Question Is A52s not capable of vp9 4K60 playback?

[komodala]

It seems that although the 2160p shows up in the selection, I can't play 4K60 YouTube videos properly, let along 4K60 HDR ones. I've tried with browser, Youtube app, Vanced, NewPipe, all without luck. Even when I downloaded webm files, A52s still struggles to play.

Interestingly enough, A52s actually can play 4K60 HDR10 HEVC video demos perfectly that I downloaded.

So is this about vp9 codec?

There was a thread about a similar or the same issue once:

https://xdaforums.com/t/no-4k60-playback-on-a52s-sd778g.4408675/

So maybe xplayer might help you? Although I think since that thread was about existing files that user had, it was probably H.264 files?

(I was not involved in that thread, although I remember I did download that test-file that was there and has since been removed, and I indeed could not play that one without stuttering)

Yes, Google showed me that thread before I posted.

I did test samples from 4kmedia.org, and A52s actually can play 10bit h.265 files with high bitrate using built-in player and/or xplayer without problem, albeit the highest bitrate it can handle is around 50-60 Mb/s I think.

So my real problem is about vp9.
