[FFmpeg-devel] [PATCH] trellis quantization support for adpcm_swf

[Benjamin Larsson]

This patch adds trellis quantization for the flv/swf adpcm variant. And
it closes issue 79 in the issue tracker.

With a random test file I get these benchmarks:

without trellis:
stddev: 87.04 PSNR:57.52

trellis level 1:
stddev: 81.96 PSNR:58.05

trellis level 5:
stddev: 70.96 PSNR:59.30
