Shouldn't GetRate() return a float?

Tristan

Hi.

I'm using a QuickTime movie.
This code:

document.movie.SetRate(0.5);
alert( document.movie.GetRate() );

will correctly set the movie rate to 0.5, but GetRate() will return 0,
not 0.5 .

How can I solve this problem?
I have tried to parseFloat() the value returned from GetRate(), but it
hasn't worked.

Thanks.

Hi,

Yes, according to the API setRate expects a float, so you are not making a
mistake.

But getRate() returns 0 if:
1) The movie is finished.
2) The movie is paused (via userinteraction eg)

Could any of them apply to your situation when you call getRate()?

Oh, here is the rather long URL for the API and also the notes on when it
returns 0.

Yes, and the movie correctly will slow down.

No, I execute that code while the movie is playing, and if it'd be
paused, SetRate(0.5) should start it. :-(

Here it is (it's the reference I'm using):
<http://snipurl.com/v9np>

The problem is that GetRate() seems to return an integer:

m = '';
mov.SetRate(0.98); m += mov.GetRate() + ' ';
mov.SetRate(-0.44); m += mov.GetRate() + ' ';
mov.SetRate(3.75); m += mov.GetRate() + ' ';
mov.SetRate(-3.5); m += mov.GetRate() + ' ';
alert(m);

will return me this alert msg: '0 0 3 -3 '.

The movie will correctly run at the rates specified, but GetRate() won't
give the correct (float) values.

I've tried the code on Firefox 1.5, Opera 9 and IE7beta2.
Whit the QT plugin v7.0.4.

I can't find any solution with google. :/
I'll try to contact the Apple Team.

Thanks,
