Eval JACK trouble

[Julien Claassen]

Hello!
   I just downloaded jack from svn and I get the following problem:
mplayer *.wav (all is well)
jack_lsp -c shows mplayers' ports being connected to system_playback_* ports.
linuxsampler
(load some instrument and setup audio engine channels)
jack_lsp shows:
LinuxSampler:0
LinuxSampler:1
jack_connect LinuxSampler:0 system:playback_1
engine sample rate: 48000
cannot connect ports
   Jack server says:
destination port in attempted connection of system:playback_1 and
LinuxSampler:0
  is not an input port

   What is going on here. Jack says it's Version 0.112.0.
   Can anybody enlighten me/help me here?
   Kindest regards
         Julien

Hi

same here, I found the last working jack_connect tool in revision 2284 (
0-111-5). This one work also with jackd 0.112.0. The related changes are :

  return 1;
  }
I change this lines back to version  0-111-5 and jack_connect work. BUT THIS
IS NO SOLUTION, BECAUSE JACK CRASHED SOMETIMES WITH THIS VERSION OF
jack_connect.

hope it bring's a little light in this.

Hello Hermann!
   Thanks for the answer. I just wondered about the logic of it all. It goes
like this:
first check first argument or one before last
   (which is OK for an input_port)
Then check second argument or two before last
   (Why two before last, should it be last, so the possible succession is:
jack_connect in_port out_port
or:
jack_connect [options] in_port out_port
   But that way the second form would be:
jack_connect [options] out_port in_port [one other option]
   I just wonder...
   Btw.: I think this is not good at all, at least when I see it as it is
there. Because:
if (first two argv[]s no options)
   if in_port in argv[1]
   if out_port in argv[2]
else // first one is an option
   if in_port in argv[argc-1]
   if out_port in argv[argc]
// end else
   Kindest regards
         Julien

Hi everyone!
   I fixed the connect.c from jack 0.112.0. It was mainly some confusing inputs
with outputs and forgetting a return statement.
   Whom to send the file now?
   Kindest regards
         Julien

Hi Julien

Thanks for submit ! It works for me.
Paul Davis is a member of this list, so he will read it soner or later. I
remember that I read a Post from him at jack-devel where he ask for testing
to bring out a new release. So it will be good to fix jack_connect in svn.
I diff your version against the fresh svn outcheck :

Hi Julien

Today I make a fresh outcheck from jack svn(0.112.1), I found the jack_connect
tool working again without a change in the source, but it have turn the
ports. jack_connect work now like that
jack_connect system:playback_1 system:capture_3
for example, that is contra to the bash completion wich will indicate a
inputport at first argument.
