Mark Thompson	07a844f32e	lavfi: generic hardware surface upload and download filters Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Anton Khirnov	b3dd30db0b	lavfi: pass the hw frames context through the filter chain	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	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
Matthieu Bouron	0c59d40ae0	lavfi: use a video frame pool for each link of the filtergraph	9 years ago
Nicolas George	48ff6683ba	lavfi: add a frame_rate field to AVFilterLink. (cherry picked from ffmpeg commit `7b42036b3b`) Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Timothy Gu	87d5509261	avfilter: Reindent	9 years ago
Michael Niedermayer	377883c4be	avfilter/avfilter: Error out if audio parameters change instead of failing an assert Filters which support such changes should be excluded from these checks Fixes Ticket4884 Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Nicolas George	44f660e7e7	lavfi: remove FF_LINK_FLAG_REQUEST_LOOP. It has no longer any effect.	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
Michael Niedermayer	5d859e5980	avfilter/avfilter: Add a few more basic filters to the list which support frame size changes Fixes assertion failures Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Michael Niedermayer	3dfc5f551f	avfilter: avoid testing float == 0 This fixes the hypothetical case of rounding errors causing incorrect values to be used. We do not use _EPSILON, because non trivial expressions can contain errors larger than that making a zero equality test with _EPSILON unreliable.
