VDPAU H264 Decoding

[rogurotus]

Implementation of hardware decoding via VDPAU

Problem to solve

1. Solves the license problem when using the h264 software decoder
2. Improves energy efficiency, reduces CPU load

Proposal

1. Recheck frame info parsing
2. Fix frame references

Prior art

FFmpeg (Check the license)

Alternatives

Use VA-API (Check NVIDIA driver support)
