[content] + \section1 Screen Capture Limitations + On Qt 6.5.2 and above, the following limitations apply to using \1ScreenCapture: + \list + \li It is only supported with the FFmpeg backend. + \li It is unsupported on Linux with Wayland compositor, due to Wayland + protocol restrictions and limitations. + \li It is not supported on mobile operating systems, except on Android. + There, you might run into performance issues as the class is currently + implemented via QScreen::grabWindow, which is not optimal for the use case. + \li On embedded with EGLFS, it has limited functionality. For Qt Quick + applications, the class is currently implemented via + QQuickWindow::grabWindow, which can cause performance issues. + \li In most cases, we set a screen capture frame rate that equals the screen + refresh rate, except on Windows, where the rate might be flexible. + Such a frame rate (75/120 FPS) might cause performance issues on weak + CPUs if the captured screen is of 4K resolution. On EGLFS, the capture + frame rate is currently locked to 30 FPS. + \endlist + //! [content] +*/ |
