Not normal cpu usage when playing video files

Hi guys !

I've noticed that when playing videos (with every player , i've tried them all) there is a noticable cpu usage and with hd videos well the video is extremeley slow and unwatchable .

I have all the gstreamer plugins installed and i'm using gnome environment .

Does anyone know what might be the issue ?

my xorg.conf is :

  Section "ServerLayout"

EndSection

Re: Not normal cpu usage when playing video files

The issue is that Linux and hardware decoding don't necessarily go hand-in-hand like it does on Windows. There are some options though. You can try mplayer with coreavc or one of the mplayer-mt builds. Just search for mplayer in the AUR and you'll see a few options.

Re: Not normal cpu usage when playing video files

Strange , with mplayer-coreavc i have no cpu usage at all . WIth smplayer which is a frotend of mplayer i have the cpu usage problem again .

It seems that i'l have to use mplayer . Is there any way to choose an option for subtitles encoding ? I've tried the -slang option with gr which stands for Greece but it doesn't work .

Also is there an easier way for mplayer to play my files , with default settings , so that i don't have to type a big command each time i want to play a video ?

Thanks a lot for your time !

Yes. You can put all of your personal default settings in the file ~/.mplayer/config. If it doesn't already exist, just create it. On my VDPAU enabled system it looks like this:

[default]

vo=vdpau,xv,
deint=4
hqscaling=9
vc=ffh264vdpau,ffmpeg12vdpau,ffwmv3vdpau,ffvc1vdpau,
channels=2

As far as subtitles go, I never use them so I have no idea.

Re: Not normal cpu usage when playing video files

One tip for subs: ass=yes
ssa/ass subs are really nice.

/me awaits the obligatory unfunny comments about the option name.

When it comes to slang, that depends on that the dude encoding the movie actually put in a language code for the sub stream. Most don't.
