4k logitech Brio, image/jpeg - ksvideosrc0: Internal data stream error

[Matteo Valdina]

Hi,
I used a Logitech brio at 4K and you definitively need a jpegdec element.
In my case I was on Linux so it was a vaapijpegdec you can try with
decodebin.

I remember that it was image/jpeg and not video/jpeg but this depends by
the camera. Often I use the logi c3300 or logi 920 and they use video/jpeg.

Best
Matteo
