[Kdenlive-devel] development of a video editing server based on Kdenlive

Wed Oct 1 01:00:32 UTC 2014

Hello Volker:

Doing something like this gets complicated very quickly.  Especially in 
a 'public' environment where everybody wants their enhancement/feature 
included.  There's a lot of disciplines that must be integrated together 
as well as workflow and security issues.

That said, Kdenlive's integration requirements may be limited to 
precluding one from changing out of the 'root' directory when importing 
and rendering content.  By doing so, you can build a file based 
architecture that restricts the user to a specific directory that only 
contains 'their' content.

My suggestion would be to try to build such an environment and then 
approach modifying Kdenlive to preclude user-navigation outside of the 
root directory.
