Before installing this, +"removepkg jack2" if you had it installed. + +SBo build maintainers, please list jack (not jack1) as a dependency for +your builds.

The old 0.125.0 version (formerly jack-audio-connection-kit) +is still available as "jack1". The JACK2 build used to be called "jack2", +and has been renamed to simply "jack". SBo maintainers take note: please +don't list jack1 in REQUIRES for your builds. If your build really does +work only with jack1 and fails with jack, please contact me (B. Watson, +yalhcru@gmail.com) and let me know the details. + +This information might be helpful in understanding the differences +between jack and jack1. + +jack and jack1 are API compatible enough that applications can be built +against either, and in fact most (possibly all?) apps can be built +against one and run with the other with no problems. + +jack1 wasn't designed to benefit from multiple CPU cores/threads. It may +(or may not) offer slightly better performance on single-core systems. + +jack no longer supports jack1's "-Z" flag. + +When using -Xseq with jack, connect your ALSA MIDI devices to the system +"MIDI thru" port, then connect that port to the JACK midi capture +port. This is an extra step that isn't necessary with jack1. + +jack stores a persistent "registry" and database in /dev/shm, which +is intended to speed up jack startup and allow multiple jack servers +on the same host to cooperate. There is one small issue with this: +if jackd can't write to /dev/shm/jack_db/, it will fail to start +(segfault). If this happens, make sure jackd is not running, and "rm +-rf /dev/shm/jack*". This only happens when jackd is used by different +users, which means most of us will be unaffected by it. Upstream has +been notified, and a fix is being worked on. + +Original README from the old jack2 package has some possibly outdated +info on the differences between 1 and 2: + +jackdmp (aka JACK2) is a C++ version of the JACK low-latency audio +server for multi-processor machines. 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..44b2180da1 --- /dev/null +++ b/audio/jack/setcap.sh @@ -0,0 +1,16 @@ +if [ -x /sbin/setcap ]; then + bin=( + jackdbus jack_monitor_client jack_latent_client alsa_in + jack_midi_dump jack_showtime jack_rec jack_zombie jack_midiseq + jack_thru jack_connect jack_net_slave jack_bufsize jack_wait + alsa_out jack_freewheel jack_server_control jack_net_master + jack_evmon jack_metro jack_simple_client jack_lsp jack_cpu + jack_control jack_netsource jack_test jack_session_notify + jack_alias jack_iodelay jackd jack_simple_session_client + jack_midisine jack_unload jack_load jack_samplerate + jack_midi_latency_test jack_cpu_load jack_multiple_metro) + + for i in ${bin[@]}; do + /sbin/setcap cap_ipc_lock,cap_sys_nice=ep usr/bin/$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.
