How do I dis/enable movie-making support in librtk?
Included with librtk is the ffmpeg library, which can be used to produce MPEG animations. By default, ffmpeg support will be compiled into librtk. However, ffmpeg does not build everywhere (notably, it seems to fail on Sparc/Solaris). If during the build, ffmpeg/configure fails, then you should disable ffmpeg support. To do so, pass –disable-libavcodec to configure before building librtk.
