NVEnc Preview
#6
I tried to dump the output of the 2 process.

The output of: "NVEncC64.exe --avhw --input E:\VideoTest\TestSubs\TestSubs-1.mp4 --output-format raw --output -" , is

having removed the option "--lossless" the output is much smaller.

The output of: "ffmpeg.exe -i E:\VideoTest\TestSubs\Test.mkv -vcodec h264 -pix_fmt yuv420p -f rawvideo -" , is

So it seems that the output is the same:

Codec ID                    : V_MPEG4/ISO/AVC
Frame rate                  : 25.000 FPS
Color space                : YUV
Chroma subsampling  : 4:2:0
Bit depth                    : 8 bits
Scan type                  : Progressive 

But is not working.
