QTW 11 - SetTrackLoadSettings (1-May-95)
Q How does SetTrackLoadSettings work in QuickTime for Windows 2.0
A QuickTime 2.0 introduced the really neat feature of setting preload flags into
the movie itself so that selections of tracks, or tracks could be preloaded
without the need to worry if LoadTrackInfoRAM is implemented in the playback
application or not. You could read more about this on page 8 of the QuickTime
2.0 for Macintosh document, which is part of the QuickTime 2.0 SDK kit
available from APDA .
However, something that was not clearly stated is what QuickTime for Windows
thinks about these pre-load flags. QuickTime for Windows 2.0.1 honors these
flags for text and MIDI tracks, not sound or video. This will change in the
future.
