gstreamer video streaming

Question

I have executed AudioPlayer.java example posted by open source community link

Audio Player Tutorial

I got the following exception

Exception in thread "main" java.lang.IllegalArgumentException: No such Gstreamer factory: playbin
 at org.gstreamer.ElementFactory.makeRawElement(ElementFactory.java:180)

Can anyone give me the solution for this problem?

Thanks in advance.

Answer 1

This is due to path variables being not set correctly.

If you are using NetBeans 6.9+ then follow these steps

Note: I am assuming that you are working in Windows XP/Vista/7, etc.

1. Create a new project
2. Download gstreamer-java-1.4.jar and jna-3.2.4.jar
3. Add jna and jar files to library of the created NetBeans Project
4. Download GStreamer-WinBuilds-GPL-x86.msi from the following OSS website http://code.google.com/p/ossbuild/ For commercial use their LGPL version. Make sure your environmental variable with prefix OSS_ is set in the environmental variables in Windows. You can access this by right clicking "My Computer" -> "Advanced"

5. In NetBeans Right click "project" -> "properties". Go to "VM Options" in "run" type

   -Djna.library.path="[your gstream OSS build classpath1 to bin]:[your gstream OSS build classpath2 to lib]"
   

   Similarly you may need to provide classpath to java here too

   -Djava.library.path="[your gstream OSS build classpath1 to bin]:[your gstream OSS build classpath2 to lib]"
   

   Note: You must know where your OSS gstreamer dlls are installed. Typically under "OSSbuild" directory in "Program Files".

6. You may have to reboot
7. Run and Enjoy Gstreamer!

Answer 2

You need change

PlayBin playbin = new PlayBin("AudioPlayer");

for

PlayBin2 playbin = new PlayBin2("AudioPlayer");

with the version 1.5
