This makes the DCA parser and decoder independent.

Fixes linking when only a subset of the deprecated vdpau decoders is
enabled.

Allows use of AVHWAccel based decoders with frame based multithreading.
The decoders will be forced into an non-concurrent mode by delaying
ff_thread_finish_setup() calls after decoding of the current frame
is finished.

This wastes memory by unnecessarily using multiple threads and thus
copies of the decoder context but allows seamless switching between
hardware accelerated and frame threaded software decoding when the
hardware decoder does not support the stream.

Since c977039e plane count for
PIX_FMT_HWACCEL pixel formats is 0 instead of 1. The created dummy
AVBuffers are still bogus since AVFrame does not hold frame data when
AVHWAccels are used.

No such encoder exists currently.

Error resilience is enabled by the h264 decoder, unless explicitly
disabled. --disable-everything --enable-decoder=h264 will produce
a h264 decoder with error resilience enabled, while
--disable-everything --enable-decoder=h264 --disable-error-resilience
will produce a h264 decoder with error resilience disabled.

Also move the declaration to internal.h, and add restrict qualifiers
to the declaration (as in the implementation).

This allows dropping the mpegvideo dependency from a number of
components.

This also fixes standalone building of the h264 parser, which
was broken in 64e43869.

Fixes fate errors in asv1, ffvhuff and huffyuv on x86_32.

This is necessary after the old av_gettime in libavformat was
dropped.

Fixes fate big endian configs.

Tests the workaround added for 1080 videos created with Canon cameras
in 30f51509.

This patch improves af_asyncts behavior on streams with bogus PTS, which
are either non-monotonic, or contain PTS jitter, and trigger the
non-monotonicity error. With this patch, af_asyncts is able to correct
these streams and avoid the error.

Firstly, it fixes resample compensation calculation by supplying proper
units to avresample_set_compensation (sample count per second instead
of sample count per some arbitrary frame size). Also, the calculation of
the compensation itself is fixed - delta is proportional to an adjustment
of the compensation, not the compensation itself. Ideally, the compensation
should converge to a value that keeps delta at zero.

To be able to deal with sources with PTS jitter even without resampling,
small PTS errors are adjusted, so the output frames do not overlap.

Finally, one more monotonicity check is added.

The FATE reference changes because now there is 8 less samples of
silence because of the pts jitter.
