Vittorio Giovara	4bb1070c15	ffv1: Explicitly name the coder type FFv1 uses two types of coders, golomb and range with two different tables. This is exposed this in a rather convoluted way, for example mentioning to set coder type 1 while initializing the variable 'ac' to 2, because encoder does not use range coder with default table. Appropriate internal coder type values have been added and used in any check rather than using raw numbers. Initialization of avctx.coder_type in ffv1dec is removed because this field is encoder only. An unneeded validation check in the encoder is dropped too.

Michael Niedermayer	e4255eaf47	ffv1: split decoder and encoder This is not based on lucas work due to code divergence (its less work this way than trying to merge from a split based on 2 years outdated code) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Michael Niedermayer	54b2d317ed	ffv1: avoid checking a double for equality if 0.0 != 0.0 a out of array read would occur, equal checks with floating point may behave in such odd ways, though this is very unlikely in a real implementation of a compiler Fixes: CID718936 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
