v4l2loopback is loaded! v4l2loopback was unloaded successfully. v4l2loopback was successfully loaded. Please plug in your GoPro and switch it on. If it booted successfully (Charger icon on screen), hit Return

Guessing the GoPro's device name... I can only make an uneducated guess wrt the name of the interface that the GoPro exposes. For me the name of the interface is 'enxf64854ee7472'. This script will try to discover the device that was added last, as you just plugged in the camera, hence the interface added last should be the one we're looking for.

Discovered: enx5ee6e706d905. Using enx5ee6e706d905 to discover the GOPRO_IP. Found 172.22.149.53 To control the GoPro, we need to contact another interface (GOPRO_IP ending with .51).. Adapting internally.. Now using this GOPRO_IP internally: 172.22.149.51 { "status": 2, "error": 0 } { "status": 1, "error": 0 } Sucessfully started the GoPro Webcam mode. (The icon on the Camera should have changed)

You should be ready to use your GoPro on your prefered videostreaming tool. Have Fun!

If you want to use the GoPro in your prefered Video conferencing software (browser and apps works alike) pipe the UDP stream to a video device (that was created already) with this command:

ffmpeg -nostdin -threads 1 -i 'udp://@0.0.0.0:8554?overrun_nonfatal=1&fifo_size=50000000' -f:v mpegts -fflags nobuffer -vf format=yuv420p -f v4l2 /dev/video42

To get a preview of the output in vlc you can run this command To test this try this command(vlc needs to be installed):

vlc -vvv --network-caching=300 --sout-x264-preset=ultrafast --sout-x264-tune=zerolatency --sout-x264-vbv-bufsize 0 --sout-transcode-threads 4 --no-audio udp://@:8554

when i put the vlc command it never loads, and when i put the ffmpeg command it never shows up on google meet.. . i have a gopro hero 8 with firmware updated and i dont know what im doing wrong...

I'm running on Linux Mint 20.3 Una with Kernel linux 5.15.0-41-generic and I have exactly the same problem.

The sudo gopro webcam command does make the GoPro recognise that it's being used as a webcam, but neither VLC nor Cheese nor anything else can actually see a webcam device connected (no device found).

Also using a GoPro Hero8 which I updated using the SD card.

A forum suggested installing guvcview to see if it works. It prompts me to select a device, so I picked GoPro. And then the following displayed on console:

V4L2_CORE: Unable to find parent usb device.GUVCVIEW: version 2.0.6
GUVCVIEW: couldn't open /home/name/.config/guvcview2/video42 for read: No such file or directory

It turns out my problem came from the fact that I had Linux Mint's firewall enabled. Most likely, the computer tried to connect to the GoPro and the connection was refused.

Upon disabling the firewall and trying again, it works perfectly fine.
