Since Snow Leopard, QTKit is now returning color corrected image data from functions like QTMovies frameImageAtTime:withAttributes:error:. Given an uncompressed AVI file, the same image data is displayed with larger pixel values in Snow Leopard vs. Leopard. Currently I'm using frameImageAtTime to get an NSImage, then ask for the tiffR...

I'm using the standard CoreVideo Display Link + QTVisualContext to render a QuickTime movie into an NSOpenGLView subclass. I would now like to synchronize a timeline view with movie playback.

Hi all we are looking for a cross platform video framework to add to our application, that would allow us to read video files in various formats, get their frames and play them. One suggestion was VLC/VideoLan, but its a GPL framework and therefore we can't use it We thought of Apple's QuickTime, but it can't read WMV files (and needs...

Looking at Apple Website they do an outstanding job with the quicktime movies they show off to their users. When I've included quicktime links before, the player that actually shows to users is quite bland, and across browsers really differs from what it looks like in safari, chrome, ie, firefox. Apple seems to handle all these conditi...
