The buffer is used for an additional pass of frame compression, so videos
can be coded without ever using it (and some are coded so indeed, e.g. in
Woodruff and the Schnibble of Azimuth game).

libavutil/cpu.c:133:9: warning: unused variable ‘ret’ [-Wunused-variable]

Introduce ff_listen_connect, to be shared with the other
non-tcp network protocols.

Introduce ff_listen_bind, to be shared with the other non-tcp
network protocols.

Indeo 4 has quantiser range 0-31 instead of 0-23 for Indeo 5, and clipping
quantiser leads to incorrect quantisation and DC prediction on low-quality
videos.

This fixes bug 259.

Allows for easier handling of flags that may be specific to icl or msvc.
Furthermore, simplify the handling of warnings and remarks thanks to
icl's support of -Wall on Windows.

A few of the h264qpel neon functions are shared with other
hpeldsp functions in this file.

This fixes standalone compilation of the h264 decoder on arm.

Odd chunk size makes no sense for stereo and incomplete chunks are
not supported.

Simplify a little, assume empty frames are acceptable and
do not pointlessly reinit the bytestream2 contexts using
possibly wrong size values.

The modern MSVC for ARM always builds for thumb, and it can't be
disabled.

Also just use the default arch instead of trying to map the -march
parameter to MSVC's -arch parameter (which only takes the values
ARMv7VE and VFPv4).

The decoder did not start predicted frames with missing references but
called the end of frame handling on them anyway. This caused an
assertion in the VA API HW accelorator since it tried to render a
picture with uninitialized buffers.

This will be useful in the WavPack muxer.

It will be reused by other muxers and demuxers.

wv.c will be used for shared wavpack functions.

This way we don't require the caller to parse the block header. It also
allows the channel configuration to change mid-stream.

Since version 4.8 gcc sports asan and tsan integration that can

If building out of tree, make sure the filter scripts are copied
into the build tree before running tests. This makes sure that
SRC_PATH doesn't need to exist on the remote system (or doesn't
need to exist at the same path).

Currently if no custom block VLC is specified for band, a default block VLC
will be used, while the global block VLC stored in the context should be used
instead.

This fixes decoding of one sample I have.
