[ILUG] Re Quicktime thread.

[ILUG] Re Quicktime thread.

following the thread, I asked a friend of mine who works in "Le Crunch"

>Why can I not get Quicktime for Linux?
The short answer is "You can: QuickTime has been reverse-engineered a 
couple of times"

Somehow, I think your question is "Why can't I play QuickTime movies 
on Linux?", which is a different teapot of sardines. Basically, a 
QuickTime movie is a container for lots of time-based information 
streams. The coding used for these can be different, depending on 
what it is: for example, MIDI control codes, MPEG video, stock price 
info, etc. These different types of data are dealt with by plug-in 
QuickTime Codecs.
The big problem for Linux is that QT3 and later use a proprietory 
video codec called Sorensen Video. This is great for Apple because 
the video compression is the best around. It's bad for the Linux 
world, because Sorensen charge a licence to use the decompressor. 
Apple pay this fee, and give away QT for free because it gets an 
indirect return in the form of Mac-compatible video CDs, websites, 
etc. But, <company-line>there isn't a big enough Linux desktop market 
to justify a Linux QT player</company-line>.

In short, until someone else licences or reverse-engineers the 
Sorensen Video codec, you will not be able to play QT movies on Linux.
