SWF to Mov using FFMPEG
===

I am trying to use ffmpeg to convert an swf file to a mov file. When this happens I only get the audio. If I do 

ffplay -stats mine.swf

then I just get the audio and no video. I dont think the swf codec in installed. I find this confusing because it says that it is present in the installation according to the documentation.

Does anyone know how I can do this? Can I download another codec?

Thanks
