François Revol	8fa36ae09d	This fixes error handling for BeOS, removing the need for some ifdefs. AVERROR_ defines are moved to avcodec.h as they are needed in there as well. Feel free to move that to avutil/common.h. Bumped up avcodec/format version numbers as though it's binary compatible we will want to rebuild apps as error values changed. Please from now on use return AVERROR(EFOO) instead of the ugly return -EFOO in your code. This also removes the need for berrno.h.

Aurelien Jacobs	75c998a219	force usage of ALT_BITSTREAM_READER where needed Originally committed as revision 6118 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Roman Shaposhnik	56419683b2	I still don't think this should be here. Note: without this code DV encoder will accept incorrect pix_fmt's and such, but decoder will work much better with containers not setting the same attributes. It seems like there will be a generic mechanism for checking such constraints, but if not I can always resurrect this check for encoder only.

Dan Maas	6df5f6ae51	size[0-3] are not initialized (and can get random negative trash values), so the comparison with vs_total_ac_bits is messed up on the first couple loop iterations, leading to AC underflows. the b->prev[] pointers were not being maintained correctly. We potentially have to update b->prev[] both before and after the area whose VLC length is getting adjusted. this also might fix the ppc regression failure? patch by (Dan Maas <dmaas maasdigital com>) Originally committed as revision 5064 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Roman Shaposhnik	aa06658248	Moving dv_anchor back to the global scope. This creates a tiny memory leak for cases like dlopening libavcodec.so and such, but I still don't know how to catch such events. Originally committed as revision 4818 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
