The defining aspect of "properties" is to be able to specify to which entity, sub-device, pad, video buffer queue, flash led etc. object the said property is related to. This is mostly orthogonal to what kind of data types the property could have. There's just a single 32-bit reserved field in struct v4l2_ext_control so extending the current extended controls (S/G/TRY) interface is not an option to support properties. A new ABI (but not necessarily even if probably an API as well) would be needed in any case. So for the time being I'd wish we continue to use the name "controls" even if the control type is not one of the traditional ones. -- Kind regards, Sakari Ailus e-mail: sakari.ailus@xxxxxx XMPP: sailus@xxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
