I would like to provide the functionality of a "video export" from
within an activity I am working on.  I'm starting with a png for each
frame of the video and would like to do something like:

png2yuv -I p -f 25 -j /tmp/*.png >my.yuv
ffmpeg2theora --optimize my.yuv

Could someone enlighten me on how I could achieve this from the
libraries available on the XO?

Thanks.

Perhaps examination of the following Python-based convertor would  
prove beneficial.
