QML Camera type is so heavy

  • Hi,

    After profiling my application by "QML Profiler" It seems that Camera type is so heavy that influence on application startup time I use loader and asynchronous but there is merely difference achieved at the end.
    Do you have any suggestion for me?

    Are you on Linux? In my experience QML Camera is especially slow on Linux. There were some fixes for it back in Qt 5.12.1 I think. So make sure you are using the newest Qt and up-to-date system.

    One solution I have found, but which is a bit ugly - use QCamera from QtWidgets. It works way faster.

  • @sierdzio yes I use Linux ,thanks for your reply but is there a better way to speed up Camera?
