* lavc: Split out ff_hwaccel_pixfmt_list_420[] over individual codecsRonald S. Bultje2013-03-06
| | | | | | | | | Not all hwaccels implement all codecs, so using one single list for multiple such codecs means some codecs will be represented in the list, even though they don't actually handle that codec. Copying specific lists in each codec fixes that. Signed-off-by: Martin Storsjö <martin@martin.st>
* mpegvideo: split ff_draw_horiz_band().Anton Khirnov2013-02-15
| | | | Split out dependency on MpegEncContext.
* error_resilience: decouple ER from MpegEncContextAnton Khirnov2013-02-15

* dsputil: Move ff_block_permute to mpegvideo_encDiego Biurrun2013-02-07

* mpegvideo: remove an unused function parameterAnton Khirnov2013-02-06

* mpegvideo: initialize dummy reference frames.Anton Khirnov2013-02-06
| | | | | | | Do not rely on get_buffer initializing them. Changes yadif tests (off by one in one border pixel), because yadif reads from those uninitialized lines.
* hwaccel: do not offer unsupported pixel formatsRémi Denis-Courmont2013-01-27

* Drop DCTELEM typedefDiego Biurrun2013-01-22
| | | | | | It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* mpegvideo: fix loop condition in draw_line()Xi Wang2013-01-19
| | | | | | | | | | | The loop condition `x = ex' is incorrect. It should be `x <= ex'. This bug was introduced in commit c65dfac4 "mpegvideo.c: K&R formatting and cosmetics." CC:libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* mpegvideo: initialize videodsp with correct pixel depthJanne Grunau2012-12-26
| | | | | Fixes decoding of 9/10 bit per pixel h264 videos as reported in https://bugzilla.libav.org/show_bug.cgi?id=404 .
* lavc: introduce VideoDSPContextRonald S. Bultje2012-12-20
| | | | | | | | Move some functions from dsputil. The idea is that videodsp contains functions that are useful for a large and varied set of video decoders. Currently, it contains emulated_edge_mc() and prefetch(). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* mpegvideo: increase edge_emu_buffer size for VC1Janne Grunau2012-12-19
| | | | | | | | | The VC1 decoder uses edge_emu_buffer simultaneously for luma and chroma and needs more space. That was not a problem before f1d8763a02b5fce since the size for edge_emu_buffer was always calculated with 2 byte per pixel since the linesize was not known. Fixes occasionally fate errors in vc1_sa10143.
* mpegvideo: allocate scratch buffers after linesize is knownJanne Grunau2012-12-18
| | | | | | | | | | | Since we can't know which stride a custom get_buffer() implementation is going to use we have to allocate this scratch buffers after the linesize is known. It was pretty safe for 8 bit per pixel pixel formats since we always allocated memory for up to 16 bits per pixel. It broke hoever with cmdutis.c's alloc_buffer() and high pixel bit depth since it allocated larger edges than mpegvideo expected. Fixes fuzzed sample nasa-8s2.ts_s244342.
* mpegvideo: treat delayed pictures as usedJanne Grunau2012-12-13
| | | | | | This requires to move the avcodec_default_free_buffers() call to ff_MPV_common_end() since otherwise delayed pictures would get freed during a size change.
* cosmetics: Fix dropable --> droppable typoDiego Biurrun2012-12-09
|
* h264: set Picture.owner2 to the current threadJanne Grunau2012-11-27
| | | | | | | | This does not seem to have an effect currently. Fate-h264 passes with THREADS=1..16 and both threading types as before. It fixes however a segfault during error resilience with my adaptive-frame-mt patchset. A picture in use during error resilience gets realloced in another thread in the fuzzed sample sample_varPAR.avi_s226019.
* pixdesc: add av_pix_fmt_get_chroma_sub_sampleLuca Barbato2012-11-13
| | | | Deprecate avcodec_get_chroma_sub_sample.

* avcodec: Remove broken MMI optimizationsDiego Biurrun2012-10-12
| | | | The code fails to compile and is broken beyond repair.

* 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>

* 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>

* MPV: set reference frame pointers to NULL when allocation of dummy pictures ↵Janne Grunau2012-03-23

* 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

* 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.
