Niklas Haas	a5032dc12a	avfilter/framesync: make framesync_class un-static And rename to ff_framesync_class. More convenient for downstream users.	8 months ago
Anton Khirnov	08bebeb1be	Revert "all: Don't set AVClass.item_name to its default value" Some callers assume that item_name is always set, so this may be considered an API break. This reverts commit `0c6203c97a`.	11 months ago
Andreas Rheinhardt	0c6203c97a	all: Don't set AVClass.item_name to its default value Unnecessary since acf63d5350adeae551d412db699f8ca03f7e76b9; also avoids relocations. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	1 year ago
James Almer	0c3e3fd1b4	avfilter/framesync: add a new option to set how to sync streams based on secondary input timestamps Include two values for it, a default one that sets/keeps the current behavior, where the frame event generated by the primary input will have a timestamp equal or higher than frames in secondary input, plus a new one where the secondary input frame will be that with the absolute closest timestamp to that of the frame event one. Addresses ticket #9689, where the new optional behavior produces better frame syncronization. Reviewed-by: Nicolas George <george@nsup.org> Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago
Andreas Rheinhardt	d6f4b91ba5	avfilter/framesync: Remove redundant setting of AVClass Every filter exposing the framesync options via its child_next callback already calls framesync_preinit() in its preinit callback. So the filter is already preinited whenever its child_next is called. Reviewed-by: Nicolas George <george@nsup.org> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago

Nicolas George	05a23b2565	lavfi/framesync2: add common options. Also add functions and macros to help filters chaining these options to their own.	7 years ago
Nicolas George	0ae8df4109	lavfi/framesync2: add dualinput helper functions.	7 years ago
Nicolas George	4e0e9ce2dc	lavfi/framesync2: implement "activate" design. With this helper API, filters that used the first framesync helper API can easily be changed to use the new and more extensible design for filters with a single activate() callback.	8 years ago
Nicolas George	873306f265	lavfi/framesync2: rename all conflicting symbols.	8 years ago
Nicolas George	cffea1b483	lavfi: copy framesync into framesync2. framesync2 will be the base for the version using activate. Most of the logic will be the same, but the code cannot be shared. Copying the file initially without change will make the diff easier to read.	8 years ago

Nicolas George	53319d5c93	lavfi: add an API to synchronize multiple video inputs. Compared to dualinput, this API can handle more than two inputs and can generate frames synchronized to any or all input streams.	11 years ago
