Re: kQTAudioPropertyID_RateChangesPreservePitch on Windows


OK, I solved the problem described below by installing the latest QuickTime for Windows SDK (7.1.0).

But using the QTSetMovieProperty / kQTAudioPropertyID_RenderQuality doesn't seems to have any effect on Windows?
Whatever quality values used, it's still only the default very low quality.

Isn't the higher quality settings that are available on Mac available on Windows?

Thanks for a clarification,
Rolf



Hi,

I'm playing a movie file with kQTAudioPropertyID_RateChangesPreservePitch
On Mac I can set the quality with

UInt32 quality = kRenderQuality_Max;


OSErr err = QTSetMovieProperty(theMovie,

kQTPropertyClass_Audio,

kQTAudioPropertyID_RenderQuality,

sizeof(quality),

&quality);



On Windows kQTAudioPropertyID_RenderQuality (and kRenderQuality_Max etc)
doesn't exist (it seems?)

Is there another way to change the quality on Windows?

The default quality is quite bad.



Also, on Windows it seems one need to call MoviesTask() periodically for the
file play.

On Mac this is not needed. Should this be needed on Windows or is there
another way?
