FFMPEG NVENC 编码与 Windows10

Question

我不得不重新安装 Windows 10，因为 windows.在重新安装之前，我有完全相同的代码工作，但是在我无法让它工作之后。

我正在使用最新的 nvidia 驱动程序 416.16
我安装了 VisualStudio 和 Cuda Toolkit
2x 1080TI

使用 ffmpeg 4.0.2:

T:\ffmpeg\bin\4.0.2\ffmpeg.exe -c:v h264_cuvid -i "T:\Streams\01-ready\2018-10-10 21-19-21.mp4" -i "T:\Streams\10-source\kpg-logo.png" -filter_complex "overlay=10:10" -b:v 24000k -c:v h264_nvenc -c:a copy "T:\Streams\02-encoded\2018-10-10 21-19-21_watermarked.mp4"

输出:

现在仍然有问题，即使使用简单的命令:

当其他进程正在运行访问视频卡时，遇到了类似的结果。只是让程序打开(不主动编码或以其他方式需要硬件加速)会导致冲突。
