vtkFFMPEGWriter needs porting from use of img_convert to sws_scale
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
img_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
