Connect the videoFrameChanged signal of the sink to a custom slot so you will have the frame available to be saved.

@JoeCFD said in mouseMoveEvent not being called:

do you have the following line in the constructor of class MouseTrackingFrame?
installEventFilter( this );

No, the install_filter(...) function being called from MouseTrackingFrame::postSetup() does that. But I'm not sure if it has any effect - I saw a post somewhere which said Qt ignores when the widget itself is passed to installEventFilter(...)

Hi
Well you override the mouse functions and make it happen.

virtual void mousePressEvent( QMouseEvent *e ); virtual void mouseMoveEvent( QMouseEvent *e ); virtual void mouseReleaseEvent( QMouseEvent *e );

have a look here

@sayan275
i think you have to use another QMediaPlayer instance designated for the preview frames.

There is an example application showing this (taken from here).

@Wieland Well i found my problem, I chose the wrong baudrate. Now i have to adjust my code, but i think it will work sooner or later. Thanks again!

Please let me know if there is any update on this.
