i have installed vlc 8.6. I'm using fedora core 8 and when i tried to use vlc it is not playing video and gives an error message. can anybody help me to solve this problem


Summary
SELinux is preventing vlc from changing the access protection of memory on
the heap.

Detailed Description
The vlc application attempted to change the access protection of memory on
the heap (e.g., allocated using malloc). This is a potential security
problem. Applications should not be doing this. Applications are sometimes
coded incorrectly and request this permission. The
http://people.redhat.com/drepper/selinux-mem.html web page explains how to
remove this requirement. If vlc does not work and you need it to work, you
can configure SELinux temporarily to allow this access until the application
is fixed. Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi
against this package.

Allowing Access
If you want vlc to continue, you must turn on the allow_execheap boolean.
Note: This boolean will affect all applications on the system.

The following command will allow this access:
setsebool -P allow_execheap=1

Did you install it from the livna repository?

i installed from livna using yum

Hmm, no wonder I gave up on Fedora. Always something wrong with the SELINUX stuff. Anyway, you should execute this:

You will probably need to reboot after that for it to have any effect.

i tried it but i got an error saying setsebool:command not found

Did you run it as root?

yes i tried with root login . i disabled SElinux

i can play audio files using vlc but im not able to play video.i disabled SElinux and then reinstalled vlc ,but still i hav same problem.

Do you still get any warning messages? If not, you may simply need to select a different video codec from the vlc menus (I don't use vlc anymore so I'm afraid you are more or less on your own there - I do remember that you need to look really close to find those settings).

i tried X11,openGL and XVideo extention video output but still not working.
i use vlc to watch video from network. is there any other video player in linux that allows network streaming

You may like xine.

but xine cant play from a network

It should.
