Apple's recently released Technical Q&A 1518 uses UTIs to identify
Image files. Given a path to a file, the routine show returns true if
the file is an Image file. It actually uses the
CGImageSourceCopyTypeIdentifiers: call to find a list of UTIs for the
images files Quartz supports.
What about videos?
I need to be able to do exactly the same thing for the various file
formats that Quicktime supports. (ex .mov & .mpg file types). I can
not find a similar call in Quicktime to provide the UTIs for
Quicktime compatible files.
Does anyone have better suggestion? I do not want to have to try to
open the file, to determine if it is a video.
Thank you
Steve
