Michael Niedermayer	9841024402	avcodec/jpeg2000dwt: More special cases to handle singularities in 9/7 decode Fixes Ticket4634 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	1125c71fd7	avcodec/jpeg2000dwt: assert that mod == 0 for encoding We are missing the handling of some special cases for this. These cases should be unused and there should be no reason to ever use them unless some spec dictates their use Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Michael Niedermayer	197e219c92	jpeg2000dwt: add float based 9/7 dwt Untested as theres no code yet using it in the encoder. Code based on mixed float/int dwt Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	cf05fe8a7e	jpeg2000dwt: remove floats from mixed float/int 9/7 dwt This should fix some fate failures Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
