QVideoFrame::Format_Y16

[ABest2]

I have a QAbstractVideoSurface which displays a QVideoFrame. This works as expected for QVideoFrame::Format_RGB32 and QVideoFrame::Format_ARGB32. I am copying (memcpy) the data directly to the data section of the QVideoFrame. The data I am trying to display is 16 bit grayscale so I would prefer to use QVideoFrame::Format_Y16. But, the display area is white (no image) with this format chosen and 16 bit data copied to the QVideoFrame. Are there limitations on the use of QAbstractVideoSurface for QVideoFrame::Format_Y16?

Also, I do not know if the difference between presenting the grayscale values in Format_RGB32 will be visibly different than Format_Y16 on a normal computer display where this application will run. Should I stick to RGB32?

I am fairly new to Qt.

Thank you,
Aaron

Hi and welcome to devnet,

I am not sure that this format is currently supported in the shaders implemented for QtQuick. That is something you'll have to check.

I do not know where I would look for this information. Any additional details would be appreciated.

Thanks,

The QtMultimedia sources is the starting point.
