libiec61883-0 1.2.0-3 (s390x binary) in ubuntu focal

 Implementation of IEC 61883, part 1 (CIP, plug registers, and CMP), part 2
 (DV-SD), part 4 (MPEG2-TS), and part 6 (AMDTP). Outside of IIDC, nearly all
 FireWire multimedia devices use IEC 61883 protocols.
 .
 The libiec61883 library provides a higher level API for streaming DV,
 MPEG-2 and audio over Linux IEEE 1394. This includes both reception and
 transmission. It uses the new "rawiso" API of libraw1394, which
 transparently provides mmap-ed DMA for efficient data transfer. It also
 represents the third generation of I/O technology for Linux 1394 for
 these media types thereby removing the complexities of additional kernel
 modules, /dev nodes, and procfs. It also consolidates features for plug
 control registers and connection management that previously existed in
 experimental form in an unreleased version of libavc1394.
