Vittorio Giovara	85dc006b1a	lavc: fix bitshifts amount bigger than the type CC: libav-stable@libav.org Bug-Id: CID 1194387 / CID 1194389 / CID 1194393 / CID 1206638	10 years ago
Justin Ruggles	9e500efdbe	Add av_image_check_sar() and use it to validate SAR	11 years ago
Anton Khirnov	dd2d3b766b	lavc: Add hwaccel private data and init/uninit callbacks	11 years ago
Anton Khirnov	5c1d7246cd	lavc: set AVCodecContext.hwaccel in ff_get_format() This way each decoder does not have to do the same thing manually.	11 years ago
Anton Khirnov	632ad2248e	lavc: Add an internal wrapper around get_format() It will be useful in the following commits.	11 years ago
Anton Khirnov	4a0f665143	libavcodec: when decoding, copy replaygain side data to decoded frames	11 years ago
Tim Walker	5b4797a21d	avframe: add AV_FRAME_DATA_MATRIXENCODING side data type. Includes a libavcodec utility function to update a frame's side data.	11 years ago
Anton Khirnov	37a749012a	lavc: rework handling of refcounted_frames=0 Use only proper AVFrame API (no assigning of whole frames, since that hardcodes sizeof(AVFrame) into lavc). Make a copy of the side data, so the caller can use av_frame_unref/free on non-refcounted frames, eliminating the need for avcodec_get_frame_defaults()/avcodec_free_frame().	11 years ago
Luca Barbato	08303d7741	hwaccel: Simplify ff_find_hwaccel It is always called by passing fields from an AVCodecContext.	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	7644f5a807	lavc: replace avcodec_set_dimensions with ff_set_dimensions avcodec_set_dimensions() is supposed to be an internal utility function, there is no reason whatsoever for it to be public. Therefore deprecate it.	11 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
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
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_*	13 years ago
Anton Khirnov	a5117a2444	lavc: pad last audio frame with silence when needed.	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
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
Anton Khirnov	84626b364b	lavc: add support for codec-specific defaults.	14 years ago

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
Gwenole Beauchesne	d7dae42e70	Add missing prototype for ff_is_hwaccel_pix_fmt(). patch by Gwenole Beauchesne, gbeauchesne,splitted-desktop,com Originally committed as revision 17593 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Kenan Gillet	0ba39dd1a9	Split ff_log_missing_feature into ff_log_missing_feature and ff_log_ask_for_sample. Patch by Kenan Gillet: gmail_adress(author) Originally committed as revision 16637 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Stefano Sabatini	987903826b	Globally rename the header inclusion guard names. Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Diego Biurrun	5b21bdabe4	Add FFMPEG_ prefix to all multiple inclusion guards. Originally committed as revision 10765 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
