[vtkusers] FFMPEG latest release in VTK

[Nicolas Rannou]

Hello,

so far, we have to use old versions of FFMPEG in order to make it usable 
with vtkFFMPEGWriter.cxx.
here is a solution to use FFMPEG latest release in VTK (note that we 
checked with ffmpeg folks and we only used LGPL components).

It has been tested on Linux and Mac so far.

You only need to replace:
  - FindFFMPEG.cmake in /VTK/CMake/
  - CMakeLists.txt in /VTK/IO/
  - vtkFFMPEGWriter.cxx in /VTK/IO/

Would it be possible to integrate it in VTK? Indeed, the previous FFMPEG 
working version is more than 2 years old and it would be nice to upgrade 
to the next versions. I am not sure if old versions of ffmpeg with vtk 
properly work on mac, and windows...
Since VTK is a visualization tool, easily recording video using FFMPEG 
would be very usefull!!!

Few days back, I also asked if it was possible to add:
SET( VTK_USE_FFMPEG_ENCODER "@VTK_USE_FFMPEG_ENCODER@" ) in 
/VTK/VTKConfig.cmake.in
indeed, it appears that this variable is missing.

Do I need to open a request/bug on Mantis for that?

Thanks,

Nicolas
