Issue Summary : I have laptop with an integrated AMD Vega 7 GPU and a RTX 3050 Mobile, when watching videos on Youtube or Twitch, I see that epiphany uses the dedicated Nvidia GPU for decoding the video, but the application itself is launched with the integrated graphics. My integrated gpu supports decoding avc and vp9 but not av1. This is causing huge battery drain issues for as is expected. I have also tried launching using dedicated graphics card but I'm not able to play videos at all If I do that. This might be a separate issue because nvidia. Steps to reproduce : 1. Open Gnome Web on multi GPU setup (ideally similar to mine) 2. Open any webpage that has video playback (e.g. Youtube, Twitch etc) 3. Play the video and check nvidia-smi or any other monitoring tool to see what GPU is used for decoding What is actually happening : It uses the dedicated nvidia graphics to perform the decoding instead of the integrated GPU which the application is launched with. What is expected to happen : It should use the integrated graphics or the CPU to perform decoding, unless the app is specifically launched with discrete graphics.

Please share the webkit://gpu infos. We'd need a WebKit developer with a similar setup to investigate, I don't use nvidia, sorry :)

Hi, any update on this issue?
(In reply to Aniket from comment #4) > Hi, any update on this issue? Please don't post this kind of comments (or +1 comments). There will be an update whenever someone finds the time to work on this.
Hi, It's been a while since I reported this issue. I have tested this scenario (i.e. watch a video on Youtube) and it seems that epiphany is now using the correct GPU for decoding, I don't know exactly which version this was fixed in. The version I tested on is : WebKitGTK 2.44.3 GStreamer 1.24.7
