There is no direct info in myth.  this is done by parsing the header
of the mpeg typically.  It is likely that an enhancement to
mythbackend will be needed to support this, considering the
limitations of the photobridge

This is stored in the SQL database.  There is a lot of info here, so
I'm not sure it's worthwhile to store the whole thing in roku's
memory.  perhaps just asking the backend to do the work would be
easiest (send a query asking for a file position for a specific frame
number (or ~PTS)
