If you thought MPEG was just a file format, you would be wrong. As it turns out, MPEG is short for Moving Picture Experts Group, and it means that there is big business behind the use of these MPEG files.
There are now some nonprofit groups coming along to offer an alternative to the big name video codec giants of the industry. Alliance for Open Media (AOMedia) is one that creates the open, royalty-free video coding format called AOMedia Video 1 (AV1).
AOMedia has grown large enough now not just because of its brilliance but also because it was founded by some of the biggest names in the industry, including Amazon and Google itself.
