libraw1394-11 2.1.2-1 (arm64 binary) in ubuntu focal

 libraw1394 is the only supported interface to the kernel side raw1394
 of the Linux IEEE-1394 subsystem, which provides direct access to the
 connected 1394 buses to user space. Through libraw1394/raw1394,
 applications can directly send to and receive from other nodes without
 requiring a kernel driver for the protocol in question.
