Merge remote-tracking branch 'qatar/master'

* qatar/master:
  dxva2: don't check for DXVA_PictureParameters->wDecodedPictureIndex
  img2: split muxer and demuxer into separate files
  rm: prevent infinite loops for index parsing.
  aac: fix infinite loop on end-of-frame with sequence of 1-bits.
  mov: Add more HDV and XDCAM FourCCs.
  lavf: don't set AVCodecContext.has_b_frames in compute_pkt_fields().
  rmdec: when using INT4 deinterleaving, error out if sub_packet_h <= 1.
  cdxl: correctly synchronize video timestamps to audio
  mlpdec_parser: fix a few channel layouts.
  Add channel names to channel_names[] array for channels added in b2890f5
  movenc: Buffer the mdat for the initial moov fragment, too
  flvdec: Ignore the index if the ignidx flag is set
  flvdec: Fix indentation
  movdec: Don't parse all fragments if ignidx is set
  movdec: Restart parsing root-level atoms at the right spot
  prores: use natural integer type for the codebook index
  mov: Add support for MPEG2 HDV 720p24 (hdv4)
  swscale: K&R formatting cosmetics (part I)
  swscale: variable declaration and placement cosmetics
