* qatar/master: (26 commits) avconv: deprecate the -deinterlace option doc: Fix the name of the new function aacenc: make sure to encode enough frames to cover all input samples. aacenc: only use the number of input samples provided by the user. wmadec: Verify bitstream size makes sense before calling init_get_bits. kmvc: Log into a context at a log level constant. mpeg12: Pad framerate tab to 16 entries. kgv1dec: Increase offsets array size so it is large enough. kmvc: Check palsize. nsvdec: Propagate errors nsvdec: Be more careful with av_malloc(). nsvdec: Fix use of uninitialized streams. movenc: cosmetics: Get rid of camelCase identifiers swscale: more generic check for planar destination formats with alpha doc: Document mov/mp4 fragmentation options build: Use order-only prerequisites for creating FATE reference file dirs. x86 dsputil: provide SSE2/SSSE3 versions of bswap_buf rtsp: Remove some unused variables from ff_rtsp_connect(). avutil: make intfloat api public avformat_write_header(): detail error message ...
