doing exactly there, where you mentioned.

strange that volume does not work, but this helps https://github.com/valbok/QtAVPlayer/pull/430

btw doing 1. Preview and set the volume 2. Start sliding, -> always max volume is used, it sets volume to 1.0, is it correct?

> 2/3s delay before to take effect Right, looks bug, volume is changed only when new frame is arrived which is not nice. Thanks, will fix
