VOXL camera configuration
-
@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.@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.

@Eric-Katzfey
If possible, could you please provide me with a VOXL1 working pipeline (streaming or recording) using any UVC camera of your choice?@Kris That's not how it works on VOXL1. The voxl-uvc-server application places frames into an MPA pipe and the voxl-streamer application (based on gstreamer) reads those frames and processes them for output using RTSP. However, I do believe that I did try command line gst-launch-1.0 style pipelines with UVC cameras in the past and they worked. I don't have an example of one though. You may want to start with one of our supported UVC cameras first and then try to get your particular UVC camera working. I always start with the Logitech C270. We list the specific cameras that we support because each one caused us some issues and required code changes to make it work. We even had to fork the libuvc library in order to make changes to that to get some of the cameras working properly.

I bought the Logitech C270 and tried testing it with some Gstreamer commands.
So far I have been able to use it on my Linux PC with these commands.Connected to PC and viewing video;
gst-launch-1.0 -v v4l2src ! video/x-raw,format=YUY2 ! videoconvert ! autovideosinkConnected to PC and recording to PC;
gst-launch-1.0 v4l2src device=/dev/video0 ! image/jpeg,width=640,height=480,framerate=30/1 ! jpegdec ! x264enc ! qtmux ! filesink location=C270.mp4 -eHowever, when I connect the C270 to the Seeker I cannot get any of these to work.
I have tried different video devices 0-3 and I have also substituted theautovideosinkwithfakesinkbut these changes are still not working.Could you please show me a Gstreamer example for this Logitech C270 camera that works on the Seeker?
I would like to either stream, record, or stream+record (possibly using tee) the video using gst-launch-1.0.
Thank you
