yes thats it thank you samuel!
the problem i am having now is if any of the sources are unavailable
then i would expect the gstreamer to fail and the fallback to kick in.
this doesnt happen though the whole .liq just hangs and the process
needs kill -9 PID
gst = input.gstreamer.audio(pipeline="uridecodebin
uri=mms://live1.rte.ie/wmtencoder/lyBREAKMEric.wma")
if i do a gst = fallback([gst,single("some.wav")])
then it fails because the gst isn’t an active source
how do i make input.gstreamer.audio an active source?
so at least the code will run and fail and fallback to the some.wav?
now i always get something like:
this value has type
source(_)
but it should be a subtype of (the type of the value at line 7, char 18)
active_source(_) (infered at line 6, char 27-95)
thanks
