New Revision: 8688

Modified:
   trunk/libavcodec/h264.c

Log:
scenario: A properly coded frame is followed by an end of sequence NAL unit,
i.e. the four bytes 00 00 01 0a.
When decode_nal() decodes the end of sequence NAL unit, it returns with
dst_length == 0. The original code leads to a return -1 which discards
the current properly decoded frame.
