This has undergone significant changes in implementation and design in 0.11, and we're just not going to backport this to 0.10, so let's just remove it again and continue to fix this up in master/1.0. |

gst-launch ================ This is a tool that will construct pipelines based on a command-line syntax. The syntax is rather complex to enable all the features I want it to have, but should be easy to use for most people. Multi-pathed and feedback pipelines are the most complex. A simple commandline looks like: gst-launch filesrc location=music.mp3 ! mad ! osssink This plays an mp3 music file music.mp3 using libmad, and: gst-launch filesrc location=music.mp3 ! mp3parse ! mpg123 ! osssink 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 gst-launch commands. 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 gst-launch commands. 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 -
