Such as:
Qt5 implementation of GUI interface is to use the open gl, system for ubuntu16.04, graphical interface system using xorg, framebuffer board is only one that I use/dev/fb0
Question:
Video and qt5 layered interface display?
Xorg has a similar interface?

Effect is qt5 osd will be a video, can see video through the interface

CodePudding user response:

Actually I want to use qt implementation is similar to the effect of osd, qt transparent interface, can see video of qt below;
That is to say, video display and qt interface each other, this is involved to make the two layered display:
Qt on the top floor, video in the next layer, such as if there are two framebuffer:/dev/fb0/dev/fb1
Qt on fb1, video on fb0

But I'm on the board at present only a/dev/fb0,
So wanted to see if you have any other ideas

So only after considering the qt interface and video layered, by the hardware to combine the...

If the audio and video encoding is such can play normally:
