[MPlayer-dev-eng] [PATCH] Improving audio handling when using edl with mencoder

when encoding PES files, the necessary audio to fetch before an edl cut is  
computed using

   mux_v->timer + next_edl_record->start_sec - demuxer->video->pts

within the function stop_time of mencoder.c. demuxer->video->pts turns out  
to be 0, if the previous PES packets do not contain timestamps. In such  
cases, the computed value is far too big and finally far too much audio  
get muxed.

The attached patch replaces demuxer->video->pts by the pts stored in the  
video stream header. However, as the pts stored in the demuxer is not yet  
completely clear to me, I am not sure, whether the patch is appropriate.
However, for my test files, this patch cut down superfluous audio from 0.8  
to 0.06 seconds.

Kind regards,
