Hello @kvamvake,
Which camera are you using?
Do you connect your camera using USB or the Camera Serial Interface (CSI)?
Also, what do you see when you run edge-impulse-linux --verbose?
Regards,
Louis
Minute 1, goal 1… I have the same fault too, I’m using Logitech c270 usb web cam and my verbose output…

Raspi 4B,
Ubuntu 21.10 (GNU/Linux 5.13.0-1015-raspi aarch64)
Hey all,
I’ve got the same issue on Raspberry Pi 4 with Logitech Webcam C925e.
Until now I simply deployed my model using: edge-impulse-linux, and everything worked fine. But now I’m trying to run example-linux-with-twilio from GitHub. And I always get the error: Capture process failed with code 1. Anyone can help me? 
Here is what I got by running edge-impulse-linux --verbose:

Hello @FIRAS,
Maybe this thread can help you: Using raspberry pi camera - #2 by louis
Let me know if it fixes your issue.
Best,
Louis
Actually I have the same problem too
Error: “failed to run impulse capture process failed with code 1”
How to solve this problem would anyone like to share ??
Hello i am having the same problem. my error message is:
[SER] Using microphone hw:1,0
[GST] checking for /etc/os-release
Failed to initialize linux tool Capture process failed with code 1
I am using camera Arducam 12MP IMX708, Raspberry Pi 5 with Bookworm.
the camera works perfectly fine in the command line with rpicam
For RPI5, make sure you install: sudo apt install -y gstreamer1.0-libcamera
Then look for your device with : gst-device-monitor-1.0

I was having the same problem starting Edge Impulse on Arduino Uno Q until I plugged in two cameras to my USB-C hub, then I was prompted on which camera to use and it started up properly.

Hey @CapperLabs first of all welcome to the Edge Impulse community!
how did you run Edge Impulse? Did you use the command
edge-impulse-linux --gst-launch-args "libcamerasrc camera-name="/base/axi/pcie\@1000120000/rp1/usb\@200000-2:1.0-03f0:654a" ! video/x-raw,width=640,height=480,format=YUY2 ! videoconvert ! jpegenc"
or similar?
That didn’t work for me. When I ran
gst-device-monitor-1.0 The name of the device was “Streaming Camera: Streaming Cam”
and if I tried to use that name in the edge-impulse-linux command it didn’t like the colon and the spaces in the name and gave me an error “could not find device Streaming”
However, when I plugged in two cameras, then when I ran edge-impulse-linux with no args, it gave me a choice of the two cameras \dev\video0 and \dev\video3, and then connected to edge impulse correctly.

Thanks for sharing @CapperLabs
Could you please share more details about your cameras? Did you try with 1 or the other? What do you get when you try gst-device-monitor-1.0 with each one separated? and together?
Please do share all the logs here!
I will do some experiments with different configurations and capture the screens for you this week. I’m using the Arduino Uno Q and a ABIWAZY 9-n-1 USB-C hub. I have a few different cameras I can try. I have never used Edge Impulse before this project, so I’m still learning.
