* qatar/master:
  mpegvideo_enc: only allocate output packet when we know there will be output
  Add names for more channel layouts to the channel layout map.
  sunrast: Add a sample request for RMP_RAW colormap.
  avcodec: do not override pts or duration from the audio encoder
  Add prores regression test.
  Enable already existing rso regression test.
  Add regression test for "sox" format muxer/demuxer.
  Add dpx encoding regression test.
  swscale: K&R formatting cosmetics for PowerPC code (part I/II)
  img2: Use ff_guess_image2_codec(filename) shorthand where appropriate.
  Clarify licensing information about files borrowed from libjpeg.
  Mark mutable static data const where appropriate.
  avplay: fix -threads option
  dvbsubdec: avoid undefined signed left shift in RGBA macro
  mlpdec: use av_log_ask_for_sample()
  gif: K&R formatting cosmetics
  png: make .long_name more descriptive
  movdec: Adjust keyframe flagging in fragmented files
  rv34: change most "int stride" into "ptrdiff_t stride".

are taken from libjpeg, see the top of the files for licensing details.
* The files libavcodec/jfdctfst.c, libavcodec/jfdctint_template.c and
libavcodec/jrevdct.c are taken from libjpeg, see the top of the files for
licensing details. Specifically note that you must credit the IJG in the
documentation accompanying your program if you only distribute executables.
You must also indicate any changes including additions and deletions to
those three files in the documentation.
Should you, for whatever reason, prefer to use version 3 of the (L)GPL, then
the configure parameter --enable-version3 will activate this licensing option
