Hmmm, interesting. So is QuickTime 10.next going to drop support completely, or?

Ok. The posts on the Perian mailing list suggest that 10.9 is a no-go:

Here are some technical specifics:

Ah yes, I now understand :-)

Compiling with the --enable-vlc switch disabled is our default
behavior in TDF builds, so we should definitely be testing with that
off when trying to diagnose media playback. At least for now.

The future of audio/video playback on OS X looks pretty grim right
now. If Apple demotes the QuickTime framework in 10.9 and does not
mention a path forward for future OS revisions, then we should
definitely make plans to find an alternative for multimedia playback.

Multiple developers have spoken about problems with our attempts at
VLC integration, but VLC or FFmpeg/LibAV sound like our best options
going forward.
