[Jack-Devel] About cross-compilation of jack2 in MXE and libportaudio

by Harry Nakos

Hi, guys! I recently committed the entry for jack2 to the MXE cross-compiler, specifically version 1.9.10. One notable thing was needed and that was linking to flac, vorbis, vorbisenc, and ogg, dependencies that libsndfile had (needed for static linking). Timothy Gu of MXE suggested that a recent commit in jack2 utilised pkg-config for libsndfile and that would eliminate the need of my not-so-pretty hack. Anyway, this is not the main reason for this message. But any general points about cross-compilation of jack2 and required/suggested libraries would be nice. The main reason is portaudio. After building jack2 in MXE, I saw this in my log: + install /home/xnakos/Projects/mxe/usr/i686-w64-mingw32.shared/lib/libportaudio.dll.a (from build/windows/libportaudio.dll.a) This resulted in portaudio library, which was already built in MXE as a requirement for jack2, to be overwritten. I am not quite sure I understand the reasons for this. So I would really enjoy an explanation! In practice, when trying to cross-compile Hydrogen drum machine, this overwrite would result in linking errors such as: CMakeFiles/hydrogen-core-0.9.7.dir/objects.a(portaudio_driver.cpp.obj): In function `ZN6H2Core15PortAudioDriver10disconnectEv': portaudio_driver.cpp:107: undefined reference to `Pa_StopStream' portaudio_driver.cpp:114: undefined reference to `Pa_CloseStream' portaudio_driver.cpp:121: undefined reference to `Pa_Terminate' portaudio_driver.cpp:111: undefined reference to `Pa_GetErrorText' portaudio_driver.cpp:118: undefined reference to `Pa_GetErrorText' CMakeFiles/hydrogen-core-0.9.7.dir/objects.a(portaudio_driver.cpp.obj): In function `ZN6H2Core15PortAudioDriver7connectEv': portaudio_driver.cpp:71: undefined reference to `Pa_Initialize' portaudio_driver.cpp:75: undefined reference to `Pa_GetErrorText' portaudio_driver.cpp:87: undefined reference to `Pa_OpenDefaultStream' portaudio_driver.cpp:91: undefined reference to `Pa_GetErrorText' portaudio_driver.cpp:95: undefined reference to `Pa_StartStream' portaudio_driver.cpp:99: undefined reference to `Pa_GetErrorText' These errors are not present when linking to the original portaudio library. Any information would be great, because I am definitely missing a lot. Harry

[Jack-Devel] 64 bit jack applications compiled with mingw crashes

by Kjetil Matheussen

Hi, I'm trying to compile a 64 bit jack application (radium) with mingw-64. When I compile it in 32 bit mode, it works fine, but when creating a 64 bit version, it crashes when calling a jack_* function. The same happens when trying to run a simple test program: " #include <jack/jack.h> int main(){ jack_ringbuffer_create(8000); // (Also crashes if callling jack_client_open) return 0; } " If I compile it like this (32 bit): $ i686-w64-mingw32-gcc winjacktest.c -I/home/kjetil/.wine/drive_c/Program\ Files/Jack/includes /home/kjetil/.wine/drive_c/Program\ Files/Jack/lib/libjack.lib ...it works But if I compile it like this (64 bit): $ x86_64-w64-mingw32-gcc winjacktest.c -I/home/kjetil/.wine/drive_c/Program\ Files/Jack/includes /home/kjetil/.wine/drive_c/Program\ Files/Jack/lib/libjack64.lib ...it crashes. I also have a backtrace. The second last frame in the backtrace is the call to "jack_ringbuffer", while the last frame shows that an unrelated function is called instead of jack_rinbuffer_create. So it seems like either the stack itself is a little bit corrupted, or libjack64.lib sends the program further to a random place in the program instead of the libjack64.dll library. The latter might be more likely though, since it's the same backtrace every time. I've tried installed both the 32 bit and the 64 bit version of jack which are available for download at jackaudio.org. Same behaviour for both. My gcc is a little bit old, but I guess that isn't the reason for the crash: $ x86_64-w64-mingw32-gcc --version x86_64-w64-mingw32-gcc (GCC) 4.7.2 20120920 (Fedora MinGW 4.7.2-7.fc17) $ i686-w64-mingw32-gcc --version i686-w64-mingw32-gcc (GCC) 4.7.2 20120920 (Fedora MinGW 4.7.2-7.fc17) Thanks for any help. Please let me know if there's anything I should try.

[Jack-Devel] NetJack2 Transport Sync dev

by Wargreen

Hi, I work on the creation of a live music/light/video show, with electro-acoustic composition, and lot more. We need a robust synchronisation between all elements (synths and OSX / linux computers) and we want to mix and process with free softwares, so use the netjack capabilites for transport audio on a gigabyte network. According to this issue (https://github.com/jackaudio/jack2/issues/124), the transport sync it's in Work in Progress state from 2011, so if someone have knowledges and desire for work on this, we can pay some beer / food / [enter what you want here]. We don't know how many work it needed to get netjack transport sync working, and maybe it's the first step... This show it's a little self-production, so wa haven't lot of funds, but we try to do the best ! Thanks for reading, and thanks for all propositions / ideas !

[Jack-Devel] Fwd: KDE && jackd flag -l (was: kbiff && zombies)

by Matthias Apitz

Hallo, I'm an active FreeBSD user and I'm trying to nail down a problem of zombies caused by KDE components which make use of jack-audio-connection-kit-0.121.3 To get this debugged I have inserted a wrapper script as /usr/local/bin/jackd which does some logging and calls at the end the real jackd as jackd.bin (see below). I've stumbled over something in the source and man page of jackd which I do not understand: The man page explains the flag -l as for changing the LISTEN port, while the implementation in the C-source use the flag -l to just print the actual working directory (/tmp) and do exit(0); see below. Perhaps, the KDE components do not expect the termination of the forked jackd server and resulting to state zombie. Do I misunderstand something stupidly wrong?

CCed now. And the answer is no, JACK does not control application level volume, it just forwards and merges audio streams. If you want volume control, use a mixer (maybe one of not too many jack-based mixers), so you can adjust each jack client's volume in one place. HTH

[Jack-Devel] NetJack2 & transport sync

by Wargreen

Hi jack list ! I try to get transport sync via netjack2 for a live music, light and video show, and : With the "net" driver, i don't find any option for turn on the transport sync, so the slave start with "Transport sync : no" With the "netadapter" internal , the connection seem good, with "Transport sync : yes" but I got lot of errors on the slave. The log is here : http://www.phuck.ovh/wargreen/pub/logs/netjack_netadapter_1.log How to get the transport sync woking ? Thanks a lot, Wargreen

[Jack-Devel] Netjack 2: how to improve reliability by allowing greater latency?

by André Pinto

Hello, I've been playing around with Jack/Netjack and the Opus codec in order to setup a "low latency" WiFi audio stream at home. After compiling Opus with custom modes and Jack2 with Opus support (both from the master branches of the respective repositories), I was able to run the Master-Slave setup: Master. jackd -R -d alsa -d hw:1 -D=false -r44100 -S -n16 jack_load netmanager Slave: jackd -R -d net -C0 -P2 -o0 -i0 -O320 -M1200 -l5 + jack_connect to route the net input on the master to the speakers But as I was getting quite frequent audio deterioration, with the master showing messages like these: Packet(s) missing from... -1 1 Wrong packet type : a JackEngine::XRun: client = SLAVE_HOSTNAME was not finished, state = Running JackEngine::XRun: client netmanager finished after current callback JackAudioDriver::ProcessGraphAsyncMaster: Process error Wrong packet type : a Packet(s) missing from... -1 1 JackAudioDriver::ProcessGraphAsyncMaster: Process error JackEngine::XRun: client = SLAVE_HOSTNAME was not finished, state = Triggered I've thought that maybe I should just try increasing the network latency argument on the slave, as, for my use case, I'm happy with latency < 200 ms. By using something like -l30 (the maximum I'm allowed to set) on the slave I was able to greatly diminish the Process errors (I still get the same lots of wrong packet type and packet missing messages though) but it didn't fix the audio artifacts. Actually sometimes this change makes the playback even worse with ms pauses every second. So I would like to know if there is any other way to relax the low latency requirement in order to improve playback reliability. Or is there some kind of incompatibility in the configuration I'm passing to both endpoints that is causing these problems? Thanks! André.
