[Sony RX100 VII] Camera does not seem to return a JPEG image in LiveView mode

Hello!

I'm a newbie trying to turn his Sony RX100 VII into a webcam. I've been following this very clear tutorial (https://medium.com/nerdery/dslr-webcam-setup-for-linux-9b6d1b79ae22), although I'm getting stuck at a certain point:
When I execute gphoto2 --stdout --capture-movie | ffmpeg -hwaccel nvdec -c:v mjpeg_cuvid -i - -vcodec rawvideo -pix_fmt yuv420p -threads 0 -f v4l2 /dev/video0
I get the following message:
*** Error ***
Sorry, your Sony camera does not seem to return a JPEG image in LiveView mode
ERROR: Movie capture error... Exiting.
Movie capture finished (0 frames)
pipe:: Invalid data found when processing input

Unfortunately, I'm really not an advanced linux/gphoto user, so I don't know how to troubleshoot this.
All I can say is that I just found this gtihub issue (https://github.com/gphoto/libgphoto2/issues/180) with a similar message, but I'm not sure it actually is the same issue as me.
I'm using LinuxMint 20, using gphoto2 2.5.23 and libgphoto2 2.5.25.

Thansk a lot :)
