frame_blocked_in

int FilterLinkInternal::frame_blocked_in

If set, the source filter can not generate a frame as is.

The goal is to avoid repeatedly calling the request_frame() method on the same link.

status_in

int FilterLinkInternal::status_in

Link input status.

If not zero, all attempts of filter_frame will fail with the corresponding code.

status_in_pts

int64_t FilterLinkInternal::status_in_pts

Timestamp of the input status change.

Definition at line 60 of file avfilter_internal.h.

status_out

int FilterLinkInternal::status_out

Link output status.

If not zero, all attempts of request_frame will fail with the corresponding code.

Definition at line 67 of file avfilter_internal.h.

age_index

int FilterLinkInternal::age_index

Index in the age array.

init_state

enum { ... } FilterLinkInternal::init_state

stage of the initialization of the link properties (dimensions, etc)
