[Jack-Devel] New build of QJackCtl for Windows

by Kjetil Matheussen

Hi all, The build of qjackctl included with jackdmp for windows is getting really old. The biggest problem is that the default "startup time" is set too low, making it seem like "jack crashes". (I"ve got many complains that "jack crashes"). Another problem is that you manually have to append "-S" to the "Server Prefix". So here: https://github.com/kmatheussen/qjackctl ...I've cloned the official qjackctl repository, fixed these two problems, and added some files to make it straight forward to build qjackctl under mingw32. (Building is just running the "build_mingw32.sh" script) Windows binary: http://folk.uio.no/~ksvalast/qjackctl.zip Perhaps this build, or something similar, can be included in the next release of jack for windows?

[Jack-Devel] jack on OSX

by vic hug

Hey, I was wondering, seeing as the latest distributed compiled package (on http://jackaudio.org/downloads/) for osx is version 0.90, and it is stated as beeing for Snow Leopard ; was wondering if i should try to compile it myself from the 1.9.10 tarball (or even the git repos ?) ; because i'm not very knowledgeable in coding so i'm afraid i have no idea how to compile it. Opening the xcode project in the git repo, then trying to compile it ; leads very fast to a critical " 'aften/aften.h' file not found" error ; and i don't see a "aften" file in the distribution. In short, i do'nt know how stable is the 1.9.10 or Github version, but i'm not sure it is very wise either to use the maybe outdated 0.9 ? but for now, i don't know how i could do else... Thanks in advance, Victor

[Jack-Devel] jackd on low memory embedded systems

by Matt Flax

Hi there, I am wanting to run jackd on low resourced/power embedded systems (running Linux). When I run jackd on these systems it tries to lock down way to much memory ... much more then is available. Is the amount of memory locked down by jackd configurable ? Or is it an operating system set thing ? Does anyone have any constructive ideas or suggestions for running jackd on these low resource embedded systems ? thanks Matt

by Pawel

I send a patch once on this list and this is a "patched" version. I keep this, because it was very helpfull while testing and improve other apps ( like hydrogen , fsthost ), especially tempo change issues. Not perfect but better than "official", especially in low tempos ( like 30 BPM ). .. so yes you are inconvincible ;-) P.

Hi, Tobias, you can check my slightly improved version of jack_transport: https://sourceforge.net/p/nxjsm/code/HEAD/tree/trunk/tools/transport.c I'm also the author of new Hydrogen jack-master code. It's works much better , but probably not perfect ;-) P.

[Jack-Devel] jack1: jack_transport does not work as master

by Tobias Hoffmann

Hi, I'm still using debian's jackd1/libjack0 package (0.124.1) and have not tried to reproduce this with git master yet (at least, I haven't seen an obvious fix in the commit log since 0.124.1). In one terminal window I run jack_showtime. In the other window I do: jack_transport > tempo 96 # just in case > master > play # does not jack_showtime correctly shows the state, but no BBT information. From my own client I know that jack_position_t::valid==0. Some testing revealed that the timebase() callback in tools/transport.c is *not called at all*, although jack_set_timebase_callback is called and returns without error. - But everything works fine when I switch to the jack2 stack... And in some cases, when switching between/enabling/disabling different Transport masters, jack_position_t::valid retains the JackPositionBBT flag (and stale information) -- but no-one updates them any more... Maybe related: I've seen some strange values (*very* large negative number) for bar_start_tick when using ardour4.1. The very first time (and after rewind?) it contains 0.0 and is not updated. A quick glance into the ardour source code reveals that this field is not implemented yet. I could probably live with that. BUT: After stopping+starting the playback, these strange values appear... How can I know whether some value in this field is usable at all -- except for some heuristics? Back to the original topic... in both cases the jack_position_t struct contains stale/random values, instead of starting from a "clean" base -- maybe memset(,0,) is all that is needed here? Tobias
