Subject: I just wondering how to set shutter or aperture value in uvc driver.

Hi Laurent,

I try to add the more exposure methods of the M-5MOLS driver. Currently,
the only 2 exposure type are available in the M-5MOLS driver -
V4L2_EXPOSURE_AUTO, V4L2_EXPOSURE_MANUAL. But, the HW is capable to  

So, I found the only UVC driver looks like using extra enumerations
V4L2_EXPOSURE_SHUTTER_PRIORITY, V4L2_EXPOSURE_APERTURE_PRIORITY.
But, I don't know how to set the each value in the each mode.

The way pointed the specific value is only one - V4L2_CID_EXPOSURE_ABSOLUTE.
So, how can I set the specific value at the each mode?


Regards,
Heungjun Kim
