And that code works for me:
dim file as FolderItem = SpecialFolder.Desktop.Child("test.m4v")
dim m as movie = file.OpenAsMovie
dim f as new QTFrameExtractorMBS(m)
dim posit as Double = 0
do
f.Position = posit // set new position
f.Idle // update currentpicture
dim p as Picture = f.CurrentPicture
file = SpecialFolder.Desktop.Child(str(posit)+".jpg")
p.Save(file, p.SaveAsJPEG)
posit = posit+1 // next second
Loop Until posit>29
I write pictures to disk. I expect your problem is more that window does not
update. Maybe you add something like window.UpdateNow.
