First jam update report! Been making pretty good progress so far.

Got ffmpeg opening videos and displaying them on the screen but single threaded and no audio yet.
You can seek the video and I'm using that to generate badly sized clip thumbnails.

I've also started work on the track editor and you can move clips around and chop them in half. I have also added undo/redo support for the clip editing which is all working nicely. You can't delete stuff yet.

I'm working on the sources panel on the left next which will display videos in a folder and allow you to drag them onto the track editor to add them to the film.

Once that bit is working the plan is to see if I can get the video panel to display the film you are editing, taking the clips etc into account!
