-gstreamer-launch
+gst-launch
================
This is a tool that will construct pipelines based on a command-line
A simple commandline looks like:
-./launch disksrc demo.mp3 | mp3parse | mpg123 | osssink
+ gst-launch filesrc 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| \
-(ac3parse | ac3dec | audioink-oss) video_0| (mpeg2dec | videosink)
+ gst-launch filesrc location=music.mp3 ! mp3parse ! mpg123 ! osssink
-gstreamer-complete
+Plays and mp3 music file using mpg123
+
+You can also stream files over http:
+
+ gst-launch httpsrc location=http://domain.com/music.mp3 ! mad ! osssink
+
+And using gnome-vfs you can do the same with:
+
+ 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:
+
+ gst-launch gnomevfssrc location=smb://computer/music.mp3 ! mad ! osssink
+
+Here we convert a Mp3 file into an Ogg Vorbis file:
+
+ gst-launch filesrc location=music.mp3 ! mad ! vorbisenc ! filesink location=music.ogg
+
+And then we can play that file with:
+
+ gst-launch filesrc location=music.ogg ! oggdemux ! vorbisdec ! audioconvert ! osssink
+
+Some other useful pipelines are..
+Plays wav files (currently there are no wav encoders):
+
+ gst-launch filesrc location=music.wav ! wavparse ! osssink
+
+Converts wav files into mp3 and ogg files:
+
+ 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:
+
+ gst-launch cdparanoia ! mpegaudio ! filesink location=cd.mp3
+
+You can toy around with gst-inspect to discover the settings for
+cdparanoia to rip individual tracks
+
+Record sound from your sound input and encode it into an ogg file:
+
+ gst-launch osssrc ! vorbisenc ! filesink location=input.ogg
+
+gst-launch not only handles audio but video as well:
+For mpeg1 files (video and audio streams respectively):
+
+ 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):
+
+ 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!
+
+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" 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).
+Simply run "gst-compprep" as root to build the registry of completions,
+and then put, in your .bashrc,
+"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

+
+gst-inspect
+=================
+
+Allows you to check the properties of plugins and elements.
+
+ ./gst-inspect
+
+will show all the plugins available and the elements they contain.
+
+ ./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 -
