That is why I check the return the state of the set_state method and if it returns STATE_CHANGE_ASYNC I do a get_state which waits for the state change to actually finish. But no matter how high I set the timeout of the get_state method it still returns STATE_CHANGE_ASYNC which means the state change still isn't finished. >> After putting the stream to the READY status I can't put it into the >> PLAYING status again.
