Michael Niedermayer	42bb3e4db6	avcodec: remove ff_get_logical_cpus() This simplifies the code Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Martin Storsjö	f1e9398621	lavc: Rename avpriv_mpv_find_start_code after moving out from mpegvideo Also move the declaration to internal.h, and add restrict qualifiers to the declaration (as in the implementation). Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Anton Khirnov	f073b1500e	lavc: remove disabled FF_API_OLD_ENCODE_AUDIO cruft	12 years ago
Anton Khirnov	192f1984b1	lavc: limit maximum number of channels to 63 This is the most that can be represented with the current channel layout system. This limit should be raised/removed when a better system is implemented.	12 years ago
Anton Khirnov	759001c534	lavc decoders: work with refcounted frames.	12 years ago
Diego Biurrun	5a4e9fe855	avcodec/internal: Fix #if DECODE_AUDIO / ENCODE_AUDIO name mismatch	12 years ago
Michael Niedermayer	bf90ef0314	avcodec: add ff_frame_get_metadatap() This is needed for av_dict_* Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	a3a97129e7	mpegvideo: make ff_print_debug_info independant of mpegvideo Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	a53b144ec0	avcodec: add avpriv_color_frame() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Clément Bœsch	67286fa98b	10l: export ff_bprint_to_extradata between libs using avpriv_ prefix. Both libavformat and libavcodec requires this function.	12 years ago
Clément Bœsch	36e61e24e7	lavc: add ff_bprint_to_extradata() helper and use it. This commit also makes sure the extradata and subtitle_header are NUL terminated, without taking into account the trailing '\0' in account in the size. At the same time, it should fix 'warning: dereferencing type-punned pointer will break strict-aliasing rules' warning for compilers who don't consider uint8_t and char compatibles.	12 years ago
Reimar Döffinger	25fec8595d	avcodec: add ff_lock/unlock_avcodec functions. Will be used in future patches, together with the variable that allows checking whether the lock is held. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	12 years ago
Anton Khirnov	e57c4706e9	lavc: don't reuse audio buffers Any performance gain from this is negligible and not worth the extra code.	12 years ago
Anton Khirnov	594d4d5df3	lavc: add a wrapper for AVCodecContext.get_buffer(). It will be useful in the upcoming transition to refcounted AVFrames.	12 years ago
Luca Barbato	cc085993f4	avcodec: remove ff_is_hwaccel_pix_fmt It is used only in one place and is unlikely it would be needed elsewhere.	12 years ago
Justin Ruggles	bb6941af2a	lavc: move SANE_NB_CHANNELS to internal.h and use it in the PCM decoders	12 years ago
Ash Hughes	2470851f12	lavc: enable recursively using avcodec_open2/close. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	716d413c13	Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormat	12 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	12 years ago
Stefano Sabatini	44bd69e9b9	lavc/utils: rename ff_init_buffer_info() pic parameter to frame The new name is more expressive, given that the frame is not necessarily a picture but may be an audio frame.	12 years ago
Michael Niedermayer	2fe186409b	lavc: skip initial silence when requested Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	bafa1c7f38	h264: add avpriv_h264_has_num_reorder_frames() This function exports the exact sps.num_reorder_frames value Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	fde1bc64ad	lavc: add frame multithreading capability (currently intra only) Compared to the decoder side, this code is able to change both the delay and the number of threads seamlessly during encoding. Also any idle thread can pick up tasks, the strict round robin in order limit is gone too. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	0c851e4642	threads: make get_logical_cpus() available outside pthread.c Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	a5117a2444	lavc: pad last audio frame with silence when needed.	13 years ago
Michael Niedermayer	6952301f33	ff_samples_to_time_base: support AV_NOPTS_VALUE Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	59a4b73531	pthread/mpegvideo: detect and block attempts to init frames after setup. This fixes race conditions that ultimately lead to memory corruption. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	740b9ff44e	lavc: Redesign the internal encoding API. The new API allows (optionally and on by default) using a internal buffer to encode, avoiding the need to allocate large buffers or risking failure on too small buffers. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	00663de3b7	lavc: add ff_alloc_packet2(). This contains a AVCodecContext thus allowing us to prevent the error message duplication Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Justin Ruggles	91a28b0e8e	avcodec: add ff_samples_to_time_base() convenience function to internal.h	13 years ago
Justin Ruggles	1a670973a7	ff_alloc_packet: modify the size of the packet to match the requested size This will simplify encoders which use this function to request the exact packet size rather than the maximum size.	13 years ago
Justin Ruggles	b2c75b6e63	avcodec: Add avcodec_encode_audio2() as replacement for avcodec_encode_audio() This allows audio encoders to optionally take an AVFrame as input and write encoded output to an AVPacket. This also adds AVCodec.encode2() which will also be usable by video and subtitle encoders once support is implemented in the public functions.	13 years ago
Reimar Döffinger	c4ba5198ea	Fix leaking of side data. While we correctly "register" the side data when we split it, the application (in this case FFmpeg) might not update the AVPacket pool it uses to finally free the packet, thus causing a leak. This also makes the av_dup_packet unnecessary which could cause an even worse leak in this situation. Also change the code to not modify the user-provide AVPacket at all. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Alex Converse	4df30f7114	utils: Check for extradata size overflows.	13 years ago
Mans Rullgard	8400b126ac	avcodec: deprecate AVFrame.age This was intended as an optimisation for skipped blocks in MPEG2 P-frames and never used elsewhere. Removing this "optimisation" speeds up MPEG2 decoding by 1-2% (ARM Cortex-A9). Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Justin Ruggles	0eea212943	Add avcodec_decode_audio4(). Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.	13 years ago
Justin Ruggles	f3a29b750a	avcodec: move some AVCodecContext fields to an internal struct. 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.	13 years ago
Martin Storsjö	2d1b6fb72b	avcodec: Allow locking and unlocking an avformat specific mutex This extends the lock manager in avcodec to manage two separate mutexes via the user-specified lock functions. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Anton Khirnov	0842d58998	lavc: use avpriv_ prefix for ff_toupper4. It's used in lavf.	13 years ago
Michael Niedermayer	b93cb8383f	lavc: add ff_init_buffer_info() Fixes seeking per fileposition in ffplay. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	84626b364b	lavc: add support for codec-specific defaults.	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands.

Stefano Sabatini	bf7e799c9e	Remove '\p', '\c' and '\e' doxygen markup from doxy, as it should improve plain text doxy readability. See the thread: "[RFC] Should we use doxygen markup?". Originally committed as revision 19122 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
