Troubleshooting
Typical issues
Video resolution or framerate is lower than expected.
The list of supported image resolutions and framerates depends on the particular webcam model
and can be checked using v4l2-ctl utility (an additional package installation may be required).
To see the full list of supported modes, identify your device (e.g., /dev/video0) and request formats list.
Execute the following commands in the terminal on the Workstation side:
$ v4l2-ctl --list-devices $ v4l2-ctl --device=/dev/video0 --list-formats-ext
If you see the desired mode, but it is not supported for the redirected webcam,
please contact us (
)
and attach the output from both commands.
If there is a bug with the functionality of our software, do the following:
-
Stop the Webcam for Remote Desktop (Linux version) Workstation process and start it again in debug mode:
$ cd ~ $ sudo killall -KILL ftwebcamd $ sudo /opt/ftwebcam/sbin/ftwebcamd -vv > ftwebcam.log 2>&1
- Do not close the terminal while reproducing the issue.
- Enable logging on the Webcam for Remote Desktop (Server) side. For more information, see the Troubleshooting help topic of corresponding product.
If your hardware/OS provides you with just read-only filesystems you need to refer to vendor’s documentation how to enable read/write filesystem.

After you restart the product in logging mode, ftwebcam.log file will be created in the home folder. Add this file to archive.
Send archived logs to us ().
Specify local time when the problem was reproduced and both local and remote user names who was involved in the reproducing.
Disable logging (in order to improve the performance of your PC).
