This extensions provides an MPRIS interface for controlling Songbird through the Linux DBUS. It allows for changing tracks, volume and position, prev/next, play/pause/stop, as well as allows for retrieval of metadata on songs. This is my first Songbird extension and likely my last since they have discontinued support for Songbird on Linux, though there are still nightly builds available.
It began because I was wandering around the internet looking at Songbird extensions. At the time I think I was looking for ones that could be used for remote control and I came across DbusBird, but I was disappointed to see that it only supported reading basic metadata, and in the comments, someone mentioned MPRIS. I had no idea what that was, but I went and looked, since that's what one does when they are wandering the net :) MPRIS is a media player control interface standard thats runs on the Linux DBUS. A few months later, I was trying to decide on a project to work on and this came to mind. It seemed like fun, since I'd get to not only learn how to code a Songbird extension, but also learn how to contact DBus from C/C++. And thus it began.
I've linked to the files on the side here and put up a bunch of links that I found super helpful for Mozilla and dbus stuff. If you have any questions, take a look at the source and feel free to contact me.
