Yes, it transcodes files on the fly for the formats and codecs that were previously supported in QT 7. >> If a user wants read/export support for codecs that were previously >> supported by Apple, then they can still download QuickTime 7 (for the >> moment at least, but that'll be pulled soon enough no doubt). > If QuickTime 7 is EOL, or is only available on versions of OSX that we > are moving away from, then let's ignore that.

Correct, they each load their own codec interpretation libraries. >> Obviously, if there is no support in QuickTime for the video format you >> want to play in LO, then you are stuck, because you won't even be able >> to insert the file, let alone play it back if someone else has given you >> a file with an unsupported video codec in it.

I am waiting for a new build to complete that no longer uses that switch to see whether Michael Meeks' comments on my bug issue alter the results of my tests.
