* g722: Add a trellis encoderMartin Storsjö2010-12-03
| | | | | | The structure is largely based on the trellis encoder in adpcm.c. Originally committed as revision 25866 to svn://svn.ffmpeg.org/ffmpeg/trunk

* adpcm: Skip samples whose ssd calculation has wrapped aroundMartin Storsjö2010-12-01
| | | | | | | | | | | | | | | Wraparound in ssd is mainly avoided by subtracting the ssd of the best node from all the others once it has grown large enough. If using very large trellis sizes (e.g. -trellis 15), the frontier is so large that the difference between the best and the worst is large enough to cause wraparound, even if the ssd of the best one is subtracted regularly. When using -trellis 10 on a 30 second sample, this causes only a slight slowdown, from 61 to 64 seconds. Originally committed as revision 25858 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Re-implement avpicture_layout() using pixdesc and imgutils API.Stefano Sabatini2010-11-21
| | | | | | | The new implementation is more compact, more correct and doesn't hurt the eyes. Originally committed as revision 25792 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Replace "depth" with "nb_bits" in the header of avcodec_pix_fmt_string().Stefano Sabatini2010-11-21

* Musepack SV8 supports "mono" files (though it still codes them as stereo),Kostya Shishkov2010-11-21
| | | | | | | | so extend decoder to output only one channel for it. This fixes issue 2368. Originally committed as revision 25790 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Use the new libavcore audio channel API.Stefano Sabatini2010-11-21
| | | | | | | This also allows to remove a linking dependency of libavfilter on libavcodec. Originally committed as revision 25789 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove declaration of function:Stefano Sabatini2010-11-21
| | | | | | | | const char *avcodec_get_channel_name(int channel_id) which was never implemented. Originally committed as revision 25788 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | | | | | PaletteControl. This also fixes playback of some files with ffplay (images were corrupted for a short time after a palette change). Originally committed as revision 25778 to svn://svn.ffmpeg.org/ffmpeg/trunk

* adpcm: Fix a comment in the trellis heap codeMartin Storsjö2010-11-20
| | | | | | This makes the wording consistent with how people usually talk about heaps. Originally committed as revision 25775 to svn://svn.ffmpeg.org/ffmpeg/trunk
* adpcm: Only increment heap_pos after finding a good enough sampleMartin Storsjö2010-11-19
| | | | | | | This increases the PSNR slightly (about 0.1 dB) for trellis sizes below 8, and gives equal PSNR for sizes above that. Originally committed as revision 25769 to svn://svn.ffmpeg.org/ffmpeg/trunk
* adpcm: Use a hash table to improve checking for duplicate samplesMartin Storsjö2010-11-19
| | | | | | | | | 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. Originally committed as revision 25768 to svn://svn.ffmpeg.org/ffmpeg/trunk

* adpcm: Replace any of the leaf nodes in the heapMartin Storsjö2010-11-12
| | | | | | | | | | | 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
* ReindentMartin Storsjö2010-11-12

* adpcm: Store the trellis nodes in a heap instead of a sorted arrayMartin Storsjö2010-11-12
| | | | | | | | | | 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.

* vorbisdec: Fix floor1 decodingGregory Maxwell2010-11-12
| | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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. Date: Fri, 5 Nov 2010 12:01:38 +0100 Originally committed as revision 25717 to svn://svn.ffmpeg.org/ffmpeg/trunk
