Jokosher Summer of Code Projects
Mike @ 4:07 pm

This year we’re lucky enough to have three students working on Jokosher as part of the Google Summer of Code, two under GNOME and one under GStreamer.

Andi Miller

Andi is looking into making it possible to do collaborative editing tasks between multiple Jokosher instances, between Jokosher and Pitivi and potentially between Jokosher and a small remote control (so you can use your phone/MID to start Jokosher recording/playing without needing to be sat at your PC). The project is progressing well with some Jokosher information and events already being exposed via a dbus interface.

Pēteris Krišjānis

Pēteris is working on finishing up some old work to provide telepathy support within Jokosher and then further extending this to add support for telepathy tubes. This will make it very easy for users to record VoIP sessions within Jokosher and the tubes support will also tie-in with the collaborative editing project, allowing Andi to send dbus messages via telepathy connections to remote users. The most interesting use case from my perspective is for podcasters working over VoIP, in the scenario where both participants are using Jokosher it should be possible for them to carry out a standard VoIP call and then afterwards have the two Jokosher instances automatically synchronise a high quality recording of each participant’s side of the conversation; so while the VoIP call quality might not be perfect the final audio will sound as if they’re both in a studio together.

David Williams

David is attempting to add musical score editing support to Jokosher, allowing people to sketch out musical ideas that can be played back as MIDI instruments alongside normal recorded audio. He’s already made some good progress in creating a python GStreamer element that can output some simple MusicXML based on an internal model (which can then be rendered to MIDI via the musicxml2midi element), this will then later be connected to a score editing UI, with the potential for multiple interface types (traditional scores, guitar tablature, drum events, etc.).

So hopefully by the end of the summer we’ll not only have a number of very exciting new features but also three more core Jokosher developers :).
