#2078(undetermined:new): FFMPEG created WTV files cannot be fast forwarded or fast rewound in Windows Media Center
#2078: FFMPEG created WTV files cannot be fast forwarded or fast rewound in Windows Media Center -------------------------------------+------------------------------------- Reporter: ramitbhalla | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: Any WTV file created by FFMPEG, they can be seeked directly in MCE but when one tries toe fast forward or rewind (using the FF and RW buttons on the remote or the console) it does not go beyond at best 1 FF or 1 RW. i.e. WTV files recorded by MCE one can press the FF button upto 4 times to get 4x fast forward. Files created by FFMPEG sometimes get 1x FF and never go beyond 1x FF, it just returns to normal play. This happens with any WTV file, so you can take any file you have in your archive and remux it to wtv and see the results. something as simple as: ffmpeg -i test.ts -c copy test.wtv I'm not uploading a sample since it can be reproduced with any file remuxed to WTV. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/2078> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

With re-coding also, if I use -vcodec mpeg2video -acodec copy, I get the same result.
What about -acodec mp2 or -acodec ac3 ?
(ffmpeg WTV for now only supports MPEG2, I've submitted a request to support h.264)
I was under the impression trac user ianken submitted the request... -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/2078#comment:5> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
