Perhaps not the best, but here's my stab at making it continue to work with
older kernels:
commit 06c70c2b6a9573a6c72968bce725d30d09cbfe8a

Remove usage of VPE in running TIDL examples

As I look at this, I think it would fail if there were just 2 non-vpe
interfaces.
There has to be a relatively easy way to pick the first webcam.
