This article is about a video lesson that computes the bandwidths savings afforded by the FFmpeg-based implementations of VP9 (libvpx-VP9), H.264 (x264), HEVC (x265), and AV1 (libaom-AV1).

Towards the end, it …

I recently received the following message from a colleague, a respected IP attorney, on LinkedIn. Hi Jan, hope all’s well. What do you make of Google joining HEVC Advance’s pool (now Access Advance)? Talking to some relevant players, I think it’s a prelude to Chrome supporting HEVC. Do you think it has any implications for AV2 or VVC? Thanks, and …

A new Streaming Learning Center Course, Encoding with the AV1 Codec, teaches how to optimize AV1 encoding with four AV1 codecs (aomenc, libaom-av1, SVT-AV1, Aurora1). Available now for $99.95. If you’re looking for a structured AV1 training program to learn how to encode with AV1, this is it. Click here for more information or to purchase the course.  The AV1 …
