Davinder Singh	4116b2b136	avcodec/mjpegenc: cosmetic changes Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	7 years ago
Davinder Singh	1939b90306	avcodec/mjpegenc: disable unused code with AMV disable unused amv_encode_picture() when AMV encoder is not configured. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	7 years ago
James Almer	2cb656ad11	avcodec/mjpegenc: move ff_mjpeg_encode_picture_frame to mjpegenc_common Fixes compilation of ljpeg encoder if mjpeg and amv encoders are disabled	8 years ago
Rostislav Pehlivanov	45eeb1f785	mjpegenc: enable optimal huffman coding by default As it gives excellent encoding gains at an insignificant speed increase and passes fate without problems, it should now be safe to enable by default. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	8 years ago
Michael Niedermayer	3e1507a954	avcodec/mjpegenc: Bypass the 2 pass encoding when optimal tables are not requested This limits the bugs, speedloss and extra memory allocation to the case when optimal tables are needed. Fixes regressions with slice multi-threading Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago
Michael Niedermayer	f57665b318	avcodec/mjpegenc: Revert some differences in ff_mjpeg_encode_mb() relative to pre optimal huffman The changes are not needed anymore and the return code was never used Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago
Michael Niedermayer	daccbe81a2	avcodec/mjpegenc: Drop i_tex misuse, set itex/header bits correctly, fix 2pass encoding Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago
Michael Niedermayer	e10bd12c25	avcodec/mjpegenc: Remove non functional huffman reallocation and error handling If this is wanted iam not against it but it must be designed to work with all cases like slice threads, and a single growing buffer does not work very well with slices. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago
Rostislav Pehlivanov	a70f0927ea	mjpegenc: use s->avctx as a context for av_log rather than NULL Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	8 years ago
Rostislav Pehlivanov	d164ef6589	mjpegenc_common: add missing ff_ prefix to init_uni_ac_vlc Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	8 years ago

Diego Biurrun	0f40c90984	Drop pointless assert.h #includes	9 years ago
Derek Buitenhuis	c4ef6c883b	mjpegenc: Remove duplicate initializer This was causing c99conv to crash. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	9 years ago
Vittorio Giovara	2862b63783	lavc: Move prediction_method to codec private options This options is only used by huffyuv, ffvhuv, jpegls, mjpeg, mpegvideoenc, png, utvideo. It is a very codec-specific options, so deprecate the global variant. Set proper limits to the maximum allowed values, and update utvideoenc tests to use the new option name. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Ronald S. Bultje	2fb593dcb9	Put remaining pieces of CODEC_FLAG_EMU_EDGE under FF_API_EMU_EDGE. The amv one probably looks suspicious, but since it's an intra-only codec, I couldn't possibly imagine what it would use the edge for, and the vsynth fate result doesn't change, so it's probably OK.	9 years ago

Michael Niedermayer	d41a4a765b	avcodec/mjpegenc: allow encoding amv with height % 16 != 0 when strict -1 is set This should make it simpler for users to test if such videos work Suggested-by: carl Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Reimar Döffinger	6d695d7acc	Fix nonsense non-mod16 AMV flipping code. It is obviously nonsense since it produces wrong results or even crashes (crashes should be encode-only though). Fixes trac issue #1092. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	181b2c3724	avcodec/mjpegenc: disallow encoding amv with height%16!=0 I do not know on which side to place the padding to encode with 16x16 MBs If someone knows or has a known to be correct sample, please contact me Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Michael Niedermayer	a26e9c1040	avcodec/mjpegenc: Use av_frame_clone() instead of av_frame_ref() This avoids the need for double error checking Fixes CID1163843 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
