Anton Khirnov	9d0bfc5052	lavfi: make AVFilterPad opaque after two major bumps. It will allow adding new fields to it without ABI breaks.	13 years ago
Anton Khirnov	6d58358a3a	lavfi: make avfilter_get_video_buffer() private on next bump. They are only useful inside filters and we don't allow user filters for now.	13 years ago
Nicolas George	0f62125643	buffersrc: deprecate flat options syntax.	13 years ago
Nicolas George	9ca440679d	buffersrc: accept the frame rate as argument.	13 years ago
Nicolas George	dcaa4efcee	buffersrc: accept key=value arguments. The current flat arguments syntax is not easily extensible due to sws_param possibly containing commas. This is also consistent with abuffersrc.	13 years ago
Anton Khirnov	803391f719	lavfi: remove request/poll and drawing functions from public API on next bump They are only useful inside filters and we don't allow user filters for now.	13 years ago
Anton Khirnov	b74a1da49d	lavfi: make formats API private on next bump. It is only useful inside filters and we don't allow user filters for now.	13 years ago
Stefano Sabatini	0f0f3bd1e0	lavfi: use av_default_item_name() as filter private context logger avfilter_default_filter_name() is supposed to access an AVFilterContext struct, if used with a private struct it will cause a crash since it will access fields which are non defined in the private struct.	13 years ago
Stefano Sabatini	4d6a8a2bdb	lavfi: add avfilter_default_filter_name() The function is modelled after av_default_item_name(), and will print the name of the instance filter if defined, otherwise the name of the filter. This allows to show the instance name in the log, which is useful when debugging complex filter graphs.	13 years ago
Michael Niedermayer	a5c7525bcb	set some categories of some AVClass structs Please help setting the category for all remaining AVClasses Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	6adefeef45	buffersrc: cosmetic: reindent.	13 years ago
Nicolas George	aa1246ea42	lavfi: unify src_buffer and buffersrc. Most of the code is moved to buffersrc.c to help Git see the similarities. src_buffer.c still contains the obsolete compatibility functions. The format change detection code was removed as it has been implemented directly in ffmpeg. It can easily be brought back from the history.	13 years ago
Michael Niedermayer	3e2cf79e15	buffersrc: export forgotten function Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	4c66c40718	lavfi: add an audio buffer source.	13 years ago
Anton Khirnov	720c6b78d1	buffersrc: add av_buffersrc_write_frame(). It's the same as av_vsrc_buffer_add_frame(), except it doesn't take pts or pixel_aspect parameters. Those are read from AVFrame. Deprecate av_vsrc_buffer_add_frame().	13 years ago
Anton Khirnov	8b05e13df3	buffersrc: fix invalid read in uninit if the fifo hasn't been allocated	13 years ago
Anton Khirnov	fad729fa50	lavfi: rename vsrc_buffer.c to buffersrc.c Most of the code will be shared for both audio and video version.	13 years ago
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
Nicolas George	2ae5af8094	lavfi: rename vsrc_buffer.c into src_buffer.c.	13 years ago
Nicolas George	7ad0d9864e	lavfi: merge asrc_abuffer into vsrc_buffer.	13 years ago
Nicolas George	2d6522bab0	vsrc_buffer: count the number of failed requests.	13 years ago
Nicolas George	f75ee4031e	vsrc_buffer: return EAGAIN if no frame is available. This is not an erroneous condition, do not print a warning.	13 years ago
Michael Niedermayer	5cd460ba63	vsrc_buffer: fix null ptr segfault Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
Anton Khirnov	7ae7c41413	vsrc_buffer: allow using a NULL buffer to signal EOF.	13 years ago
Michael Niedermayer	25eae29ea1	vsrc_buffer: remove overwrite support. the overwrite flag became unused when merging support for buffering multiple frames. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	a03f8ea0a8	vsrc_buffer: when no frame is available, return an error instead of segfaulting.	13 years ago
Anton Khirnov	95587d29d7	vsrc_buffer: allow buffering arbitrary number of frames.	13 years ago
Michael Niedermayer	2d54bbb950	vsrc_buffer: Store allocated scale filter and free it later. Fixes a memleak. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	43fe6a2905	vsrc_buffer: release the buffer on uninit.	13 years ago
Anton Khirnov	5d25140f71	vsrc_buffer: error on changing frame parameters.	13 years ago
Diego Biurrun	3dc99a18d4	cosmetics: drop some pointless parentheses	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
Reimar Döffinger	5af7daabc4	Mark AVFilterPad[] compound literals as const. GCC 4.6.2 at least still seems to fail to put them in .rodata though, see also http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37303 Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Michael Niedermayer	2982b02b79	vsrc_buffer: FIx incompatible pointer type warning Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Stefano Sabatini	e26782a9b4	lavfi: add ff_parse_pixel_format() internal function, and use it Reduce code duplication.	13 years ago
Mina Nagy Zaki	fd2c0a5db2	lavfi: add layout negotiation fields and helper functions.	14 years ago
Stefano Sabatini	27bcf55f45	vsrc_buffer: add flags param to av_vsrc_buffer_add_video_buffer_ref The new flags parameter allows to specify if the video ref to add should overwrite the cache, if the flag is not set vsrc_buffer will complain and abort; otherwise it will clean the already cached video ref before to overwrite it, thus avoiding a leak.	14 years ago
Stefano Sabatini	9e66b64c36	vsrc_buffer: propagate error code in av_vsrc_buffer_add_frame() Propagate av_vsrc_buffer_add_video_buffer_ref() error code rather than return 0.	14 years ago
Stefano Sabatini	cf06e3e4dd	vsrc_buffer: return an error code if no frames are available Also decrease the log level of the corresponding message to WARNING, since the error is not fatal.	14 years ago
Stefano Sabatini	f7053dc41a	vsrc_buffer: tweak error message in init() Change: Expected 7 arguments, but only %d found in '%s'\n to: Expected 7 arguments, but %d found in '%s'\n as the user may provide more than 7 arguments, in that case the error is not misleading. Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Stefano Sabatini	c000a9f783	vsrc_buffer: add av_vsrc_buffer_add_frame() The new function is a wrapper around av_vsrc_buffer_add_video_buffer_ref(), and allows to simplify the act of pushing AVFrame data to the source buffer.	14 years ago
Stefano Sabatini	50764e19a8	vsrc_buffer: make the source accept sws_param in init Avoid the need of two distinct av_vsrc_add_video_buffer_ref* functions. Simplify the interface.	14 years ago
Stefano Sabatini	509b32cf5d	vsrc_buffer: propagate avfilter_open() error code	14 years ago
Stefano Sabatini	3799805e56	vsrc_buffer: fix style	14 years ago
Stefano Sabatini	6070b7e1c5	vsrc_buffer: remove dependency on AVFrame Rename av_vsrc_buffer_add_frame to av_vsrc_buffer_add_video_buffer_ref(), and change its inteface to make it accept in input an AVFilterBufferRef rather than an AVFrame. This way the interface can be used without requiring the inclusion/installation of libavcodec headers.	14 years ago
Stefano Sabatini	ea7f73c52e	vsrc_buffer: during init, print information about timebase and sample aspect ratio	14 years ago
Stefano Sabatini	64c06615d2	vsrc_buffer: simplify av_vsrc_buffer_add_frame*() interface Now that pix_fmt, width, and height are directly embedded in the AVFrame, there is no need to pass these values as separate arguments.	14 years ago
Stefano Sabatini	566666caf3	lavfi: add libavfilter/avcodec.h and avfilter_copy_frame_props() avfilter_copy_frame_props() avoids code duplication and increases robustness. The added files libavfilter/avcodec.[ch] are used for containing utilities useful for gluing togheter libavfilter and libavcodec.	14 years ago
