Hi Hans,
Thanks for your inputs.We are part of Linaro organisation For more
details on Linaro please refer to http://www.linaro.org . As part of our
activities on Linaro we have been debating at whats the right solution for
exposing camera support / features on a platform Openmax or v4l2.

Looking at ppt from Robert , it seems v4l2 subdevices is the way to support
different devices that may be involved in imaging processing chain, also
from the ppt it seems a userside library for Media controller is needed
particular to each platform which controls these subdevices.I have not been

In the reference architecture in ppt, we can directly wait for the RSZ
interrupt, if we configure the hardware pipe. It was my mis-understanding as
each of those hardware blocks can deliver interrupts too. In that way ARM needs

I think this is because gst-openmax needs to be built against
BSP-specific omx headers, and this means we need some of these headers

ntegrating a new sensor which has in-built accelerator, it makes
sense to reduce the silicon area on SoC and use V4L2 instead.

Arnd,
you are correct that omx and v4l2 sit at different levels one being
userside API and other being kernel API.But from the point of view of
integrating these API's in OS frameworks like gstreamer,Android camera
service they are at the same level.I mean one will have to implement
