* lavfi: check links properties after configuring them.Nicolas George2017-11-02
| | | | | | | | For now, check the image size. Inspired by a patch from Paul B Mahol. Invalid sizes would be detected later by allocation failures, detecting problems earlier is cleaner.

* | lavfi: do not call ff_filter_frame() with activate.Nicolas George2017-01-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | avfilter_graph_request_oldest() does work that should be done by either the filter or the application. The principle of this function, calling ff_request_frame() from outside the filter was always shaky. This version is less elegant since it requires making special cases for each filter, but it is more robust since it no longer calls ff_request_frame() directly without notifying the filter. Eventually, avfilter_graph_request_oldest() will be deprecated for a function to just run the graph.
* | lavfi, ffmpeg: simplify filter names.Nicolas George2017-01-12
| | | | | | | | | | | | The names are only used for technical output and debugging. Make them similar to C identifiers for easier quick reading of debug dumps.
* | lavfi: avfilter_graph_request_oldest: request a frame again before returning.Nicolas George2016-12-23
| | | | | | | | | | | | | | | | | | With min_samples, if a frame arrives but is too small, it clears frame_wanted_out. In most cases, the destination filter would be activated again later because of frame_wanted_out on its own outputs, but not sinks. avfilter_graph_request_oldest() is doing the work of the sink itself, and is therefore allowed to use frame_blocked_in.
* | 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: rename link.current_pts to current_pts_us.Nicolas George2015-12-22

* | avfilter/all: propagate errors of functions from avfilter/formatsGanesh Ajjanagadde2015-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM). This propagates the return values. All of these were found by using av_warn_unused_result, demonstrating its utility. Tested with FATE. I am least sure of the changes to avfilter/filtergraph, since I don't know what/how reduce_format is intended to behave and how it should react to errors. Fixes: CID 1325680, 1325679, 1325678.

* | lavfi: check refcount before merging.Nicolas George2014-07-17
| | | | | | | | | | | | | | | | | | | | When merging the formats around the automatically inserted convert filters, the refcount of the format lists can not be 0. Coverity does not detect it, and suspects a memory leak, because if refcount is 0 the newly allocated lists are not stored anywhere. That gives CIDs 1224282, 1224283 and 1224284. Lists with refcount 0 are used in can_merge_formats(), so the asserts can not be moved inside the merge functions.
