Referenced by ff_framesync_add_frame(), ff_framesync_get_frame(), ff_framesync_next(), framesync_advance(), and framesync_inject_frame().

uint8_t FFFrameSyncIn::state

State: before first, in stream or after EOF, for internal use.

Definition at line 133 of file framesync.h.

Referenced by framesync_advance(), framesync_inject_frame(), and framesync_sync_level_update().

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.
