NVEncC (x64) 2.07 by rigaya [NVENC API v6.0], build May 29 2016 23:27:29 reader: raw, avs, vpy, avcuvid [H.264/AVC, MPEG1, MPEG2] Usage: NVEncC.exe [Options] -i <input file> -o <output file> Input can be avs, raw YUV, YUV4MPEG2(y4m). When Input is in raw format, fps, input-res is required. Ouput format will be in raw H.264/AVC or H.265/HEVC ES.
