Hi Laurent and Sakari, Current media entity contains a few fields to identify a dev node (name, type, group_id). The entity name is the v4l2 dev node name such as "/dev/video0" "/dev/video1". There is no information who is "/dev/video0" and who is /dev/video1". This makes that, after query the media_entity the application still could not figure out who is /dev/video1". However in V4L2 devices, there is a driver name that the vendor can assign a specific name such "WIFI CAPTURE" or BACK_CAMERA" to the driver name. Is it possible to add the driver name into the media_entity? This makes that, if the userspace application knows the driver name it can use the driver name to find the dev node.
