VOXL camera configuration

Please do not try to modify the Seeker, it is unlikely you will be successful.
Have you tried to log your UVC camera on a linux computer? can you use that same method on VOXL?

@Chad-Sweet
I apologize if I gave the impression that I am trying to modify the Seeker.
I am just wondering if it is possible to use Hires + TOF + Stereo, with one of the stereo cameras acting as a tracking camera. If it is possible I would gladly purchase one of ModalAi's Hires cameras. At the moment, I am using TOF + Tracking + Stereo and attempting to stream and record a UVC camera.Yes, I have tried viewing my UVC camera on my linux PC with several programs like OBS, guvcview, and Gstreamer.
I am able to log my UVC video using gstreamer on my linux PC as well.
However, when I try to connect my UVC camera on VOXL1 for the voxl-uvc-server, I receive this error;voxl:~$ voxl-uvc-server -d Enabling debug messages voxl-uvc-server starting UVC initialized Device found uvc_open failed UVC exited voxl-uvc-server endingI have also tried using Gstreamer on the VOXL but I am not able to get a connection.
Here is the pipeline I used to stream the UVC camera on VOXL;gst-launch-1.0 -v v4l2src device=/dev/video2 ! video/x-raw,format=YUY2 ! videoconvert ! omxh264enc speed-preset=ultrafast tune=zerolatency ! rtph264pay name=pay0 ! udpsink host=192.168.110.152 port=8554I am not able to get a successful connection to the UVC camera on the VOXL. The led on the camera lets me know when there is a successful connection, and only the power led was on.
I have tried a simple capture and send video command but this did not work either. I have tried all my dev/video options (video0~video3) but none of them work.gst-launch-1.0 v4l2src device=/dev/video0 ! decodebin ! omxh264enc ! rtph264pay ! udpsink port=8554Is there a way to install v4l2-utils on the VOXL1?
Since the VOXL is not able to communicate/recognize the attached UVC h264 camera, than I think that VOXL might be missing the v4l2-utils package that my UVC camera needs.
Does the voxl-utils ipk contain the v4l2 parameters? -
To change the image sensor on Seeker, you would have to disassemble the front end which would likely result in damage. It is really not recommended.
gstreamer should work similar to your USB setup on your Linux PC. Do you have a gstreamer command that is working on your PC?
if you type
ls -la /dev/video*with your camera plugged in and unplugged, you should easily see which device it is enumerating toWhat is the exact module number of the camera you are trying to install?

The gstreamer commands work on my Linux PC.
I am able to stream and record video when my UVC 2.0 camera is plugged directly into my Linux PC.
I just have to change some of the pipeline, because x264enc is not recognized on the VOXL. I use x264enc on my PC and omxh264enc on the VOXL.
I am using the e-CAM83 UVC 2.0 camera.
There is detailed information about this camera in this post. -

@Chad-Sweet
If it’s possible to configure the Seeker with Hires + TOF + Stereo, where one stereo camera is acting as a tracking camera, can I send my Seeker back to ModalAi for this setup?
Would the Seeker still have the VIO and VOA capabilities with this kind of setup? -

voxl-uvc-server only supports a few data types. You may need to modify the code to support the format of the e-CAM83
If you have a gstreamer command that works on your linux box, it should work on VOXL as well though.

Just to confirm,
If I modify the voxl-uvc-server/src/main.c file, to allow H264 format, would this work?
Or does the modification need to happen somewhere else in the main.c?
I’m just not exactly sure what or where I need to modify the voxl-uvc-server to make my UVC camera work. -

See https://gitlab.com/voxl-public/voxl-sdk/services/voxl-uvc-server/-/blob/dev/src/main.c#L64. You may be able to add support for it but there are some tricky aspects to H264 streaming that you would need to be aware of before attempting it. Seems like you should start with the video3 interface since it supports 640x480 YUYV

It seems as if VOXL1 is not able to connect with my UVC camera.
