Hi all. I was hoping I could possibly get some quick feedback on a
problem I'm having.
I have a cocoa app in which I do the following:
- Load a QTMovie with +movieWithFile
- Ensure it is editable
- Delete two segments with -deleteSegment
- Update the file on disk with -updateMovieFile
Everything works correctly except that the size of the file is never
reduced to reflect the shortened duration. For instance if I load a
200 megabyte 5 minute movie and reduce it to a 3 second clip, even
after updating, the 3 second movie is still 200 megabytes.
I'm assuming I'm overlooking a necessary re-compression step, perhaps?
But I can't find any information on how to go about this. Any
suggestions would be greatly appreciated. Thank you in advance.
