Protocol

FxTemporalImageAPI

The FxTemporalImageAPI protocol defines the methods the host application provides to access an input image at a specific time.

Declaration

@protocol FxTemporalImageAPI

Overview

The only plug-in that needs to use this host application protocol is an FxFilter that does "retiming," that is a filter whose output depends on input frames at times other than the output time.
