Video-tracker on linux : videotrackerCombinedCalibrationFile12.json not found and VIDIOC_QUERYMENU: Invalid argument

[Olm-e]

hello, I'm trying to use the HMD (1.2) on linux machine (mint 17 and debian8) with OSVR-Core master branch, compiling well.

I'm using the osvr_server_config.HDK12ExtendedLandscape.sample.json sample renamed as default, the camera is lightning on, and accessible by guvcview (with root)

I can access and use IMU orientation correctly in python/blender :D, but not the position that stays at zero.

when launching the server I receive these errors in the prompt :

`sudo ./osvr_server [sudo] password for user: [OSVR Server] Using default config file - pass a filename on the command line to use a different one.

I indeed cannot find the calibration .json file,

is the problem related to https://github.com/OSVR/OSVR-Core/issues/339 and simple basic lack of video support for uvc cam ?

thanks

A camera firmware upgrade is recommended to access the camera from OSX/Linux configurations. You can find the upgrade tool here: http://osvr.github.io/using/

This may not be the only problem, but please start with the upgrade.

Yes, start with the upgrade. It probably still won't work (well) after that because OpenCV doesn't let us specify a particular camera to use, etc, but it will be a lot closer to working. Not finding the calibration file is not a fatal error: autocalibration proceeds during usage. See https://github.com/OSVR/OSVR-Docs/blob/master/Getting-Started/HDK/Video-Based-Tracking-Calibration.md

[uberscientist]

Is this the camera upgrade tool you're talking about? http://resource.osvr.com/public_download/Drivers/OSVR_IR_Camera_Firmware_update-5SF006N2_v0007.rar

It's a windows binary and OP and I are on linux, or was there a link I missed?

[rpavlik]

Yes, that's the one. Unfortunately there isn't a Linux version available of that firmware update, so you'll have to find/borrow a Windows PC to do the upgrade.

[Olm-e]

ok... I also had to find a Windows machine, as it doesn't work on Wine neither ... :/ So the cam is recognised now, and try to callibrate. I had it (badly) working once, but now it stay stuck after the "that distance looks good, hold it right there." sentence in the prompt. will try to upgrade OSVR-Core with latest changes ... EDIT: no change with fresh update from git, stuck in calibration when "distance looks good" ... I'm wondering if I need to "upgrade the HDK firware" too, will need another pass by a windows machine it seems... Also, I can't find the videoTrackeralibrationUtility binary. Is it available for linux ? thanks.

I just want to update and let you know that updating the firmware does indeed work on linux (I have verified this). See: https://github.com/OSVR/OSVR-Docs/blob/master/Utilities/UpdateHDKLinux.md

[rpavlik]

@conzar the IR camera has its own firmware described above, and that update does not run on Linux.
