-gstreamer-launch
+gst-launch
================
This is a tool that will construct pipelines based on a command-line
A simple commandline looks like:
- gstreamer-launch disksrc location=music.mp3 ! mad ! osssink
+ gst-launch filesrc 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
+ gst-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
+ gst-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
+ gst-launch gnomevfssrc location=music.mp3 ! mad ! osssink
+ gst-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
+ gst-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
+ gst-launch filesrc location=music.mp3 ! mad ! vorbisenc ! filesink location=music.ogg
And then we can play that file with:
- gstreamer-launch disksrc location=music.ogg ! vorbisdec ! osssink
+ gst-launch filesrc location=music.ogg ! oggdemux ! vorbisdec ! audioconvert ! osssink
Some other useful pipelines are..
Plays wav files (currently there are no wav encoders):
- gstreamer-launch disksrc location=music.wav ! parsewav ! osssink
+ gst-launch filesrc location=music.wav ! wavparse ! 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
+ gst-launch filesrc location=music.wav ! wavparse ! vorbisenc ! filesink location=music.ogg
+ gst-launch filesrc location=music.wav ! wavparse ! mpegaudio ! filesink 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
+ gst-launch cdparanoia ! mpegaudio ! filesink location=cd.mp3
-You can toy around with gstreamer-inspect to discover the settings for

Record sound from your sound input and encode it into an ogg file:
- gstreamer-launch osssrc ! vorbisenc ! disksink location=input.ogg
+ gst-launch osssrc ! vorbisenc ! filesink location=input.ogg
-gstreamer-launch not only handles audio but video as well:
+gst-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 }
+ gst-launch filesrc location=video.mpg ! mpegdemux video_00! { queue ! mpeg2dec ! sdlvideosink }
+ gst-launch filesrc location=video.mpg ! mpegdemux audio_00! { queue ! mad ! osssink }
+
+for mpeg1 with both audio and video (for glib2):
+
+ gst-launch filesrc location=video.mpg ! mpegdemux name=demux video_00! { queue ! mpeg2dec ! sdlvideosink } demux.audio_00! { queue ! mad ! osssink }
+
+for mpeg1 with both audio and video (for gtk1.2, the shim doesn't handle the 'name' property yet):
+
+ gst-launch filesrc location=video.mpg ! mpegdemux video_00! { queue ! mpeg2dec ! sdlvideosink } mpegdemux0.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 }
+ gst-launch filesrc location=video.mpeg ! mpegdemux video_00! { queue ! mpeg2dec ! sdlvideosink }
+ gst-launch filesrc location=video.mpeg ! mpegdemux private_stream_1.0! { queue ! a52dec ! osssink }
+
+for mpeg2 with both audio and video (glib2):
+
+ gst-launch filesrc location=video.mpg ! mpegdemux name=demux video_00! { queue ! mpeg2dec ! sdlvideosink } demux.private_stream_1.0! { queue ! a52dec ! osssink }
Note: The types of audio streams in the mpeg files can vary!

-gstreamer-complete
+
+For an avi file (DivX, mjpeg,...)
+
+ gst-launch filesrc location=video.avi ! avidecoder video_00! { queue ! sdlvideosink } avidecoder0.audio_00! { queue ! osssink }

+gst-complete
==================
This is a simple utility which provides custom bash completion when
-typing gstreamer-launch commands.
+typing gst-launch commands.
-Simply run "gstreamer-compprep" as root to build the registry of completions,
+Simply run "gst-compprep" as root to build the registry of completions,
and then put, in your .bashrc,
-"complete -C gstreamer-complete gstreamer-launch"
-(ensuring that gstreamer-complete is on your path).
+"complete -C gst-complete gst-launch"
+(ensuring that gst-complete is on your path).
-You can then enjoy context sensitive tab-completion of gstreamer-launch

-gstreamer-register
-==================
-
-This tool will perform an introspection on all available plugins and will
-create a registry file in /etc/gstreamer/reg.xml. Startup time will be
-much faster since the gstreamer core doesn't have to bring all the plugins
-files into memory at startup. As with gstreamer-compprep you need to run this
-as root for it too work correctly.
-
-gstreamer-inspect
+gst-inspect
=================
Allows you to check the properties of plugins and elements.
- ./gstreamer-inspect
+ ./gst-inspect
will show all the plugins available and the elements they contain.
- ./gstreamer-inspect <pluginname/elementname>
+ ./gst-inspect <pluginname/elementname>
shows more info about the plugin/element.
+
+gst-xmlinspect
+=================
+
+Dump properties of plugins and elements in an xml format. You can
+transform the xml to something else with an appropriate stylesheet.
+
+ ./gst-xmlinspect <elementname> | xsltproc xml2text.xsl -
