* lavfi: make two functions static.Nicolas George2017-01-12
| | | | | ff_request_frame_to_filter() and ff_filter_frame_to_filter() are only used in avfilter.c.
* lavfi: disallow ff_request_frame for filters using activate.Nicolas George2017-01-12
| | | | | Having two different functions allows to have stricter tests and detect errors earlier.
* lavfi: add ff_inlink_request_frame().Nicolas George2017-01-12
|
* lavfi: move ff_update_link_current_pts() into the utility functions.Nicolas George2017-01-12
| | | | | | It does not change anything for the existing filters and makes better code fatrorization when future code will use the utility functions.

* lavfi: implement ff_inlink_make_frame_writable().Nicolas George2017-01-12
| | | | | | | | Unlike av_frame_is_writable(), it uses the link's alloc callback, making direct rendering possible. The code comes from ff_filter_frame_framed(), moved with mostly trivial changes.

* lavfi: add ff_inlink_acknowledge_status().Nicolas George2017-01-12
| | | | | Also introduce libavfilter/filters.h for all functions needed to implement filters.

* lavfi: make filter_frame non-recursive.Nicolas George2016-12-18
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* lavfi: split frame_count between input and output.Nicolas George2016-11-13
| | | | | | | | | | | | AVFilterLink.frame_count is supposed to count the number of frames that were passed on the link, but with min_samples, that number is not always the same for the source and destination filters. With the addition of a FIFO on the link, the difference will become more significant. Split the variable in two: frame_count_in counts the number of frames that entered the link, frame_count_out counts the number of frames that were sent to the destination filter.

| * lavfi: set the link hwframes context before configuring the dst inputAnton Khirnov2016-06-25

* | lavfi: make request_frame() non-recursive.Nicolas George2015-12-22
| | | | | | | | | | | | | | 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.
* | lavfi: replace link.closed by link.status.Nicolas George2015-12-22
| | | | | | | | | | | | 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.

* | lavfi: drop the requirement that request_frame returns a frame.Nicolas George2015-09-20
| | | | | | | | | | | | | | | | 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.
