* Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormatAnton Khirnov2012-10-08
|
* mpegvideo: set extended_data in ff_update_duplicate_context()Janne Grunau2012-10-03
| | | | | | AVFrame.extended_data has to reset to the AVFrame.data of the current thread context after copying the frame contents. Fixes crashes with frame-threading after 2bc0de38584.
* avcodec: Convert some commented-out printf/av_log instances to av_dlogDiego Biurrun2012-10-01
|
* avcodec: Drop some silly commented-out av_log() invocationsDiego Biurrun2012-10-01
|
* mpeg4: support frame parameter changes with frame-mtJanne Grunau2012-09-19
| | | | | | | Adds a flag context_reinit to MpegEncContext to relieable keep track of frame parameter changes which require a context reinitialization. This is required for broken inputs which change the frame size but error out before the context can be reinitialized.
* mpegvideo: check ff_find_unused_picture() return value for errorsJanne Grunau2012-09-19
|
* mpegvideo: release frame buffers before freeing themJanne Grunau2012-09-19
| | | | | Fixes triggering an assert in avcodec_default_release_buffer() introduced in 1b3439b30.
* mpegvideo: add reinit function for frame parameter changesJanne Grunau2012-09-19
| | | | | | This is mainly required for frame parameter changes during frame based multithreading but single threaded usage profits too from avoiding ff_MPV_common_end()/ff_MPV_common_init() cycles.
* mpegvideo: move frame size dependent memory management to separate functionsJanne Grunau2012-09-19
| | | | | This is a preparation for supporting frame size changes during frame-based multithreading.
* mpegvideo: set AVFrame fields to NULL after freeing the base memoryJanne Grunau2012-09-06
| | | | | | Prevents dangling pointers and makes access after free more obvious. Setting AVFrame.qscale_table to NULL is required for successfully allocating a previously freed Picture with ff_alloc_picture().
* mpegvideo: remove last_picture_ptr / h264 assert.Michael Niedermayer2012-09-04
| | | | | | | This assert is no longer true since h264 error concealment needs last_picture_ptr to be set. Signed-off-by: Martin Storsjö <martin@martin.st>

* x86: mpegvideo: more sensible names for optimization file and init functionDiego Biurrun2012-08-24
|
* mpegvideo: convert mpegvideo_common.h to a .c fileMans Rullgard2012-08-09
| | | | | | | | | | This file defines a single, huge function, MPV_motion(), which although being declared inline is not actually inlined by the compiler (for good reason). There is thus no sense in defining this function in a header file, resulting in multiple copies of it in the final library. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov2012-08-07

* Remove lowres video decodingMans Rullgard2012-04-21
| | | | | | | This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>
* MPV: set reference frame pointers to NULL when allocation of dummy pictures ↵Janne Grunau2012-03-23
| | | | fails
* MPV: always mark dummy frames as referenceJanne Grunau2012-03-16
| | | | | | | 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.
* mpeg4: report frame decoding completion at ff_MPV_frame_end().Ronald S. Bultje2012-03-16
| | | | | | | Prevents hangs on corrupt input. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* Replace AVFrame pointer casts by proper struct member accesses.Diego Biurrun2012-03-01

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

* dsputil: Add ff_ prefix to the dsputil*_init* 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.

* 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.

* 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

* w32threads: support for frame multithreadingSteven Walters2011-10-16

* 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
