| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally, a Laplace distribution is more typical of the residuals encoded, but for noisy input, it's both better and simpler to be safe and use a 1/d^2 distribution. Second hunk could use some renormalization but it has effectively little impact. Output size of ffvhuff on various 4:2:0 sequences: context=0,1/d: 851974 27226 1137281 context=0,1/d²: 619081 25069 1051500 context=0,1/d³: 501983 30454 1290561 context=0,lapl: 500650 31754 1304082 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* | avcodec/huffman/ff_huff_gen_len_table: support skiping stat=0 entriesMichael Niedermayer2014-06-09
| | | | | | | | | | | | | | This is probably not the simplest solution but as this is needed for a bugfix, simplification is left for later. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| | | | | | | | | | Almost all of the code is shared so there is little point in enabling one decoder/encoder without the other.
