[Ffmpeg-devel] Format bug or ffmpeg bug ?

[Anders Moden]

Hi !

I am desperatly trying to get some clarification of this problem. I have a file at http://www.gizmosdk.com/test.ts that I am unable to present correctly with ffmpeg. The frame rate is set to 100 fps and I get a load of errors parsing the file.

I use this command line as a test..
> ffmpeg -i test.ts


and I get this output...

The file is correctly played by vlc and by mencoder but with some errors as well.

Please ! Help. Is this a ffmpeg bug and how come the vlc and mencoder can play it correcly ? Am i missing something ?
