Hi,  
I want to use live webcam images in a Processing sketch.  
I have tried the example code from: [https://processing.org/reference/libraries/video/Capture.html](https://processing.org/reference/libraries/video/Capture.html)  
Processing isn’t able to detect my webcam.

I am running Processing 3 on a Raspberry Pi 4 B.  
My webcam is a DSLR.  
I am using a combination of gPhoto2, video4linux2loopback and ffmpeg to create a video stream from the DSLR.  
I am using these libraries to create an mjpeg stream and outputting it to: “/dev/video0”  
I have attached a screenshot of the setup of this stream.

I know this stream is working as I am able to see webcam footage using an online webcam testing service:  
[https://webcamtests.com/](https://webcamtests.com/)  
The “Device Name” I have to select for my webcam is “Dummy video device (0x0000)”.

The problem I have is that “Capture” in Processing 3 won’t detect this webcam.  
I have also tried “Movie” and used my stream location “/dev/video0” as the filename.  
This did not work either.

Does anyone have any ideas on what I can try to get processing to read in my webcam stream?

Thanks  
Harry
