5.29

Add option to rerun NVEncC in ANSI mode. (--process-codepage os)

The previous NVEnc 5.28 has added Avisynth Unicode support, by running the app using UTF-8 as the codepage. On the other hand this requires Avisynth scripts to be in UTF-8. I had comments from some users that this cause problem with scripts using non-ASCII characters with legacy codepage, and also tools saving scripts in legacy codepage.

"--process-codepage os" is a switch to make the app run in the default codepage set in the OS, which shall allow AviSynth scripts using non-ASCII characters with legacy codepage to work again.

When this option is set, a copy of the exe file will be created in the same directory of the original exe file, and the manifest file of the copy will be modified using UpdateResourceW API to switch back code page to the default of the OS, and then the copied exe will be run, allowing us to handle the AviSynth scripts using legacy code page.


5.28

Add Avisynth Unicode support. ( #309 )

5.24

Move github release binary to VS2019 build.

This might help improve effective encoding performance.
Add option to calculate VMAF score using libvmaf v1.3.15. (--vmaf)
Currently Win x64 only feature.
Please note that vmaf calculation is done by CPU, and is likely to become a performance bottleneck and hurt encoding performance.

This tries to add support for the HEVC 12bit & AV1 hw decode which are the new features in NVENC SDK 11. Please note that these features are not tested at all and may not work, as I don't have Ampere GPUs (RTX30xx), I'm less confident on AV1 as it is a new codec.
