This fixes a crash when seeking in some webm files with many
threads (e.g. 8).

FF_COMMON_FRAME holds the contents of the AVFrame structure and is also copied
to struct Picture.  Replace by an embedded AVFrame structure in struct Picture.

This macro can cause problems in conjunction with the bitdepth
template expansion.  It was presumably added to keep source
compatibility when high bitdepth support was added.  However,
emulated_edge_mc is a dsputil pointer and should not be called
directly, so there is little reason to keep such a macro.

Deprecate avcodec_alloc_context/2.

It should be replaced with proper per-codec defaults.

Deprecate corresponding AVCodecContext option.

This is the first test of decoder private options.

Adds support for decoder-private options and makes setting other options
simpler.

Instead, just decrease it to a valid value and use that.

libavcodec/libxvidff.c:752: warning: initialization discards qualifiers from pointer target type

Eliminate redundant check in filter_mb_fast, consider bit depth in calculating qp_thresh.

Inline the relevant parts of fill_decode_caches into P-SKIP mv prediction to
avoid calling the whole thing.

These weren't getting inlined all the time in all gcc versions.

Mainly ported from 8-bit H.264 predict.

Some code ported from x264. LGPL ok by author.

This is needed because not all players (e.g. MPlayer) are able to distinguish
two different Bink audio decoders when codec_tag is set.

As a positive side-effect, this gets rid of the following warning:
libavcodec/flashsv.c:190:38: warning: assignment discards ‘const’ qualifier from pointer target type

An official specification now exists and it is both more detailed and easier to
understand than the incomplete notes available here.  Also remove ideas on how
to implement an encoder; these notes are already present in the encoder.

This fixes the warning:

Some versions of the GNU assembler do not handle 64-bit
immediate operands containing arithmetic.  Writing the
value out in full works correctly.

This naming scheme is used elsewhere, so it's sensible to be consistent.

The Altivec IMDCT works with size 32 and higher only.

This function is called with only 8-byte alignment from
imdct for size 16.  The fft4 function is not called for
the larger FFT or MDCT sizes, so this has no impact on
typical uses.

Set the frame size when decoding DTS audio.

This has the side effect of fixing the computation of timestamps for DTS-HD in compute_pkt_fields.  Since frame_size is
not currently set, the duration of a frame is being guessed based on the streams bitrate.  But for DTS-HD, the bitrate
currently used is the rate of the DTS core which is much different than the whole DTS-HD stream and leads to a wildly
inaccurate frame duration estimate.
