* vc1: use the AVFrame API properly.Anton Khirnov2013-11-16

* lavc: Edge emulation with dst/src linesizeRonald S. Bultje2013-11-15
| | | | | | 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.
* hwaccel: Simplify ff_find_hwaccelLuca Barbato2013-11-10
| | | | It is always called by passing fields from an AVCodecContext.
* cosmetics: Group .name and .long_name together in codec/format declarationsDiego Biurrun2013-10-03

* vc1dec: Don't decode slices when the latest slice header failed to decodeMichael Niedermayer2013-09-22

* vc1dec: Make sure last_picture is initialized in vc1_decode_skip_blocksMartin Storsjö2013-09-22

* vc1dec: Undo mpegvideo initialization if unable to allocate tablesMartin Storsjö2013-09-22
| | | | | | | | | | Previously, s->context_initialized was left set to 1 if ff_vc1_decode_init_alloc_tables failed, skipping the initialization completely on the next decode call. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1dec: Fix leaks in ff_vc1_decode_init_alloc_tables on errorsMartin Storsjö2013-09-22

| | | | | Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* vc1: check the source buffer in vc1_mc functionsLuca Barbato2013-08-05
| | | | | Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* vdpau: remove old-style decodersRémi Denis-Courmont2013-08-05
| | | | Signed-off-by: Anton Khirnov <anton@khirnov.net>
* vc1dec: Fix mixed field/frame intensity compensationMichael Niedermayer2013-05-28
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1dec: Match addressing between compensation and MC in vc1_mc_4mv_chroma4Michael Niedermayer2013-05-28
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1dec: Handle top and bottom blocks in vc1_mc_4mv_chroma4() differently if ↵Michael Niedermayer2013-05-28
| | | | | | | | | | | needed Now it can use different references for those blocks and even use averaging. This fixes several chroma artifacts in several videos. Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1dec: Fix doxy for vc1_mc_4mv_chroma4()Michael Niedermayer2013-05-28
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1dec: Drop old use_ic code from vc1_b_mcMichael Niedermayer2013-05-28
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1: Use shuffled use_ic instead of equally shuffled mv_modeMichael Niedermayer2013-05-28
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1dec: Implement intensity compensation for vc1_interp_mc()Michael Niedermayer2013-05-28
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1dec: Redesign the intensity compensationMichael Niedermayer2013-05-28
| | | | | | | | | | | Use the intensity-compensated reference frame for subsequent fields/B-frames. Since we currently don't change the reference frame we have to maintain lookup tables for intensity compensation in the following dependent frames. Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1dec: Shuffle field MVs after decoding, not beforeMichael Niedermayer2013-05-28
| | | | | | | | | | | | This simplifies the code since copying MVs to the reference is not needed anymore (and maybe something about fixing artifacts). Also remove the unused mv_f_last. Fixes a small number of artifacts in black_screen_VC-1.mkv and several more artifacts in other videos. Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1dec: Add support for interlaced B-framesSebastian Sandberg2013-05-17

* vc1dec: Remove some now unused variablesMartin Storsjö2013-05-15
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1dec: Do not allow field_mode to change after the first headerMichael Niedermayer2013-05-15
| | | | | | | | This fixes out of array accesses. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1, mss2: Check for any negative return value from ff_vc1_parse_frame_headerMartin Storsjö2013-05-15
| | | | | | | | This is required if we return other error codes than explicitly -1, which so far has been the only other possible return value besides 0. Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1dec: Fix current ptr selection in vc1_mc_4mv_chroma()Michael Niedermayer2013-05-15
| | | | | | No sample tried shows a difference. Signed-off-by: Martin Storsjö <martin@martin.st>

* vc1dec: Fix tff == 0 handling in init_block_index()Michael Niedermayer2013-05-15
| | | | | | This fixes several files from VLC ticket 5887. Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1dec: Update destination pointers in context for fieldsMichael Niedermayer2013-05-15
| | | | | | | | | | | | | | | This replaces a large number of checks for the second field by fixing the pointers when they are setup. This should also fix I/BI field pictures. Changes checksums for vc1_sa10143, the file becomes slightly closer to what the reference decoder outputs. Based on "vc1dec: the second field is written wrong to the picture" by Sebastian Sandberg <sebastiand.sandberg@gmail.com>. Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1dec: Don't apply the loop filter on fieldsMartin Storsjö2013-05-14
| | | | | | | | Fixes read of uninitialized memory. Based on a patch by Michael Niedermayer. Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1dec: Don't attempt error concealment on field picturesMichael Niedermayer2013-05-14
| | | | | | This is not implemented and doesn't work. Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1dec: fieldtx is only valid for interlaced frame picturesSebastian Sandberg2013-05-14
| | | | | | The fieldtx_plane is not cleared for interlaced fields. Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1: Remove now unused variablesMartin Storsjö2013-04-20

* mpegvideo: Use hpeldsp instead of dsputil for half-pel functionsRonald S. Bultje2013-04-19
| | | | | | This also converts vc1, since that is mpegvideo-based. Signed-off-by: Martin Storsjö <martin@martin.st>
* avcodec: av_log_ask_for_sample() ---> avpriv_request_sample()Diego Biurrun2013-03-13

* lavc decoders: work with refcounted frames.Anton Khirnov2013-03-08
|
* Add missing error_resilience includes to files that use ERDiego Biurrun2013-03-07
|
* 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>
* Remove unnecessary dsputil.h #includesDiego Biurrun2013-02-26
|
* 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: Separate h264chromaDiego Biurrun2013-02-06
|
* vc1dec: use codec_id instead of codec_tag for VC1IMAGEVladimir Pantelic2013-02-06
| | | | | | | the rest of the code is using codec_id everywhere already Signed-off-by: Vladimir Pantelic <vladoman@gmail.com> Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>
* dsputil: remove one array dimension from avg_no_rnd_pixels_tab.Ronald S. Bultje2013-01-22

* 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>
* lavc: put FF_IDCT_{VP3,H264,CAVS,BINK,EA,WMV2} under FF_API_IDCT.Ronald S. Bultje2013-01-20
| | | | | | This allows us to get rid of them on the next major bump. All of the above are functionally irrelevant, and most of them are unused, except the vp3 one, which is used wrongly in the bfin arch optimizations.
* vc1dec: prevent a crash due missing pred_flag parameterVladimir Pantelic2013-01-11
| | | | | | | Handle pred_flag parameter not given to get_mvdata_interlaced() Signed-off-by: Vladimir Pantelic <vladoman@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* 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>
