Nicolas George	5cb4f1a127	vsrc_buffer: return EAGAIN if no frame is available. This is not an erroneous condition, do not print a warning. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Anton Khirnov	aff01de641	graphparser: set next to NULL on an entry extracted from inputs list Prevents it from referring to the rest of the list.	13 years ago
Anton Khirnov	7af99a01c4	graphparser: fix the order in which unlabeled input links are returned.	13 years ago
Anton Khirnov	7bf9e3391f	vsrc_buffer: fix check from `7ae7c41`. The user submitted variable in this function is frame, not buf.	13 years ago
Stefano Sabatini	91d3cbe0fd	avfiltergraph: make the AVFilterInOut alloc/free API public This is required for letting applications to create and destroy AVFilterInOut structs in a convenient way. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Anton Khirnov	12e7e1d03e	graphparser: allow specifying sws flags in the graph description.	13 years ago
Anton Khirnov	4e781c25b7	graphparser: fix the order of connecting unlabeled links. Right now, e.g. scale,[in]overlay would connect scale to the first overlay input and [in] to the second, which goes against the documentation and is unintuitive. The bug happens because of the ordering mess in curr_inputs variable: 1) the unlabeled links from the previous filter are added to it in correct order 2) input labels are parsed and inserted to the beginning one by one (i.e. in reverse order) 3) curr_inputs is matched against filter inputs in reverse order Fix the problem by always using proper ordering without trying to be clever.	13 years ago
Anton Khirnov	d7bcc71dad	graphparser: add avfilter_graph_parse2(). Unlike avfilter_graph_parse(), it returns unlinked inputs and outputs to the caller, which allows parsing of graphs where inputs/outputs are not known in advance.	13 years ago
Anton Khirnov	7ae7c41413	vsrc_buffer: allow using a NULL buffer to signal EOF.	13 years ago
Anton Khirnov	e36b25d1df	vf_overlay: implement poll_frame() Signal that it can output a frame when there are frames on the main input and EOF on the overlay input, but a frame is buffered -- e.g. single picture overlay.	13 years ago
Anton Khirnov	90f65dc6cf	vf_scale: support named constants for sws flags.	13 years ago
Anton Khirnov	a03f8ea0a8	vsrc_buffer: when no frame is available, return an error instead of segfaulting.	13 years ago
Diego Biurrun	1f068e4450	vf_unsharp: Mark readonly variable as const. This fixes the following warning: libavfilter/vf_unsharp.c:106: warning: initialization discards qualifiers from pointer target type	13 years ago
Anton Khirnov	95587d29d7	vsrc_buffer: allow buffering arbitrary number of frames.	13 years ago
Anton Khirnov	416fd90ead	vf_scale: avoid a pointless memcpy in no-op conversion. I.e. just pass the buffer along when src parameters == dst parameters.	13 years ago
Anton Khirnov	63736fe48c	avfiltergraph: try to reduce format conversions in filters. Current code, with a filterchain such as (input - yuv411) -> (scale - any) -> (sink - any) will result in yuv420 being chosen for the second link, which is clearly not right. This commit attempts to improve in the following way: repeat until convergence: loop over all filters find input link with exactly one format force this format on all output links of the same type (if possible)	13 years ago
Anton Khirnov	996f9f0c32	avfiltergraph: add an AVClass to AVFilterGraph on next major bump. It will be used for logging, possibly also AVOptions.	13 years ago
Diego Biurrun	e7e19b15c7	build: Only clean the architecture subdirectory we build for. This allows simplifying the Makefiles; it is no longer necessary to register arch subdirectory Makefiles, just putting them in place is enough.	13 years ago
Alex Converse	b0f29db5c2	Mark mutable static data const where appropriate.	13 years ago
Diego Biurrun	7331b6e718	Drop some completely unnecessary av_unused attributes.	13 years ago
Janne Grunau	456d3e4fb5	yadif: specify array size outside DECLARE_ALIGNED	13 years ago
Diego Biurrun	0bba26466f	cosmetics: Delete empty lines at end of file.	13 years ago
Anton Khirnov	38d5533228	pixdesc: mark pseudopaletted formats with a special flag. This makes it possible to dintinguish them from PAL8. Fixes an invalid write in avpicture_layout().	13 years ago
Andrey Utkin	e496c45d9b	drawtext: add 'fix_bounds' option on coords fixing Before, drawtext filter deliberately altered given text coordinates if text didn't fully fit on the picture. This breaks the use case of scrolling large text, e.g. movie closing credits. Add 'fix_bounds', to make it usable in such cases (by setting its value to 0). Default behavior is not changed, and non-fitting text coords are fixed. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Andrey Utkin	2b43dfce36	drawtext: fix text_{w, h} expression vars Before, {text_,}{w,h} vars hadn't got initialized Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Andrey Utkin	e7f0bc8c0f	drawtext: add missing braces around an if() block. Prevents uninitialized read. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago

Anton Khirnov	06e8d38f2b	Add minor bumps and APIchanges entries for lavc/lavfi changes.	13 years ago
Anton Khirnov	e1d9dbf2d4	lavfi: add a new function av_buffersrc_buffer(). It can be used to directly pass a AVFilterBufferRef to lavfi, avoiding a memcpy.	13 years ago
Stefano Sabatini	1c9e340d35	lavfi: add avfilter_copy_frame_props() avfilter_copy_frame_props() avoids code duplication and increases robustness.	13 years ago
Stefano Sabatini	b58dbb5b03	lavc: add a sample_aspect_ratio field to AVFrame The sample aspect ratio is a per-frame property, so it makes sense to define it in AVFrame rather than in the codec/stream context. Simplify application-level sample aspect ratio information extraction, and allow further simplifications.	13 years ago
