Summary0004719: vtkFFMPEGWriter needs porting from use of img_convert to sws_scale
Descriptionimg_convert, currently used in vtkFFMPEGWriter is a deprecated function. If the flag --enable-swscaler is included in the build for ffmpeg, then img_convert is not included in the distribution.

Note that this seems to be an either or kind of situation, so the patch I have uploaded will convert to using sws_scale, but will break the writer if the avcodec library uses img_convert (I believe)


Also, the cmake configuration files need to be modded to include -lswscale as a dependent library

Note, this deprecation hit me with the most recent build of ffmpeg libraries from debian-multimedia.org

We need to find a different workaround for the lack of img_convert(). Enabling the swscaler portion of ffmpeg makes the library GPL. We need to use routines from within an option set that keeps the library LGPL, or anything that uses vtkFFMPEGWriter will become GPL.

Lovely - can't we all just get along?
