Ffmpeg 无法使用h264_cuvid解码视频

我使用的是nvidia GTX 1080Ti，驱动程序版本：387.12

我正在使用以下命令：

ffmpeg -c:v h264_cuvid -i http://stream:port/channel output.mkv 

并获得以下输出：

您知道这个问题吗？

这是一个很长的命令。修复了“File'output.mkv”格式已经存在的问题。是否覆盖？您指的是这个问题吗？如果是这种情况，只需在命令开头添加-y选项即可覆盖文件。ffmpeg-y-c:vh264_cuvid-i输出。mkv@Ahmed_Faraz这不是错误。错误是无法解码输入流。没有CUVID它能用吗？你有一个可以测试这个流的URL吗？@slhck 21是的，你是对的。问题是，如果没有CUVID，我无法解码这个流。当我使用CPU解码时，它工作正常。
