Hi Alex,

Did manage to get to the bottom of this? I'm seeing the same thing with
raspivid / raspistill (although mjpg-streamer works fine).

mmal: mmal_vc_component_create: failed to create component 'vc.ril.camera'

- My checkout of meta-raspberrypi is current on f3a8693f (Andrei
Gherzan, May 8th) so I don't believe this is an out of date firmware
issue (?)

- I tried disabling the preview screen in case there was some kind of
video overlay issue

e.g. raspivid -n -w 640 -h 480 -fps 5

- I'm not seeing ENOMEM as the error and my GPU_MEM = "128" which I've
checked translates into the correct setting in config.txt in the boot
partition

- I read that it could possibly be related to current consumption and
the polyfuse, so I'm now powering from a bench PSU direct into the P1
header, and current limiting isn't the issue.

- I've just put a downloaded and put copy of Raspbian on there.  Running
raspivid seems to work fine (preview screen etc. etc.)

e.g. raspivid -w 640 -h 480 -fps 5

- Looking at the raspivid source it seems a fairly straightforward setup
call is failing early on, leading me to think something is missing as
you suggest?
