Android Q introduces support for the open source video codec AV1. This allows media providers to stream high quality video content to Android devices using less bandwidth. In addition, Android Q supports audio encoding using Opus - a codec optimized for speech and music streaming, and HDR10+ for high dynamic range video on devices that support it.

The MediaCodecInfo API introduces an easier way to determine the video rendering capabilities of an Android device. For any given codec, you can obtain a list of supported sizes and frame rates using VideoCodecCapabilities.getSupportedPerformancePoints(). This allows you to pick the best quality video content to render on any given device.

You'd think that Google would have, well, Googled for the successes and failures in this field before surging ahead. Or at least listened to Monty, since he's The Woz of codec design.
PSNR may not be good, but it is easy to calculate.

And Google REALLY likes objective metrics. They trust a number from a computer more than their own eyes.

It's one of those "looking where the light is" kinds of problems.

Geez, no wonder people like Elon Musk are so concerned about certain tech companies going all-in on deep A.I.

Say, does anyone know if the Android Q AV1 decoder has/will have PlayReady integration? If so, what level?

I strongly doubt it. If there is an integration I'd be shocked if it's not software based, which would max out at SL2000.
