By not looking for the exactly largest node, we avoid an O(n) seek through
the leaf nodes. Just pick one (not the same one every time) and try replacing
that node with the new one.
For -trellis 8, this lowers the run time from 190 to 158 seconds,
for a 30 second 44 kHz mono sample, on my machine.

This avoids having to memmove the large parts of the array when inserting into
it.

An intermediate value in the floor 1 linear interpolation was
overflowing
resulting in obvious artifacts on some files.

Prior to this fix 87 out of 128 64kbit/s mono files decoded with ffmpeg
have
lower PEAQ ODG values than the same files decoded with libvorbis. With
this
fix none of that set have significantly worse ODG values than libvorbis.

Nobody ever uses it correctly, and ffmpeg sets it incorrectly, so we'll just
leave it out.

descriptors for printing the number of channels/components.
Also replace the term "nb_channels" with "nb_components" which is more
consistent with the FFmpeg internal terminology, and is somehow
different with respect to the current definition of nb_channels in
PixFmtInfo.
See thread:
Subject: [FFmpeg-devel] [PATCH 6/8] Make avcodec_pix_fmt_string() use the
information in the pixel format descriptors for printing the
number of planes. Also replace the term "nb_channels" with
"nb_planes" which is more correct.

eval API.
More grep-friendly and more consistent with the rest of the FFmpeg
API.
Originally committed as revision 25708 to svn://svn.ffmpeg.org/ffmpeg/trunk
The new name is shorter and more consistent with the FFmpeg API, and
sounds less evil.

avfilter_graph_parse() declaration to libavfilter/avfiltergraph.h.
Simplify, and less confusing for the user.

This new version:
1. Works on 24-bit and 32-bit input, not just 32-bit.
2. Doesn't try to run on 16-bit or 8-bit, instead of outright crashing.
3. Does proper alpha-blending, so cursor shadows look correct.
4. Doesn't swap R and B.
Mostly fixes issue 1997.
Fixes issue 2056.

Muxlength does not include the 3 bytes of AudioSyncStream() before the
AudioMuxElement(). If these three bytes are not accounted for the last three
bytes of the LATM packet are sent back to the decoder again.
