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	62144b225d	avfilter/internal: Doxygen for ff_fmt_is_in This clarifies and adds Doxygen for ff_fmt_is_in. Reviewed-by: Timothy Gu <timothygu99@gmail.com> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	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	1565cbc65c	lavfi: make avfilter_free() remove the filter from its graph.	12 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
Anton Khirnov	7e350379f8	lavfi: switch to AVFrame. Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it and use AVFrame instead.	12 years ago

Nicolas George	9de731e9d0	lavfi/sink_buffer: implement libav compatibility API. Implement av_buffersink_read() and av_buffersink_read_samples() for ffmpeg's version of buffersink.
