Re: [FCP-L] MPEG-2 Playback Component - Busted in QT10?

Well, a quick lesson in the QT API is required.

MPEG Streamclip *should* be calling the QTKit API but it is more
likely calling the old QT C API (deprecated, ie do not use, except
there's still often no alternative). The Snow Leopard install includes
*all* the API from QT 7 plus QT X, so anything that worked on QT 7
should continue to work.

that it doesn't suggests there's something no-kosher in the way MPEG
Streamclip calls the QT API and that's why it's failing. I expect MPEG
streamclip will need to be "updated" to the appropriate API calls.

But test the MPEG-2 playback in the QT 7 player (in your Utilities
folder I believe or install from the Snow Leopard folder - you only
need the player, the API is already installed). If playback doesn't
work in the QT Player (7) it's unlikely to work in MPEG Streamclip and
is likely an incompatibility with Snow Leopard.
