How to use hardware codec on Hikey970?

Hello,
Is there anyone trying h264 decoder on hikey970?
Vdec driver is successfully probed and i don’t know how to use it.
Is there any codec SDK or MPP library for download?
Thanks!

Hello, I’m also looking for this information. Have you found it later? I’m looking forward to your reply

As far as I know there is no public userspace library.
Kernel api looks like openmax api but userspace part is missing
