-> Trying to convince: ;) http://www.linuxtv.org/downloads/video4linux/API/V4L2_API/spec-single/v4l2.html#AEN867 But I also found a section, that older drivers may not support that feature: http://www.linuxtv.org/downloads/video4linux/API/V4L2_API/spec-single/v4l2.html#V4L2-CTRL-TYPE (by the documentation of the V4L2_CTRL_TYPE_CTRL_CLASS value) Now I'm adding code to emulate names for the predefined control-classes. However, it would be nice if the driver supports this...
