Anton Khirnov	dd2d3b766b	lavc: Add hwaccel private data and init/uninit callbacks	11 years ago
wm4	f6774f905f	mpegvideo: operate with pointers to AVFrames instead of whole structs The most interesting parts are initialization in ff_MPV_common_init() and uninitialization in ff_MPV_common_end(). ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL checks for Picture.f, because these functions can be called on uninitialized or partially initialized Pictures. NULL pointer checks are added to ff_thread_release_buffer() stub function. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	11 years ago

Nicolas George	ea6825fd09	lavc/pthread: copy packet side data.	11 years ago
Anton Khirnov	d1f9563d50	pthread_frame: flush all threads on flush, not just the first one avcodec_flush_buffers() must release all internally held references according to its documentation, for which all the threads need to be flushed. CC:libav-stable@libav.org Bug-Id: vlc/9665	11 years ago
Anton Khirnov	9cbf2d78f0	pthread_frame: unref decoded frames on failure This is similar to what the non-threaded code already does. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Michael Niedermayer	11679e1b90	avcodec/pthread_frame: Fix memleak of AVCodecContext on error Fixes CID1135767 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	d351ef47d0	pthread_frame: use the AVFrame API properly. Remove the extended_data workaround, all decoders should now handle this properly.	11 years ago
Hendrik Leppkes	841c0aafa5	avcodec/pthread: check packet buffer allocation Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	a553c6a347	lavc: use buf[0] instead of data[0] in checks whether a frame is allocated data[0] may be NULL for valid frames with hwaccel pixel formats.	11 years ago
Anton Khirnov	da6506c607	lavc: move AVCodecContext.pkt to AVCodecInternal It's a private field, not meant to be accessed from outside lavc.	11 years ago
Anton Khirnov	38ecc3702d	pthread: store thread contexts in AVCodecInternal instead of AVCodecContext It's a private field, it should not be visible to callers. Deprecate AVCodecContext.thread_opaque	11 years ago
Anton Khirnov	cc14ee03a7	lavc: split slice and frame threading functions into separate files	11 years ago
Anton Khirnov	5cd6513f5b	pthread: drop avcodec_ prefixes from static functions	11 years ago
Anton Khirnov	a1504eee41	lavc: deprecate AVCodecContext.debug_mv It has been unused since `37045e4229`.	11 years ago
Mickaël Raulet	e146c326b9	avcodec/pthread: add wpp api cherry picked from commit c7765f3295fe7dc0653161c6a3d3e1778b76ee67 cherry picked from commit 0008c4979fc1d1bc24d4d2c791715f6dd017563c Conflicts: libavcodec/utils.c Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Ben Jackson	5152196b2b	pthread: Avoid spurious wakeups pthread_wait_cond can wake up unexpectedly (Wikipedia: Spurious_wakeup). The FF_THREAD_SLICE thread mechanism could spontaneously execute jobs or allow the caller of avctx->execute to return before all jobs were complete. Test both cases to ensure the wakeup is real.

Derek Buitenhuis	eb90a2091f	pthread: Fix deadlock during thread initialization Sometimes, if pthread_create() failed, then pthread_cond_wait() could accidentally be called in the worker threads after the uninit function had already called pthread_cond_broadcast(), leading to a deadlock. Don't call pthread_cond_wait() if c->done is set. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago

Sean McGovern	50612484e0	pthread: Rename thread_init to avoid symbol collision The AIX threads library exposes a function with the same name. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Carl Eugen Hoyos	674d8a9629	Rename thread_init() in libavcodec and libavfilter as library_thread_init(). The aix header sys/thread.h contains a definition for thread_init().	12 years ago

Michael Niedermayer	42bb3e4db6	avcodec: remove ff_get_logical_cpus() This simplifies the code Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	2a6eaeaa85	Move get_logical_cpus() from lavc/pthread to lavu/cpu. It will be useful in lavfi, and could conceivably be useful to the user applications as well.	12 years ago

Anton Khirnov	30e256430e	lavc/pthread: remove obsolete checks Those were useful when avcodec_thread_init() was a public functions. It was deprecated and removed some time ago, so those checks are not needed anymore.	12 years ago

Michael Niedermayer	94b3a666fa	avcodec/pthread: Make sure ff_thread_finish_setup() conditions match Prevents warning from being shown due to multiple calls. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Janne Grunau	94660c3524	threads: always call thread_finish_setup for intra codecs Intra codecs do not need an update_thread_context() function and never call ff_thread_finish_setup(). They rely on ff_thread_get_buffer() calling it. So call it even if the get_buffer2 function pointer is avcodec_default_get_buffer2 and it has not been called before.	12 years ago
Reimar Döffinger	c10d498bfd	Add thread-safe wrapper for get_format(). Just like get_buffer, get_format should not be called from a different thread if thread_safe_callbacks is not set. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	12 years ago
Janne Grunau	05fa79b844	hwaccel: fix use with frame based multithreading Allows use of AVHWAccel based decoders with frame based multithreading. The decoders will be forced into an non-concurrent mode by delaying ff_thread_finish_setup() calls after decoding of the current frame is finished. This wastes memory by unnecessarily using multiple threads and thus copies of the decoder context but allows seamless switching between hardware accelerated and frame threaded software decoding when the hardware decoder does not support the stream.	12 years ago
Hendrik Leppkes	c71c80f53b	pthread: unref already decoded frames when flushing the decoder Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
