Hi Guennadi and all,
I've been trying to make my omap4 camera host driver to allow YUYV ->
NV12 color conversion, and add that to the supported host-client
formats, but I think I have hit the wall with the host design.
I noticed that the soc_camera seems to be designed to just pass-through
the client supported formats (i.e. if my sensor supports YUYV and JPEG,
those will be the supported formats only)
Now, in my host driver, I have a feature to do a color conversion to
NV12, but I'm still not sure on how to expand the supported formats to,
say: YUYV, JPEG, and NV12 (which would be available only if the client
outputs YUYV, of course).
I was trying adding a customized get_formats function, but as
soc_camera_init_user_formats anyways depends heavly on the sensor's
enum_mbus_fmt, it's hard to add supported formats that the sensor
doesn't directly support.
Has this been done before? Any advice?
Regards,
Sergio
