* 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>
* lavc: fix decode_frame() third parameter semantics for video decodersAnton Khirnov2012-12-04
| | | | It's got_frame, not data size

* 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: refactor decoding a single mb_rowDaniel Kang2012-07-14
| | | | | | This is in preperation for sliced threading. 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).

* vp8: flush buffers on size changes.Aaron Colwell2011-12-02
|
* 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.

* Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 ↵Oskar Arvidsson2011-05-10
| | | | | | | | | | | | | | | | | decoder. This patch lets e.g. dsputil_init chose dsp functions with respect to the bit depth to decode. The naming scheme of bit depth dependent functions is <base name>_<bit depth>[_<prefix>] (i.e. the old clear_blocks_c is now named clear_blocks_8_c). Note: Some of the functions for high bit depth is not dependent on the bit depth, but only on the pixel size. This leaves some room for optimizing binary size. Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

| | | | | 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.
