Detailed Description

Input stream structure.

Member Data Documentation

sync

unsigned FFFrameSyncIn::sync

Synchronization level: frames on input at the highest sync level will generate output frame events.

For example, if inputs #0 and #1 have sync level 2 and input #2 has sync level 1, then a frame on either input #0 or #1 will generate a frame event, but not a frame on input #2 until both inputs #0 and #1 have reached EOF.

If sync is 0, no frame event will be generated.
