Huge watt when docoding

[linzj]

When decoding using nvidia-vaapi, which actually working on NVDEC, consume 108 watt decoding a 4K HEVC.
Or 38 watt if using VDPAU.

Maybe we should consider briding on VDPAU not NVDEC?

Covered in #74, but yes, the cuda requirement forces the GPU into a high power level. vdpau doesn't have any way to do efficient interop for surface export, which is why it can't be used for the implementation.

Thanks for the reply and I have checked vdpau API，I understood the point you have mentioned.I think this is the point VDpau is missing.

Nothing we can do here so i closed the issue
