[FFmpeg-cvslog] r20137 - trunk/libavformat/raw.c

[reimar]

Author: reimar
Date: Fri Oct  2 08:40:50 2009
New Revision: 20137

Log:
Return any error return values from av_get_packet, get_buffer etc. unchanged
in the raw demuxers.
Also remove special handling of 0-size reads, if they are due to an error/eof,
these are already converted to the appropriate error by get_buffer.
