MP3 without QuickTime on Windows

[Lynch, Jonathan]

This is perhaps an ignorant question - but I never hesitate to embarrass
myself publicly...

If a multimedia developer was going to create a Rev based app, with
video, audio, etc... Is it truly necessary to depend on the user having
QT or WMP installed?  Would it be possible to store the entire QT
application as a compressed custom property in a stack. When the program
runs, it could look to see if QT is in the same folder as the program -
if it isn't, then it could uncompress QT, write it to an executable
file, and then use it as needed.

Would that work?

You need to have *some* kind of multimedia support on the system, which
is
usually Windows Media Player if not QuickTime.  The only other way you
might
do it is to hand off playback to some other app that is capable of
playing
MP3s.  But you may wind up with little to no control over playback and
if
WMP is not on the system you may not have success at all.

The simple way to test if MP3s will work on the system is to double
click an
MP3 file and see if it plays.  If it does, determine what app is playing
it
and see if you can use the launch/open process or shell commands to
handle
launching of the file in the app (again, you may not be able to have any
control over playback if you go this route).

As you discovered, Rev is natively capable of playing WAVs, AU and AIFF
files, but not MP3s.

In my experience, if you want to use a player in Rev, you really need to
have QT or WMP installed, but perhaps someone else knows differently.
