Summary:

SELinux is preventing /usr/sbin/httpd from using potentially mislabeled files
video0.  Happens when trying to view a video stream from the zoneminder web UI.

Detailed Description:

SELinux has denied the httpd access to potentially mislabeled files video0. This
means that SELinux will not allow httpd to use these files. If httpd should be
allowed this access to these files you should change the file context to one of
the following types, squirrelmail_spool_t, httpd_cache_t, httpd_tmpfs_t,
httpd_tmp_t, httpd_squirrelmail_t, httpd_cvs_rw_content_t,
httpd_git_rw_content_t, httpd_sys_rw_content_t, httpd_nagios_rw_content_t,
httpd_nutups_cgi_rw_content_t, httpd_squid_rw_content_t,
httpd_smokeping_cgi_rw_content_t, httpd_apcupsd_cgi_rw_content_t,
httpd_prewikka_rw_content_t, httpd_awstats_rw_content_t,
httpd_w3c_validator_rw_content_t, httpd_user_rw_content_t,
httpd_cobbler_rw_content_t, httpd_munin_rw_content_t,
httpd_bugzilla_rw_content_t. Many third party apps install html files in
directories that SELinux policy cannot predict. These directories have to be
labeled with a file context which httpd can access.

Allowing Access:

If you want to change the file context of video0 so that the httpd daemon can
access it, you need to execute it using semanage fcontext -a -t FILE_TYPE
'video0'.
where FILE_TYPE is one of the following: squirrelmail_spool_t, httpd_cache_t,
httpd_tmpfs_t, httpd_tmp_t, httpd_squirrelmail_t, httpd_cvs_rw_content_t,
httpd_git_rw_content_t, httpd_sys_rw_content_t, httpd_nagios_rw_content_t,
httpd_nutups_cgi_rw_content_t, httpd_squid_rw_content_t,
httpd_smokeping_cgi_rw_content_t, httpd_apcupsd_cgi_rw_content_t,
httpd_prewikka_rw_content_t, httpd_awstats_rw_content_t,
httpd_w3c_validator_rw_content_t, httpd_user_rw_content_t,
httpd_cobbler_rw_content_t, httpd_munin_rw_content_t,
httpd_bugzilla_rw_content_t. You can look at the httpd_selinux man page for
additional information.
