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.
