Hi, regarding v4l_subdevs: I want to get informed if a stream has actually started running because I need to toggle a gpio-trigger to quirk a mipi-transcoder-chip. I do know v4l2_subdev_video_ops s_stream but this is not what I need because it's before the actual start. Any ideas?
I guess I could hack it with a worker-thread, but is there a better solution?
