Intel Arc 140v HEVC Hardware Decoding Not Working In Browser

System Info:

  • Laptop: Dell Pro 16 Plus (PB16250)
  • CPU: Intel Core Ultra i7
  • GPU: Intel Arc 140V
  • Driver Version: 32.0.101.6989

Issue:
HEVC hardware decoding works in windows media player after purchasing HEVC extension from the Microsoft store. However, When I attempt to play an embedded HEVC video in chrome it doesn't recognize HEVC when looking at chrome://gpu/. In Microsoft edge HEVC does appear to be recognized in edge://gpu/ and when I go to a HEVC test site the canPlayType, IsTypeSupported, and MediaCapabilities all show that it should it work but the video just becomes a white screen with a shade of grey and black at the bottom of the video and doesn't play. I did have a chat with dell support and they told me it's nothing on the computer itself that should be blocking HEVC from playing in browsers.

Testing Scope:

I have tested on 2 different Dell Pro 16 Plus (PB16250) machines with the same specs and the same results happen on both. I have also tested with an i5 and a 130v and resulted in the same results. In edge://media-internals I did notice error here when attempting to play a video ("cannot select ffmpegvideodecoder for video decoding").

Has anyone else encountered this issue with Intel Arc graphics?
