Linux and VLC error message Help.?
I currently have Fedora 10 and I installed VLC media player. When ever I open it to play a song it gives me 2 errors and the song sounds real choppy. These are the errors I get… How do I fix them?
Summary:
SELinux is preventing vlc from loading /usr/lib/sse2/libswscale.so.0.6.1 which
requires text relocation.
Detailed Description:
The vlc application attempted to load /usr/lib/sse2/libswscale.so.0.6.1 which
requires text relocation. This is a potential security problem. Most libraries
do not need this permission. Libraries are sometimes coded incorrectly and
request this permission. The SELinux Memory Protection Tests
(http://people.redhat.com/drepper/selinux-mem.html) web page explains how to
remove this requirement. You can configure SELinux temporarily to allow
/usr/lib/sse2/libswscale.so.0.6.1 to use relocation as a workaround, until the
library is fixed. Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.
Allowing Access:
If you trust /usr/lib/sse2/libswscale.so.0.6.1 to run correctly, you can change
the file context to textrel_shlib_t. "chcon -t textrel_shlib_t
‘/usr/lib/sse2/libswscale.so.0.6.1’" You must also change the default file
context files on the system in order to preserve them even on a full relabel.
"semanage fcontext -a -t textrel_shlib_t ‘/usr/lib/sse2/libswscale.so.0.6.1’"
Fix Command:
chcon -t textrel_shlib_t ‘/usr/lib/sse2/libswscale.so.0.6.1’

SElinux is a very high security version of linux and is very limited in what it allows a
the computer to do. It is used mostly for servers and high risk situations. It will be a pain in the neck for use for a desktop/home computer.
I see in your post that you have a link to remove the requirement and allow VLC to function.
See the links below.
THis will probably just turn it off not remove it. Just use ‘System -> Administration -> Security Level and Firewall’ select the ‘SELinux’ and select disabled and reboot, now SELinux is turned off.
If you do a google search "how to remove SElinux" you will find some people who say the best solution is to reinstall. That is a call you will have to make. You could reinstall fedora or another distro.
