It will be reused by the AAC decoder.

This fixes builds with vc1_parser enabled without vc1_decoder. All
the vc1_decoder object files were included in the vc1_parser line
in libavcodec/Makefile before, but architecture specific object files
for vc1_decoder were not.

Compared to existing, common opensource H264 encoders, this can be
useful since it has got a different license (BSD instead of GPL).

Performance- and qualitywise it is comparable to x264 in ultrafast
mode.

Hooking it up as an encoder in libavcodec also simplifies comparing
it against other common encoders.

This requires OpenH264 1.3 or newer. Since the OpenH264 API and ABI
changes frequently, only releases are supported.

To take advantage of the OpenH264 patent offer, the OpenH264 library
must not be redistributed, but downloaded at runtime at the end-user's
system.

vorbis_parser.o is built unconditionally since 5e80fb7ff, and the
unconditionally built parts of it depend on xiph.o.

This fixes builds with --disable-everything.

The only parameters needed by the demuxers are the sample rate and sample
count, which can be trivially extracted manually, without resorting to
an avpriv function.

It is required by (at least) the ogg demuxer.

Mark the current semi-public apriv API for removal.

Speed up the overall compilation time.

This makes the addition of arch optimized functions easier.

These are the only WMA bits shared with binkaudio. Splitting them off
reduces the binnkaudio dependency on general WMA code.

Initialise VC1DSPContext for parser as well as for decoder.
Note, the VC-1 code doesn't actually use the function pointer yet.

This permits re-use with parsers for codecs which use similar start codes.

The Xvid IDCT is only required to decode some Xvid-encoded MPEG-4 files,
so there is no point in having it as an unconditional part of idctdsp.

The only thing the demuxer needs is the sample rate to set the timebase,
which can be simply read with AV_RB32.

This obviates a dependency of the LJPEG encoder on mpegvideo.

eatqi uses more than just the shared mpegvideo bits.
