[QJACKCTL] list of available jack backends

Ciao Rui,

Another question:

Is the list of available jack backends (alsa, freebob, etc) accessible from qjackctl formed at compile time or run / init time ?

If it is formed at compile time, then distro packaged qjackctls do not detect the net backend (netjack) so it is not available from the setup window in qjackctl. Until recently, jackd's been packaged WITHOUT netjack (a real shame but fortunately, we always have the freedom to compile softs ourselves).

I am not sure if this is still the case as I use the jack svn code.

J.

the list is hardcoded in src/qjackctlSetupForm.ui

qjackctl cvs has the "net" slave backend added to the hard-coded list.

Ah, it is hardcoded ...

Do you think it would be better to form the list at init time when launching the app ?

In fact, is it possible at all ? I believe $prefix/lib/jack contains not only backends but inprocess clients, etc.

This is  (port of) what the so called "JACK2 control API" is ready  
for: gives an API to dynamically know what backend are available.

Hi Stephane,

Sounds cool! When is this control API available to jack apps ?

I think they are some discussions pending (look at some of my previous  
mails like "Server control plug-ins proposal"...), in order to decide  
what is the proper way to expose this API to  JACK apps.
