Video looks frozen likely because of an issue with your nvidia vp9 decoder. Can you check if this video plays with a standalone GStreamer player? gst-play-1.0 -v https://test-videos.co.uk/vids/bigbuckbunny/webm/vp9/1080/Big_Buck_Bunny_1080_10s_1MB.webm Please also try with the --use-playbin3 option.

Comment on attachment 464257 [details] The verbose ouptus of the commands before and after using --use-playbin3 option. Well, it plays without any problems.

Yes but in this case the selected video sink is not rendering GL textures. Can you try the gst-play commands with --videosink glimagesink ?

Gstreamer version : 1.20.5. GPU hardware: NVIDIA GTX 1660. Driver version: 525.60.11. I was using the flatpak version of Epiphany so I don't know which Gstreamer plugins were installed as dependencies for the browser

Comment 9 2023-01-01 05:28:42 PST
The logs I need are for the Ephy runtime, not gst-play. GST_DEBUG=... GST_DEBUG_FILE=... epiphany ...

If I include the browser tag, it gives me this output: bash: browser: No such file or directory

Type this: flatpak run --env="GST_DEBUG=3,webkit*:6" --env="GST_DEBUG_FILE=gst.log" --filesystem=home --user org.gnome.Epiphany.Devel

I forgot to mention it. I run an OS based on arch linux.

I don't know which flavor of Ephy you installed. You can check with flatpak list and adapt the command line accordingly.

Partially? What's failing now? I can't help if you don't provide the logs.

Comment 18 2023-01-05 05:10:17 PST
I am not able to get any logs. The command: flatpak run org.gnome.Epiphany --env="GST_DEBUG=3,webkit*:6" --env="GST_DEBUG_FILE=gst.log" --filesystem=home --user org.gnome.Epiphany. The output: Failed to parse arguments: Unknown option --env=GST_DEBUG=3,webkit*:6

You typed the app name twice in that command... why?

Comment 20 2023-01-05 07:24:35 PST
You're passing the --env arguments to Epiphany rather than to flatpak. That won't work. Try: $ flatpak run --env="GST_DEBUG=3,webkit*:6" --env="GST_DEBUG_FILE=gst.log" --filesystem=home --user org.gnome.Epiphany which is what Phil originally suggested, except with org.gnome.Epiphany instead of org.gnome.Epiphany.Devel. That will work if you've installed Epiphany in your user installation. If you've installed it system-wide, then use: $ flatpak run --env="GST_DEBUG=3,webkit*:6" --env="GST_DEBUG_FILE=gst.log" --filesystem=home org.gnome.Epiphany

(In reply to Philippe Normand from comment #19) > You typed the app name twice in that command... why? Because I understood it to be that it would be a user of that application at and this was the case when i tried the command: error: app/org.gnome.Epiphany.Devel/x86_64/master not installed.

The command worked. In which directory will the logs be stored in?
