FFMPEG created WTV files cannot be fast forwarded or fast rewound in Windows Media Center

[ramitbhalla]

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.

[cehoyos]

In any case, please provide the command line you used to produce a test-file together with complete, uncut console output.

[ramitbhalla]

Sure:

This is just one file, I get the same result with any file.

ffmpeg -i "..\Himoe_USA_WRC-HD.ts" -c copy test.wtv

[cehoyos]

Does it only happen with -codec copy, or also if you re-encode?

[ramitbhalla]

With re-coding also, if I use -vcodec mpeg2video -acodec copy, I get the same result.

(ffmpeg WTV for now only supports MPEG2, I've submitted a request to support h.264)

[cehoyos]

Replying to ramitbhalla:

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...

[ramitbhalla]

WTV support for H.264 -> Ticket #1945 (been marked as duplicate of #536)

Here is the output of recoding, still the same issue while FF / RW:

ffmpeg -i "..\Himoe_USA_WRC-HD.ts" -vcodec mpeg2video -qscale 2 -acodec ac3 -ab 384k test.wtv

[ramitbhalla]

Wonder if anyone's noticed the votes this issue is getting ;)

[ramitbhalla]

Peter Ross any thoughts on this one? I know you had fixed this some time ago in Dec, FF is partly working now. Any idea why not completely?
