Michael Niedermayer	50b77e364f	avcodec/jpeg2000dec: iterate over positions with the special cases from jpeg2000 The order in j2k is not the simple and logic one Fixes Ticket4670 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	6c4a2f11dd	avcodec/jpeg2000dec: Add coords to Jpeg2000Tile These will be needed in subsequent commits Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Michael Niedermayer	ffa1de8a3b	avcodec/jpeg2000dec: Use 32x32->64bit for 9/7i dequantization Like the 5/3 case this is needed to avoid overflows and similarly for 16bpp output pure 32bit operations are insufficient if high quality is wanted Note, this code-path is only used in bitexact mode, so this should not affect the speed of any real use-case Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Michael Niedermayer	8ff09e9098	avcodec/jpeg2000dec: Use 32x32->64bit for 5/3 dequantization This fixes overflows, using fewer bits would impact high bit depth quality Fixes Ticket4654 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
