The codec is referred to as DCA in other parts of libav.

When a client behind a NAT issues a pause command, and stay paused for a
long time, the router may stop the RTP/RTCP port redirection. Resend the
hole punching packets before each PLAY command to cause the router to
restart the port redirection in that case.

Move the existing code for sending the packets from the SETUP phase
to the PLAY phase.

Since not all systems need the libraw1394 dependency, let pkg-config
provide the list of libraries actually needed.

The libdc1394-2.pc file has been included since version 2 (2008-01-05),
so it should be safe to use.

When receiving an RTCP packet, the difference between the last RTCP
timestamp and the base timestamp may be negative. As these timestamps
are of the uint32_t type, the result becomes a large integer. Cast
the difference to int32_t to avoid this issue.

The result of this issue is very large start times for RTSP
streams, and difficulty to restart correctly after a pause.

This prevents using a wrong (first thread's) AVCodecContext if decoding
a frame in the first pass over all threads fails.

It may be empty if the previous thread's decode call did not contain a
valid frame.
