Hardware decoding and AV1 support both disabled on Steam Deck, despite the hardware supporting both in Remote Play

Terminal doesn't have any useful data sadly.

Interface lists Hardware Decoding as disabled and the option is greyed out, while AV1 is listed as Not Available.

Any chance of a fix? Steam Link works WAY better than Remote Play, so having proper AV1 support would really help.

Edit: the title should have AV1, not AV!. Apologies.
