Ah ok, if you have waylandsink working too, I think you can try with WebKit now, set these env vars:
export GST_DEBUG=“3,webkit*:6”
export GST_DEBUG_FILE=gst.log
then run the browser and try to play a video and send the gst.log file.

I asked you to test gst-play with glimagesink first so as to discard GStreamer issues. If that works well on your platform, move on to WebKit testing.
The appsink we use in WebKit behaves similarly to glimagesink.

hi brother:
thanks for your suggestions and i do the updating at once.
by the way, the webkit select "appsink" higher precedence than "webkit video sink", in the last mail, you suggest me "glimagesink" too,
but which sinker should be select in webkit framework for my problem ? did any relationsbetween appsink and glimagesink, did the appsink is just a wrapper of glimagesink,
so we can know whether the appsink works right by testing the glimagesink directly?
thanks for your kindly supoort.

gst-gl is part of gst-plugins-base in that version of GStreamer. You’re using a pre-release though, I advise to upgrade to 1.14.

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.

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!
