QScreenCapture with partial screen

[Timmy]

Hello,

I'm trying to record screen by new API QScreenCapture in QT 6.5.3, but it only captures the whole screen. Is there any way to capture partial screen? Like setGeometry, I checked the documents for QScreenCapture, QMediaCaptureSession and QMediaRecorder, no such function.

Hi and welcome to devnet,

AFAIK, currently no. Are you trying to record something specific ?

[JoeCFD]

@Timmy you can use gstreamer or FFmpeg to do it.

[Timmy]

@SGaist Yes, most screen recorder software have this function, I'm just trying.

@JoeCFD Thanks, I already tried FFmpeg before. It works. As I know QMultiMedia backend also is FFMpeg, So I'm trying to use QMultiMedia instead of calling FFmpeg directly.

[SGaist]

@Timmy not all features of ffmpeg are supported but you might be able to implement that one in Qt yourself.

@Timmy you may rely more on FFMpeg than on QMultiMedia. QMultiMedia is a very basic tool for now. I do not use it at all.
