* 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>
* vp8: drop support for real (non-emulated) edgesAnton Khirnov2014-01-09
| | | | | | They are not measurably faster on x86, they might be somewhat faster on other platforms due to missing emu edge SIMD, but the gain is not large enough to justify the added complexity.
* 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.

* 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>

* 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 block coeff arithcoder on stack.Ronald S. Bultje2012-05-30
| | | | | | | This prevents gcc from assuming that contents of it may have changed between calls to vp56_range_get_prob(), thus preventing countless (and unnecessary) movs. Decoding of sintel trailer goes from (avg+SG) 9.796 +/- 0.003 to 9.635 +/- 0.010.
* vp8: update frame size changes on thread context switches.Ronald S. Bultje2012-05-02
| | | | | | | | | This properly synchronizes frame size changes between threads if subsequent threads abort decoding before frame size is initialized, i.e. it prevents the thread after that from ping-ponging back to the original value. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind
* cosmetics: Align codec declarationsMartin Storsjö2012-04-06
| | | | | | | Also break some long lines, remove codec function placeholder comments and add spaces in sample/pixel format lists. Signed-off-by: Martin Storsjö <martin@martin.st>
* vp8: fix update_lf_deltas in libavcodec/vp8.cJanne Salonen2012-03-24
| | | | | | | | | lf_delta.ref[i] and lf_delta.mode[i] were incorrectly reset to 0 if specific delta value was not updated. Fixed to keep the previous value if flag indicates that element in question is not updated. Signed-off-by: Janne Salonen <jsalonen@google.com> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* vp8: avoid race condition on segment map.Aaron Colwell2012-03-19
| | | | | | | | | | | This change avoids accessing the segment map of the previous frame if segmentation is not enabled for the current frame. The caller of decode_mb_mode() only calls ff_thread_await_progress() on the reference segmentation index array if segmentation is enabled, so Chromium's TSAN will report a race when accessing this data while segmentation is not enabled.

* vp8: always update next_framep[] before returning from decode_frame().Ronald S. Bultje2012-02-07
| | | | | | | | | | Also slightly move around code not allocate a new frame if we won't decode it. This prevents us from putting undecoded frames in frame pointers, which (in mt decoding) other threads will use and wait on as references, causing a deadlock (if we skipped decoding) or a crash (if we didn't initialized next_framep[] at all).

* 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.

* 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.
