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?
