 A simple commandline looks like:
 
- ./launch disksrc demo.mp3 | mp3parse | mpg123 | osssink
+ gstreamer-launch disksrc location=music.mp3 ! mad ! osssink
 
-A more complex pipeline looks like:
+This plays an mp3 music file music.mp3 using libmad, and:
 
- ./launch disksrc redpill.vob | css-descramble | private_stream_1.0| \
+ gstreamer-launch disksrc location=music.mp3 ! mp3parse ! mpg123 ! osssink
-  (ac3parse | ac3dec | audioink-oss) video_0| (mpeg2dec | videosink)
 
+Plays and mp3 music file using mpg123
+
+You can also stream files over http:
+
+ gstreamer-launch httpsrc location=http://domain.com/music.mp3 ! mad ! osssink
+
+And using gnome-vfs you can do the same with:
+
+ gstreamer-launch gnomevfssrc location=music.mp3 ! mad ! osssink
+ gstreamer-launch gnomevfssrc location=http://domain.com/music.mp3 ! mad ! osssink
+
+And too play the same song with gnome-vfs via smb:
+
+ gstreamer-launch gnomevfssrc location=smb://computer/music.mp3 ! mad ! osssink
+
+Here we convert a Mp3 file into an Ogg Vorbis file:
+
+ gstreamer-launch disksrc location=music.mp3 ! mad ! vorbisenc ! disksink location=music.ogg
+
+And then we can play that file with:
+
+ gstreamer-launch disksrc location=music.ogg ! vorbisdec ! osssink
+
+Some other useful pipelines are..
+Plays wav files (currently there are no wav encoders):
+
+ gstreamer-launch disksrc location=music.wav ! parsewav ! osssink
+
+Converts wav files into mp3 and ogg files:
+
+ gstreamer-launch disksrc location=music.wav ! parsewav ! vorbisenc ! disksink location=music.ogg
+ gstreamer-launch disksrc location=music.wav ! parsewav ! mpegaudio ! disksink location=music.mp3
+
+You can also use lame for mp3 encoding if you have it installed, it does a 
+much better job than mpegaudio.
+
+Rips all songs from cd and saves them into a mp3 file:
+
+ gstreamer-launch cdparanoia ! mpegaudio ! disksink location=cd.mp3
+
+You can toy around with gstreamer-inspect to discover the settings for 
+cdparanoia to rip individual tracks
+
+Record sound from your sound input and encode it into an ogg file:
+
+ gstreamer-launch osssrc ! vorbisenc ! disksink location=input.ogg
+
+gstreamer-launch not only handles audio but video as well:
+For mpeg1 files (video and audio streams respectively):
+
+ gstreamer-launch disksrc location=video.mpg ! mpeg1parse video_00! queue ! { mp1videoparse ! mpeg_play ! sdlvideosink }
+ gstreamer-launch disksrc location=video.mpg ! mpeg1parse audio_00! queue ! { mad ! osssink }
+
+For mpeg2 files (video and audio streams respectively):
+ 
+ gstreamer-launch disksrc location=video.mpeg ! mpeg2parse video_0! queue ! { mpeg2dec ! sdlvideosink }
+ gstreamer-launch disksrc location=video.mpeg ! mpeg2parse private_stream_1.0! queue ! { ac3dec ! osssink }
+
+Note: The types of audio streams in the mpeg files can vary!
