|Summary: Library implementing IEC 61883|
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.
* Sat Nov 14 2015 email@example.com - Use new homepage URL, URL for source archive location, and do gpgkey verification. Set RPM groups to more appropriate values. - Heed shared library packaging guideline, spell out license differences. - Remove unused --with-pic; we build no static libs, and the shared library always gets it implicitly anyway. - Name the utility package -tools as with many other pkgs. * Wed Jan 02 2013 firstname.lastname@example.org - Fix a typo mistake on devel Requires package * Sat Dec 29 2012 email@example.com - Update to 1.2.0 version: * Behavior changes of the backend to firewire-core: - The isochronous reception buffer is now mapped read/writable rather than read-only. The raw1394 backend already maps the buffer read/writable too. Note that writing into the buffer will go wrong on architectures without cache-coherent DMA if the CPU and the OHCI write within the same cacheline region, so use this feature with caution. - Decrease memory footprint of IR and IT buffers by avoiding some internal rounding up of the buffer size. * New APIs in <libraw1394/raw1394.h>: - raw1394_add_config_rom_descriptor(): - Add contents to the Configuration ROM of the local node(s). At runtime, this API is only available if running on top of firewire-core. It could probably also be implemented with the raw1394 kernel driver if anybody cared. - raw1394_remove_config_rom_descriptor(): - Counterpart to raw1394_add_config_rom_descriptor(). - raw1394_read_cycle_timer_and_clock(): - Like the existing raw1394_read_cycle_timer(), but lets the caller choose between CLOCK_REALTIME (which the former call is always using), CLOCK_MONOTONIC, or CLOCK_MONOTONIC_RAW. For example, this enables libffado's audio streaming to run undisturbed by resets of CLOCK_REALTIME. At runtime, this call requires firewire-core underneath. - raw1394_get_speed(): - Returns the speed code of the maximum possible transmission speed between a given node and the local node. This takes maximum speeds of all participating PHYs and the two links into account. This can be used to configure the speed of isochronous streams. - At runtime, this call requires firewire-core underneath. - enum raw1394_iso_speed was extended by RAW1394_ISO_SPEED_800, _1600, and _3200. * New APIs in <libraw1394/ieee1394.h>: - Added preprocessor constants L1394_SPEED_BETA, L1394_SPEED_800, _1600, and _3200. * testlibraw1394: - Added unit tests of the new APIs. - Removed patchs: fixed on upstream release: * libiec61883-1.1.0-lfs.patch * Sat Nov 19 2011 firstname.lastname@example.org - remove source URL, which is no longer valid * Sat Nov 19 2011 email@example.com - add libtool as buildrequire to avoid implicit dependency * Fri Dec 18 2009 firstname.lastname@example.org - add baselibs.conf as a source * Fri Sep 12 2008 email@example.com - remove "la" files and static libraries - use AC_SYS_LARGEFILE to detect the need of _FILE_OFFSET_BITS=64 * Thu Apr 10 2008 firstname.lastname@example.org - added baselibs.conf file to build xxbit packages for multilib support * Sun Jan 27 2008 email@example.com - Do not install libtool wrapper. * Tue Jan 30 2007 firstname.lastname@example.org - fixed dependencies, support files > 2GB.
