[MPlayer-cvslog] r25817 - trunk/libmpdemux/demux_lavf.c

[rtogni]

Author: rtogni
Date: Sun Jan 20 13:57:53 2008
New Revision: 25817

Log:
Allow overriding the codec_tag for audio codecs, and always override 
codec_tag for PCM codecs (codec_id from lavf is correct, but the 
codec_tag may be non-zero and wrong).

Also fixes bugzilla #983
