Michael Niedermayer	84a6bc2357	jpeg2000: tag_tree_size: replace check by assert This function is never called with values large enough for the error condition to occur Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	8bedbb82ce	j2k/jpeg2000: split data pointer in int & float. 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>	12 years ago

Martin Storsjö	86113667c0	arm: Include hpeldsp_neon.o if h264qpel is enabled A few of the h264qpel neon functions are shared with other hpeldsp functions in this file. This fixes standalone compilation of the h264 decoder on arm. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	efb7968cfe	arm: Don't unconditionally build dsputil files Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	36a7df8cf1	arm: Only build the FFT init files if FFT is enabled This fixes build errors in cases where FFT is disabled. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Reimar Döffinger	dccaad3bcd	wamenc: handle failure to encode. This is necessary since the switch to floating point input means there is no longer sufficient input data validation. There is a good chance that other encoders are affected by similar issues. This problem can be triggered by trying to encode extremely large values and probably also with Inf and possibly also NaNs. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	12 years ago
Luca Barbato	701966730c	vmd: drop incomplete chunks and spurious samples Odd chunk size makes no sense for stereo and incomplete chunks are not supported. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	12 years ago
Michael Niedermayer	ac025d6eca	j2kdec: remove unused variables Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	c2625c26c5	mpegvideo: implement ff_put_h264_chroma_mc1 & ff_avg_h264_chroma_mc2 These are needed for lowres 3 This may fix Ticket2538 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Luca Barbato	676da248ca	vmd: refactor the inner decode loop Simplify a little, assume empty frames are acceptable and do not pointlessly reinit the bytestream2 contexts using possibly wrong size values. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	12 years ago
Luca Barbato	c8f3cb9119	vmd: return meaningful errors CC: libav-stable@libav.org	12 years ago
Luca Barbato	91a6944e56	vmd: use the PALETTE_COUNT constant uniformly While at it drop useless parentheses.	12 years ago
Michael Niedermayer	83fd377c94	j2k/jpeg2000: merge float DWT and related code 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>	12 years ago

Michael Niedermayer	c37d735c1c	jpeg2000dec: mct_decode: remove unused return Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	fe7136ef82	j2k/jpeg2000: split stepsize in float & int variables This is more clear and less prone to mistakes. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	f7129ab928	j2k/jpeg2000: fix typo in lut_gain index no testcase Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Janne Grunau	bf20cdbd86	mpeg12: skip frames consistently The decoder did not start predicted frames with missing references but called the end of frame handling on them anyway. This caused an assertion in the VA API HW accelorator since it tried to render a picture with uninitialized buffers.	12 years ago
Michael Niedermayer	32475f56f3	j2kdec/jpeg2000dec: partially merge quantization code 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>	12 years ago
Michael Niedermayer	f0a2c8285a	j2kdec: Try to fix 8bps output case Ive no test samples for which this makes a difference but it matches the 16bit implementation. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	89806691b1	wavpack: check that all the channels were coded.	12 years ago
Anton Khirnov	eae1b8451a	wavpack: check that there aren't too many blocks per packet	12 years ago
Anton Khirnov	7d039e70a5	wavpack: extract channel information from the bitstream This way we don't require the caller to parse the block header. It also allows the channel configuration to change mid-stream.	12 years ago
Anton Khirnov	78f75b6fa4	wavpack: extract sample rate from the bitstream This way we don't require the caller to parse the block header. It also allows the sample rate to change mid-stream.	12 years ago
Kostya Shishkov	2cf5d29110	indeo4: reuse context block VLC for band instead of defaulting Currently if no custom block VLC is specified for band, a default block VLC will be used, while the global block VLC stored in the context should be used instead. This fixes decoding of one sample I have.	12 years ago
Kostya Shishkov	6647aa0426	indeo4: add missing Haar and slanted transforms That involves fixing INV_HAAR4() macro and changing it to work with different input and output like INV_HAAR8() instead of in-place transform.	12 years ago
Kostya Shishkov	3b03d7e251	dxtory v2 support	12 years ago
Michael Niedermayer	728214992e	vc1dec: Remove interlaced warning Also add a note about the feature in the changelog. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	d8b9dbe776	vc1dec: Fix mixed field/frame intensity compensation Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	17410faa22	vc1dec: Match addressing between compensation and MC in vc1_mc_4mv_chroma4 Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	1be175f929	vc1dec: Handle top and bottom blocks in vc1_mc_4mv_chroma4() differently if needed Now it can use different references for those blocks and even use averaging. This fixes several chroma artifacts in several videos. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	c69765a2cc	vc1dec: Fix doxy for vc1_mc_4mv_chroma4() Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	b412f705b5	vc1dec: Drop old use_ic code from vc1_b_mc Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	5053a9a1ff	vc1: Use shuffled use_ic instead of equally shuffled mv_mode Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	3ced06f283	vc1dec: Implement intensity compensation for vc1_interp_mc() Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	28243b0d35	vc1dec: Redesign the intensity compensation Use the intensity-compensated reference frame for subsequent fields/B-frames. Since we currently don't change the reference frame we have to maintain lookup tables for intensity compensation in the following dependent frames. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	93b1281264	vc1dec: Shuffle field MVs after decoding, not before This simplifies the code since copying MVs to the reference is not needed anymore (and maybe something about fixing artifacts). Also remove the unused mv_f_last. Fixes a small number of artifacts in black_screen_VC-1.mkv and several more artifacts in other videos. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
