VideoSink::videoFrameChanged sends no signal under Windows 11

Zbigniew-Sch

Hi,

"QVideoSink::videoFrameChanged" sends no signal under Windows 11, under Windows 10 everything worked without problems.
Has anyone already tried this or is this BUG. I use Microsoft Visual Studio 2022 and Qt 6.7 (C++)

Hi,

Please provide a minimal compilable example so that people can try to reproduce this behavior.

If possible, a video file that triggers this.

Hi,

Sorry that was my mistake, now it works properly. But I have another question that you can help with. After updating the OS from Windows 10 to Windows 11, I have problems with QMdiSubWindow. All windows have the white title bar and the active QMdiSubWindow is not marked in blue

What was the issue ?
As for your second question, try forcing the style to windowsvista.

Zbigniew-Sch

Correct is : mediaPlayerObject->setSource(QUrl::fromLocalFile("local file path")) and not
mediaPlayObject->setSource("File path")
How can I do that (windowsvista style) ?

SGaist

As shown in the QStyle documentation.
