H264 1080p 60fps supported?

[luyi1888]

I tried it on Orange Pi PC(H3). It cannot play H264 1080p 60fps video smoothly. (Audio/Video out of sync)
30fps video is fine.
According to H3 Datasheet, It should support H.264:1080p@60fps.
Is it normal?

We are likely hitting a software performance limitation here, the hardware should be able to decode this.
libvdpau-sunxi isn't really optimized for maximum performance yet, some dumb things like clearing the whole window each frame with XClearWindow could really hurt at 60fps.
