I'm at nearly the same point, but I'm getting a couple of strange messages:
# media-ctl -r -l '"tvp5150m1 2-005c":0->"OMAP3 ISP CCDC":0[1], "OMAP3 ISP CCDC":1->"OMAP3 ISP CCDC output":0[1]'

What does 'Format set: unknown 720x480' mean from media-ctl?
Why 'Unable to start streaming: 32' - is this an EPIPE error?
