[vtk-developers] video decoding in VTK

[David Gobbi]

If you use Media Foundation you avoid most licensing issues.  I haven't
used it, but I found the ancient Video for Windows API to be
straightforward.  One issue with ffmpeg is that the API is still evolving,
so year-to-year maintenance of software that uses it is a concern.
