The work required to change the multimedia packages that are "crippled"
is immense as most of these packages are there but most of them have
packman equivalents. In the case of blender the lack of ffmpeg support
is minor, unless you want to use it as a video editor which isn't it's
purpose, I suggested blender because I know from experience that the
video editing packages often need to be rebuilt on your own system to
get them to work properly whereas the blender development is extremely
active and it is used professionally by many. AFAIK the avi support uses
jpeg to create videos and it still has ogg theora support.
I just dislike "cripple" scripts from a maintainers point of view. The
mjpegtools one ate the freshly downloaded tarball because it had a hard
coded version number. This turns an otherwise easy update into a time
consuming one and mjpegtools libraries are needed by quite a few key
packages so dropping it isn't an option. Dropping xine-libs is an option
because it has other replacements but not for 11.4.
