[Question] How to get screencaps? #569

Closed hutterm closed 3 years ago

hutterm commented 3 years ago

Is there a way to get screencaps from a video with this library?

I want to implement some kind of preview onto a time slider when hovering with the mouse. Is there a convenient way to use this library for that or do I have to resort to external ways?

the ability to obtain a keyframe image for a specified timecode/position would be useful to me as well.

the way I solved it for now is to open the file in a secondary MediaElement as well and then use Seek and CaptureBitmapAsync but this feels quite hackish

the CaptureBitmapAsync method works. If you'd need a more precise and complex alternative, subscribe to the RenderingVideo event of the control.
