Tenets of AV1 Encoding

AV1 is a next-generation video codec developed by Alliance of Open Media to facilitate VOD, storage and live-streaming. It's usually paired with Opus audio codec, stored in MP4 (ISOBMFF) or streamed using HLS (HTTP Live Streaming). SVT-AV1 is currently the best production quality encoder available (the matter of discusssion here).

Presets

Quoting the SVT-AV1 documentation:

Presets control how many efficiency features are used during the encoding process, and the intensity with which those features are used. Lower presets use more features and produce a more efficient file (smaller file, for a given visual quality). However, lower presets also require more compute time during the encode process. If a file is to be widely distributed, it can be worth it to use very low presets, while high presets allow fast encoding, such as for real-time applications. >

Since we're dealing with simpler AV1 encoding, that does mean we'll be eskewing aomenc-av1, since it requires 2-pass encoding to be able to take advantage of it, and I use it externally since I have access to a special build.

Now, let's get on with the simple guide.

You'll first need to be reasonably competent with command line builds or use a recent up to date ffmpeg GUI with support for SVT-AV1.

As such, I would recommend getting a master git ffmpeg build for the operating system of your choice right here:

Hello. I've decided to share a lot more of my knowledge in public forums from now on, and to not divert any of my focus away from improving the world in a way that stays written in history.

This Gist is about discussing on how to improve AV1 decoding performance on 2 fronts: improving performance through more efficient decoding, and through decoding aware encoding.

Improving decoding performance through more efficient decoding.

Here are many tips on how to improve decoding performance on any machine:

1. Keep your favorite media player up to date!
