Jesup profiled YouTube playback on the Moto G5 on YouTube, and observed very bad frame drop:

That's this video: https://www.youtube.com/watch?v=xVKGstMFFFc set to 1080p@60fps

Jesup reports that Twitch's "Just chatting" stream, which should be H.264 @ 1080p/60fps plays smooth, so I think we're using the platform must be running a software decoder for VP9 on this device.

This video is smooth on my SGS6.

iirc the SGS6 has hardware support for vp9 (it was one of the first), but the Moto G5 does not. Can we double check this?

Of course all of them have hardware support for h264.

On my MotoG5 mozilla::AndroidBridge::Bridge()->GetHWDecoderCapability() returns true, and java::HardwareCodecCapabilityUtils::HasHWVP9() return false.

So according to the device itself, it has HW VP8, but not HW VP9.
