How to play -ve resolutions using Qcamera
-
My video device has a resolution of ( 1920 x -1080p ).
How do I play it from QT camera Application (QCamera class)?Qt Camera Application actually plays it but the preview is not available.
How do I preview in QT for a resolution of ( 1920 x -1080p ) using camera example.If this can't be done by camera example, what else would be the ideal way?

Hi,
What video device are you talking about ?
On what OS ?
Which version of Qt ?
Do you get any message on the console when running the camera example ? -
@SGaist
Thanks for the reply!My device is the Media driver (Directshow) where I am simulating data.
OS : Windows 10
QT Version : 5.9.2I get the following messages for the both the resolutions (1920 x 1080) and (1920 x -1080)
"Failed to get the video control"
"Failed to find the video proc amp"But, when the resolution is (1920 x 1080) my data is streaming and also a preview is available in the QT camera example.
when the resolution is (1920 x -1080) my data is streaming but there is no preview available in the QT camera example.
When I select the device in the camera example it starts playing but there is no preview of the data.I hope you get my problem statement.

I didn't realise:
-1080p? What that's minus sign doing there ?
