However, our own tests with VP9 encoded video on a Samsung Galaxy S7 do not in any way match the recommendations listed on this page. We have multiple European S7 phones (Exynos SOC), and we are not able to play a 3840x2160 VP9 video at 25fps, let alone the 60fps the Oculus documentation suggests is possible. Regardless of which video player we use. We are able to play a 4096x2048 VP9 video at 30fps, but 60fps is also not possible for that power-of-two resolution.
I was wondering why the documentation could be so wrong about the capabilities of the S7, and what the suggested resolution (and framerate) is of very high quality video on Gear VR. We thought using 3840x2160 VP9 at 30fps would be a good solution, and S6 phones support this resolution just fine. It is just the S7 that is somehow not capable of this. Could it be a software issue that Samsung could resolve with an update, or is the S7 actually less capable of decoding high resolution VP9 video than the S6?
