I'm using external usb camera plugged to my raspberry 3b+. Since I'm not using raspicam, but the uvc driver I can't just set the framerate in config file like when you are using raspicam.



Is there a way to set it somwhere?

          v4l2-ctl --set-parm=30



          seems like it should change the fps, you also need to specify the device with



          --device=



          With



          set-fmt-video=width=1024, height=640



          you can change the resolution. The changes however seem to not affect the video though. Fps seem to have no effect at all, so the mjpeg stream stutters alot, and WebRTC works great even though it's set to 5 for example. Changing the resolution only seems to upscale the image with 0 quality improvement.

                    What visual should I use to simply compare current year value vs last year in Power BI desktop

                    Image
                    0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?
