The Shotcut Windows build is cross-compiled on an Ubuntu host. The main difficulty with the Windows build (manually or automated cross-compile) is dependencies. About half of them are pre-built, usually by the upstream project, but I have manually cross-compiled a few things. The other half are built by the script that comes with shotcut source where I had to figure out the cross-compile incantations required for each package it builds. > build that environment for myself.

There's obviously tons of How good is the video embed working? I was not happy with some of the quirks I observed with embedding the SDL video window on Windows when I tried it in Shotcut. So, I switched to QGLWidget and never looked back. Also, you really want OpenGL as a display method to best utilize the GPU-based image processing in the next version of MLT. However, to get the OpenGL display method working in Python requires some enhancement to the SWIG definition to support Mlt::Event (see RubyListener in src/swig/mlt.i). > subtleties, but the python-binding is already established on linux - it > comes down to stuff that resembles build-errors (paths, stdlib variations > etc).

If you want to try and help, then I can provide a few things to help you prepare the linux mingw build environment (packages to install and a few tarballs of pre-built dependencies). > On Thu, Feb 14, 2013 at 12:18 AM, Dan Dennedy <d...@dennedy.org> wrote: >> >> On Wed, Feb 13, 2013 at 2:44 PM, Benjamin Bruheim <gro...@gmail.com> >> wrote: >> > Hey, >> > >> > I wonder if shotcut could package the bindings.
