* vp78: Align the intra4x4_pred_mode_top array within VP8MacroblockMartin Storsjö2014-04-14
| | | | | | | | This array is written using AV_WN32A, assuming alignment. This hopefully fixes the failing vp7 fate test on sparc. Signed-off-by: Martin Storsjö <martin@martin.st>
* On2 VP7 decoderPeter Ross2014-04-04
| | | | | | | | | Further performance improvements and security fixes by Vittorio Giovara, Luca Barbato and Diego Biurrun. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org> Signed-off-by: Diego Biurrun <diego@biurrun.de>

* vp8: use a fixed-size edge emu bufferAnton Khirnov2014-02-04
| | | | | | The reason is the same as for e588615d938f8581f0d6f3771662d08cadfc00de Based on a patch by Ronald S. Bultje <rsbultje@gmail.com>
* Add a WebP decoderJustin Ruggles2013-09-18

* vp56data: Move all shared enum/struct declarations to common headerDiego Biurrun2013-08-15

* w32pthreads: move from lavc to compat/Anton Khirnov2013-05-24
| | | | It will be used in other places than lavc.
* lavc decoders: work with refcounted frames.Anton Khirnov2013-03-08

* 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: 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>
* Give all anonymously typedeffed structs in headers a nameDiego Biurrun2012-10-06
| | | | Anonymous structs cannot be forward declared and have no benefit.
* vp8: pack struct VP8ThreadData more efficientlyMans Rullgard2012-08-02
| | | | | | | | Reordering the members in this struct reduces the holes required to maintain alignment. With this order, the only remaining, and unavoidable, hole is 3 bytes following left_nnz. Signed-off-by: Mans Rullgard <mans@mansr.com>
* vp8: Enclose pthread function calls in ifdefsMartin Storsjö2012-07-15
| | | | | | This fixes building with threads disabled. Signed-off-by: Martin Storsjö <martin@martin.st>
* vp8: Include the thread headers before using the pthread typesMartin Storsjö2012-07-14
| | | | | | | This was unnoticed on linux, since stdlib.h apparently includes files declaring the pthread_mutex_t and pthread_cond_t types. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* vp8: implement sliced threadingDaniel Kang2012-07-14
| | | | | | | | | | | | Testing gives 25-30% gain on HD clips with two threads and up to 50% gain with eight threads. Sliced threading uses more memory than single or frame threading. Frame threading and single threading keep the previous memory layout. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* vp8: move data from VP8Context->VP8MacroblockDaniel Kang2012-07-14
| | | | | | In preparation for sliced threading. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* vp8: fix up handling of segmentation_maps in reference frames.Ronald S. Bultje2011-10-21
| | | | | | | | | Associate segmentation_map[] with reference frame, rather than decoding instance. This fixes cases where the map would be free()'ed on e.g. a size change in one thread, whereas the other thread was still accessing it. Also, it fixes cases where threads overwrite data that is still being referenced by the previous thread, who thinks that it's part of the frame previously decoded by the next thread.
* multiple inclusion guard cleanupDiego Biurrun2011-05-21
| | | | | Add missing multiple inclusion guards; clean up #endif comments; add missing library prefixes; keep guard names consistent.
* vp8: frame-multithreading.Ronald S. Bultje2011-05-02

* VP8: optimize VP8Context struct orderingJason Garrett-Glaser2011-03-12
| | | | | Shaves at least 3KB off code size on x86, should improve cache utilization. This would probably be useful to do for other decoders/encoders as well.
* VP8: token probs doesn't need paddingJason Garrett-Glaser2011-03-12
| | | | | prob[0] is the only prob array ever accessed, so prob[1] can serve as padding for prob[0].
* VP8: split out declarations to new headerJason Garrett-Glaser2011-02-17
