I under stand this a bit more. I read up on the spectrum element, but I can't
figure out how to get the messages it sends out. This is what I have now, it
does not work.
import rhythmdb, rb
> import serial
> import gst
>
> class LEDcube(rb.Plugin):
>
> def __init__(self):
> rb.Plugin.__init__(self)
>
> def activate(self, shell):
> print "activating LED cube python plugin"
> self.b = gst.element_factory_make ("spectrum")
> shell.get_player().props.player.add_tee(self.b)
> self.ser = serial.Serial('/dev/ttyS0', 115200, timeout=1)
> self.ser.write("hello")
>
> bus = gst.element_get_bus(self.b)
> bus.add_signal_watch()
> bus.connect("message", self.on_message)
>
> def deactivate(self, shell):
> print "deactivating LED cube python plugin"
> shell.get_player().props.player.remove_tee(self.b)
> self.ser.close()
>
> def on_message(self, bus, message):
> print "Spectrum!"
Is the bus stuff even remotely correct?
Thanks,
Justin
