[Ffmpeg-devel] Trellis Quantization Applied To (A)DPCM

[Mike Melanson]

Hi,
	I see that Loren took Michael's suggestion seriously and applied 
Trellis quantization to the ADPCM encoder. This reminds me of 
discussions on MPlayer-devel about optimizing ADPCM decoding with SIMD 
instructions. :)

	So, can this be applied to, e.g., Creative YUV? I had wanted to write 
an encoder for that at one point but I sort of got stuck wondering about 
an optimal (quality-wise) method for creating the delta tables.
