Anton Khirnov	1b04eb20f7	lavc: do not allocate edges in the default get_buffer2()	11 years ago
Justin Ruggles	9e500efdbe	Add av_image_check_sar() and use it to validate SAR	11 years ago
wm4	eb800f120d	libavcodec: set AVFrame colorspace fields on decoding Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Vittorio Giovara	bddd8cbf68	Add transformation matrix API. Add AV_PKT_DATA_DISPLAYMATRIX and AV_FRAME_DATA_DISPLAYMATRIX as stream and frame side data (respectively) to describe a display transformation matrix for linear transformation operations on the decoded video. Add functions to easily extract a rotation angle from a matrix and conversely to setup a matrix for a given rotation angle. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Anton Khirnov	e1b66778b6	lavc: remove the locking code in avcodec_close() This function should not modify any global state, so there should be no reason for any locking.	11 years ago
Anton Khirnov	dd2d3b766b	lavc: Add hwaccel private data and init/uninit callbacks	11 years ago
Luca Barbato	ebc29519d1	hwaccel: Support specific frame allocators It would reduce the boilerplate code users have to write.	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	e7fc9796d8	lavc: do not use AVCodecContext.codec_name in avcodec_string() That field will be deprecated.	11 years ago
Vittorio Giovara	6ef96292d9	utils: add yvyu422 to avcodec_align_dimensions2	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
Anton Khirnov	4a0f665143	libavcodec: when decoding, copy replaygain side data to decoded frames	11 years ago
Anton Khirnov	8feac29cc4	lavc: use AVFrame API properly in ff_reget_buffer()	11 years ago
John Stebbins	52771346dc	lavc: set AVFrame pkt_pts and reordered_opaque in reget_buffer Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Diego Biurrun	190d4a447b	avcodec: Suppress deprecation warnings from avcodec_alloc_frame() The function is itself obsolete and slated for removal.	11 years ago
Anton Khirnov	e0ab5078a7	lavc: do not force the emu edge flag The default get_buffer2() implementation (and possibly some user ones) does not allocate edges when this flag is set, which may expose bugs in some decoders. Until the 10 release is out, it is safer to remove this part.	11 years ago
Anton Khirnov	93c553c71e	lavc: deprecate CODEC_FLAG_EMU_EDGE and avcodec_get_edge_width().	11 years ago
Anton Khirnov	f7e85ee996	lavc: allow the caller to override dimensions in ff_get_buffer() This will be useful for allocating edges in the encoders.	11 years ago
Anton Khirnov	50079a6aa9	lavc: do not leak the internal frame if opening the codec fails	11 years ago
Anton Khirnov	8058284ce0	lavc: add 422/444 YUV with alpha to align_dimensions() Aligns frame dimensions to 16, which fixes potential invalid writes.	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	d7b3ee9a3a	lavc: deprecate avcodec_get_frame_defaults(). Also bump libavcodec micro and add an APIchanges entry saying that av_frame_* should now be used instead of the lavc AVFrame functions.	11 years ago
Anton Khirnov	95a8a5aca6	lavc: call av_frame_unref() instead of avcodec_get_frame_defaults(). avcodec_get_frame_defaults() will be deprecated.	11 years ago
Anton Khirnov	9431356218	lavc: deprecate avcodec_free_frame() av_frame_free() should be used instead.	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
Anton Khirnov	a1ee164869	lavc/decode_video(): always unref the frame if there is no output in decode_video Not just on failure. This is the same thing that is done in the audio path and should prevent leaks in decoders that allocate a frame, but then end up not writing into it.	11 years ago
Anton Khirnov	85f947aefb	lavc: remove a pointless check in decode_audio4() av_frame_unref() works fine on unallocated frames.	11 years ago
Anton Khirnov	d4f0f2d1e8	lavc: use buf[0] instead of data[0] as the indicator of an allocated frame data[0] may be NULL for valid frames with hwaccel pixel formats.	11 years ago
Anton Khirnov	e5419709f5	lavc: remove the extended_data workarounds. All decoders should now handle it properly.	11 years ago
Anton Khirnov	b9fb59d2ab	lavc: deprecate avcodec_alloc_frame().	11 years ago
Anton Khirnov	5b9c3b4505	Replace all instances of avcodec_alloc_frame() with av_frame_alloc().	11 years ago
Anton Khirnov	cce3e0a49f	Move av_fast_{m,re}alloc from lavc to lavu.	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	0f6c1d6d64	lavc/utils: stop using deprecated avcodec_set_dimensions	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
Anton Khirnov	b9589f5a77	lavc: add error checking to apply_param_change.	11 years ago
Paul B Mahol	7e52080cb1	pcm: support 24-bit/32-bit little-endian planar Used by LXF. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Diego Biurrun	e95930eda1	avcodec/utils: Simplify a condition that combines HAVE_NEON and ARCH_ARM	11 years ago
Diego Biurrun	7950e519bb	Disable deprecation warnings for cases where a replacement is available	11 years ago
Anton Khirnov	720a1de52f	lavc: free the padded last frame during audio encoding properly	12 years ago
Janne Grunau	985f34b756	utils: fix avcodec_flush_buffers pre-reference counting compatibility The to_free AVframe must be freed just like the other ones. Indeed, the calling application may expect all frames to be released. (This regression caused use-after-free in VLC with hwaccel.) Signed-off-by: Rémi Denis-Courmont <remi@remlab.net> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Anton Khirnov	799f57ac96	lavc: use AVFrame API properly in pad_last_frame(). This also simplifies the code.	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
Anton Khirnov	e6c4ac7b5f	pixdesc: rename PIX_FMT_* flags to AV_PIX_FMT_FLAG_*	12 years ago
