Download the patch file. If it is packed as a gz or tar.gz unpack it first. Then copy it to the motion source directory and issue the command (assuming the patch file is called filename_of_patch_file.diff)

Then re-build Motion and test the patch.

Ffmpeg supports the WebM and VP8 container and codec with the libvpx library. WebM is useful for viewing motion-triggered movies as HTML5 video elements.
