Help! I cannot get things right in Ubuntu Feisty even I installed w32codecs and all the Gstreamer codecs.
When I installed Totem-Gstreamer, I could hear something (Audio worked fine) for real video but no video was shown because RealVideo 3.0 plugin was not installed.
However, in Totem-Xine, no error sign was given. Video was shown but no audio was given out.
Worse, Mplayer.... nothing could give out because the device was "not available" (Cannot initialized the video....)
I wondered.... what should I do? I just want to get things worked in Totem at least......
Real player took a donkey years to load and sometimes even it loads,once I clicked on the properties (Options) of the player, the player close itself.......
Note: Other formats like wmv and mp3 worked seamlessly all right with these codecs installed.

I realize that you're trying to get RealVideo to decode with Totem, but have you tried the Helix player instead of RealPlayer? It's loads as quickly as Xine and Totem for me.

Ok... The thing "works" but sadly, it cant play rm files!!! (It load fast, true but nothing could be played by helix player) so it asked me to get Real Player. I get it , by rpm and converted into deb by alien and nothing is loaded (I do not understand that the system could not find the command real at all!!)
I tried xine too but xine could only show video but no audio given out.

You should try the proprietary Realplayer then. Helix is the open source version; it can play but doesn't stream real media files.

Sadly, VLC cannot show video but have audio (Same as Totem-Gstreamer) and from Synaptic, whether if the real player is updated version or inital version (BOTH 10.0.9-0fesity1 (feisty-commercial) AND 10.0.8-0ubuntu3 (stable) ) CANNOT be open as the updated version (10.0.9-0fesity1 (feisty-commercial)) will auto end processes: realplay and realplay.bin while the outdated version (10.0.8-0ubuntu3 (stable)) will never load at all (No player is shown but the process can be seen in the system monitor)with the processes: realplay and few same processes realplay.bin will never end process automatically too!
How should I do then?

I at last found that some drivers were configured wrongly in Mplayer. After correcting it, everything is fine in Mplayer. (At least Real Video can have both video and audio in Mplayer BUT in Totem still does not work as it should be instead of by having both video and audio, Totem works only audio for this few Real Videos.)
