Originally committed as revision 25796 to svn://svn.ffmpeg.org/ffmpeg/trunk
The new implementation is more compact, more correct and doesn't hurt
the eyes.

so extend decoder to output only one channel for it.
This fixes issue 2368.

This also allows to remove a linking dependency of libavfilter on
libavcodec.
Originally committed as revision 25789 to svn://svn.ffmpeg.org/ffmpeg/trunk
const char *avcodec_get_channel_name(int channel_id)
which was never implemented.

PaletteControl.
This also fixes playback of some files with ffplay (images were
corrupted for a short time after a palette change).

This makes the wording consistent with how people usually talk about heaps.

This increases the PSNR slightly (about 0.1 dB) for trellis sizes
below 8, and gives equal PSNR for sizes above that.

This lowers the run time from 158 to 21 seconds, for -trellis 8
with a 30 second sample on my machine.
This requires 64 KB additional memory.

beginning of the frame, so make it use skip_bits_long() instead of
skip_bits() for that.

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.
Originally committed as revision 25733 to svn://svn.ffmpeg.org/ffmpeg/trunk
This avoids having to memmove the large parts of the array when inserting into
it.
For -trellis 8, this lowers the run time from 245 seconds to 190 seconds,
for a 30 second 44 kHz mono sample, on my machine.

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

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.
Fixes issue 2352

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.
