Our w32pthreads wrapper has various issues and is only supposed to be
used in libavcodec.

Allow using connection parameters in order to append arbitrary
AMF data like "B:1 S:authMe O:1 NN:code:1.23 NS:flag:ok O:0" to the
Connect message. You can pass these parameters through the -rtmp_conn
option.

When there are multiple input files, run demuxing for each input file in
a separate thread, so reading packets does not block.

This is useful for achieving low latency when reading from multiple
(possibly slow) input streams.

Fix build after b74a1da4.

Override the frame size from the SPS with AVCodecContext values
if the latter specify a size smaller by less than one macroblock.

Unlike its predecessor, Indeo Audio codec generates tables depending on
sampling rate. Previously decoder used pre-generated tables for 22050 Hz
which obviously doesn't work with other frequencies.

Many thanks to Maxim Poliakovsky for providing all needed information
for this.

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.

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.
