X11+EGL context sharing for qmlglsink remains unsupported?

General Discussion
1

Built Qt5.15.18 and tried to use EGL for display of rtsp streaming. But can not see streaming.

2

Nobody knows why X11+EGL context sharing for qmlglsink remains unsupported?

You will have to give a lot more details on your environment to be able to get any kind of semblance of useful help. Things like:

  • GPU (along with the actual GPU driver)
  • OS (Linux/BSD/etc)
  • Distribution (if Linux)
  • Build configuration of both GStreamer and Qt5. e.g. which platforms are built (EGL/GLX/etc) and window systems included (Wayland/X11/etc).

Thanks for your reply.

And what hardware are you using here?

Intel Atom(R) x6416RE 1.7GHz CPU+GPU

And has the system been configured and found development files for EGL+X11 for both GStreamer and Qt5?

What does GST_DEBUG=3,gl*:7,qt*:7 show?
