About RealPlayer

RealPlayer is a media player originally developed by Real'Networks way back in 1995. It supports a number of audio and video codecs such as realaudio, realvideo 10, mp3, ogg vorbis and theora, h263, and AAC. RealPlayer for Linux is based on the open-source Helix Player which can be found at the Helix Community Website. https://help.ubuntu.com/community/IconsPage??action=AttachFile&do=get&target=eyes.png Please NOTE': Real'Player is proprietary software and is not supported by the Ubuntu community.

Installing RealPlayer

Install RealPlayer from Canonical's Commercial Repositories

Add Canonical's Commercial Repositories to your system:

• Ubuntu 6.06 «Dapper Drake»:

deb http://archive.canonical.com/ubuntu dapper-commercial main

• Ubuntu 6.10 «Edgy Eft»:

deb http://archive.canonical.com/ubuntu edgy-commercial main

• Ubuntu 7.04 «Feisty Fawn»:

If you need help with adding the repository, see Adding Canonical Commercial Repositories on Ubuntu or Kubuntu on the Repositories wiki pages.

• Once the repository has been added, select Add/Remove... from the Applications menu.
• To find Real'Player more easily, type Real'Player into the search box at the top. Check the box next to the search result and press OK
• To uninstall Real'Player, return to Add/Remove Applications, uncheck the box next to Real'Player, then press OK.

The package in the Commercial repository is called realplay.

Troubleshooting RealPlayer for Linux

RealPlayer and Firefox 2

• External Protocol Handling': I want Real'Player to handle Real'Audio and Real'Video files and streams (file extensions .ra, .rm, .rv, .ram, .smil) as well as the rtsp network protocol, but Firefox wants to open these files and links with the Totem player. What to do?
  • To make Firefox 2 call Real'Player for realaudio / video files, go to "Edit > Preferences > Content > File Types > Manage...". Select the "real audio" file type and click "Change action.." Check the setting for "Open with the default application" (unless you have made changes to this setting previously, it will probably say Totem). If you want the file to open with an external program other than the default (like Real'Player), select "Open with this application" - you will then be prompted to select an application. Navigate to the start-up script for Real'Player ("realplay") located in the "Real'Player" program folder. The location will differ depending on the installation method you have chosen. For a typical install using the installer from the Real'Networks web site, it will be

/usr/local/[[UbuntuHelp:RealPlayer|RealPlayer]]/realplay

Save and close the preference panel.

• To prevent the MPlayer plugin from playing realaudio / video files, edit the plugin configuration file

gedit ~/.mplayer/mplayerplug-in.conf

Change or add the following three lines

enable-rm=0
enable-smil=0
enable-helix=0

• To make Firefox 2 use Real'Player for rtsp streams embedded in web page links, close Firefox and open the gconf editor' from the Applications menu. Navigate to "desktop > gnome > url-handlers > rtsp". Check the value for "command" - it will probably read totem "%s". Change the entry to read realplay "%s" and close gconf editor. Note: make sure that a symbolic link of the "realplay" start-up script is in your system path, otherwise you'll need to enter the full path to "realplay" in the gconf entry. See below.
• Note: Firefox will only evaluate the mime types that the plugin supports either when such plugin is updated or when $HOME/.mozilla/firefox/pluginreg.dat is missing. Therefore when you change any option you also need to either remove pluginreg.dat

rm $HOME/.mozilla/firefox/pluginreg.dat

or simply update the plugin file time

sudo touch /usr/lib/firefox/plugins/mplayerplug-in.so

• Alternatively you can reset all of your mime type associations by deleting the mimeTypes.rdf file

 
rm $HOME/.mozilla/firefox/dvibi9j3.default/mimeTypes.rdf

which is visible after enabling "Show Hidden Files". The .default directory will have a random alpha-numeric name.

• Plugin Handling: Firefox 2 won't play real media embedded in web pages. What's up with that?
  • Check whether the Real'Player plugin is installed correctly. Type about:plugins' into the Firefox address bar. You will see a page with details of all currently installed plugins. Search for plugins that will handle real audio or real video files and streams. If you cannot find any, there is a problem with your plugin installation. Read on. More likely however, you will find at least two similarly named plugins that claim to handle real media:

Helix DNA Plugin: [[UbuntuHelp:RealPlayer|RealPlayer]] G2 Plug-In Compatible (compatible; Totem)
File name: libtotem-complex-plugin.so
The Totem 2.16.2 plugin handles video and audio streams.

and

Helix DNA Plugin: [[UbuntuHelp:RealPlayer|RealPlayer]] G2 Plug-In Compatible
File name: nphelix.so
Helix DNA Plugin: [[UbuntuHelp:RealPlayer|RealPlayer]] G2 Plug-In Compatible
version 0.4.0.572 built with gcc 3.2.0 on Sep 15 2005

The first entry is a plugin for the Totem player; the second entry is the actual Real'Player plugin. Firefox will try to use the first plugin it finds that claims to handle a given file type. Unfortunately, the Totem plugin won't play real media files. Now, if we close the browser and look into the plugins folder of Firefox 2, located at

/usr/lib/firefox/plugins 

we can see that most plugins offer a pair of files named foo.so and foo.xpt, and that they use symbolic links that point to the original installation locations. Therefore, we can safely remove the symbolic links to the non-functional Totem real media plugin

$ sudo rm -v /usr/lib/firefox/plugins/libtotem-complex-plugin.*

The plugin provided by Real'Player should now handle embedded real media.

• When I try to view embedded real media in Firefox 2, a dialog box appears saying the following, what gives?

"Could not find an appropriate hxplay or realplay in the system path to use as an embedded player."

• Firefox is telling you that it cannot find an instance of the "realplay" start-up script for Real'Player in the system path. Close the browser, open a Terminal and create a symbolic link in your system path that points at the "realplay" script. An example of an appropriate location for your symbolic link would be

$ ln -s /usr/local/[[UbuntuHelp:RealPlayer|RealPlayer]]/realplay /usr/local/bin/realplay

Test your work:

$ which realplay
$ /usr/local/bin/realplay

The plugin provided by Real'Player should now handle embedded real media.

• How can I verify that the Real'Player plugin for Firefox is properly installed?
  • Enter about:config into the Firefox address bar. You will see a large list of configurable options for the Firefox browser. In the search bar, enter "plugin". Look for an entry named plugin.expose_full_path and set its value to true. (This will allow you to see the full path to the plugins in the next step.)
  • Enter about:plugins' into the browser adress bar. You should now see a list of installed plugins along with some additional information and their locations in the file system. If you can see the Helix DNA Plugin: Real'Player G2 Plug-In Compatible plugin and the path to a file named nphelix.so is given, the plugin is installed correctly.
  • Another way to check is to look for the file pair nphelix.so and nphelix.xpt in the Firefox plugins folder. Depending on the way Real'Player was installed on your system, the plugins folder should either hold copies of or symbolic links to the plugin file pair; either should be ok.

RealPlayer freezes or playback is jerky

Many people complain that RealPlayer does not work right out of the box on Ubuntu. If you experience that try the following:

• Install ALSA wrapper for OSS: $ sudo apt-get install alsa-oss
• Start editing RealPlayer script: $ sudo gedit /usr/bin/realplayer or $ sudo gedit /opt/[[UbuntuHelp:RealPlayer|RealPlayer]] depending how you installed the player
• Find lines

if [ -n "$LD_PRELOAD" ]; then
echo "Warning: LD_PRELOAD=\"$LD_PRELOAD\""
fi

and add these after them:

LD_PRELOAD="$LDPRELOAD:/usr/lib/libaoss.so"
export LD_PRELOAD

• Save the changes, close the editor and start RealPlayer.

RealPlayer and SCIM

RealPlayer might not start if using SCIM as the default input method. When trying to launch from the terminal one gets the error message

Segmentation fault (core dumped)

This issue can be resolved by setting the environment variable GTK_IM_MODULE to the value xim (instead of scim).

export GTK_IM_MODULE=xim

After typing this in a terminal, RealPlayer can be started from this terminal. In order to make this setting the default, one can for example write a small shell script which first sets the above environment variable and then launches the RealPlayer.
