[PythonicAlpha]

The idea is good, I remember that other projects like Avidemux integrate QtScript or Spidermonkey for scripting.

Has anybody experience, how the integration overhead is? Looks as this could be integrated very simply. The problem is, that it is in alpha stage and how stable and complete is it currently?

Integration is very easy (check out the examples in their git repo), but this is still alpha quality software - there are known limitations, e.g. the one I ran into is that a large JS expression involving function calls might make Duktape run out of bytecode registers.
