you can enable "media.mediasource.vp9.enabled" to make vp9 work which is "default on" on pc where pc has hardware acceleration support
i'm not sure what should i do to get av1 working

my device both supports vp9 and av1 backed by hardware decoding

also enabling vp9 will fix fenix not supporting 4k youtube videos

I'm going to add onto this thread with some more info because it looks like the same issue I'm having.

I have a Moto Edge 2022 with a Mediatek Dimensity CPU and a ARM Mali GPU. https://www.gsmarena.com/motorola_edge_(2022)-11777.php

It looks like "media.mediasource.vp9.enabled" is set to Off by default on the Moto Edge 2022 but not on my Qualcomm Snapdragon phones even though the GPU is supports hardware accelerated VP9 (and supposedly AV1) decode. Is VP9 decode only enabled by default on Qualcomm Android phones?

I'm going to rewrite part of my last comment to something more understandable

"media.mediasource.vp9.enabled" is set to On by default on my Qualcomm Snapdragon phones. Is VP9 decode only enabled by default on Qualcomm Android phones?

Thanks for rephrasing! That's a fair question that I'm going to route to the media team who should be better able to look at this bug and answer your question, or find a more appropriate team.

Looks like VP9 works on Dimensity CPUs starting with Firefox Android 129 from my testing
