Mans Rullgard	2bcbd98459	Remove lowres video decoding This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Janne Grunau	5ab506a5c8	MPV: set reference frame pointers to NULL when allocation of dummy pictures fails	13 years ago
Janne Grunau	7b60799aa8	MPV: always mark dummy frames as reference If the dummy frame are not created from a reference frame they could be deleted untimely resulting in multithreaded decoder waiting on the current frame to finish. Noticed by Ronald S. Bultje in the RV34 decoder with a broken file.	13 years ago
Ronald S. Bultje	c6ccb96bc9	mpeg4: report frame decoding completion at ff_MPV_frame_end(). Prevents hangs on corrupt input. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Diego Biurrun	47c0ac96aa	Replace AVFrame pointer casts by proper struct member accesses.	13 years ago
Martin Storsjö	efd29844eb	mpegvideo: Add ff_ prefix to nonstatic functions Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	9cf0841ef3	dsputil: Add ff_ prefix to the dsputil_init functions Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	e96b4a53df	vlc/rl: Add ff_ prefix to the nonstatic symbols Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Diego Biurrun	0144fe6995	Remove Sun medialib glue code. It is obscure, most likely unused and not bit-exact compared to libavcodec due to a different IDCT transform algorithm.	13 years ago
John Brooks	9b6aafba6c	mpegvideo: fix invalid memory access for small video dimensions When either video dimension is only one macroblock, subtractions based on v_edge_pos and the macroblock size may be negative. In that situation, an unsigned comparison isn't sufficent to test for MV overruns, because a limit of (unsigned)-1 will let any other value pass. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Janne Grunau	3ab7700018	mpegvideo: claim ownership of referenced pictures Under certain conditions pictures could be released before they were returned with frame-threading. Broken mv computation in the upcoming rv34 frame-threading patch was caused by this. To prevent contexts from running out of available pictures the loop releasing "unused" pictures has to be run for B frames too.	13 years ago
Diego Biurrun	3dc99a18d4	cosmetics: drop some pointless parentheses	13 years ago
Janne Grunau	881a5e047d	mpegenc: use avctx->slices as number of slices Adds a new member to MpegEncContext to hold the number of used slice contexts. Fixes segfaults with '-threads 17 -thread_type slice' and fate-vsynth{1,2}-mpeg{2,4}thread{,_ilace} with --disable-pthreads.	13 years ago
Konstantin Todorov	c65dfac466	mpegvideo.c: K&R formatting and cosmetics. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Mans Rullgard	8400b126ac	avcodec: deprecate AVFrame.age This was intended as an optimisation for skipped blocks in MPEG2 P-frames and never used elsewhere. Removing this "optimisation" speeds up MPEG2 decoding by 1-2% (ARM Cortex-A9). Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Andrey Utkin	4f820131fa	mpegvideo: remove abort() in ff_find_unused_picture() Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	13 years ago
Diego Biurrun	58c42af722	doxygen: misc consistency, spelling and wording fixes	13 years ago
Dustin Brody	5b22d6e132	lavc: convert error_recognition to err_recognition. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Diego Biurrun	ee41963f19	cosmetics: drop some completely pointless parentheses	13 years ago
Konstantin Todorov	4d9ec050a2	Code cleanup - mpegvideo.c - 500-1000line Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Konstantin Todorov	363114e813	mpegvideo.c: code cleanup - first 500 lines. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Justin Ruggles	560f773c7d	avcodec: change number of plane pointers from 4 to 8 at next major bump. Add AV_NUM_DATA_POINTERS to simplify the bump transition. This will allow for supporting more planar audio channels without having to allocate separate pointer arrays.	13 years ago
Justin Ruggles	f3a29b750a	avcodec: move some AVCodecContext fields to an internal struct. A new field, AVCodecContext.internal is used to hold a new struct AVCodecInternal, which has private fields that are not codec-specific and are used by general libavcodec functions. Moved internal_buffer, internal_buffer_count, and is_copy.	13 years ago
Sebastien Zwickert	ac3dbb4d58	hwaccel: OS X Video Decoder Acceleration (VDA) support. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	13 years ago
Anton Khirnov	3fc0830432	mpeg12: move closed_gop from MpegEncContext to Mpeg1Context It's MPEG-1/2 specific.	13 years ago
Anton Khirnov	0842d58998	lavc: use avpriv_ prefix for ff_toupper4. It's used in lavf.	13 years ago
Anton Khirnov	773375c3d0	lavc: rename ff_find_start_code to avpriv_mpv_find_start_code It's used in lavf.	13 years ago
Steven Walters	27237d524e	w32threads: support for frame multithreading Replace our incomplete w32threads implementation with x264's pthreads w32threads wrapper. Relicensed to LGPL with kind permission by Pegasys Inc. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Ronald S. Bultje	330deb7592	mpegvideo: set correct offset for edge emulation buffer. Using the old code, half of it was unused and the other half was too small for e.g. >8bpp interlaced data, causing random buffer overruns.	13 years ago
Ronald S. Bultje	0884dd5a1b	mpegvideo: fix position of bottom edge. It was wrong in colorspaces where horizontal and vertical chroma subsampling are not the same, e.g. 422.	13 years ago
Anton Khirnov	e5b29c1f6b	lavc: replace some deprecated FF__TYPE with AV_PICTURE_TYPE_	13 years ago
Diego Biurrun	95a06eb4d5	Fix assert() calls that need updates after FF_COMMON_FRAME macro elimination. This fixes build failures with -DDEBUG in CPPFLAGS.	13 years ago
Alberto Delmás	45ecda8554	Windows Media Image decoder (WMVP/WVP2) Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Mans Rullgard	c3027b4d2f	mpegvideo: initialise DSPContext in ff_dct_common_init() The functions and tables initialised in this function rely on an initialised DSPContext. Make sure they always have one. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Ronald S. Bultje	80469eafb7	mpegvideo: fix invalid picture unreferencing. Mpegvideo would free frames as soon as they're not the next or prev picture. This is fine for a single-threading model, but fails miserably in a system where pictures can be referenced (as e.g. last/prev pic) in other threads. Keeping track of ownership of pictures keeps image references (e.g. motion vectors, or the reference of a motion vector) alive as long as the picture data itself is alive. This also happens to fix make THREADS=[3-16] fate-vsynth[12]-error.	14 years ago
Diego Biurrun	657ccb5ac7	Eliminate FF_COMMON_FRAME macro. FF_COMMON_FRAME holds the contents of the AVFrame structure and is also copied to struct Picture. Replace by an embedded AVFrame structure in struct Picture.	14 years ago
Frank Barchard	f98c9fb27d	mpeg1video: don't abort if thread_count is too high. Instead, just decrease it to a valid value and use that. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Jason Garrett-Glaser	5029a40633	H.264: fix overreads of qscale_table filter_mb_fast assumed that qscale_table was padded like many of the other tables.	14 years ago
Jason Garrett-Glaser	c90b94424c	4:4:4 H.264 decoding support Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.	14 years ago
Jason Garrett-Glaser	504811baea	Roll back 4:4:4 H.264 for now Needs some ARM/PPC asm modifications.	14 years ago
Jason Garrett-Glaser	c9c493872c	4:4:4 H.264 decoding support Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.	14 years ago
Ronald S. Bultje	83a8b3002f	mpegvideoenc: fix multislice fate tests with threading disabled. The MPEG encoding code assumes that n_threads == n_slices, and thus it should use n_slices even if threading itself is disabled.	14 years ago
Alexander Strange	6a9c859444	H264/MPEG frame-level multi-threading. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Alex Converse	8c51620f21	Remove h263_msmpeg4 from MpegEncContext. It was long ago superseded by msmpeg4_version.	14 years ago
Michael Niedermayer	c4fb3b0327	mpegvideo: make FF_DEBUG_DCT_COEFF output coeffs via av_log() instead of just via AVFrame. This allows the values to be used without changing C code and is closer to how the other DEBUG flags work. Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Anatoly Nenashev	b44c8ad280	Fix crash of interlaced MPEG2 decoding Problem description, preliminary review discussion at http://thread.gmane.org/gmane.comp.video.ffmpeg.devel/127731	14 years ago
