works with mplayer -vc mpeg12 file

Could you provide some console output: It fails here with current MPlayer svn.

[Carl Eugen Hoyos]

Needs -demuxer lavf or -fps here.

[compn]

you need to compile mplayer with libmpeg2 for -vc mpeg12 to work.

heres output of extremely old mplayer with libmpeg2 built in

Replying to compn:

Of course.
But you also added -fps to your command line.

[compn]

yes, otherwise it says
FPS not specified in the header or invalid, use the -fps option.

There is still an issue when seeking (backwards).
