Research direction
Start by reproducing the issue with the documented gst-launch-0.10 videotestsrc pipeline on the Beagleboard C4 and compare the first and second runs. Trace the TIDmaiVideoSink and omapfb display path using the full console output; done means the test video runs without “display not found,” a black monitor, or “Unable to apply changes.”
