Hello.
Thanks for reading my topic.
In WINE Staging previous version (possibly before 7.22) was possibly start MediaCoder having NVENC acceleration without errors.
WINE Staging 7.22 had removed CUDA and NVENC files in both 32 and 64 bits WINE directories
nvapi64
nvcuda
nvcuvid
nvencodeapi64
I for testing in WINE Staging 7.10 was copied the files correctly libraries 32 and 64 bits in WINE prefix and also others files in
/opt/wine-staging/lib/x86_64-unix
nvcuda.dll.so
nvcuvid.dll.so
nvencodeapi.dll.so
/opt/wine-staging/lib/x86_64-windows
nvapi64.dll
nvcuda.dll
nvcuvid.dll
nvencodeapi64.dll
/opt/wine-staging/lib64/x86_64-unix
nvcuda.dll.so
nvcuvid.dll.so
nvencodeapi.dll.so
/opt/wine-staging/lib64/x86_64-windows
nvapi64.dll
nvcuda.dll
nvcuvid.dll
nvencodeapi64.dll
Doing an regedit search not have keys with names "cuda" and "nvenc".
MediaCoder enabling NVENC show message was possible find "NVENC acceleration" , but not is possible start enconder.
I not have information to figure if the error happening is because was done any changes in WINE recent versions not allow access an codecs files or even the cuda nvenc files not being possible access to host nvidia drivers.
However MediaCoder does enconder if not enabling CUDA NVENC acceleration.
Have an nice week.
