* lavfi/framesync2: implement "activate" design.Nicolas George2017-07-30
| | | | | | 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.
* lavfi: add outlink helper functions.Nicolas George2017-07-30
| | | | | | These wrappers cost nothing, they make the namespace more consistent and they will be useful if/when locking becomes necessary.
* lavfi: make FFERROR_NOT_READY available to filters.Nicolas George2017-07-30
| | | | | I am not entirely sure that this return code is useful, but having and using it makes no harm.
* lavfi/framesync2: rename all conflicting symbols.Nicolas George2017-07-30
|
* lavfi: copy framesync into framesync2.Nicolas George2017-07-30
| | | | | | | 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.
* Revert "Revert "lavfi/buffersrc: push the frame deeper if requested.""Nicolas George2017-07-30
| | | | | | | | | | | This reverts commit 04aa09c4bcf2d5a634a35da3a3ae3fc1abe30ef8 and reintroduces 0ff5567a30be6d7c804e95997ae282d6bacd76c3 that was temporarily reverted due to minor regressions. It also reverts e5bce8b4ce7b1f3a83998febdfa86a3771df96ce that fixed FATE refs. The fate-ffm change is caused by field_order now being set on the output format because the first frame arrives earlier. The fate-mxf change is assumed to be the same.
