Hi developers,
I use Qt 5.6.0 on Windowd (with DS plugin).
I faced with the problem that the example:
qtmultimedia\examples\multimediawidgets\customvideosurface\customvideowidget\
is very-very-very slow.
For example if I play any video file, then my CPU loading is 40%, and I
see that the video
is displayed jerkily, and if I want to drag the window by the mouse,
then it happens also jerkily.
I suspect that it happens due to there are not used the OpenGL rendering
(yes?)...
Because if I use the QVideoWidget, I see that my CPU load is 0%, and all
fine.
Or, maybe the internal QtMultimedia's implementation has a bug when is
used the custom
QAbstractVideoSurface (instead of QVideoWidget) to show the video content...
So, my question is: is there are any tricks or examples how to implement
the high-perfomanced
video application with the QAbstractVideoSurface ?
BR,
Denis
