You can do this by making use of the MovieExportDoUserDialog() and
ConvertMovieToFile() functions. It is propably more appropriate to ask these
questions on the mailinglists of Apple.

You can easily call those (command line) tools from your program by creating
a new (hidden) process in which you execute the tool in question.
If you can do it the above way (which is no longer a *live* streaming
scenario), you'll no longer need a DirectShow renderer filter for doing the
packetization (as described in your previous mail).
Kind regards,
Wesley
