The code to put the PAR in metadata was already there, I just added debugging
;)

Putting the PAR has a lot of sense, because it allows players to scale the
display accordingly (and using the Flash APIs you can't get the PAR from the
actual encoded video data, so you need to rely on the textual stuff in the
metadata). The DAR doesn't make sense, right? Because you'd put in the DAR of
the machine on which you are encoding... And Flash can get the DAR of the
display that's playing the content, so that's not really necessary.

I haven't seen a player that makes use of other things than duration, PAR info
and width/height, but the filesize, for instance, might be useful for a
"Download this file" button, canSeekToEnd for a "seek to end" button, codec IDs
to tell the client that he's listening to Speex etc.

I think filesize, maybe the framerate and maybe codec info would be useful
(filesize in non-live case only).
