Checking if vdpay is working on Linux using SMPlayer

cdysthe · 08-09-10, 08:51 PM

Hi,

I am running SMPlayer Version: 0.6.9 (SVN r3447) Using MPlayer SVN r31722 on Linux Mint 9 x64. My laptop has a nvidia 9300GM graphics card and I have the latest driver from nvidia installed. I have SMPlayer set to use vdpau. How do I know that vdpay is actually woring? I do not know if it helps, but this is part of a typical log when playing video:

means you are not using VDPAU

Use the command line.
Open the folder where your movie is and launch mplayer:

Code:

mplayer -ao pulse -vo vdpau -vc ffodivxvdpau,ffh264vdpau,ffmpeg12vdpau,ffwmv3vdpau,ffvc1vdpau MOVIENAME

Of course MOVIENAME is the files name. The many vdpau items are there to make sure all encodings are played (h264, divx, wmv, vc1, mpeg1/2).

Basically the idea is the following:

mplayer -vo vdpau -vc *vdpau moviename

You have to explicitly set the vdpau output device to *vdpau with -vo AND -vc to ensure hardware decoding, setting only -vo vdpau will use software decoding to the vdpau output device.

PS. If it works, you should have ~10 % or less CPU usage on 1080p movies...

Thanks! I did a test using mplayer and the string you gave and got:

MPlayer SVN-r31722 (C) 2000-2010 MPlayer Team
mplayer: could not connect to socket

So it doesn't work. I would assume I either need to build my own mplayer or find a ppa with vdpau enabled mplayer builds. I will look into that.

Thank you guys. Based on your input I found out what was wrong (needed to compile mplayer) and got it all working.
