* 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
