Rostislav Pehlivanov	3796fb2692	lavfi: deprecate AVFilterGraph->resample_lavr_opts Not used by anything at all since we don't auto insert lavr filters. Reviewed-by: wm4 <nfxjfg@googlemail.com> Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	8 years ago

Matthieu Bouron	b1f68f00b1	lavfi/framepool: rename FFVideoFramePool to FFFramePool	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
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
Mark Thompson	e3fb74f7f9	lavfi: Always propagate hw_frames_ctx through links 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).	8 years ago

Timo Rothenpieler	1a75145559	lavfi: Move new field to the end of AVFilterContext This fixes an accidental ABI break introduced at `8688d3a`.	9 years ago
Timo Rothenpieler	1eb43af1a0	lavfi: Move new field to the end of AVFilterLink Even though this is not part of the public API, some external applications access fields after it, thus breaking after updating from ffmpeg 3.0 or earlier. Since it is not public, it can be freely moved to the end to avoid that problem in the future. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Paul B Mahol	547d412078	avfilter: update some comments start_frame is no more, samplesref argument is now frame argument. Signed-off-by: Paul B Mahol <onemda@gmail.com>	9 years ago
Nicolas George	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.	9 years ago
Nicolas George	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.	9 years ago
Nicolas George	39a09e995d	lavfi: deprecate avfilter_link_set_closed(). Applications are not supposed to mess with links, they should close the sinks. Furthermore, this function does not distinguish what end of the link caused the close and does not have a timestamp.	9 years ago
Nicolas George	b8b7d5ac6c	lavfi: add link.current_pts field.	9 years ago
Nicolas George	d03eab34dd	lavfi: rename link.current_pts to current_pts_us. This field is used for fast comparison between link ages, it is in AV_TIME_BASE units, in other words microseconds, µs =~ us. Renaming it allows a second field in link time base units.	9 years ago

Nicolas George	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.	9 years ago
