.LP
\fBgstreamer\-launch\fR is a tool that is used to build and run a basic <fl>GStreamer\fR pipeline.
A simple commandline looks like:
gstreamer\-launch disksrc location=music.mp3 ! mad ! osssink
This plays an mp3 music file music.mp3 using libmad, and:
gstreamer\-launch disksrc location=music.mp3 ! mp3parse ! mpg123 ! osssink
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 }
.

create a PIPELINE\-DESCRIPTION.
