Description of problem:
The bug was originally filed as
http://bugzilla.livna.org/show_bug.cgi?id=1243:

When running ffmpeg it crashes with the following error:

ffmpeg: error while loading shared libraries: /usr/lib/libx264.so.54: cannot
restore segment prot after reloc: Permission denied

This crash occurs as both a normal user and root.

----

The problem was later identified as a problem with text relocations. As per 
http://post-office.corp.redhat.com/mailman/private/memo-list/2006-November/msg00262.html
I am filing this bug here as well.

Version-Release number of selected component (if applicable):
selinux-policy-targeted-2.4.2-3.fc6

How reproducible:
100% with SELinux in enforcing mode

Steps to Reproduce:
1.start ffplay (or anyother application using ffmpeg libraries, e.g., it is
reproducible with mplayer as well) and it crashes with error message:

ffplay: error while loading shared libraries: /usr/lib/libx264.so.54: cannot
restore segment prot after reloc: Permission denied

(the same selinux error is generated by rhythmbox and mplayer or probably any
other application using ffmpeg libraries or gstreamer-ffmpeg).
2. when applying chcon -t textrel_shlib_t /usr/lib/libx264.so.54 everything works
3.
  
Actual results:
programs using libx264 doesn't work without applying chcon on /usr/lib/libx264.so.54

Expected results:
programs should work ouf of the box
