Also add "volatile" to broadcast flag (since it is used from
multiple threads).

The muxer depends on the id3v2 writing code, so link against it.

The demuxer depends on the RIFF codec tags code, so link against it.

The demuxer depends on code from mov.c, which in turn depends on
code from mov_chan.c, so link against it.

A negative number of threads does not make sense and 0 is used for
autodetection. Adds a symbolic name for autodetection.

Use sched_getaffinity to determine the number of logical CPUs.
Limits the number of threads to 16 since slice threading of H.264
seems to be buggy with more than 16 threads.

This file does not use anything from get_bits.h but needs

The prefix is a historic remnant that probably meant "alternative".
Now that the A32 bitstream reader has been dropped it makes no sense anymore.

It's a part of public API.

fixes use of uninitialized values if the filter is still unstable after using
the previous frame lpc coefficients.

Fixes PAL8 to YUV conversion.

The 'fiel' atoms can be found in H.264 tracks clobbering the extradata.
MJPEG supports non field based extradata, and this data should be
preserved when copying.

fixes Bug 171

fixes memleak of side data

This fixes demuxing of file where the first packet is not audio. Such files
are generated by our idroq muxer. It also fixes demuxing of audio only
idroq files.

Compared to just overwriting the old extradata, this has the
advantage of letting the decoder know exactly when the
extradata changed (otherwise it is changed immediately when the
new extradata packet is demuxed, even if there's old queued packets
awaiting to be decoded). This makes it easier for decoders to
actually react to the change, so they won't have to inspect
the extradata for each packet to see if it might have changed.

This works when sequentially playing a file with sample rate
changes, but if seeking past a new extradata packet in the
file, it obviously doesn't work properly. That case doesn't
work in flash player either, so it's probably ok not to handle
it.

On 32-bit OS X with gcc 4.0/4.2 and shared libraries enabled, the ebx register
is not available, but required to assemble the functions.

This reverts commit 8742a4ff to a simplified version of the original constraints.

This fixes a deadlock VLC triggered with multithreaded decoding. The
wait forces one of the current waiters to wake and not the thread
which calls pthread_cond_signal() itself.
