Nicolas George	c619a4e525	lavfi: make two functions static. ff_request_frame_to_filter() and ff_filter_frame_to_filter() are only used in avfilter.c.	8 years ago
Nicolas George	ae4650f0b9	lavfi: disallow ff_request_frame for filters using activate. Having two different functions allows to have stricter tests and detect errors earlier.	8 years ago
Nicolas George	02aa0701ae	lavfi: make filter_frame non-recursive. A lot of changes happen at the same time: - Add a framequeue fifo to AVFilterLink. - split AVFilterLink.status into status_in and status_out: requires changes to the few filters and programs that use it directly (f_interleave, split, filtfmts). - Add a field ready to AVFilterContext, marking when the filter is ready and its activation priority. - Add flags to mark blocked links. - Change ff_filter_frame() to enqueue the frame. - Change all filtering functions to update the ready field and the blocked flags. - Update ff_filter_graph_run_once() to use the ready field. - buffersrc: always push the frame immediately.	8 years ago
Mark Thompson	e3fb74f7f9	lavfi: Always propagate hw_frames_ctx through links Also adds a new flag to mark filters which are aware of hwframes and will perform this task themselves, and marks all appropriate filters with this flag. This is required to allow software-mapped hardware frames to work, because we need to have the frames context available for any later mapping operation in the filter graph. The output from the filter graph should only propagate further to an encoder if the hardware format actually matches the visible format (mapped frames are valid here and have an hw_frames_ctx, but this should not be given to the encoder as its hardware context).	8 years ago
Paul B Mahol	5b1907142d	avfilter: add ff_filter_get_nb_threads()	8 years ago
Paul B Mahol	547d412078	avfilter: update some comments start_frame is no more, samplesref argument is now frame argument. Signed-off-by: Paul B Mahol <onemda@gmail.com>	9 years ago
Nicolas George	1655788712	lavfi: make request_frame() non-recursive. Instead of calling the input filter request_frame() method, ff_request_frame() now marks the link and returns immediately. buffersink is changed to activate the marked filters until a frame is obtained.	9 years ago
Nicolas George	108b4de552	lavfi: replace link.closed by link.status. The status field can carry any error code instead of just EOF. Also only update it through a wrapper function and provide a timestamp. Update the few filters that used it directly.	9 years ago
Matthieu Bouron	0c59d40ae0	lavfi: use a video frame pool for each link of the filtergraph	9 years ago

Ganesh Ajjanagadde	01790484c1	avfilter/internal: add av_warn_unused_result av_warn_unused_result is added to functions whose return status should be checked. Currently does not trigger any warnings, but should be useful for future robustness.

Nicolas George	44f660e7e7	lavfi: remove FF_LINK_FLAG_REQUEST_LOOP. It has no longer any effect.	9 years ago
Nicolas George	2a351f6c55	lavfi: drop the requirement that request_frame returns a frame. It requires a loop in filters or the framework, that makes the scheduling less efficient and more complex. This is purely an internal change since the loop is now present in buffersink. Note that no filter except buffersink did rely on the requirement.	9 years ago

Anton Khirnov	bc1a985ba0	lavfi: replace avfilter_open() with avfilter_graph_alloc_filter(). Since we do not support "standalone" filters not attached to an AVFilterGraph, we should not have a public function to create such filters. In addition that function is horribly named, the action it does cannot be possibly described as "opening" a filter.	12 years ago
Nicolas George	79d8cfacf0	lavfi: loop on request_frame if necessary. Some filters need several input frames before producing output. For these filter, it becomes simpler to return 0 in request_frame() and let the framework call it again until output has been produced.	12 years ago
