=== Troubleshooting [[UbuntuHelp:RealPlayer|RealPlayer]] for Linux ===
 +
==== [[UbuntuHelp:RealPlayer|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 <pre><nowiki>
 +
/usr/local/RealPlayer/realplay</nowiki></pre>
 +
Save and close the preference panel. 
 +
* To prevent the [[UbuntuHelp:MPlayer|MPlayer]] plugin from playing realaudio / video files, edit the plugin configuration file<pre><nowiki>
 +
gedit ~/.mplayer/mplayerplug-in.conf</nowiki></pre>
 +
Change or add the following three lines<pre><nowiki>
 +
enable-rm=0
 +
enable-smil=0
 +
enable-helix=0</nowiki></pre>
 +
* 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''' <pre><nowiki>
 +
rm $HOME/.mozilla/firefox/pluginreg.dat</nowiki></pre>
 +
or simply update the plugin file time <pre><nowiki>
 +
sudo touch /usr/lib/firefox/plugins/mplayerplug-in.so</nowiki></pre>
 +
* Alternatively you can reset all of your mime type associations by deleting the '''mimeTypes.rdf''' file <pre><nowiki>
 +
rm $HOME/.mozilla/firefox/dvibi9j3.default/mimeTypes.rdf</nowiki></pre>
 +
which is visible after enabling "Show Hidden Files".  The '''.default'''   
 +
directory will have a random alpha-numeric name.
 +
<br>
 +
* '''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: <pre><nowiki>
 +
  Helix DNA Plugin: RealPlayer G2 Plug-In Compatible (compatible; Totem)
 +
  File name: libtotem-complex-plugin.so
 +
  The Totem 2.16.2 plugin handles video and audio streams.</nowiki></pre>
 +
and <pre><nowiki>
 +
  Helix DNA Plugin: RealPlayer G2 Plug-In Compatible
 +
  File name: nphelix.so
 +
  Helix DNA Plugin: RealPlayer G2 Plug-In Compatible
 +
  version 0.4.0.572 built with gcc 3.2.0 on Sep 15 2005</nowiki></pre>
 +
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 <pre><nowiki>
 +
  /usr/lib/firefox/plugins </nowiki></pre>
 +
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 <pre><nowiki>
 +
  $ sudo rm -v /usr/lib/firefox/plugins/libtotem-complex-plugin.*</nowiki></pre>
 +
The plugin provided by Real''''''Player should now handle embedded real media.
 +
<br>
 +
* ''When I try to view embedded real media in Firefox 2, a dialog box appears saying the following, what gives?'' <pre><nowiki>
 +
  "Could not find an appropriate hxplay or realplay in the system path to use as an embedded player."</nowiki></pre>
 +
* 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 <pre><nowiki>
 +
  $ ln -s /usr/local/RealPlayer/realplay /usr/local/bin/realplay</nowiki></pre>
 +
Test your work: <pre><nowiki>
 +
  $ which realplay
 +
  $ /usr/local/bin/realplay</nowiki></pre>
 +
The plugin provided by Real''''''Player should now handle embedded real media.
 +
<br>
 +
* ''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. Note that some installations will only make symbolic links in the other '''''iceweasel''''' plugins folder. You need to copy them to the Firefox plugins folder:  <pre><nowiki>
 +
  $ sudo cp /usr/lib/iceweasel/plugins/nphelix.* /usr/lib/firefox/plugins/</nowiki></pre>
 +
==== [[UbuntuHelp:RealPlayer|RealPlayer]] freezes or playback is jerky  ====
 +
Many people complain that [[UbuntuHelp:RealPlayer|RealPlayer]] does not work right out of the box on Ubuntu. If you experience that try the following:
 +
* Install ALSA wrapper for OSS: <code><nowiki> $ sudo apt-get install alsa-oss </nowiki></code>
 +
* Start editing [[UbuntuHelp:RealPlayer|RealPlayer]] script: <code><nowiki> $ sudo gedit /usr/bin/realplay </nowiki></code> or <code><nowiki> $ sudo gedit /usr/bin/realplayer </nowiki></code> or <code><nowiki> $ sudo gedit /opt/RealPlayer </nowiki></code> depending how you installed the player
 +
* Find lines
 +
<pre><nowiki>
 +
if [ -n "$LD_PRELOAD" ]; then
 +
    echo "Warning: LD_PRELOAD=\"$LD_PRELOAD\""
 +
fi
 +
</nowiki></pre>
 +
and add these after them:
 +
<pre><nowiki>
 +
LD_PRELOAD="$LDPRELOAD:/usr/lib/libaoss.so"
 +
export LD_PRELOAD
 +
</nowiki></pre>
 +
* Save the changes, close the editor and start [[UbuntuHelp:RealPlayer|RealPlayer]].
 +
==== No sound (or freezes or playback or jerky) on 64 bit ====
 +
As above you need ALSA wrapper for OSS; but if you are running on 64 bit you need to get yourself the 32bit version since Realplayer is a 32 bit binary.
 +
* Grab the deb from: ftp://ftp.ubuntulinux.org/ubuntu/pool/universe/a/alsa-oss/alsa-oss_1.0.14-1ubuntu1_i386.deb
 +
* Create a new directory, cd it into that directory and then unpack it by doing:
 +
<pre><nowiki>
 +
    dpkg --fsys-tarfile alsa-oss_1.0.14-1ubuntu1_i386.deb | tar -xvf -
 +
</nowiki></pre>
 +
* Now you need to setup LD_PRELOAD and also LD_LIBRARY_PATH to point to whereever you unpacked that deb; I use a little wrapper script called playreal (chmod +x this file to make it runnable):
 +
<pre><nowiki>
 +
    #!/bin/sh
 +
    export LD_PRELOAD=/whereiunpacked/alsa-oss/usr/lib/libaoss.so
 +
    export LD_LIBRARY_PATH=/whereiunpacked/alsa-oss/usr/lib:$LD_LIBRARY_PATH
 +
    linux32 /myrealplayer/RealPlayer/realplay $*
 +
</nowiki></pre>
 +
* Now when I click on a .ram file and Firefox asks me what to run I tell it to run playreal.
 +
==== [[UbuntuHelp:RealPlayer|RealPlayer]] on Hardy ====
 +
I had problems with the alsa tricks on Hardy (Beta) and had to use Pulsaaudio; there is a program 'padsp' that you can
 +
use to set up a preload in the same way that alsa-oss does.
 +
For 64 bit I did a similar trick to above; I got the 32 bit version of pulseaudo-utils from the pool, unpacked it and then
 +
do:
 +
echo "Playreal called with $*" > /tmp/playreal.log
 +
export LD_PRELOAD=/whreiunpacked/usr/lib/libpulsedsp.so
 +
linux32 /myrealplayer/RealPlayer/realplay $*
 +
The audio works, but all the pixmap icons are broken. (penguin42)
 +
==== [[UbuntuHelp: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
 +
<pre><nowiki>
 +
Segmentation fault (core dumped)</nowiki></pre>
 +
This issue can be resolved by setting the environment variable GTK_IM_MODULE to the value xim (instead of scim).
 +
<pre><nowiki>
 +
export GTK_IM_MODULE=xim</nowiki></pre>
 +
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 [[UbuntuHelp:RealPlayer|RealPlayer]].

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/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:

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

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:

    • 

  •  Start editing RealPlayer script:  $ sudo gedit /usr/bin/realplay  or  $ sudo gedit /usr/bin/realplayer  or  $ sudo gedit /opt/RealPlayer  depending how you installed the player
    • 

  •  Find lines 


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

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 on Hardy


I had problems with the alsa tricks on Hardy (Beta) and had to use Pulsaaudio; there is a program 'padsp' that you can
use to set up a preload in the same way that alsa-oss does.
For 64 bit I did a similar trick to above; I got the 32 bit version of pulseaudo-utils from the pool, unpacked it and then
do:
echo "Playreal called with $*" > /tmp/playreal.log
export LD_PRELOAD=/whreiunpacked/usr/lib/libpulsedsp.so
linux32 /myrealplayer/RealPlayer/realplay $*
The audio works, but all the pixmap icons are broken. (penguin42)



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.
