Media Viewers: ffmpeg conversion options -vpre medium

[GoogleCodeExporter]

In file config/alfresco/extension/org_sharextras_video-transform-context.xml 
there is a conversion option -vpre medium.
This means that there needs to be a file medium.ffpreset available to ffmpeg. I 
did not have that on my install, thus conversion fails.

Its not hard to create this file yourself, but we still need to
- provide a sample file for medium.ffpreset, especially if this file has 
options that are tested to be good for alfresco previews. Update the 
documentation to explain this file
or
- remove this from default options to that the conversion works out of the box

My environment:
Installed ffmpeg with homebrew on my mac os. So the file medium.ffpreset may be 
standard in other ffmpeg installs and that this is unique to ffmpeg via 
homebrew.
