11/01/2022, 12:58 AMHmm appears it was a codec issue. h264 not supported my chrome clients? 😕

11/01/2022, 10:52 AMHey Mark, I think you meant LiveKit instead of ion?
We'll look into this. I think the Chromium version that we are bundling doesn't support H.264.

11/01/2022, 2:10 PM@dry-elephant-14928, does that mean Livekit does some form of translation? SFUs as far as I've known, everyone had to use the same codec

11/01/2022, 2:49 PM@nice-beard-68229 Some clients send h264 and some send vp8. Livekit doesn't transcode, and I don't believe there's any requirement that they're all the same (unless you use enabled_codecs on the room)

11/01/2022, 5:47 PM@nice-beard-68229 just to confirm, this only happens when Egress is deployed on arm64 instances. On amd64, we are using Chrome, which has no problem decoding H.264.

11/01/2022, 7:20 PM@dry-elephant-14928 im on an Intel(R) Xeon(R) CPU E5-2678 v3 @ 2.50GHz for the server, and intel 9900k on client

11/01/2022, 7:25 PM@able-gigabyte-21598 So that was the issue! We were explicitly enabling vp8 on the startup config! after disabling that it all worked as expected. Thank you!

11/01/2022, 7:26 PMI ran some 50 person load tests on calls today. It was interesting toi see the loads not handled well on older laptops/hardware

11/01/2022, 8:42 PMare you talking about Egress specifically? or are you talking about the core server?
a lot of it depends on the client.. and how much data each person is subscribing to
