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
Matt Wolenetz	252c0bfdc0	lavc: Fix msvc compilation of utils.c with -WX (warnings treated as errors) This fixes https://bugzilla.libav.org/show_bug.cgi?id=514. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Luca Barbato	e55e8b2c36	lavc: do not leak frames in avcodec_decode_audio4 Notwithstanding the return value the frame should be freed if is not going to be used. Reported-by: Matthew Wolenetz <wolenetz@chromium.org>	12 years ago
Diego Biurrun	6fee1b90ce	avcodec: Add av_cold attributes to init functions missing them	12 years ago
Diego Biurrun	088f38a4f9	avcodec: Drop unnecessary ff_ name prefixes from static functions	12 years ago
Anton Khirnov	e036bb7899	lavc: clear AVBuffers on decoded frames if refcounted_frames is not set Otherwise some code might mistakenly think it is allowed to unref those buffers, which would lead to double unref.	12 years ago
Anton Khirnov	a7f46586bf	ff_get_buffer(): allocate the frame for max(coded,display) dimensions Needed e.g. for h264 cropping to work properly.	12 years ago
Anton Khirnov	9de9b828ef	lavc: don't overwrite display dimensions with coded dimensions.	12 years ago
Ronald S. Bultje	b93b27edb0	dsputil: Make dsputil selectable Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Janne Grunau	c24469e812	utils: add workaround for AVHWAccel in ff_get_buffer compat code Since `c977039e58` plane count for PIX_FMT_HWACCEL pixel formats is 0 instead of 1. The created dummy AVBuffers are still bogus since AVFrame does not hold frame data when AVHWAccels are used.	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
Martin Storsjö	75644335b9	lavc: Move start code finding to utils.c This allows dropping the mpegvideo dependency from a number of components. This also fixes standalone building of the h264 parser, which was broken in `64e438697`. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Anton Khirnov	c977039e58	lavc, lavfi: fix counting number of planes in AVBufferRef wrappers Number of planes is not always equal to the number of components even for formats marked with PIX_FMT_PLANAR -- e.g. NV12 has three components in two planes.	12 years ago
Anton Khirnov	6552808014	lavc,lavfi: fix calculating the plane size in the AVBufferRef wrappers It is supposed to be height * linesize, not width * linesize. Thanks to Hendrik Leppkes for pointing out the bug.	12 years ago
Diego Biurrun	f099d3d1d5	Add av_log_{ask_for_sample\|missing_feature} replacements to libavutil This allows reporting missing features and requesting samples from all libraries in a standard way; with a simplified API.	12 years ago
Janne Grunau	a2816230c5	avframe: call release_buffer only if it is set AVCodecContext release_buffer() shall be NULL for audio codecs using get_buffer. The backward compatibility code hence have to check before calling it.	12 years ago
Anton Khirnov	669cc0f364	lavc: fix get_buffer() compatibility layer for audio. planes - FF_ARRAY_ELEMS would be evaluated as unsigned and underflow instead of being negative as was intended.	12 years ago
Anton Khirnov	0f24a3ca99	lavc: remove disabled FF_API_OLD_ENCODE_VIDEO cruft	12 years ago
Anton Khirnov	f073b1500e	lavc: remove disabled FF_API_OLD_ENCODE_AUDIO cruft	12 years ago
Anton Khirnov	5d606863c3	lavc: remove disabled FF_API_OLD_DECODE_AUDIO cruft	12 years ago
Anton Khirnov	7c45087b84	lavc: update the fallback versions of ff_thread_* Fixes build without threads after `759001c534`.	12 years ago
Anton Khirnov	2eba9087f3	lavc: make up a fake frame channel layout when there is no real one. This should ensure that a valid channel layout is always set on a frame, until a better solution is implemented.	12 years ago
Anton Khirnov	15ec0450b4	lavc: allow decoders to override frame parameters.	12 years ago
