Luca Barbato	e95c7a6185	mov: Preserve the metadata even when bit-exactness is requested Make sure to not write the custom `encoder` string in that case. Bug-Id: 845 CC: libav-stable@libav.org	10 years ago
Carl Eugen Hoyos	0f5b996531	lavc/j2kenc: Make jp2 output compatible with Kakadu. Fixes ticket #4689.	10 years ago
Michael Niedermayer	96e73fa649	avcodec/jpeg2000dec: Merge i_stepsize/2 decoder special case into dequant Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Tobias Rapp	2abdc6f477	fate: add some tests for ffv1 level 3 with 8/10/16 bps Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	b1fdf81c6e	avcodec/jpeg2000dwt: use 32x32->64 multiplies in the 9/7i DWT This significantly improves the quality when the integer 9/7 transform is used Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	6c7b1597c7	avcodec/jpeg2000: Move H band scaling from wavelet into quantization code This reduces the number of operations done and is equivalent except for rounding Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	1c495b0bf6	avcodec/jpeg2000: Move gainb handling into the quantization code 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>	10 years ago
Michael Niedermayer	3bcf61f495	avcodec/jpeg2000dwt: Fix value of F_LFTG_X and I_LFTG_X 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>	10 years ago
Michael Niedermayer	75651cd63f	avcodec/jpeg2000dwt: Fix order of operations in integer decomposition wavelets Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Michael Niedermayer	729108515d	avcodec/snowenc: set dia_size for the first pass of motion estimation too Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	58201c6e9e	avcodec/snowenc: correct fullpel search pattern No real difference in quality, its a bit slower for the same dia_size as more vectors are searched for the same dia_size Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	db6d0a5bd2	avcodec/snowenc: Fix used reference MV in fullpel iterative ME This very very slightly improves quality, no measurable speed change Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Michael Niedermayer	adfde9a646	avformat/avienc: Fix wrongly placed comment Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Kevin Wheatley	31c7c0e156	avformat/movenc: Move avid DNxHD padding to the correct spot Outputting DNxHD into .mov containers 'corrupts' following atoms until end of stsd ffmpeg and qtdump could not decode pasp/colr atoms in the files made by ffmpeg, when outputting DNxHD due to the incorrect padding placement. Now we add the padding in the correct place Tidy up FATE changes due to padding changes. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	7d24ccaf00	fate: mjpeg trellis test Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Kevin Wheatley	7fc33dca39	libavformat: DNxHD in .mov, switch unspecified color_range to mpeg Avid prefers mpeg range [16-235] by default this change brings ffmpeg into line with that. To obtain the old behaviour use '-color_range jpeg' on the command line prior to the ouput filename.

Carl Eugen Hoyos	3ea97767e4	Add an ARES atom to extradata when encoding avui. Allows playback with QuickTime and the original codec. Tested by Olaf Matthes, olaf matthes gmx de	10 years ago

Michael Niedermayer	42801505cd	tests: Add vsynth2 which uses the new reference.pnm 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>	10 years ago
Michael Niedermayer	ed49b142bb	tests: Rename vsynth2 to vsynth_lena This avoids confusion with a growing number of vsynth tests Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Reinhard Tartler	8895bf7b78	Replace lena.pnm The new reference.pnm is a freely licensed replacement. The photo has been taken by Reinhard Tartler on August 28 2014, and is licensed under the expat license as stated at http://www.jclark.com/xml/copying.txt	10 years ago

Christophe Gisquet	1086f09da3	dv: more precise weight table for 8x8 It is derived from the actual equations of the specs. In particular, it is closer to the inverse of what the encoder uses. fate tests accordingly updated. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Christophe Gisquet	6ee7681723	huffyuvenc: write last odd sample If width is odd, last sample wouldn't be written. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Christophe Gisquet	50a35f0d2e	fate: add test for old (v1) huffyuv and rgba Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Eric Lasota	8be23d424f	avcodec/roqvideo: use JPEG color range Signed-off-by: ejlasota <ejlasota@gmail.com> Also update fate test checksums Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Christophe Gisquet	e7fc5d53a0	huffyuv: change statistics initialization Normally, a Laplace distribution is more typical of the residuals encoded, but for noisy input, it's both better and simpler to be safe and use a 1/d^2 distribution. Second hunk could use some renormalization but it has effectively little impact.

Anton Khirnov	43e7f0797f	flvenc: only write the framerate tag based on avg_frame_rate Do not fall back on the codec timebase, since that can be anything for VFR video.	11 years ago
