Video Playback via HDMI (Debian Jessie 8.2) on BBB

I am trying to solve a problem with my video output via HDMI, a situation is as follow.

I have device (BeagleBone Black) which runs on Debian Jessie 8.2, I developed an application in Qt5 which embeds MPlayer in QMainWindow. When I launch that application it doesn’t show video playback inside that application’s window (It works well on my Ubuntu VM). I figured out that I have error which repeats all the time in my /var/log/Xorg.0.log → “FBDEV(0): FBIOPUTCMAP: Invalid argument”. I am not sure where is the problem, as video reproduction also works when I run it via vnc client, something with hdmi? video drivers? or Qt? I am really stucked, so please help! Thanks
