[Ffmpeg-cvslog] r6296 - in trunk: ffmpeg.c libavcodec/utils.c

[takis]

Author: takis
Date: Wed Sep 20 10:34:13 2006
New Revision: 6296

Modified:
   trunk/ffmpeg.c
   trunk/libavcodec/utils.c

Log:
Remove the "bf" OptionDef parameter so the equally named AVOption will take
over. Move over ffmpeg.c constraint checking, but allow value of zero to disable
B-frame.
