Improve video player performance (linux)


I am using a low ressource computer (Atom quad core 1,6 GHz CPU with 1GB of RAM) and i would like to know if there is a way to improve the player performance.

I find ofVideoPlayer a bit heavy.
I am under linux so i can’t use AVFoundation player.

I am doing some quad warping so i imagine it has an impact on performances but i think it could be better.

My app is consuming 170% CPU where playing the same video with MPlayer only uses 30%

thanks a lot
