Yeah, the headache of converting everything back to 14-bit MLV or DNG was just too much for me. And, it was an excellent excuse for me to peek under the hood of this piece of software (and mlv_dump, where it al starts, of course). So, the two main reasons for giving this a shot was a) to play whatever I recorded without further conversion and b) streamline the workflow in creating an edit-ready ProRes copy straight off the MLV (then, mlrawviewer would be some sort of speedgrade).
Compiling: yes, that was perhaps the steepest part of the learning curve - I had never programmed in Python before (I'm a C,C++,C#,bash guy still getting irritated about the dumb indents) but I kept a record of what I did to get it going (perhaps the cmake-glfw3-xcode exercise was the worst of it all). I'll include a howto.txt, but can't verify if it is any good: once you've installed all the modules and tools, there's no going back without a full restore and retry. And there's that other thing with distributing ffmpeg as part of the package that I am not comfortable with....
I'll see about the bitbucket. What you describe about forking in one's own repository makes sense and should work.
