I installed Mplayer in Gentoo. I can play music files just fine through MPlayer, but when I try to play a movie I get this error message:

Error opening/initializing the selected video_out (-vo) device

Also when I try to play anything via VLC it sounds like there is major reverb. I can see the movie file just fine, but the audio is messed up.

Any suggestions on how to fix both would be appreciated.

what settings are you using with mplayer? ie

gmplayer -vo x11 -ao oss -fs -zoom -sws 0

vlc does have an equalizer, maybe you moved it?

Aight, if u want to run mplayer from command line u must type this:

Code:

# mplayer -vo x11 -ao oss -fs -zoom -sws 0 /path/to/file

Where /path/to/file is the location of your video file.

If you want to run mplayer from the gui edit its corresponding shortcut to say this in the command field.

Code:

gmplayer -vo x11 -ao oss -fs -zoom -sws 0

If you are using Gnome like myself and u want to edit the shortcut u will have to go to:

Code:

System > Preferences > Menu Layout > Sound & Video > Mplayer(right click properties, command field)

Optionally u can input whatever resolution u want by changing your shortcut to this:

Code:

gmplayer -vo x11 -ao oss -zoom -x 576 -y 384 -sws 0

Change the X and Y values to your desired resolution.

WARNING: If the resolution is too big the video will lag a lot.

Mplayer Settings:

Code:

Preferences > Audio > OSS > Configure Driver

Device: Driver Default
Mixer: Driver Default
Mixer Chanel: Driver Default

Code:

Preferences > Audio > ALSA > Configure Driver

Device: Default
Mixer: Driver Default
Mixer Chanel: Driver Default

Code:

Codecs & Demuxer > Audio Codec Family > Mpeg Layer-2, Layer-3

Why can't it open up the x11 display?

I had the same problem with MPlayer. Not on linux atm so cant tell you exactly how to fix but you just need to change the video settings. So open MPlayer and go to like options and change the video settings.

**Dr.Gringo** · 04-19-2007, 10:54 PM

Try loading mplayer with the command line method. That should work, or you are definately doing something wrong.

**hexonn** · 04-21-2007, 12:52 PM

what use flags are you using with mplayer? do you have "X" as one

Hosker · 04-21-2007, 05:36 PM

No, I just typed emerge mplayer, how would I go about putting in use flags and what ones should I put in?

**hexonn** · 04-22-2007, 12:37 PM

well, you have a few options then, you cand remove it by using

emerge --unmerge mplayer

and then installing it once again, but this time using -G to get it from the Binhost if you have this line PORTAGE_BINHOST="http://ftp-chi.osuosl.org/pub/gentoo-ps3/grp32/All/" in make.conf

so just use

emerge -vG mplayer

and it will install it very quickly

If you still need to add certain flags just use type

emerge -pv mplayer

and look to see what flags it is using (they're in red i think). For example if aac, flac, dvd aren't selected and you want it to use them, use

echo "media-video/mplayer aac flac dvd" >> /etc/portage/package.use

and finaly use this to update and recompile mplayer with those new flags

emerge --newuse mplayer

You can also do this with VLC and install it using -G
