Hello, I have a use case, where, I am using subdev configuration to setup video capture. The pipeline is something like this: Subdevs: sd_display, sd_capture Vdev: vcapture (0)sd_display(1) -> (0)sd_capture(1)->(0)vcapture sd_display informs sd_capture of video resolution change and vdev using sd_capture needs to be informed, so, that vdev capture can be stopped. Here, subdev notification/subscription is missing to/from vdev, in my understanding. subdev can send notification to v4l2-dev, but not vdev. Can you help with that? Thanks.
