nope
the question is to the graphics drivers
check the clinfo output - if it doesn't work then SVP won't work too

and I'm not even sure AMDGPU-PRO supports OpenCL on 7xxx series

so, it's not that I installed the driver wrong, but the driver itself is not supported for opencl?
is this what you mean?

I installed svp 4 linux like the instruction in the website. When I start the video, I got a message "Error initializing OpenCL Subsystem. Please re-install graphics driver."
The video is still running but it won't go 60 fps. When I turn off gpu acceleration, it goes 60 fps. This is a fresh install of ubuntu and I follow this link to install the driver. I follow the instruction until the configuring ones.
I use Ubuntu 16.04.3 with gpu AMD Radeon HD7730.

The Error SS

SS

Can someone tell me what's wrong and how to fix it?

Thanks.

Edit:
mpv configuration: Note: hardware video decoders are NOT compatible with Vapoursynth filters, use --hwdec=no.
VLC configuration: Note 1: Hardware decoding may not be compatible with the Vapoursynth filter! To be investigated...

is this the cause?
