<![CDATA[Different behaviour of QT6 when changing camera resolution on Windows/Linux]]>Hi,
Im able to change camera resolution dynamically on QT6 but the behavior is different on WIndows and Linux, below is the detail

Windows

  • After instantiating QCamera with some default resolution

  • Calling setCameraFormat to set for new resolution

  • I will need to call Camera stop and start in order for it to take effect.

Linux (On Unbuntu 20.04)

  • After instantiating QCamera with some default resolution

  • All i need is calling setCameraFormat to set for new resolution and it will take effect.

What is the proper/unified workflow when you want to change camera resolution dynamically (eg, after QCamera is already instantiated)? thanks

I would suggest to check the bug report system to see if it's something known and if not, please open an issue about it.

Which version of Qt 6 would that be ?

Since 6.5, the default has changed to the new ffmpeg backend. Before that, it was the native backend which could have different behavior on some details.
