c619a4e525 lavfi: make two functions static. 
ff_request_frame_to_filter() and ff_filter_frame_to_filter()
are only used in avfilter.c.

ae4650f0b9 lavfi: disallow ff_request_frame for filters using activate. 
Having two different functions allows to have stricter tests
and detect errors earlier.

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.

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.

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.

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.

44f660e7e7 lavfi: remove FF_LINK_FLAG_REQUEST_LOOP.

 2015-09-20 19:02:33 +02:00

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.

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.
