Screensharing crashes a call on Chrome 124

[Dziango]

Steps to reproduce

1. Audio call another person
2. Attempt to share your screen
3. Call immediately crashes

Outcome

What did you expect?

Screensharing working as usual.

What happened instead?

The call crashed. It seems that the problem applies exclusively to Chrome version 124.0.6367.60. The previous version, 123.0.6312.122, works just fine, as does Firefox.

At first, I noticed such behavior on our own server. However, I checked, and the same problem applies for app.element.io.

From what I can gather, there seems to be a problem with the AV1 codec:

`DEBUG: Call 1713532391264S7TWnfigHdEhMFKK gotLocalOffer() failed to create offer: {\"stack\":\"Error: Failed to execute 'setCodecPreferences' on 'RTCRtpTransceiver': Invalid codec preferences: invalid codec with name \\\"AV1\\\".\\n at R.getRidOfRTXCodecs (https://[redacted]/bundles/79a6ead0638f088928c8/bundle.js:2:765354)\\n at R.gotLocalOffer (https://[redacted]//bundles/79a6ead0638f088928c8/bundle.js:2:763018)\\n at R.wrappedGotLocalOffer (https://[redacted]//bundles/79a6ead0638f088928c8/bundle.js:2:762673)\\n at https://[redacted]//bundles/79a6ead0638f088928c8/bundle.js:2:762530\"}",`

This looks like an upstream issue https://issues.chromium.org/issues/331565934
