When I load an animated gif file into osgmovie demo, the movie plays fine.
However, the '+' key slows the movie down, and the '-' key speeds the movie up.
Why are the keys backwards? I am using osg 2.8.3 on windows.
Also, in the demo, why is the pointer returned by the osgDB::readImageFile
casted to an ImageStream as opposed to an ImageSequence (it failes to cast to
an ImageSequence)? I guess I'm not sure what the difference between the two
are. The implementation for the speed up and down are missing in the
ImageStream class:
Code:
virtual void setTimeMultiplier(double) {}
virtual double getTimeMultiplier() const { return 0.0; }
but the implementation is present in the ImageSequence class:
Code:
virtual void setTimeMultiplier(double tm) { _timeMultiplier = tm; }
virtual double getTimeMultiplier() const { return _timeMultiplier; }
ImageSequence is the only class I see that inherits from ImageStream.
Thanks,
Brian
