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	83fd377c94	j2k/jpeg2000: merge float DWT and related code the float conditions are largely changed to check the DWT instead of the bitexact flag, which previously was wrong (DWT53 is always int) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
