I have a question regarding the QTTrack methods FindFirstSample,
FindNextSample, FindFirstKeyFrame, FindNextKeyFrame.
It is unclear in the Language Ref, what these methods actually do. I
have successfully created a QTTrack (from an EditableMovie) and been
able to reference its properties. (ie MediaType, Enabled, Duration,
etc...) However, when I call the above mentioned methods, nothing
seems to happen. I'm assuming that if there was some sort of data
returned here that I would get a compiler error message telling me that
I need to use the value returned by this function, but I don't get any
such errors. Here's my code.
dim VidTrack as new QTtrack
VidTrack=Window1.MoviePlayer1.MyMovie.VideoTrack(1) // MyMovie is a
an EditableMovie property
// MsgBox VidTrack.MediaType // This worked fine...returned "vide"
VidTrack.FindFirstSample
Window1.refresh
I guess what I'm expecting to happen here is for MoviePlayer1 to locate
to the "First Sample", but of course, it's not.
Any insight would be greatly appreciated.
