User:Dan Nessett/Technical/Notes on OggHandler

Installing OggHandler

• php-pear must be installed. Try:

yum list php-pear

• ffmpeg is required.
• Change LocalSettings.php:

$wgFileExtensions = array( 'png', 'gif', 'jpg', 'jpeg', 'ogg', 'ogx', 'oga', 'ogv', 'svg' );

$wgMediaHandlers = array(
    'jpeg' => 'BitmapHandler',
    'image/jpeg' => 'BitmapHandler',
    'image/png' => 'BitmapHandler',
    'png' => 'BitmapHandler',
    'image/gif' => 'BitmapHandler',
    'gif' => 'BitmapHandler',
    'image/x-ms-bmp' => 'BmpHandler',
    'image/svg+xml' => 'SvgHandler',
    'image/svg' => 'SvgHandler',
    'image/vnd.djvu' => 'DjVuHandler',
    'application/ogg' => 'OggHandler',
    'ogx' => 'OggHandler',
    'video/ogg' => 'OggHandler',
    'ogv' => 'OggHandler',
    'audio/ogg' => 'OggHandler',
    'oga' => 'OggHandler',
    'ogg' => 'OggHandler'
);

• Modify mime.types in $IP/includes as follows:

application/ogg ogg ogm ogx oga ogv

audio/ogg ogg oga

audio/x-ogg ogg oga

video/ogg ogm ogg ogv

video/x-ogg ogm ogg ogv

• To test the installation, you need to have java installed on the browser. For Firefox, this is a real pain. You have to softlink the appropriate java library files to /usr/lib/mozilla/plugins. The exact libraries depends on which jre you have installed. For my private CentOS 5.4 installation it is:

usr/lib/mozilla/plugins/libjavaplugin_oji.so -> /usr/java/jre1.6.0_19/plugin/i386/ns7/libjavaplugin_oji.so
usr/lib/mozilla/plugins/libnpjp2.so -> /usr/java/jre1.6.0_19/lib/i386/libnpjp2.so

• getting the following error on test wiki (using latest development version of OggHandler extension):
