Michael Niedermayer	7ca0cd5831	avcodec/jpeg2000dec: iterate in tile sample space for CPRL & RPCL Thats what the spec says should be done aka iterate in the wrong space and use special cases to patch that up. It sometimes can result in different order 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	05ef6324d1	avcodec/jpeg2000dec: Add 5/3 de-quantization special case for the lossless case This avoids a multiplication and 64bits 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
