[MacRuby-devel] MacRuby-devel Digest, Vol 36, Issue 42

Wed Feb 23 18:16:48 PST 2011

Shaun August,

I have previously come across the same suggestion you mentioned: using
QTKit's QTMovie class for playing/looping audio.

After implementing the QTKit approach which you can see here:
https://github.com/razic/virus/blob/master/loop.rb the pause between
each loop iteration was either the same or worse than a basic NSSound
object with loops = true.

Neither the NSSound or the QTMovie are sufficient for seamless
looping. However, the Apple PlayFile example which I built/compiled in
Xcode DOES loop perfectly seamless.

How come I can't access a lot of the methods you see in the PlayFile
example, even after loading the necessary frameworks? (I have
BridgeSupport 2)

I hope I'm simply doing something wrong.

Would really appreciate anyone who can provide any sort of insight
into converting PlayFile to macruby.

PlayFile can be found here:
http://developer.apple.com/library/mac/#samplecode/PlayFile/Introduction/Intro.html

Thanks in advance,
Zak
