Merge remote-tracking branch 'qatar/master'
* qatar/master: indeo: Make ivi_calc_band_checksum() static, it is only used in one file. indeo: Drop unused debug function ivi_check_band(). avcodec/utils: cast a function argument to shut up a compiler warning truemotion1: remove disabled code fix typo in comment fate: fix dependencies for non-SAMPLES avconv tests indeo: check for invalid motion vectors indeo: check that band output buffer exists indeo: clear allocated band buffers indeo: track tile macroblock size indeo: check custom Huffman tables for errors factor out common decoding code for Indeo 4 and Indeo 5 mp3: fix start band index for block type 2 in 8kHz audio lavf: change some (de)muxer names to lowercase lavf: make output format matching case insensitive Conflicts: libavcodec/indeo4.c libavcodec/indeo5.c libavcodec/ivi_common.c libavcodec/utils.c tests/fate/video.mak Merged-by: Michael Niedermayer <michaelni@gmx.at>
