* lavc/j2kenc: Make jp2 output compatible with Kakadu.Carl Eugen Hoyos2015-06-30
| | | | Fixes ticket #4689.
* avcodec/jpeg2000dec: Merge i_stepsize/2 decoder special case into dequantMichael Niedermayer2015-06-28
| | | | Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* avcodec/jpeg2000dwt: use 32x32->64 multiplies in the 9/7i DWTMichael Niedermayer2015-06-22
| | | | | | | This significantly improves the quality when the integer 9/7 transform is used Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* avcodec/jpeg2000: Move H band scaling from wavelet into quantization codeMichael Niedermayer2015-06-22
| | | | | | | This reduces the number of operations done and is equivalent except for rounding Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* avcodec/jpeg2000: Move gainb handling into the quantization codeMichael Niedermayer2015-06-22
| | | | | | | | thats how the specification defines it, this also improves numerical accuracy of the integer wavelet implementation. It otherwise should be equivalent, in case of overflows this can be reverted. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* avcodec/jpeg2000dwt: Fix value of F_LFTG_X and I_LFTG_XMichael Niedermayer2015-06-21
| | | | | | | | Even if the jpeg2000 spec uses a wrong value this does not make mathematics work this way, also this has been corrected in the 2004 version AFAIK Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* avcodec/jpeg2000dwt: Fix order of operations in integer decomposition waveletsMichael Niedermayer2015-06-20
| | | | Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* avcodec/j2kenc: Use JP2 format by defaultMichael Niedermayer2015-06-19
| | | | | | | | Without the JP2 fields its not possible to identify the colorspace Fixes Ticket538 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* avcodec/j2kenc: Properly flush the end of the truncated AC streamMichael Niedermayer2015-06-17
| | | | Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* avcodec/jpeg2000dwt: Support 9/7 singularity cases on the encoder sideMichael Niedermayer2015-06-17
| | | | Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* avcodec/jpeg2000dwt: More special cases to handle singularities in 9/7 decodeMichael Niedermayer2015-06-17
| | | | | | Fixes Ticket4634 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* avformat/avienc: Fix wrongly placed commentMichael Niedermayer2015-03-19
| | | | Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* tests: Add vsynth2 which uses the new reference.pnmMichael Niedermayer2014-12-02
| | | | | | | The file is already present in git and by using it we can perform more tests without the need of fate samples Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* tests: Rename vsynth2 to vsynth_lenaMichael Niedermayer2014-12-02
| | | | | | This avoids confusion with a growing number of vsynth tests Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* Set dwSuggestBufferSize to largest chunk size for every stream in avi.Carl Eugen Hoyos2014-05-19
| | | | | | | Fixes playback with WMP 9 for files with large (rawvideo) frames as explained in ticket #2145. Fixes ticket #2818.
* avcodec/jpeg2000dwt: merge rescaling with interleave in 9/7 int IDWTMichael Niedermayer2013-06-03
| | | | | | | Tha fate tests change because the edge mirroring was wrong before this commit Reviewed-by: Nicolas BERTRAND <nicoinattendu@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
