This makes the currently semi-public avpriv_aac_parse_header() function
private to libavcodec and adds a proper public API function to return
the parts of the ADTS header required in libavformat.

Only I-frames are decoded for now.

Takes a raw input stream containing frames with correct timestamps but
possibly out of order and inserts additional show-existing-frame
packets to correct the ordering.

From ffmpeg commit 2e6636aa87.

Deprecated in 11/2013.

Decodes YUV 4:2:2 10-bit and RGB 12-bit files.
Older files with more subbands, skips, Bayer, alpha not supported.

This moves work from the configure to the Make stage where it can
be parallelized and ensures that pkgconfig files are updated when
library versions change.

Additional scaling list handling fix by Jun Zhao <mypopydev@gmail.com>.

Partially based on code by Ronald S. Bultje <rsbultje@gmail.com>.

It is useful for testing/debugging and will also be used as the default
filter in the following commit adding pre-decode filtering to avoid
having a separate non-filtered codepath.

The feature has outlived is usefulness and complicates the code.

This allows expressing dependencies in a more correct way.

Fixes standalone compilation of the libmp3lame encoder.

It uses the same code as the MPEG-2 decoder, so the file is renamed
to contain all "other" (that is, not H.26[45]) codecs.

This is intended as a replacement for the 'split' function exported by
some parsers.

This is more consistent with the rest of libav and frees up the hevc.h
name for decoder-independent shared declarations.

Deprecates struct vaapi_context and the installed header vaapi.h,
to be removed at the next version bump.

Moves much of the setup logic for VAAPI decoding into lavc; the user
now need only provide the hw_frames_ctx.

The MP2 muxer uses none of the code of the MP3 muxer.

It is also used by the Dirac parsing code.

This fixes standalone compilation of the SVQ3 decoder, which had
incomplete dependencies related to H.264 parsing.

While it is less featureful (and slower) than the built-in H264
decoder, one could potentially want to use it to take advantage
of the cisco patent license offer.

There is no real advantage to listing some codecs or subsystems
separately simply because they are somehow "hw-accelerated", on the
contrary it makes them harder to find than in a plain alphabetically
ordered list.

Register mmaldec as mpeg2 decoder. Supporting mpeg2 in mmaldec is just a
matter of setting the correct MMAL_ENCODING on the input port. To ease the
addition of further supported mmal codecs a macro is introduced to generate
the decoder and decoder class structs.
