* | lavfi: guess a timestamp for compat status change.Nicolas George2017-09-08
| | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | It is necessary for filters with child objects, to set the class and default options values.

* | avfilter: take_samples: do not directly return frame when samples are skippedMuhammad Faiz2017-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * 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 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>

| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: split frame_count between input and output.Nicolas George2016-11-13
| | | | | | | | | | | | | | | | | | | | | | | | 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.
