Merge remote-tracking branch 'qatar/master'
* qatar/master: (40 commits) swf: check return values for av_get/new_packet(). wavpack: Don't shift minclip/maxclip rtpenc: Expose the max packet size via an avoption rtpenc: Move max_packet_size to a context variable rtpenc: Add an option for not sending RTCP packets lavc: drop encode() support for video. snowenc: switch to encode2(). snowenc: don't abuse input picture for storing information. a64multienc: switch to encode2(). a64multienc: don't write into output buffer when there's no output. libxvid: switch to encode2(). tiffenc: switch to encode2(). tiffenc: properly forward error codes in encode_frame(). lavc: drop libdirac encoder. gifenc: switch to encode2(). libvpxenc: switch to encode2(). flashsvenc: switch to encode2(). Remove libpostproc. lcl: don't overwrite input memory. swscale: take first/lastline over/underflows into account for MMX. ...
