问题描述
我正在尝试从URL拆分视频....这是我的CMD命令:
I am trying to split a video from a URL.... this is my CMD command:
ffmpeg -i 'https://mediasite-ondemand.maastrichtuniversity.nl/MediasiteDeliver/ondemand/MP4Video/90e0ea3d-4087-4a3d-8a78-7acf7906c4cb.mp4?playbackTicket=fb14f2f3baf84412bc6463d4e312ec27&site=mediasite.maastrichtuniversity.nl' -ss 00:00:00 -t 0:25:00 -c copy SplicedVid.wav
为什么返回:
'site'不被识别为内部或外部命令，可操作的程序或批处理文件.
'site' is not recognized as an internal or external command, operable program or batch file.
我的版本:
ffmpeg -version output:

推荐答案
将URL用引号引起来:
Put the URL in quotes:
ffmpeg -i "https://mediasite-ondemand.maastrichtuniversity.nl/MediasiteDeliver/ondemand/MP4Video/90e0ea3d-4087-4a3d-8a78-7acf7906c4cb.mp4?playbackTicket=fb14f2f3baf84412bc6463d4e312ec27&site=mediasite.maastrichtuniversity.nl" -t 00:25:00 output.wav
