JACK also has support for +distributing audio processing across a network, both fast & reliable +LANs as well as slower, less reliable WANs. + +This package includes both jack and jack-example-tools. + +Note: This build conflicts with jack1: install only one of the two. +JACK's developers recommend not using jack1 at all, although it's still +maintained. + +Note: this build was formerly known as jack2. Before installing this, +"removepkg jack2" if you had it installed. + +SBo build maintainers, please list jack (not jack1) as a dependency for +your builds. If the software you're trying to build really does work +with jack1 but not jack, please contact the jack maintainer (currently +B. Watson <urchlay@slackware.uk>. Include the build log and any runtime +error messages in your email, plase. + +This package uses POSIX filesystem capabilities to execute with +elevated privileges (required for realtime audio processing).

It is a new implementation +of the JACK server core features that aims in removing some +limitations of the JACK1 design. The activation system has been +changed for a data flow model and lock-free programming techniques +for graph access have been used to have a more dynamic and +robust system. + +- jackdmp use a new client activation model that allows simultaneous +client execution (on a smp machine) when parallel clients exist +in the graph (client that have the same inputs). This activation model +allows to better use available CPU on a smp machine, but also works +on a mono-processor machine. + +- jackdmp use a lock-free way to access (read/write) the client graph, +thus allowing connections/disconnection to be done without +interrupting the audio stream. The result is that +connections/disconnections are glitch-free. + +- jackdmp can work in 2 different modes at the server level : + - synchronous activation : in a given cycle, the server waits for + all clients to be finished (similar to normal jackd) + - asynchronous activation : in a given cycle, the server does not + wait for all clients to be finished and use output buffer + computed the previous cycle. + +The audible result of this mode is that if a client is not activated +during one cycle, other clients may still run and the resulting audio +stream will still be produced (even if its partial in some way). +This mode usually result in fewer (less audible) audio glitches in a +loaded system. diff --git a/audio/jack/setcap.sh b/audio/jack/setcap.sh new file mode 100644 index 0000000000..4a3331efd0 --- /dev/null +++ b/audio/jack/setcap.sh @@ -0,0 +1,5 @@ +if [ -x /sbin/setcap ]; then + for i in @BINS@; do + /sbin/setcap cap_ipc_lock,cap_sys_nice=ep usr/bin/$i + done +fi diff --git a/audio/jack/slack-desc b/audio/jack/slack-desc new file mode 100644 index 0000000000..ee8df1b978 --- /dev/null +++ b/audio/jack/slack-desc @@ -0,0 +1,19 @@ +# HOW TO EDIT THIS FILE: +# The "handy ruler" below makes it easier to edit a package description. +# Line up the first '|' above the ':' following the base package name, and +# the '|' on the right side marks the last column you can put a character in. +# You must make exactly 11 lines for the formatting to be correct.
