Nicolas George	76613618d9	lavfi: add helper functions and macros for activate.	7 years ago
Nicolas George	f5a9c63401	lavfi: guess a timestamp for compat status change. Use the earliest input with the same status. If that fails, print a warning and use the earliest source. With this change, simple filter forward correctly the timestamp of EOF. Filters that are supposed to change it should be updated to actually forward it.	7 years ago
Nicolas George	dfa3aaa22a	lavfi: search options on child objects. The child objects must be allocated and inited in the preinit() callback.	7 years ago
Nicolas George	f8d7b5febb	lavfi: add a preinit callback to filters. It is necessary for filters with child objects, to set the class and default options values.	7 years ago
Nicolas George	b77f041dff	lavfi: make FFERROR_NOT_READY available to filters. I am not entirely sure that this return code is useful, but having and using it makes no harm.	8 years ago
Muhammad Faiz	fc3a03fcf9	avfilter: take_samples: do not directly return frame when samples are skipped Modifying data pointer when skipping samples may make it unaligned. Workaround for Ticket6349. This should fix the crash of ticket's testcase and a crash/regression with avxsynth (reported by Michael Niedermayer). Also change frame->nb_samples < max to frame->nb_samples <= max. This improves performance.

Nicolas George	383057f8e7	lavfi: make ff_framequeue_skip_samples() more useful. 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>	8 years ago

Nicolas George	28c62df672	lavfi: implement ff_inlink_make_frame_writable(). 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.	8 years ago

Nicolas George	ff8b17c998	lavfi: take_samples: free frames after taking all samples.	8 years ago
Nicolas George	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.	8 years ago
Marton Balint	265d45183b	avfilter/avfilter: fix filtering frames with unknown channel layouts for filters needing writable frames Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Marton Balint <cus@passwd.hu>	8 years ago
Nicolas George	183ce55b0d	lavfi: split frame_count between input and output. 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.	8 years ago
