Here’s the Description
Codecs like H.264 and AV1 are the key enabling technologies for all entertainment and business-oriented video distribution, whether movies distributed via Netflix or videoconferencing from Zoom and similar services.
At a high level, codecs come from two different sources; standards bodies like MPEG (MPEG-1, MPEG-2, H.264, HEVC, VVC, EVC, LCEVC) and from so-called open-source development (VP9, AV1). What does this mean regarding royalties and usage costs? And with so many codecs available, when will each become relevant for deployment, if ever?
Here are the contents with the time code.

The webinar was designed for newbies who want to learn about codecs and experienced streaming professionals who want an update on codecs for 2021 and beyond. You’ll walk away knowing which codecs are likely to stay or become relevant to your business, what they will cost to deploy, and how to evaluate their utility.
