pychromecast: More Documentation Needed to Avoid RunTime errors

Suppose I have a cast cast and have already called cast.wait() Subsequent cast.wait()'s result in RunTimeError’s if the thread has already been run and if these errors do occur, then the self.status_event.wait(timeout=timeout) never happens. This is what I suspect indirectly causes my NotConnected errors when I try to set_volume afterwards.

I will test if the below fixes the problem for me, but before updating pychromecast by 2 years worth of code, no RunTimeError’s were being raised by cast.wait(). (EDIT: it does not fix the underlying problem).

def cast_wait():
    try:
        cast.wait(timeout=WAIT_TIMEOUT)
    except AttributeError:
        pass
    except RuntimeError:
        cast.status_event.wait(WAIT_TIMEOUT)
