Anton Khirnov	6599b087de	buffersrc: fix a typo. Vertical shift is log2_chroma_h, not log2_chroma_w.	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
Michael Niedermayer	8152451b56	buffersrc: fix w/h error Found-by: nevcairiel Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Nicolas George	a5149607df	lavfi/buffersrc: disable deprecated warnings.	12 years ago
Nicolas George	f29c28a884	lavfi/buffersrc: check channel count changes.	12 years ago
Nicolas George	3cd342636f	lavfi/buffersrc: set channel layout if it is known. Introduced in `01649c7`, lost in the API change.	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
Hendrik Leppkes	d8dccf69ff	lavfi: let gcc realign the stack on public graph driving functions The functions which actually drive the filter graph by pushing frames through it need to ensure an aligned stack for SIMD functions. This fixes a crash in YADIF filter when using a mingw build in a MSVC application. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Clément Bœsch	bdbdadbaff	lavfi/buffersrc: raise filter_frame() error.	12 years ago
Nicolas George	b71db3f38e	lavfi/buffersrc: do not dereference NULL frame. frame = NULL is used to indicate EOF.	12 years ago
Nicolas George	b0012de420	lavfi/buffersrc: implement flags. The PUSH flags is necessary for efficient scheduling; otherwise there is no feedback when adding frames to closed paths. The NO_CHECK_FORMAT is a small optimization that does not cost much to implement. The KEEP_REF flag maps to the add/write distinction in the fork's API.	12 years ago
Anton Khirnov	7e350379f8	lavfi: switch to AVFrame. Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it and use AVFrame instead.	12 years ago
Nicolas George	01649c79c8	lavfi/buffersrc: set channel layout if it is known. If buffersrc was configured for frames with an unknown layout, the incoming frames will have channel_layout = 0. If the format negotiation has selected a known (and compatible) channel layout for the link, the frame is assumed to have that layout, the field must be set before injecting the frame in the filters.	12 years ago
Nicolas George	d2ccab5f8a	lavfi/buffersrc: forward filter_frame errors. Note: The ret variable was unused.	12 years ago
Nicolas George	ea645e90a1	lavfi/buffersrc: accept unknown channel layouts.	12 years ago
Nicolas George	5033a1af17	lavfi/buffersrc: remove init of rate and layout. The sample rate and channel layout are negotiated and set by the filter graph system, the filters must not set them.	12 years ago
Anton Khirnov	60e50dd960	buffersrc: switch to filter_frame Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	cd7febd33f	lavfi: replace filter_samples by filter_frame Based on patch by Anton Khirnov Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	565e4993c6	lavfi: merge start_frame/draw_slice/end_frame Any alleged performance benefits gained from the split are purely mythological and do not justify added code complexity.	12 years ago
Justin Ruggles	a903f8f087	Include libavutil/channel_layout.h instead of libavutil/audioconvert.h Also reorder some other #include when applicable.	12 years ago
Michael Niedermayer	6cbb8a450f	libavfilter/buffersrc: Do not fail hard on changes of input parameters. Several filters support this already. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	59ee9f78b0	lavfi: do not use av_pix_fmt_descriptors directly.	12 years ago
Mans Rullgard	568c70e79e	lavfi: convert input/ouput list compound literals to named objects A number of compilers, for example those from TI and IBM, choke on these initialisers. The current style is also quite ugly. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Anton Khirnov	716d413c13	Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormat	12 years ago
Anton Khirnov	4e48aa8656	buffersrc: add const to the AVFrame* argument of av_buffersrc_write_frame()	12 years ago
Mans Rullgard	1fce361d70	lavfi: replace empty input/output lists with null pointers Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Martin Storsjö	21bc440384	avopt: Explicitly store rational option defaults in .dbl Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	e6153f173a	avopt: Store defaults for AV_OPT_TYPE_INT in the i64 union member Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Nicolas George	5bbe4142d1	lavfi/buffersrc: add AV_BUFFERSRC_FLAG_PUSH.	12 years ago
Stefano Sabatini	42d621d131	lavfi: add priv class to filter definitions and flags to filter internal options This allows the iteration callbacks to discover the internal class and options, and show them when required.	12 years ago
Martin Storsjö	1d9c2dc89a	Don't include common.h from avutil.h Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Clément Bœsch	cc650cf029	Remove "Error parsing options string [...]" messages. This reduces from 3 to 2 messages for the same syntax error in ffprobe, and from 4 to 3 in filters.	12 years ago
Nicolas George	05776119c1	buffersrc: use avfilter_get_buffer_ref_from_frame.	13 years ago
Anton Khirnov	a8a2271fe0	buffersrc: check ff_get_audio_buffer() for errors.	13 years ago
Anton Khirnov	8f3a3ce730	lavfi: check all ff_get_video_buffer() calls for errors.	13 years ago
Anton Khirnov	785fa50f0b	buffersrc: avoid creating unnecessary buffer reference	13 years ago
Anton Khirnov	3825b52688	lavfi: check all ff_start_frame/draw_slice/end_frame calls for errors	13 years ago
Ronald S. Bultje	3db407038e	lavfi: use const for AVFilterPad declarations in all filters.	13 years ago
Nicolas George	97f86680eb	lavfi: make copy_buffer_ref common.	13 years ago
Stefano Sabatini	fda968aa8f	lavfi: decrease logging level of message showing initial parameters Reduce log clutter, consistent with `1a49a169eb`.	13 years ago
Anton Khirnov	cd99146253	lavfi: add error handling to filter_samples().	13 years ago
Stefano Sabatini	b0fdd3489a	lavfi: deprecate av_buffersrc_buffer() function Favor av_buffersrc_add_ref() instead, which is more powerful.	13 years ago
Nicolas George	05d6cc116e	buffersrc: warn when there are too many buffers.	13 years ago
Anton Khirnov	1a49a169eb	lavfi: make filters less verbose.	13 years ago
Anton Khirnov	0b3b958135	lavfi: remove disabled FF_API_VSRC_BUFFER_ADD_FRAME cruft	13 years ago
Anton Khirnov	a5e8c41c28	lavfi: remove 'opaque' parameter from AVFilter.init() It is not used in any filters currently and is inherently evil. If passing binary data to filters is required in the future, it should be done with some AVOptions-based system.	13 years ago
Stefano Sabatini	6be8cfa034	lavfi/abuffer: increase logging level of the log showing initial parameters Also show them in a more parsable/consistent fashion.	13 years ago
Stefano Sabatini	c0ca840837	lavfi/buffer: remove unused function av_vsrc_buffer_add_frame_alt()	13 years ago
Stefano Sabatini	1dce2368bb	lavfi/buffer: apply misc consistency nits	13 years ago
Stefano Sabatini	c17808cebd	lavfi: define macro AVFILTER_DEFINE_CLASS The macro can be used to define consistently the internal class of a filter, save some typing and factorize.	13 years ago
