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