fifo

AVContainerFifo* BitStreamFilterLinkInternal::fifo

Queue of packets waiting to be filtered.

packet_blocked_in

int BitStreamFilterLinkInternal::packet_blocked_in

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

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

status_in

int BitStreamFilterLinkInternal::status_in

Link input status.

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

status_in_pts

int64_t BitStreamFilterLinkInternal::status_in_pts

Timestamp of the input status change.

status_out

int BitStreamFilterLinkInternal::status_out

Link output status.

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

packet_wanted_out

int BitStreamFilterLinkInternal::packet_wanted_out

True if a packet is currently wanted on the output of this filter.

Set when ff_request_packet() is called by the output, cleared when a packet is filtered.
