* lavfi: make ff_framequeue_skip_samples() more useful.Nicolas George2017-01-29
| | | | | | | | | | Instead of just updating statistics and leaving the work to the call site, have it actually do the work. Also: skip the samples by updating the frame data pointers instead of moving the samples. More efficient and avoid writing into shared frames. Found-By: Muhammad Faiz <mfcc64@gmail.com>

* avfilter/formats: do not allow unknown layouts in ff_parse_channel_layout if ↵Marton Balint2017-01-24
| | | | | | | | | | | | | nret is not set Current code returned the number of channels as channel layout in that case, and if nret is not set then unknown layouts are typically not supported. Also use the common parsing code. Use a temporary workaround to parse an unknown channel layout such as '13c', after a 1 year grace period only '13C' will work.

* 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: 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: cosmetic: remove forward declaration.Nicolas George2017-01-12

* lavfi: add AVFilter.activate.Nicolas George2017-01-12

|
* 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: export ff_filter_set_ready() to the library.Nicolas George2017-01-12
|
* lavfi: add ff_inlink_acknowledge_status().Nicolas George2017-01-12
