so can I ask -

what would it take to write Dirac into single file MXF or QT as =
containers ? seems to me that using established well known containers =
would mean only needing to add the codec into the right place in your =
system and then you could easily r/w the files and exchange them. no =
doubt if Ogg container only had to live on my machine it would be fine, =
but exchange becomes more of an issue.  I'd rather see a standard =
documented container with a common codec than yet another new container =
format.  FWIW, before the win users say they don't want QT as a =
container, please know that you don't have to have QT installed on your =
machine for apps to be able to r/w it. Adobe wrote mediacore as an =
underlying lib that does direct I/O on several flavors of QT so that you =
can access QT files w/o having QT the app & libs installed on your =
machine. It also means a fast / mean / lean way to do QT file I/O =
without the limitations of PC QT32.
