Hello,

I am not able to adjust the tempo of a video file while it is playing.
When i adjust the tempo the video stops for a moment and starts again.

What is the reason ?
Can you suggest how to do it smoothly.

Thanks and Regards,

Ravindra.

Hello,

this is unfortunately due to the way the change of playback rate is implemented by DirectShow itself: each time the playback rate is modified, through a specific function of the DirectShow IMediaSeeking interface (Microsoft's code on which we don't have control), the filters graph will stop for some millisecond and will restart immediately, disallowing a smooth transition.

Kind Regards
