It turns out that this frame type is actually intra and should be used as
a reference for interframes too.

Needed to properly export avpriv_* symbols.

Also include config.h so that HAVE_ALTIVEC will be defined.
Fixes compilation on PPC with Altivec enabled.

Move vector_fmul() from DSPContext to AVFloatDSPContext.

This will allow for easier implementation of Altivec functions in libraries
other than libavcodec.

This will allow for easier implementation of ARM-optimized functions in
libraries other than libavcodec.

This ensures that these functions are inlined into the per-position
entry points, allowing constant propagation as needed for proper
optimisation.

A number of systems do not implement freopen() with a NULL filename
correctly.  This changes these programs to output individual images
if opening a named output argument as a file fails, in this case
assuming it is a directory.

Duplicate values in this vector are explicitly banned by the Vorbis I spec
and cause divide-by-zero crashes later on.

This will be useful for Indeo Audio decoder which is almost the same
but supports stereo.

They are only useful inside filters and we don't allow user filters for
now.

We do not allow user filters, so avtools shouldn't use them either.

It also allows to reuse buffer management code from avconv, thus
reducing duplication.

It will be used by avplay.

Use just the pointer to the head of the buffer pool.

This will allow sharing the code with avplay.

frame number should never be strictly larger than max frames, so the
if() was never triggered.

In Musepack SV8 codec property tell the maximum nonzero band, but every
frame codes maximum band as a limit (i.e. strictly less than given value).
Synthesis also expects maximum nonzero band, so there's a need to convert
frame maximum band limit value.

The specs say they are unsigned 32bit integers.

There may be multiple frames returned, so with just one check we can
write more than requested to the output.

They are not used outside of avfiltergraph.c

This makes it easier to switch between native rtmp and librtmp.

This makes decoder handle random data passed as BMV frame data.

Use correct side data size instead of just zeroed field.
