This library is an 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.
