Hi brother:


sorry for fogotten the cc thing.
my gst version is  "1.13.90",  from the official webkit ,i only found the "gst-plugins-gl-0.10.3.tar.gz" seems like  "gstreamer_gl" you said , but the version seems did not match with the gstrreamer, and the latest update day is 2012,.
is this the gl package you said?


much appreciate your help.

hi folks :


 My project is  based on yoccto 2.5 project, with the  kernel version is  4.9 and webkit is 2.20.2.


a part of my bb file is as follows, so you can see , the display window show normal only if the opengl and gst_gl must be deleted.

You need to make sure gst-play-1.0 —videosink=glimagesink works on your platform before starting to debug webkit.
After you have validated that works, make sure you enabled gst_gl in that packageconfig thing. Which GStreamer version do you use?

Hi!


Which linux distribution do you use? If you are using the latest Ubuntu (17.04 is the version I think) or Debian then you need to install gstreamer1.0-gl. See also https://bugs.webkit.org/show_bug.cgi?id=184925

hi folks:
    i make a test about video player with video tag based on midori and webkit2.22.2, but seems only when i disable "GSTREAMER_GL", the display window can be displayed normally.
if the GSTREAMER_GL was enabled, the decoder process working fine but the browser cant show the player window, just a blank window.
so,from the code, it seems the difference between the two test is the display sinker of gstreamer pipe was different.
1.if GSTRREAMER_GL enabled, it would be use the display sinker "createVideoSinkGL" returned
2.if GSTRREAMER_GL disabled, the default display sinker would be webkit video sink.


seems only method 2 can use, but i found another problem when using the way 2(webkit videw sinker), that is  when playing high quality streamer with browser, the cpu occupancy rate was very high (about 50 percent) of process 'webkitwebprocess'. 


so i dont know how to choice, which is the better way to deal with this problem, much appreciate your help!
