Hi lista :)
Using an i3 <https://i3wm.org/docs/userguide.html#exec> shortcut, I can
control my jack transport from everywhere, even when no jack application
has focus :
bindsym $mod+p exec echo play | jack_transport
bindsym $mod+Shift+p exec echo stop | jack_transport
Thanks to FalkTX for the pipe trick BTW, I saw that on linuxmusicians ;
This is very cool if you have some sort of wireless keyboard, but as you
can see it's two different keystrokes, how do I make it so <command>
toggles play/pause? Alternatively, how do I know when jack transport is
rolling, so I can hack my way into making my own toggle script? I did my
homework and read the inline --help of all the available jack commands
on my machine :
⚡ jack_
jack_alias jack_freewheel jack_monitor_client
jack_simple_client
jack_bufsize jack_iodelay jack_multiple_metro
jack_simple_session_client
jack_capture jack_latent_client
jack_net_master jack_test
jack_capture_gui jack_load jack_net_slave jack_thru
jack_connect jack_lsp jack_netsource
jack_transport
jack_control jack_metro jack_rec
jack_unload
jack_cpu jack_midi_dump jack_samplerate
jack_wait
jack_cpu_load jack_midi_latency_test
jack_server_control jack_zombie
jack_disconnect jack_midiseq jack_session_notify
jack_evmon jack_midisine jack_showtime
But found no way to detect the transport status ; Is there a way to know
it?

AFAICS, even libjack only provides functions to start/stop the transport
or get/set the current frame.
Unfortunately, the Jack2 DBUS interface does not seem to export access
to this functionality at all:
https://github.com/jackaudio/jack2/blob/364159f8212393442670b9c3b68b75aa39d…
You could write your own minimal JACK client to query the transport
frame and check again a few milliseconds later to determine whether the
transport is running.
Using the jacklib.py module included in Cadence (and which I borrowed
for jack-matchmaker[1]), this is very easy to do in Python:

Do you have access to the jack tools package? I have a group of commands
that are jack-* as well as those above. jack-transport looks like this on
screen:
jack-transport
# 00:00:07
[s]tart,[s]top,[f]orward,[b]ack,[l]ocate,[i]ncrement,[z]ero,[q]uit
The "s" in start/stop is "space", you can tell which by watching the
time... if it is moving space will stop. Also the # means stopped and will
be replaced by a > for play

I use this very hacky script that I bind to my Play media key (I use
openbox for this):
---
#!/bin/bash
function jack_transport_status() {
jack_showtime | head -n1 & &> /dev/null
}
if jack_transport_status | grep -q -i stopped
then
echo play | jack_transport &> /dev/null
killall jack_showtime
else
echo stop | jack_transport &> /dev/null
killall jack_showtime
fi

I named it jack_start_transport. Maybe it can point you in the right
direction. I assume there are better ways to do this and this script
probably isn't the best showcase of how to script these kind of things ;)

Ok great. And yes it's hacky and contains Bashism of which &> is one of
them. I stopped using those and returned to good ol' 2>&1. Wrt not

Well, I showed you a comfortingly non-hacky solution. But if you want

Thanks guys,
I was just browsing the list for nice Linux Audio music when I found
this thread, which is just what I needed as well :)
In my case the purpose is for screencasts.
I plan to record the screen using SimpleScreenRecorder and audio
through jack into Ardour or somesuch. The problem I had was that if I
start SSR and Ardour separately I need to manually align A/V later. It
is simpler if A/V starts at the same time.
I was thinking of starting jack transport through qjackctl or somesuch,
using the CLI did not occur to me.
SSR lacks jack transport control, but I think assigning the same hotkey
to SSR and jack transport should work just fine. I guess I still need
to take the alsa/jacks latency into account, but at least that should
be small and constant.
Does anyone have a better idea?
@Holger: Thanks, but patching a jack example client requires
maintenance since this change would be lost with each new jack package
coming through the repo.

I know, I know...
that's why I wanted to send it to the Jack list to get it applied...
I still did not do it sorry. Will try to send it this evening...

Hey,
no need to say sorry. Thanks for writing the patch.
If it gets applied it will make such scripts simpler in the future.

I made a pull request yesterday evening and Stéphane has already
merged it. When it's released, toggling play state will be that easy:
echo toggle | jack_transport >/dev/null 2>&1

Thanks Holger!
In the meantime I used the hacky script successfully.
Super+J i3 shortcut that calls the script.
Super+J shortcut for SSR.
Ardour4 set to keep recording enabled and slaved to jack. Presto! A
hack on top of a hack, but it sort of works.
Jack-transport enabled SSR or somesuch would obviously be way better.

Philipp
Does anyone
have a better idea?
@Holger: Thanks, but patching a jack example client requires
maintenance since this change would be lost with each new jack
package coming through the repo.
Regards,
Philipp

This is slightly OT, because the issue seems to be with i3. Since some
of you have the same setup, I hope you can help me.
I have used this script for a while and ran into a weird problem.
Considering you have pretty much the same setup, maybe you can help me
solve it.
My setup is Arch Linux with i3.
This is how I have configured it.
bindsym $mod+j exec --no-startup-id ~/jack_transport_toggle.sh
The script as such works fine when called from a terminal.
However, the actual shortcut does not work unless I reload the i3
config.
Same result with the absolute path. I found some people on the net with
this kind of problem, but no solution. Any ideas?

How about you redirect the stdout and stderr output from/within that
jack_transport_toggle.sh script into a file to see what's happening when
you call it from the i3 shortcut?

Thanks,
while that did not help, enabling i3 logging did. It showed me that I
did not have permission. I did 'chmod +x' for the script and now it
works.
Why it did not work when i3 was started through startx but did work
after it was restarted beats me.
Anyway, I have done a number of videos with this hack (one shortcut
for SSR and jack transport) and it works well. The start of video and
audio matches up well enough for a typical screen capture.
I would still prefer something more accurate, like a screen capture
program that listens to jack transport.
