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.

@Chad-Sweet But yes, you modify the code, build it, and push the IPK to VOXL

@Chad-Sweet
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. -

I’m just not exactly sure what or where I need to modify the voxl-uvc-server to make my UVC camera work.@Kris H264 is not supported in voxl-uvc-server. 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.

I also have another UVC camera, but it only outputs MJPG (compressed) and YUY2 (uncompressed 640x480 30fps) formats.It works for streaming, but I am trying to record the video to the Seeker’s SD card.
Is there a way to do this with Gstreamer or a similar program? -
@Eric-Katzfey
I have tried both fakesink and playbin.
Neither of them work either.
Has anyone gotten gstreamer to successfully work on VOXL1?@Kris We use GStreamer in our voxl-streamer application. It does work on VOXL1.
