Merge remote-tracking branch 'qatar/master'
* qatar/master: h264: error out on invalid bitdepth. aacsbr: use a swap index for the Y matrix rather than copy buffers. huffyuv: do not abort on unknown pix_fmt; instead, return an error. lcl: return negative error codes on decode_init() errors. rtpenc: Use MB info side data for splitting H263 packets for RFC 2190 h263enc: Add an option for outputting info about MBs as side data avpacket: Add a function for shrinking already allocated side data nellymoserdec: Saner and faster IMDCT windowing Conflicts: doc/APIchanges libavcodec/avpacket.c libavcodec/version.h Merged-by: Michael Niedermayer <michaelni@gmx.at>
