* Replace AVFrame pointer casts by proper struct member accesses.Diego Biurrun2012-03-01

* mpegvideo: Add ff_ prefix to nonstatic functionsMartin Storsjö2012-02-15

* vlc/rl: Add ff_ prefix to the nonstatic symbolsMartin Storsjö2012-02-15
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* Remove Sun medialib glue code.Diego Biurrun2012-02-08
| | | | | It is obscure, most likely unused and not bit-exact compared to libavcodec due to a different IDCT transform algorithm.
* mpegvideo: fix invalid memory access for small video dimensionsJohn Brooks2012-01-21
| | | | | | | | | | 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>
* mpegvideo: claim ownership of referenced picturesJanne Grunau2012-01-10
| | | | | | | | | 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.
* cosmetics: drop some pointless parenthesesDiego Biurrun2012-01-07
|
* mpegenc: use avctx->slices as number of slicesJanne Grunau2012-01-02
| | | | | | 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.
* mpegvideo.c: K&R formatting and cosmetics.Konstantin Todorov2011-12-25

* avcodec: deprecate AVFrame.ageMans Rullgard2011-12-18
| | | | | | | | 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>

* avcodec: change number of plane pointers from 4 to 8 at next major bump.Justin Ruggles2011-12-02
| | | | | | 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.
* avcodec: move some AVCodecContext fields to an internal struct.Justin Ruggles2011-11-19
| | | | | | | | 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.
* hwaccel: OS X Video Decoder Acceleration (VDA) support.Sebastien Zwickert2011-11-14
| | | | Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* mpeg12: move closed_gop from MpegEncContext to Mpeg1ContextAnton Khirnov2011-10-23
| | | | It's MPEG-1/2 specific.
* lavc: use avpriv_ prefix for ff_toupper4.Anton Khirnov2011-10-20
| | | | It's used in lavf.
* lavc: rename ff_find_start_code to avpriv_mpv_find_start_codeAnton Khirnov2011-10-20
| | | | It's used in lavf.
* w32threads: support for frame multithreadingSteven Walters2011-10-16
| | | | | | | | 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>
* mpegvideo: set correct offset for edge emulation buffer.Ronald S. Bultje2011-10-05
| | | | | 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.
* mpegvideo: fix position of bottom edge.Ronald S. Bultje2011-10-05
| | | | | It was wrong in colorspaces where horizontal and vertical chroma subsampling are not the same, e.g. 422.
* lavc: replace some deprecated FF_*_TYPE with AV_PICTURE_TYPE_*Anton Khirnov2011-09-21
|
* Fix assert() calls that need updates after FF_COMMON_FRAME macro elimination.Diego Biurrun2011-09-21
| | | | This fixes build failures with -DDEBUG in CPPFLAGS.

* mpegvideo: initialise DSPContext in ff_dct_common_init()Mans Rullgard2011-07-27
| | | | | | | 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>
* mpegvideo: fix invalid picture unreferencing.Ronald S. Bultje2011-07-20
| | | | | | | | | | | 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.
* Eliminate FF_COMMON_FRAME macro.Diego Biurrun2011-07-11
| | | | | 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.
* mpeg1video: don't abort if thread_count is too high.Frank Barchard2011-07-09
| | | | | | Instead, just decrease it to a valid value and use that. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* H.264: fix overreads of qscale_tableJason Garrett-Glaser2011-07-04
| | | | filter_mb_fast assumed that qscale_table was padded like many of the other tables.
* 4:4:4 H.264 decoding supportJason Garrett-Glaser2011-06-13
| | | | Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.
* Roll back 4:4:4 H.264 for nowJason Garrett-Glaser2011-06-13
| | | | Needs some ARM/PPC asm modifications.
* 4:4:4 H.264 decoding supportJason Garrett-Glaser2011-06-13

* mpegvideoenc: fix multislice fate tests with threading disabled.Ronald S. Bultje2011-06-03
| | | | | The MPEG encoding code assumes that n_threads == n_slices, and thus it should use n_slices even if threading itself is disabled.

* Remove h263_msmpeg4 from MpegEncContext.Alex Converse2011-05-25
| | | | It was long ago superseded by msmpeg4_version.
* mpegvideo: make FF_DEBUG_DCT_COEFF output coeffs via av_log() instead of ↵Michael Niedermayer2011-05-12
| | | | | | | | | 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>

* Merge libavcore into libavutilReinhard Tartler2011-02-15
| | | | | | | | | | | | It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.
