d2cbdb17b5 Re-implement avpicture_layout() using pixdesc and imgutils API.
The new implementation is more compact, more correct and doesn't hurt
the eyes.

7d3829a87a Musepack SV8 supports "mono" files (though it still codes them as stereo),
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

78f9d35c9a adpcm: Only increment heap_pos after finding a good enough sample

38b3bda18f adpcm: Replace any of the leaf nodes in the heap
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.

f82e8f3482 adpcm: Store the trellis nodes in a heap instead of a sorted array
This avoids having to memmove the large parts of the array when inserting into
it.

for a 30 second 44 kHz mono sample, on my machine.

8455e8c7c0 vorbisdec: Fix floor1 decoding
An intermediate value in the floor 1 linear interpolation was
overflowing
resulting in obvious artifacts on some files.

e.g.
http://upload.wikimedia.org/wikipedia/commons/7/79/Big_Buck_Bunny_small.ogv

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

2de6f6e828 Make avcodec_pix_fmt_string() use the information in the pixel format
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.
