Oiio has an ffmpeg reader but not a writer.  You would need to write out a
sequence of files and then convert it to h264 with something such as ffmpeg
in the commandline.  We use jpg or tiff sequences to do this depending on
the end quality required vs speed.  Usually 444 jpg set to 100% quality is
good enough.
