lang=EN-US style='font-size:12.0pt'>The first command will run the camera data
directly to the xv image sink via gstreamer (a video application framework used
by the Record activity). We can diagnose where the problem is better when
we see the result of this test. <br>
<br>
The second command will run a test pattern directly to the xv image sink.
If we get the same visual problem with the test patter, we might be able to
rule out the camera as the culprit.<br>
