Hallo, Firs of all, your raw stream is working because it use smaller frame size. Raw stream is 160x120, jpeg is 640x480. I'm sure if you will test same size for jpeg it will work too. Second, your cam provide correct data for raw stream (bitrate, urb size). But also provide same settings for jpeg. It mean even if jpeg consume lesser than raw, we do what webcam request us.
The quirk=128 make recalculation only for raw stream. We still need quirk for jpeg stream.
