🚀 Feature Request

GPU decoding using Nvidia libraries

🔈 Motivation

Currently, the main bottleneck to speed is GPU decoding. Perhaps integrating NVidia libraries (DALI) would improve the performance.

Note: DALI library turns out to be very limited. It refuses to decode VFR video, which for the sampling use case is a must.

PyNvVideoCoded seems to be still supported, so there's hope for future improvement: https://docs.nvidia.com/video-technologies/pynvvideocodec/pynvc-api-prog-guide/index.html#video-demuxing__video-demuxing-api-details
