Hi, I got completely confused while trying to create private controls with control API and when I finally got down to sanity checks in v4l2_ctrl_new() in v4l2-ctrls.c... It would be nice if the following explanation by Hans (archive msg69922) or maybe some more elaborate version could somehow make its way to Documentation/video4linux/v4l2-controls.txt :-) Regards, Krzysztof -- 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
