how "extra-controls" of v4l2src property works
- I have to pass exposure time using gstreamer pipeline.
- After some online reading i found that we can send it using "extra-controls" property of v4l2src.
- How this property mapped with V4L2_CID_PRIVATE_BASE or how to map this property with any v4l2 camera driver.
- If i want configurable property in camera driver using gstreamer pipeline then how to achieve that?
