VOXL UVC Server not connecting
-
I have been trying to connect my UVC camera to view either in VLC or in QGC.
I thought if I followed the guide for the VOXL UVC Server, that it would work or at least get me in the right direction.
When I enter;voxl:~$ voxl-uvc-servernothing happens.

@Kris What do you get if you try

@Kris Okay, that all looks good. What about

@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 -
@Kris You run
voxl-uvc-serverto get the frames from the camera. See docs.modalai.com/voxl-uvc-server for more information. Then you runvoxl-streamer -c uvc-genericto create an RTSP stream that can be viewed remotely using VLC or QGC. Se docs.modalai.com/voxl-streamer for more information. -
@Eric-Katzfey
This is where I am a little confused. Do I need to SSH into VOXL and run thevoxl:~$ voxl-uvc-serverin one terminal. Then open a new terminal, SSH into VOXL again and run
voxl:~$ voxl-streamer -c uvc-generic -
@Eric-Katzfey Ok, Thank you!!! I finally got it working
-
@Kris I usually use
adb shellto setup two separate sessions. I run voxl-uvc-server in one and voxl-streamer in the other. -
@Eric-Katzfey How can I change the frame rates, etc.
Or edit the config files? -
@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.
-
@Kris Yes, you can edit the config files to change resolution, frame rate, etc.
-
@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.
-
@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?
-
@Kris If you are using the uvc-generic configuration then that is the one that you would edit.
-
@Eric-Katzfey Got it
Thank you for your help and quick responses
-
WOW what a great thread, so on time for me Thanks Kris
