Below are the errors that I am getting.

Please let me know what you think.
Thank you
I had also tried “decimator”: 1,
for the UVC generic in the streamer.conf file, and that did not work either.{ "conf-version":"1.3", "configuration": "hires", "uvc-generic": { "input": { "interface": "mpa", "mpa-camera": "uvc" }, "output": { "stream": { "rotation": 0, "width": 640, "height": 480, "decimator": 1, "bitrate": 1000000 } } -

@Kris You're on a pretty old platform release, I would start by updating to 0.9: https://developer.modalai.com/asset/view/115

I've updated my platform to 0.9 and I am still unable to successfully open the uvc camera.voxl:~$ lsusb Bus 001 Device 008: ID 2560:c184 Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 002: ID 0424:2514 Standard Microsystems Corp.

@Kris Yeah that's just the default that
voxl-uvc-serveruses if not explicitly specified otherwise with the-rflag.You can use
show-video-device-info.shand that may provide some clues.What is the part number or make and model of the UVC camera you're using? It's possible it's supported image formats don't match up with those supported by

I have a feeling that maybe the problem is deriving from my camera’s GUID Format.
Does the voxl-uvc-server acceptGUID: 4832363400001000800000aa00389b71
for h264 format?
How would I go about correcting the guidFormat to match up with the voxl-uvc-server? -
@Kris You can see supported format info here: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-uvc-server/-/blob/master/src/main.c#L64
Another thing to try out is using gstreamer instead of voxl-uvc-server + voxl-streamer with a pipeline similar to the following:
gst-launch-1.0 v4l2src device=/dev/video2 ! video/x-raw,format=YUY2 ! videoconvert ! x264enc speed-preset=ultrafast tune=zerolatency ! rtph264pay name=pay0 ! udpsink host=192.168.1.97 port=8554The pipeline may need to be tweaked slightly but it's one I've used before for other UVC cameras that voxl-uvc-server was unhappy with

@tom
Thank you, I will give this a try.
I am trying to use H.264 on this camera.
This is the second UVC camera that I’ve purchased because I am trying to log the frames from voxl-logger. From what I understand, H.264 output is the format that can do this.
Is there a way to call for only the /dev/video2 to start with the voxl-uvc-server or gstreamer?
Does the voxl-uvc-server accept h264 1920x1080 @30fps?
