VOXL UVC Server not connecting

Eric Katzfey

@Kris Okay, that all looks good. What about voxl-uvc-server -d -m?

@Kris Okay, so that shows that voxl-uvc-server is running.

Kris

@Eric-Katzfey
What do I need to do to view the images/video from my UVC camera?

voxl:~$ show-video-device-info.sh
/dev/video2: USB Camera 0bda:3035

Eric Katzfey

@Kris You run voxl-uvc-server to get the frames from the camera. See docs.modalai.com/voxl-uvc-server for more information. Then you run voxl-streamer -c uvc-generic to create an RTSP stream that can be viewed remotely using VLC or QGC. Se docs.modalai.com/voxl-streamer for more information.

Kris

@Eric-Katzfey
This is where I am a little confused. Do I need to SSH into VOXL and run the

voxl:~$ voxl-uvc-server

in one terminal. Then open a new terminal, SSH into VOXL again and run

voxl:~$ voxl-streamer -c uvc-generic

Kris

@Eric-Katzfey Ok, Thank you!!! I finally got it working

Eric Katzfey

@Kris I usually use adb shell to setup two separate sessions. I run voxl-uvc-server in one and voxl-streamer in the other.

Kris

@Eric-Katzfey How can I change the frame rates, etc.
Or edit the config files?

Kris

@Eric-Katzfey I am trying to get better quality because I need to record via some type of Screen Recorder. I would prefer to save the recorded videos to an SD card, but I don't think that is possible.

Eric Katzfey

@Kris Yes, you can edit the config files to change resolution, frame rate, etc.

Eric Katzfey

@Kris We don't currently have a way to save to SD card from the UVC camera. However, you can create your own code to do this. This is a feature that we will be adding in the future.

Kris

@Eric-Katzfey Would I edit the config files from the "uvc-geneirc" at the top or the "uvc-video" at the bottom of the config files?

Eric Katzfey

@Kris If you are using the uvc-generic configuration then that is the one that you would edit.

Kris

@Eric-Katzfey Got it
Thank you for your help and quick responses
