Command line flag for mplayer to use hardware acceleration?

Question

I can make VLC use hardware decoding with

vlc --ffmpeg-hw video.mkv

Is there an equivalent flag for mplayer?

Answer 1

Mind you if you have an nVidia graphics card you should not only specify the -vo device but also give a -vc setting. On my own system I give the following on the commandline:

mplayer -vo vdpau filename

(replacing 'filename' with the actual name of your file of course) and place the following in ~/.mplayer/config:

[vo.vdpau]
vc=ffmpeg12vdpau,ffwmv3vdpau,ffvc1vdpau,ffh264vdpau,ffodivxvdpau,

but there are several different ways of doing this. This method allows you to use different video out devices with MPlayer but will give proper -vc values when you specify -vo vdpau from the commandline.

Hope this helps :).

Answer 2

The command is -vo (video out). For my nVidia network card with hardware acceleration, I use -vo vdpau.

To see all of the video out processors, see mplayer.1.
