I've been following the thread about what tool (Qt Quick, widgets, Qt3D,
QOpenGL) best utilizes the GPU. I have a slightly different question and
would really appreciate some advice. We have a requirement to display
multiple video streams with overlays. We've come from a background where
we started with Qt2 and have gradually migrated up the versions, to now
finally be on Qt 5.6. We are at point where the mechanism to display the
video display is being re-evaluated.
Ideally the GPU should handle the scaling and colour conversion of the
YUV image data and we should be able to use QPainter for drawing the
overlays. It needs to work both on Linux and Windows. What would the
recommended tool be to achieve this: Widgets, Qt3D, QOpenGL, Qt Quick?
