Re: Qtwebkit and gstreamer on imx6 (yocto Sumo, QT5, framebuffer)

Gustav Evertsson <me@...>

Sorry for the extra mail. I noticed that the formating of my last mail got messed up. I have tried to fix it and and now sending the same question again. Hope it is easier to read this time.

I am trying to play video in  qtwebkit using gstreamer 1.0. I can see that gstreamer get called,  plugins is loaded, src and sink is setup etc but then it just stops and no video is showed in the browser. I use the qt5 example browser to test it. I build Sumo yocto without wayland and x11. Is there anything specific that needs to be done to enable this combination? Video plays  as it should with gst-play-1.0.

We  use Congatec's Sumo branch, it is meta-freescale Sumo branch (from July 2018) plus some minor changes for GPIO etc so I hope it is ok that I send my question to this mailing list.

 The gstreamer logs (GST_DEBUG=4) ends with these lines. I'm not sure what the timed out at the end  means or how to figure out what element/plugin is causing it. If anyone else has this working and could save the same logs so I can compare that would be very much appreciated.
