Hi everyone, I've added a new blog post detailing what I've been up to the past week. Here's the contents of the post so you don't have to fire up a browser :P So the Summer of Code has officially begun and I’ve been doing a few things this week (as well as finishing my final exam(yay!)). I’ve been working on writing a GStreamer source element for the MusicXML generator that will allow me to send the generated MusicXML to a GStreamer Pipeline. FIlesrc isn’t suitable as I don’t want to load the file every time I want the MusicXML to play. I’ve been having a little difficulty getting the Source Element to work as there isn’t much information on how the Python GStreamer bindings are used in the context of creating elements. I found a post on the Pitivi wiki that explains some of the basics but isn’t solely based on Source Elements. I’ve been reading the C tutorials for GStreamer as well to try and learn as much as I can about GStreamer and how it interacts with the plugins, which should help me understand how to get things working better. So most of this week has been spent reading Tutorials and Source Code for other GStreamer Source Elements (like audiotestsrc) and trying to transfer those concepts over to Python. I’m nearly finished with the Source Element I just need to figure out how I can pass the data buffer back out into the pipeline, which is the only part I’ve really had issue with. Hopefully I’ll get that done as soon as possible and I can start working on integrating what I have so far into the Jokosher code base and at some point soon starting on a basic UI.
