Running gmlglsink without x11

[Dmitry Lavnikevich]

Hi all,

I am trying to get qmlglsink working on the x86 platform. Built the
qmlsink example from the gst-plugins-bad for a start. It successfully
runs under the X. But when I try to run it from console with:

$ ./play -platform eglfs

The playback doesn't start. With GST_DEBUG=5 I see:

...

I see the same behaviour both from my archlinux platform and my target
Yocto.

Would be incredebly greatful for any pointers where to look at.

Best regards,

Dmitry,

I would like to use qmlglsink on an iMX6 platform with OpenGL ES instead of X11.  Did you figure out if qmlglsink requires X11 to work ?

It doesn't, it works on imx6 with the Qt EGLFS backend.

Hi Sebastian,

Thanks for the information.  That is good news - sounds like it should work on my setup.  I can't see qmlglsink in the output of gst-inspect-1.0 at the moment but hopefully I just need to tell buildroot to include it.

Hi Sebastian,

I'm having some trouble persuading buildroot to actually build the qmlglsink stuff.  The first issue I had was that the gst1-plugins-bad-1.10.4/configure script in was being run with --disable-qt.  I added a buildroot config option to allow me to toggle that on and that got me a bit further.  The configure script is now run with --enable-qt but fails further on:

It seems to be expecting a Windowing configuration variable.  I'm not using X11 or Wayland so I'm not sure how this should be set.  Any ideas ?

EGLFS is a "Windowing integration". Please try with GStreamer 1.12 or
newer, there were relevant changes for that, and imx6 in general.

Configure basically has to go into this specific case here:

Okay, I have now managed to build the gst1-plugins-bad-1.12.1 package with the qt plugin.  On my target system the output of gst-inspect-1.0 shows the qmlglsink object.  So next I tried to run the qml-example program from the gst1-plugins-bad/tests/examples/qt/ directory.  That builds fine but fails at runtime because the glupload element was unable to be created.  The videotestsrc and qmlglsink objects were created okay.

I have the glupload element present in the output of gst-inspect-1.0 on my desktop system but not on my target system.  Is glupload also built as part of the gst-plugins-bad package ?  Does it need opengl rather than egl or gles2 ?  The config.log file shows these options were given to the configure script:
