These build-dependencies are not obsolete. The reason that ovito doesn't 
link against these libraries is a typo in debian/rules:
         -DOVITO_VIDEO_OUPUT_SUPPORT=ON \
                         ^
This should read:
         -DOVITO_VIDEO_OUTPUT_SUPPORT=ON \

Additionally a build-dependency on libswscale-dev is missing.

Attached patch fixes these problems.

There might also be problems with other configuration options:
CMake Warning:
   Manually-specified variables were not used by the project:

     OVITO_BUILD_PLUGIN_ATOMVIZ
     OVITO_BUILD_PLUGIN_POVRAY
     OVITO_BUILD_PLUGIN_STDOBJECTS

Best regards,
Andreas
