Unfortunately it doesn't.
Kevin, Ronan: Olivier is using the current "tizen" branch of
tizen-distro, which is essentially rev_0.9. Do you have any idea why
this worked when you tried it?

You can just edit /etc/groups directly. The fix in the recipes is in
config-tizen-ivi.bb: adding the "app" user must include the "video"
group.
Same question here: how can this have worked when rev_0.9 was released?
I've fixed the group permissions locally; unfortunately now weston
segfaults in gl-renderer.so, with and without "security=none".
