I have given below the configuration of a low end system Motherboard - Intel 945GSE Processor - Intel Atom CPU N270 1.60GHz Ram - 1 GB Graphics - Intel GMA950 Mplayer plays very slowly sometimes frame by frame or the video fails to load at all for 1080/720p h264/mpeg encoded videos in mkv/mp4 containers. How to enable video/hardware acceleration for smooth playouts. I have read about VDPAU for nvidia based graplics cards and also VA-API for Intel based chipsets. Please let me know of details. Regards, Vijay.
