Michael Niedermayer	1c7b71a5bd	mpegvideo: Use the current_picture pts The picture slot can be recycled by select_input_picture and only current_picture is populated with the valid pts. Unbreak timestamps when in cbr mode. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Michael Niedermayer	66e959682c	avcodec/mpegvideo_enc: override bitrate tolerance when its value is too small Fixes Ticket3257 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	849d40dce6	avcodec/mpegvideo_enc: change some asserts to av_asserts Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
wm4	f6774f905f	mpegvideo: operate with pointers to AVFrames instead of whole structs The most interesting parts are initialization in ff_MPV_common_init() and uninitialization in ff_MPV_common_end(). ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL checks for Picture.f, because these functions can be called on uninitialized or partially initialized Pictures. NULL pointer checks are added to ff_thread_release_buffer() stub function. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	11 years ago
Michael Niedermayer	e92a78a409	avcodec/mpegvideo: make mc_mb_var_sum / mb_var_sum 64bit This avoids a hypothetical integer overflow with very high resolution video Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Vittorio Giovara	e0c16e4e32	mpegvideo: move mpegvideo formats-related defines to mpegutils.h	11 years ago
Michael Niedermayer	06a3185e38	avcodec/mpegvideo_enc: dont use direct mode for unaligned input Fixes Ticket3456 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Diego Biurrun	05563ccacc	dsputil: cosmetics: Lose camelCase on ff_cropTbl and ff_squareTbl names Also switch from "tbl" to "tab" name suffixes.	11 years ago
Diego Biurrun	9103185bd1	dsputil: Drop ff_check_alignment() function The function is supposed to confirm that the compiler provided enough alignment, but in practice it is only run in certain code paths and insufficient alignment problems are restricted to legacy compilers.	11 years ago
Michael Niedermayer	cbcfd7da4d	avcodec: support setting the chroma intra matrix Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Lukasz Marek	3f47e24cbe	lavc/mpegvideo: add missing const Signed-off-by: Lukasz Marek <lukasz.m.luki@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Janne Grunau	fb0c9d41d6	avutil: remove timer.h include from internal.h Added libavutil/timer.h include to all files with {START,STOP}_TIMER.	11 years ago
Martin Storsjö	cff480e49d	mpegvideo_enc: Don't call ff_h263dsp_init unconditionally This fixes builds with e.g. --disable-decoders --disable-encoders --enable-encoder=mjpeg. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Michael Niedermayer	d08dd32863	avcodec/mpegvideo_enc: disable direct mode in load_input_picture() for dimensions%16 != 0 We currently read a whole 16x16 block from the input at a few places Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	0117ba5594	avcodec/mpegvideo_enc: fix custom matrixes with jpeg Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	3ca7085ae2	avcodec: make "bitrate tolerance too small for bitrate" error more verbose Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	b8ff951ce0	avcodec/mpegvideo_enc: init chroma matrix for mjpeg Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	859d74040e	avcodec/mjpegenc: pass chroma quantization matrix through as well, not just luma Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	ebfe622bb1	mpegvideo: drop support for real (non-emulated) edges Several decoders disable those anyway and they are not measurably faster on x86. They might be somewhat faster on other platforms due to missing emu edge SIMD, but the gain is not large enough (and those decoders relevant enough) to justify the added complexity.	11 years ago
Anton Khirnov	aec25b1c46	mpegvideo: split the encoding-only parts of frame_start() into a separate function This introduces some code duplication. However, much of it should go away once the decoders stop using MpegEncContext.	11 years ago
Michael Niedermayer	46b06bd894	avcodec/mpegvideo_enc: implement frame skip score normalization Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	34fe125f4b	avcodec/mpegvideo_enc: fix frame skipping with intra only codecs Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Michael Niedermayer	535af2c222	avcodec/mpegvideo_enc/frame_end(): remove unused variable Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	b6e7834ac6	avcodec/mpegvideo_enc: fix linesizes in frame_end() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	24abd806ea	ljpegenc: deMpegEncContextize The encoder uses almost none of the mpegvideo infrastructure, only some fields from MpegEncContext. The FATE results change because now an all-zero quant matrix is written into the file. Since it is not used for anything for ljpeg, this should not be a problem.	11 years ago
Anton Khirnov	3360ad9955	mjpegenc: do not pass MpegEncContext to ff_mjpeg_encode_picture_trailer() This will allow deMpegEncContextizing the LJPEG encoder.	11 years ago
Anton Khirnov	058d5f2feb	mjpegenc: do not pass MpegEncContext to ff_mjpeg_encode_picture_header() This will allow deMpegEncContextizing the LJPEG encoder.	11 years ago

Anton Khirnov	bedf952bb8	mpegvideo: move setting encoding-only vars from common_defaults() to encode_defaults()	11 years ago
Diego Biurrun	8f8bc92365	Add missing #includes for INT64_MAX and INT64_C	11 years ago

Anton Khirnov	1c01b0253e	mpegvideo_enc: use the AVFrame API properly.	11 years ago
Ronald S. Bultje	458446acfa	lavc: Edge emulation with dst/src linesize Allow supporting files for which the image stride is smaller than the maximum block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.	11 years ago
Michael Niedermayer	2925571278	avcodec/mpegvideo_enc: Fix possibly exploitable security issue with -bf Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	aa24122989	lavc: deprecate FF_MAX_B_FRAMES We should not arbitrarily decide the maximum B-frame number for all encoders supported by Libav, each encoder should be able to set its own limits.	11 years ago
Anton Khirnov	8941971a8f	lavc: make error_rate a private option of mpegvideo encoders	11 years ago
Diego Biurrun	0338c39698	dsputil: Split off H.263 bits into their own H263DSPContext	11 years ago

Michael Niedermayer	ce55e667fa	avcodec/mpegvideo_enc: check that max_b_frames is not negative Fixes crash found by saste Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Ronald S. Bultje	93f305473f	lavc: Convert some remaining strides to ptrdiff_t	11 years ago
Diego Biurrun	b2bed9325d	cosmetics: Group .name and .long_name together in codec/format declarations	11 years ago
Ronald S. Bultje	face578d56	Rewrite emu_edge functions to have separate src/dst_stride arguments. This allows supporting files for which the image stride is smaller than the max. block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.	11 years ago
Ronald S. Bultje	c341f734e5	Convert multiplier for MV from int to ptrdiff_t. This prevents emulated_edge_mc from not undoing mvy*stride-related integer overflows. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	bb4b041df3	avcodec/mpegvideo_enc: check qmin/qmax Fixes Ticket2990 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Vittorio Giovara	22c879057e	mpegvideo_enc: drop outdated copy_picture_attributes() in favour of a modern av_frame_copy_props() Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
Stefano Sabatini	7eb6eb03d8	lavc/mpegvideo_enc: simplify timestamp checks in load_input_picture() Also improve error feedback while at it.	12 years ago
