I am developing a system to play 2 full HD videos on 2 monitors through Adobe Air on Mini-ITX system. However, the video playback a lone use a lot of CPU resources causing playback become extremely lag and unsmooth. I have try to play mp4, f4v video format. Both are extreme high CPU usage. The only playback that is smooth is mpg (mpeg2) file format. However, it does not supported in Adobe Air.
How should I do now? What is the best alternative full HD video format that will use very little resources? Thanks.
