Hello!


Synopsis:

When mplayer should player a mpeg video, some of them result
in this:

MPEG-PS file format detected.
missing marker bit!
MPEG: bad sequence header
Video: Cannot read properties.
==========================================================================
Opening audio decoder: [mp3lib] MPEG layer-2, layer-3
AUDIO: 48000 Hz, 2 ch, 16 bit (0x20), ratio: 24000->192000 (192.0 kbit)
Selected audio codec: [mp3] afm:mp3lib (mp3lib MPEG layer-2, layer-3)
==========================================================================
...

and mplayer only plays the audio, but not the video.

VLC and Xine also claim about the missing marker bit, but
nonetheless they play the video.

With the attached patch, mplayer can do this, too.

This is the output with the patch:


MPEG-PS file format detected.
missing marker bit!
VIDEO:  MPEG1  480x576  (aspect 2)  25.000 fps  4280.4 kbps (535.0 kbyte/s)
