Hello.I don't know if this was reported or not but is a very weird
situation.I have two buttons to start an AudioPublisher and an
WebcamPublisher.In those methods if the button is
selected i publish or stop. On first time everything works properly, I
can start microphone alone, start camera alone, stop both. After I stop
the camera and try to start the microphone again I receive two null
errors from WebcamPublisher, not from AudioPublisher. This is weird,
there are any connections between webcam...
