Rejected. You have not provided sample(s). How could you be sure that only the marker bit is broken? After all it is the only check for this header. If only the beginning is broken then mplayer should advance until it finds good header. If the samples are encoded with bad encoder, then I'm sorry for you.

Do you really expect me to attach several videos with about 100MB each ? I don't think so. Thus, I provided the mplayer console output which showed that mplayer detected and played the video.
How could you be sure that only the marker bit is broken?
I'm not sure. I have two MPEG-PS musicvideos with the 'missing marker bit' and mplayer makes no troubles.
After all it is the only check for this header.
Well, it plays the videos nicely with my patch. And that's enough for every user. It may be that this or that pixel is shown wrong, but hey, do your eyes make notice of them ?
If only the beginning is broken then mplayer should advance until it finds good header.
If a good header exists at all. The question is, is this bit really needed ? mplayer seems to detect the mpeg format nonetheless.
If the samples are encoded with bad encoder, then I'm sorry for you.
I take this as 'use Xine or VLC if you are not happy with mplayer'. The videos have been captured from TV, btw ...

You don't have to attach it. Just cut out a piece small enough to exhibit the problem and upload it to our FTP server as described in bugreports.html.

Easy. Patches do not get accepted blindly here, they are reviewed first. This is what happened. Just answer the comments, upload a sample and maybe update your patch. It's the normal review cycle and it is not uncommon for a patch to get rejected several times before inclusion. Diego

This is a cut (first 5MB) of the video: ftp://mplayerhq.hu/MPlayer/incoming/goodbye.small.mpg This video cut should not play w/o my patch. This video cut plays nicely _with_ my patch. And this is a small description: ftp://mplayerhq.hu/MPlayer/incoming/goodbye.small.mpg.txt See my first mail where on I attached the patch for mplayer output. -- NEU +++ DSL Komplett von GMX +++ http://www.gmx.net/de/go/dsl GMX DSL-Netzanschluss + Tarif zum superg�nstigen Komplett-Preis!

Just tested, yes, it plays fine with your patch and fails without, xine also plays it without problems. Ivan, could you have another look at it? Diego
