uvc_get_stream_ctrl_format_size failed

@tom
Ok, thank you for the explanation.
I will read up on gstreamer and try to figure this out.
You mentioned that I would run this on VOXL2.
I dont have a VOXL2. Does this work on VOXL for the Seeker? -
@Kris Apologies, I'm not sure if that will work on VOXL1. Do you have a hires mipi sensor on your VOXL? It would allow you to avoid a lot of trouble
-
@tom
No, I dont have a hires mipi sensor on my VOXL. I am using the TOF, Stereo, and Tracking sensors specifically for indoor flights.
I am just trying to record frames or video from a connected uvc camera while in flight.
I am also trying to set one of my stereo cameras as the QVIO instead of the tracking camera. Again this is just for indoor flights. I have also asked about this QVIO setup in this thread, but have not received a response other than pointing to the extrinsics ModalAi page. -
@tom
The command you sent me earlier this week did not work on the VOXL platform. I tried variations on both our e-CAM83 and Aruducam IMX335 uvc camera modules.Could you please point me to a uvc camera that will work with the
voxl-uvc-server?
Our main goal is to connect a uvc camera to the Seeker and be able to capture frames or video (streaming is not necessary) and send them to an onboard SD card (possibly usingvoxl-logger.Would this Blue Robotics uvc module work? Meaning, is it capable of connecting to the
voxl-uvc-serverand be able to send frames and/or video to the onboard SD card usingvoxl-loggeron the VOXL1 Seeker Dev Drone? -
@tom
I have also noticed that when I updated my platform to 0.9 the streamer.conf has changed.
Now our Arducam IMX335 is not even working (it had no problems streaming before).0.9 streamer.conf

@tom
Do you happen to know some Gstreamer commands for the Logitech C270 uvc camera?
I am trying to get either a streaming or recording command to work on the Seeker, with no luck so far. -
@Kris I don't have that specific webcam or a VOXL1 but with a different one and a VOXL2, all I have to do is run
voxl-uvc-server, see output below:voxl2:/$ voxl-uvc-server loading config file Creating new config file: /etc/modalai/voxl-uvc-server.conf ================================================================= width: 640 height: 480 fps: 30 pipe_name: uvc =================================================================I'm able to pull up the stream using voxl-portal (going to IP of my VOXL2 in browser)
Then alternatively I'm able to use this gstreamer command:
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=192.168.1.124 port=8554to pull up the video stream in QGC

@tom
Thank you for your examples.I was asking about the C270 camera because @Eric-Katzfey had mentioned that he starts his camera testings with this model in order to locate where issues are coming from on other camera models.
I do appreciate your support.
I will continue to try different Gstreamer commands. -
@Kris I understand, your solution will likely be similar to what I posted above

@tom
I was able to stream the video from voxl-portal,voxl:~$ voxl-uvc-server -d Enabling debug messages voxl-uvc-server starting Image resolution 640x480, 30 fps chosen UVC initialized Device found Device opened uvc_get_stream_ctrl_format_size succeeded for format YUYV Streaming starting Got frame callback! frame_format = 3, width = 640, height = 480, length = 614400, ptr = (nil) * got image 30 * got image 60 * got image 90 * got image 120 * got image 150but I cannot get the Gstreamer to work for QGC.

I had to change x264 to omxh264, and had to completely remove
speed-preset=ultrafast tune=zerolatencyfrom the command because it wasnt playing well with VOXL1. -
@Kris Well now that you have
voxl-uvc-serverworking you should be able to use voxl-streamer on top of that to get a stream going -
@tom
Yes, I am able to get the stream working with thevoxl-streamer -i uvccommand,
but I am trying to get a Gstreamer command working so that I can build a pipeline to record the frames.voxl:~$ voxl-streamer -i uvc ERROR: object missing input-pipe WARNING: Failed to get default pipe name from configuration file ERROR: object missing bitrate WARNING: Failed to get default bitrate from configuration file Camera server Connected Stream available at rtsp://127.0.0.1:8900/liveGstreamer;

@Kris The intention with the Logitech camera was to use it with voxl-uvc-streamer as Tom pointed out. That way you have a complete working setup and then you can start changing one thing at a time to get to what you want. If you want to switch to a different camera then you can see the differences in the new camera from the Logitech camera and try to debug that way. If you want to add a record feature with GStreamer then you can fork our voxl-streamer code and add the functionality into that. If you want to do it with a gst-launch-1.0 command line pipeline then you are farther away from anything we currently support and it's going to be hard for us to offer much help. I do think that what you are trying to do should be possible.
