when i played vedio file with mplayer ,i can just hear the sound but no vedio
what's wrong? Could anyone kindly help me?

Maybe you just haven't installed the needed codecs, for example divx, mpeg2 or others. I know this problem just because of missing codecs.
But try to find out more by having a look at the log-file, I think mplayer will write on....

show us the **FULL** output from mplayer when run from a console, how did you install the software? what video output are you attempting to use?

i have copied the win32codecs to /usr/lib/win32
i have installed like this:
./configure
make
make install

sorry, coud you plese tell me how to get the full output from the console?

when i try to play DVD,i act like this and no vedio

# mplayer -dvd 1 -alang en -slang hu -dvd-device /dev/hdc

ok, it says you're trying to use fbdev, which (by divine inspriartion) tells me that you don't have the XFree86-devel package installed on your system. if you did then MPlayer would have access to the XWindows based output's which is what you are expecting. install that package, reconfigure, and make and install again. check the output of configure and you should see somethign like currently that will be saying no due to that package not being found.

i think the problem are:

Reading config file /usr/local/etc/mplayer/mplayer.conf: No such file or directory

Reading /root/.mplayer/codecs.conf: can't open '/root/.mplayer/codecs.conf': No
such file or directory

Can't open input config file /root/.mplayer/input.conf : No such file or directory

Can't open input config file /usr/local/etc/mplayer/input.conf : No such file or directory


but how to fix it?

also you don't appear to be running a framebuffer... you're missing on some cool bootup logo's and other pretty things... but that's irrelevant here...

Thank you very much!
i installed the XFree86-devel package(and it require many other package) follow what you said, then it works now!!

could i ask one more question ?

how did you find out the problem from the output message?

it's important to me because i m new to Linux and face to many problem . i want to learn to fix problems .you know linux is good, it aways shows the details

and on top of everything when you run ./configure step on Mplayer, run first
./configure --help
to see what is there for you!!!
Just my $0.02

i just happen to know that that is the last resort when it can't find any other video output to use. you can also see later on that it says "vo [null]" so it's actually given up trying to show the video by that stage.

thank you
i 'll try

you said i missed some pretty things so how can i get them?

when i used ./configure --enable-gui
it said that i didn't install the libpng-devel package
i 'll install it later

Those pretty things are a penguin at boot time, along with other fancies that come with framebuffering. The coolest of which, tux at boot time..



Cool
