The comment should have been placed only in
yuv2rgb48_X_c_template, not yuv2rgb48_1_c_template.

This is part of the Great Evil Plan to simplify swscale. Note that
you'll see some code duplication between the output functions for
different RGB variants, and even between packed-YUV and RGB
variants. This is intentional because it improves readability.

YUV planes were marked as uint16_t, but they contained signed data.

The H.264 parser that we use to detect interlacing can only handle
an Annex B stream, so we need to actually use the filter. This is
unfortunate as the crystalhd library is already doing this conversion
internally. A future change will reorganise the decode path more
completely so that we can feed the converted stream into libcrystalhd
and avoid the second conversion.

In preparation for using the filter on the actual bitstream, we need
to extend it's lifetime to match that of the decoder.

It was broken in 4:4:4, and still did chroma deblocking for no reason in 4:2:0.

Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.

* qatar/master: (24 commits)
  utils: Drop pointless '#if 1' preprocessor directive.
  ac3enc: remove empty ac3_float function that is never called
  ac3enc: split templated float vs. fixed functions into a separate file.
  ac3enc: dynamically allocate AC3EncodeContext fields windowed_samples and mdct
  ac3enc: use function pointer to choose between AC-3 and E-AC-3 header output functions.
  Roll back 4:4:4 H.264 for now Needs some ARM/PPC asm modifications.
  Fix SVQ3 after adding 4:4:4 H.264 support
  H.264: fix CODEC_FLAG_GRAY

  h264_parser: Fix whitespace after previous change.
  h264_parser: Fix behaviour when PARSER_FLAG_COMPLETE_FRAMES is set.
  wav: remove an invalid free().
  lavf: initialise reference_dts in av_estimate_timings_from_pts.
  h264: don't be so picky on decoding pps in extradata.
  avcodec.h: add or elaborate on some documentation comments.
  h264: change a few comments into error messages
  ac3dec: fix doxy-style for comment ("///>" should be "///<" instead).

sizeof(SampleType) is different for fixed and float encoders.

Function pointers are used for templated functions instead of needlessly
duplicating many functions.

This will allow the same struct to be used for both the fixed and float ac3
encoders.

Currently, the parser is buggy and only processes the stream extradata
when the flag is set. This fixes it to actually inspect the frames.

Whitespce will be fixed in a separate change.
