It means nothing, just a random error message. What is most likely
happening is that "open" failed. And what is even more likely is
permission denied, or busy. On Android, you should use Android API.
Opening V4L2 device directly is not part of the public API. There is
pending patches (that requires some work) to do so in GStreamer.
