Question

I would like to change some code in one element X in gstreamer ugly plugin and rebuild and use it.

How I can do it?

I have gstreamer-0.10 and installed gstreamer-ugly plugin.
I would like to download only gstreamer0-10 ugly plugin code and change it and would like to use the new lib file. How I can do it?

unfortunately gstreamer-ugly depends on a lot of stuff in at least libgstreamer and plugins-base (if you’re using linux and your distro provides *-dev packages as debian/ubuntu does).

If you’re on debian you could use dpkg-buildpackage after checking out the source using apt-source. The big advantage here is that all the build dependencies can be easily installed.

The manual way will probably need you to first build all the other gstreamer packages have a close look on what ./configure tells you
I’m workin on debian and have already built gstreamer+plugins to backport the recent ones to ubuntu (although I’m not sure if I did it in a best-practice way 😉 )

/edit: I’ll try to cover the basic steps for ubuntu here:

• add the source repositories to apt (check the “source code” checkbox in the ubuntu software center’s “software sources” tool
• sudo apt-get install dpkg-dev devscripts
• sudo apt-get build-dep gst-plugins-ugly0.10
• apt-get source gst-plugins-ugly0.10
• change to the newly created gst-plugins-base* folder
• dpkg-buildpackage (and make sure it works)
• change the source to your needs
• you can rebuild it any time using dpkg-buildpackage (to simply see if it compiles make might be faster though). This creates a .deb file in the parent folder that you can simply install using dpkg -i
• If it’s a useful change you might want to get in touch with the gstreamer-devs 😉
