Michael Niedermayer	f1e173049e	avcodec/jpeg2000: Remove CBLK limit This also reduces the amount of memory needed Fixes Ticket4672 The new code seems slightly faster as well, probably due to better cache usage Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Michael Niedermayer	5bf208f659	jpeg2000: Use separate fields for int and float codepaths Split stepsize and data into int and float variants. Eliminates a number of casts and simplifies spotting errors. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago

Michael Niedermayer	62d00aa22f	jpeg2000/j2k: merge j2k/jpeg2000.c/h Now only j2kdec / jpeg2000dec.c remain Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	8bedbb82ce	j2k/jpeg2000: split data pointer in int & float. This fixes a TODO item and unifies both decoders structures It also fixes undefined behavior due to aliasing violations I choose 2 fields instead of a union because mistakely using the wrong type with a union will lead to hard to debug "wrong output" while with 2 fields mistakely using the wrong type will crash with a null pointer derefernce which is much easier to debug Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	fe7136ef82	j2k/jpeg2000: split stepsize in float & int variables This is more clear and less prone to mistakes. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	f82e7330af	jpeg2000: merge mant type from j2k mant fits in 16bit Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
