I'm fairly sure that Moonlight used to default to HEVC even if AV1 was advertised by Wolf. So we've defaulted to advertise AV1 as available even if it was just the SW version (aom). There's been a couple reports on our Discord server that this has changed recently and it's causing issues.

We should either remove SW encoding from the default config file:

github.com/games-on-whales/wolf@1429925610/src/moonlight-server/state/default/config.v6.toml (L520-L539)

or change the logic so that we don't advertise AV1 as available to Moonlight clients when it's not HW accelerated.

No, we aren't doing that..

github.com/games-on-whales/wolf@1429925610/src/moonlight-server/state/configTOML.cpp (L387)

Could it be that it was forcing AV1 because the client platform didn't have HEVC decoding available? See also: github.com/moonlight-stream/moonlight-qt@62816a6b2a

Needs investigating..
