Adjusting to video orientation in vlc-qt/libvlc

I use libvlc with vlc-qt to load, modify and show various streams and videos. It works well with all videos and streams which have top-left orientation. I have a video created with a smartglass, and it has top-right orientation.
When i opened this video with the vlc media player, it showed correctly, but when i loaded it to my program, it was upside down (because of the orientation).
How can i set it in vlc-qt/libvlc to automatically adjust the frames to the orientation? Based on the vlc media player, it must be possible somehow.
If it is not possible, i would be content with knowing how to get the video orientation from libvlc.

Don't think you can rotate the video from libvlc API, you will need to provide CLI arguments to VLC through your wrapper/libvlc.
See https://wiki.videolan.org/VLC_command-line_help/
Video transformation filter (transform)
Rotate or flip the video
