NVEnc is a CLI (Command-Line Interface) software, meant to investigate performance and image quality of HW encoder (NVENC) of NVIDIA.

NVENC is NVIDIA’s encoder. It’s a physical section of our GPUs that is dedicated to encoding only.

This means that your GPU can operate normally regardless of whether you use this region to stream or record.

Other encoders, such as x264 codec, use your CPU to encode, which takes resources away from other programs such as your game.

That’s why using NVENC allows you to play games at a higher framerate and avoid stuttering, giving you and your viewers a better experience.

Changes to NVEnc 7.53:

- Update to ffmpeg dlls to 7.0 on Windows.
+ ffmpeg 7.0
+ libpng 1.4.0 -> 1.4.3
+ expat 2.5.0 -> 2.6.2
+ opus 1.5.2
+ libxml2 2.12.0 -> 2.12.6
+ dav1d 1.3.0 -> 1.4.1
+ libvpl 2.11.0 (new!)
+ nv-codec-headers (new!)
- Now --avsw can specifying the decoder name to be used.
- When --audio-bitrate is not specified, let codec decide it's bitrate instead of setting a default bitrate of 192kbps.
- Don't process audio/subtitle/data tracks specified by --audio-bitrate or --audio-copy.
- Fix problem from NVEnc 7.47 or later that --master-display copy/--max-cll copy was not working correctly.
- Automatically disable --lookahead-level and --tf-level when running on GPUs that do not support them.
