RE: Stereo Camera Calibration update?posted in Ask your questions right here!
Thank you Alex, I was finally able to calibrate the stereo cameras and the tracking camera.
You were spot on with the issue. It was because of the angle and focus on the stereo cameras and the angle on the tracking camera.

Manual Flight Mode to match Position Flight Modeposted in Seeker
Hello,
I am just looking for the best way to calibrate the Seeker (Manual Flight Mode) motor's RPM's to match the Position flight mode RPM's.
I would like to be able to switch from Position flight mode to Manual flight mode without the Seeker suddenly rocketing to the ceiling or suddenly crashing to the ground (Manual to Position).
Any help would be much appreciated.
Thanks -

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

RE: uvc_get_stream_ctrl_format_size failedposted in Ask your questions right here!
@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? -
RE: uvc_get_stream_ctrl_format_size failedposted in Ask your questions right here!
@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. -
RE: uvc_get_stream_ctrl_format_size failedposted in Ask your questions right here!
@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? -

@tom
Sorry to bother you again, but I am not seeing the h264 format supported in the main.c script you provided for the voxl-uvc-server. Is it possible to edit the voxl-uvc-server main.c script to accept h264 format at 1920x1080 @30fps? -
RE: uvc_get_stream_ctrl_format_size failedposted in Ask your questions right here!
@tom
Do I paste this in the voxl terminal?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=8554Does this have uvc frame or video capture capabilities?

@Steve-Turner
Thank you for your help.
I realize you are not part of the ModalAi Dev Team, but I would like to ask for your help with this.
There is more information that I have posted on this thread.
I am lost, and would really appreciate any kind of help you could provide.Thank you.

RE: uvc_get_stream_ctrl_format_size failedposted in Ask your questions right here!
@tom
Thank you, I will give this a try.
I am trying to use H.264 on this camera.
This is the second UVC camera that I’ve purchased because I am trying to log the frames from voxl-logger. From what I understand, H.264 output is the format that can do this.
Is there a way to call for only the /dev/video2 to start with the voxl-uvc-server or gstreamer?
Does the voxl-uvc-server accept h264 1920x1080 @30fps? -
RE: uvc_get_stream_ctrl_format_size failedposted in Ask your questions right here!
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?
