  avformat/imfdec: inherit opaque from parent AVFormatContext
  
  io_open and io_close2 callbacks may use opaque pointer stored in the
  context. They are already inherited, so opaque should also be passed
  through.
  
  Fixes IMF playback in mpv.

  avformat/demux: use io_close2 when closing avfromat
  
  It's not valid to call avio_close() on context that has not been open
  with avio_open().
  
  This fixes use of custom IO. (io_open / io_close2 callbacks)
  
  Note that by default io_close2 is set to io_close2_default() which calls
  avio_close(), so default case will work the same as before.

  avcodec/mpeg12enc: Combine put_bits()
  
  This is a 16bit field in the spec, so using a single
  put_bits() to write it is more natural.

  avcodec/mpeg12dec: Remove nonsense comment
  
  Everything in mpeg12dec.c is about decoding.
