|

\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 filesrc location=music.mp3 ! mad ! osssink
|
|
|
|
This plays an mp3 music file music.mp3 using libmad, and:
|
|
|
|
gstreamer\-launch filesrc 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 filesrc location=music.mp3 ! mad ! vorbisenc ! disksink location=music.ogg
|
|
|
|
Or converting from mp3 to Flac:
|
|
gstreamer\-launch filesrc location=claptrap.mp3 ! mad ! flacenc ! disksink location=test.flac
|
|
|
|
And then we can play that file with:
|
|
|
|
gstreamer\-launch filesrc location=music.ogg ! vorbisdec ! osssink
|
|
|
|
Some other useful pipelines are..
|
|
Plays wav files (currently there are no wav encoders):
|
|
|
|
gstreamer\-launch filesrc location=music.wav ! parsewav ! osssink
|
|
|
|
Converts wav files into mp3 and ogg files:
|
|
|
|
gstreamer\-launch filesrc location=music.wav ! parsewav ! vorbisenc ! disksink location=music.ogg
|
|
gstreamer\-launch filesrc location=music.wav ! parsewav ! mpegaudio ! disksink location=music.mp3
|
|
|
|
Play mpeg movie with the aasink:
|
|
gstreamer\-launch filesrc location=JB_FF9_TheGravityOfLove.mpg ! mpegdemux video_00! { queue ! mpeg2dec ! aasink }
|
|
|
|
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 mpeg video files (here outputing to aasink) :
|
|
|
|
gstreamer\-launch filesrc location=JB_FF9_TheGravityOfLove.mpg ! mpegdemux video_00! { queue ! mpeg2dec ! aasink }
|
|
|
|
For vob files (here outputting image to sdlvideosink):
|
|
gstreamer\-launch filesrc location=/flflfj.vob ! mpegdemux video_00! { queue ! mpeg2dec ! sdlvideosink }
|
|
|
|

|
|
create a PIPELINE\-DESCRIPTION.
