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 } } -
The
Frame size mismatch 614400 12441600is always the same. -
@Kris You're on a pretty old platform release, I would start by updating to 0.9: https://developer.modalai.com/asset/view/115
-
@tom
Ok, thank you. I will try that first. -
@tom
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 Are you sure that your UVC camera is 640x480 resolution?
-
@tom
Yes, in the debug messages, it says that it is 640x480.
Is there another way to check the resolution? -
@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
voxl-uvc-server -
@tom Ok, Thank you I will try that now.
Here are some details of my UVC 2.0 camera.

@tom
This is all the information I get fromshow-video-device-info.shvoxl:~$ show-video-device-info.sh /dev/video2: e-CAM83_USB 2560:c184 /dev/video3: e-CAM83_USB 2560:c184 -
Is there any chance I can get 1920 x 1080 @30 fps using h264 in the voxl-uvc-server?
Or is 640 x 480 the only option in the voxl-uvc-server? -
The rest of the information about my current uvc camera is here.

I gave this a try, but no luck.voxl:~$ voxl-uvc-server -d -r 1920x1080 -f 30 Enabling debug messages voxl-uvc-server starting Image resolution 1920x1080, 30 fps chosen UVC initialized Device found uvc_open failed UVC exited voxl-uvc-server ending -

@tom
May I ask what image formats thevoxl-uvc-serversupports? -
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
