mpeg2 playback slow [solved]

[adamato]

My 2.5GHz machine gets really slow while playing normal mpeg2 or avi video files.

The scenes are not fluid and the cpu is working 99% (using totem, caffeine, xine or mplayer)

My graphic card is nvidia GeForce4 MX 440

my /etc/X11/xorg.conf is appended

 

thanks for your help

With mplayer: what video out are you using? Try mplayer -vo xv <name of mpage2>. Or experiment a bit. Mplayer --vo help gives you a list of all possibilities.

[adamato]

mplayer -vo gave me no usefull info.

To be more precise, mplayer or kaffeine do work with mpeg4 files, but both fail with raw video files (from my videocam) and mpeg2 encoded movies (coded with kino or MS movie maker)

Surprisingly commercial DVD work!

 

codec problems?

No codec problems. No hardware problem. (I play mpeg2 movies (recordings from my tv card) on an ancient P4). No driver problem.....

 

Perhaps the HDD? Open a console login as root and type: hdparm /dev/hdx (where x is the letter of your drive). Make sure dma is on. If it's off turn it on with hdparm -d1 /dev/hdx. With hdparm -Tt /dev/hdx you can see f it made any difference.

[adamato]

Ehi!

For some reason the hardrake puts sometimes DMA off.

The system went back working properly on mpeg2 playback when I pluged a Bluetooth-USB device, and then something changed in the HD config. (???)

 

I decided to disable hardrake at boot.

At the moment it works.

 

thanks for the tip
