[FFmpeg-cvslog] r17520 - trunk/libavcodec/h264.c

[reimar]

Author: reimar
Date: Sun Feb 22 10:51:58 2009
New Revision: 17520

Log:
Check return value of frame_start(), this avoids a crash if AVCodecContext::get_buffer failed.
Not sure if returning -1 is the best possible solution but at least avoids the crash.
