The problem of calling Nvidia GPU video compression (ffmpeg) in the windows system service

When calling Nvidia GPU video compression (ffmpeg) in the Windows system service, the bit rate cannot be controlled and the output video stream cannot be decoded. What should I do?

The FFMPEG is using Video Codec SDK for video transcoding, bit rate should be adjustable. You might check the documentation here: Using FFmpeg with NVIDIA GPU Hardware Acceleration :: NVIDIA Video Codec SDK Documentation

GPU accelerated FFMPEG can be downloaded here: FFmpeg | NVIDIA Developer

If the issue persisted, please provide detail information about how to reproduce it.
