Nils, do we have anyone specific to investigate ARM64 issues?

Comment 2

[Nils Ohlmeier [:drno]]

No we don't. Since you and me are the ones with ARM machines it would have to be investigated by one of us :-)

Comment 3

[Alex Chronopoulos [:achronop]]

If you have a ARM64 machine can you try to confirm or not this issue?

[Bryce Seager van Dyk [:bryce] (he/him) - Not reading bugmail]

Confirmed. :ajones and :cpearce are also aware of this. I'm uncertain if they've investigated further than I.

When I clicked to view video stats on Twitch it shows:

Video Resolution:0x0
Display Resolution:916x515
Skipped Frames:0
Buffer Size:0.00 sec.
Latency To Broadcaster:0.00 sec.
Latency Mode:Normal Latency
Playback Rate:0 Kbps
Memory Usage:64 MB
Backend Version:2.8.4-ca0f9c24

It appears we're not getting the content to playback?

It plays when you set javascript.options.wasm=false so I'm going to mark it depending on bug 1521939.
