No, Exynos has the same block limit as the snapdragon chips -- 4k60. The difference is that Exynos doesn't have the same 4096 maximum dimension limit, so it can do 5120x2560 (monoscopic) at 30 fps, while snapdragon can only decode 4096x2560 at 30 fps. The view dependent player is about playing 5120x5120 (stereo) at 60 fps.

It can play a HEVC file that is 6144x3072 at 60fps.

I just tried, and while it does decode a 6kx3k 60 fps video, which is very admirable, it doesn't hold 60 fps while doing it. There are probably encoding options to minimize work on the decoder that could let you push it a bit more. MediaExtractor seems to be arbitrarily limited to a lower resolution, but that can be bypassed.

Can you try with skybox vr? At least on my note 8 Oculus video really doesn't like h265 video that's more than 4k.

I agree with you.

VLC on the Note 8 (and the S8) can do 8K decoding at 48fps, as is demoed here: https://vimeo.com/254723180

We've spent quite a bit of time to get that right, though, and those are rare devices (and does not work with the Qcom version).

Maybe that's one video, with low bitrate (5Mbps), but it worked.
