2013-05-31j2k: restructure bitstream decodingMichael Niedermayer
This is based on jpeg2000 but differs because of problems with the design from jpeg2000 with currently supported files More files can be decoded after this commit, though they show heavy artifacts 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>
2013-05-29j2kdec: remove unused variablesMichael Niedermayer
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>

Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

2013-05-28j2kdec/jpeg2000dec: partially merge quantization codeMichael Niedermayer
The quantization code needs more work, not so much work merging but more work investigating what is correct. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
2013-05-28j2kdec: Try to fix 8bps output caseMichael Niedermayer
Ive no test samples for which this makes a difference but it matches the 16bit implementation. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
