<command>gstreamer-config</command> is a script to get information about the installed

A simple <filename>Makefile</filename> will contain something like:
|
|
<programlisting>
|
|
CC = gcc
|
|
|
|
helloworld2: helloworld2.c
|
|
$(CC) -Wall `gstreamer-config --cflags --libs` helloworld2.c -o helloworld2

clean:
|

<para>
|
|
<command>gstreamer-register</command> is used to rebuild the database of plugins.
|
|
It is used after a new plugin has been added to the system. The plugin database
|
|
can be found in <filename>/etc/gstreamer/reg.xml</filename>.

<para>
|
|
This is a tool that will construct pipelines based on a command-line
|
|
syntax.
|

</para>
|
|
<para>
|
|
A simple commandline looks like:
|
|
|
|
<screen>
|
|
gstreamer-launch disksrc hello.mp3 ! mp3parse ! mpg123 ! audiosink-oss
|
|
</screen>
|
|
|
|
A more complex pipeline looks like:
|
|
|
|
<screen>
|
|
gstreamer-launch disksrc redpill.vob ! css-descramble ! private_stream_1.0 ! \
|
|
(ac3parse ! ac3dec ! audiosink) video_0 ! (mpeg2dec ! videosink)
|
|
</screen>
