Ignorant here. Trying to scrounge around and make
something work for a

purpose.
In python I am trying to build this pipeline:
pipeline_txt = (
'jackaudiosrc ! '
'level name=level interval=1000000000 !'
'jackaudiosink')
pipeline = gst.parse_launch(pipeline_txt)
I have been trying that a number of ways.
So, I basically watch the bus for level info.
In a subroutine, I can print the peak info to the terminal.
I can't seem to figure out how to pass this info back to the rest of the
program so that I can hook it up to a graphical meter.
Add a call to the callback for the meter to set the meter value from the
subroutine?
Cna anyone point me to some simple code doing
something like this? Give me
some clues that might help someone who seems to be being very dense for
days
now?
Sounds like you just need to connect the meter to the subroutine but it's
a bit had to say without a bit more code to demonstrate how you are
setting up the meter.
A few questions...
Is the meter a class of it's own or just a widget in a draw routine?
Do you have a "set_meter_value" type of function or are you just calling
directly to the meter widget's value?
What UI toolkit is the meter using?
