video). Some reason the Audio/sync is broken after build N-37915-g6cb2085.

KMPlayer is not able to play the file while WMP does not have any audio for quite a while after which it suddenly appears but out of sync. Unfortunatley yes all the parameters are required. If I remove all the params (say use only -sameq it works but the quality is terrible). The previous version of ffmpeg works perfectly with these params. I tend to update ffmpeg every few months, upto N-37915-g6cb2085 there was no issue, somewhere after that it broke (unfortunately I do not know how to use bisect etc to figure it out). Also mpeg4 codec quality for the same bitrate creates more artifacts so my users insist on using lix264. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1338#comment:4> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

Thanks, but like I had mentioned earlier the users are insisting on using lix264. Did you already confirm that the problem happens with libx264 but not with mpeg4 ? If yes, which options from your command line can be removed and which are essential to reproduce the problem?

there are several options git bisect or try to remove each command line option at a time to find the absolute needed set to reproduce it or analyze the output file to find out what is broken if anything. there may be other options, but most ffmpeg developers dont have windows so its kinda difficult for us to test/fix this. Also if you can confirm that it works with mpeg4 this itself may also be usefull to circle in on the bug ... -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1338#comment:9> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
