gstreamer-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:

 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 }

Note: The types of audio streams in the mpeg files can vary!
 
gstreamer-complete
==================

This is a simple utility which provides custom bash completion when
typing gstreamer-launch commands. 

Simply run "gstreamer-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).

You can then enjoy context sensitive tab-completion of gstreamer-launch
commands.


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
=================

Allows you to check the properties of plugins and elements.

 ./gstreamer-inspect 
 
will show all the plugins available and the elements they contain.

 ./gstreamer-inspect <pluginname/elementname>

shows more info about the plugin/element.
