  "message": "Exercise AV1 simulcast paths in tests.\n\nThis is something we get \"for free\" with the\n\"WebRTC-AllowDisablingLegacyScalability\" field trial that has been\nwired up to support VP9 simulcast.\n\nThis test works and passes, however the ramp-up time is pretty bad.\n- VP9 simulcast takes approximately 4 seconds to ramp up.\n- VP9 SVC takes approximately 16 seconds to ramp up.\n- AV1 simulcast takes approximately 22 seconds to ramp up.\n\nA TODO is added (webrtc:15006) and the test is given extra timeout,\na full minute to get bytes flowing on all layers.\n\nDespite ramp-up being bad, it\u0027s important to test that AV1 simulcast\nis in fact working to avoid regressions due to obsolete assumptions\nabout which codec do or do not support simulcast. AV1 simulcast is an\nopt-in feature so there is no harm in the API not being perfect yet.\n\nBug: webrtc:15005, webrtc:15006\nChange-Id: If0158d172647f0462bd6db802406249d93e01871\nReviewed-on: https://webrtc-review.googlesource.com/c/src/+/297982\nReviewed-by: Ilya Nikolaevskiy \u003cilnik@webrtc.org\u003e\nCommit-Queue: Henrik Boström \u003chbos@webrtc.org\u003e\nReviewed-by: Erik Språng \u003csprang@webrtc.org\u003e\nCr-Commit-Position: refs/heads/main@{#39586}\n",
