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:
