[Ffmpeg-cvslog] CVS: ffmpeg/libavformat mpegts.c,1.39,1.40

[Måns Rullgård CVS]

Update of /cvsroot/ffmpeg/ffmpeg/libavformat
In directory mail:/var2/tmp/cvs-serv19665

Modified Files:
	mpegts.c 
Log Message:
This patch simply adds demuxing support for AC-3 streams in DVB TS
files.  In these streams AC-3 is given type 0x06 (private stream) and
includes a descriptor with either tag 0x6A or 0x7A.  The code already
handles ATSC AC-3 which uses stream type 0x81.  All the new patch does
is look for any stream type 0x06 that has a descriptor with the proper
tag (i.e. 0x6A or 0x7A) and if found forces it to be recognized as an
AC-3 stream.
