* lavfi: drop the requirement that request_frame returns a frame.Nicolas George2015-09-20
| | | | | | | | 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.

* lavfi: drop planar/packed negotiation supportStefano Sabatini2012-05-16
| | | | | | | | | The planar/packed switch and the packing_formats list is no longer required, since the planar/packed information is now stored in the sample format enum. This is technically a major API break, possibly it should be not too painful as we marked the audio filtering API as unstable.
