trummerschlunk commented 3 years ago

Hello, thanks for the software. I am having issues getting it to work. It always ends with and error while starting webcam mode. Here is the output. Any hints very much appreciated. Thanks.

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.

Your GoPro get a wrong ip. If i switch my GoPro Connection to MTP i get a simliar IP. Did you changed the Connection type to "GoPro Connect"?

Hello,

I appear to be having the same issue.

Is there some configuration that needs to be done that I have missed? @DogyDHW what do you mean by "GoPro Connect"?

chrisfoster121 commented 2 years ago

I just noticed that this only supports the Hero 8+ (if I read that correctly). That is likely my issue.

DogyDHW commented 2 years ago

@chrisfoster121 some older GoPro's are support a webcam mode on the official Windows App with the newest firmware. Look in the settings on your GoPro for USB-Connection. I need to change it from "MTP" to "GoPro Connect" in this setting. Its maybe working on your GoPro :)

msonowal commented 2 years ago

Same issue on hero 10, and I do not see any settings related to USB connection. Anybody success with hero 10?

oVerde commented 2 years ago

What is GoPro Connect @DogyDHW ?

My GoPro is the Hero3, does any one of you @jschmid1, @juchem, @raleighlittles guys know anything?

raleighlittles commented 2 years ago

Sorry @oVerde , I don't know anything about this. I'm not involved in this project at all; you might've seen my name on a recent commit but that was a documentation change only. I don't have this issue with my GoPro Hero 10.

Did you see this response from @DogyDHW ? https://github.com/jschmid1/gopro_as_webcam_on_linux/issues/30#issuecomment-989190899

Using Arch Linux, I have the same problem with a Hero 9. USB mode is set to GoPro Connect.

This issue hasn't been resolved yet? While the script can be a work-around, doing that manual work isn't really a solution.

Here's my log

I was getting the same. What worked for me was to run the command with -d flag :

sudo gopro webcam -d enxcacfe3b065ad

To find out the device number run:

ip a|grep enx

This only works if the GoPro is connected via USB and turned on.
