[gst-devel] libmpeg2 problem

[vishnu at pobox.com]

Here's the patch i made to verify that libmpeg2 is not getting restarted
after a DISCONTINUOUS event : mpeg2dec->decoder->is_sequence_needed = 1;

Basically, as soon as is_sequence_needed gets set, i stop getting
vo * frame warnings even though g_warning ("mpeg2dec with %d", size);
keeps showing more data getting pumped into libmpeg2.

This only happens with mpeg1.  mpeg2 works flawlessly.  i'm using
mpeg2dec-0.2.0.tar.gz and current gstreamer CVS.
