* avfilter/formats: Remove unused functionsAndreas Rheinhardt2020-08-21
| | | | | | | | | | | | | | This commit removes ff_parse_sample_format(), ff_parse_time_base() and ff_query_formats_all_layouts() from libavfilter/formats.c. All of these functions were completely unused. ff_parse_time_base() has not been used at all since it had been added in 3448404a707b6e236a2ffa7b0453b3300de41b7b; the last caller of ff_parse_sample_format has been removed in commit d1c49bcae9b7fd41df5c6804ac7f6a5c271a7c2e. And the one and only caller of ff_query_formats_all_layouts() (the asyncts filter) has been removed in commit a8fe8d6b4a35c95aa94fccde5f001041278d197c.

| * lavfi: Always propagate hw_frames_ctx through linksMark Thompson2016-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).
* | 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: 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: 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.
