2013-07-13jpeg2000: fix overflow in dequantizationMichael Niedermayer
Fixes decoding of file generated with: ffmpeg -f lavfi -i smptehdbars=hd720 -pix_fmt rgb48 /tmp/o.jp2 Reviewed-by: Nicolas BERTRAND <nicoinattendu@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

2013-05-30jpeg2000/j2k: merge j2k/jpeg2000.c/hMichael Niedermayer
Now only j2kdec / jpeg2000dec.c remain Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
2013-05-30j2k/jpeg2000: split data pointer in int & float.Michael Niedermayer
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>
2013-05-29j2k/jpeg2000: merge float DWT and related codeMichael Niedermayer
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>
