HN discussionOne of the alternatives is clearly not objectively so much better for everyone. If they were so much better then VP9 and AV1 wouldn't exist.

HN discussionFYI we're actively working on native Linux support. It will be rolled out in phases, but we're targeting parity with the Mac and Windows platforms. The first release is planned for this April. The client is in early field trials right now. I don't think we have public links to the client as yet.

HN discussionVVC is great, but AV1 is fast enough for realtime use, while VVC is not. Cisco has had it working for some time. Basically, AV1 to me seems like it's basically a zero tradeoff solution vs older codecs, so is a good "new standard" to base around then think about what is next from here. https://blog.webex.com/video-conferencing/cisco-leap-frogs-h...

on “Intel becomes the first to offer full AV1 support with its new Arc GPUs”I hold the wider Cisco org with as much contempt as any non-MBA technologist, but to be fair, the WebEx team appear to be doing some interesting things with zero trust [0], MLS [1], and watermarking [2]. A lot of mass market / SaaS comms tools are abysmal at best on the security front but it's nice to at least see some semblance of effort on a few layers of controls.
