+FFmpegwrapper
+~~~~~~~~~~~~~
+
+FFmpegWrapper is a small wrapper for the ffmpeg encoder. You can append
+Codec, Filters and other OptionStores to the FFmpeg class and then run the
+resulting command.
+
+>>> from ffmpegwrapper import FFmpeg, Input, Output, VideoCodec, VideoFilter
+>>> codec = VideoCodec('webm')
+>>> input_video = Input('old')
+>>> output_video = Output('new', videofilter, codec)
+>>> FFmpeg('ffmpeg', input_video, output_video)
+<FFmpeg ['ffmpeg', '-i', 'old', '-vcodec', 'webm', 'new']>
