FFMPEG命令（用于捕获关键帧）执行，但不创建输出文件

我尝试使用FFMPEG命令使用最新的FFMPEG exe文件。该命令执行得很好。但输出文件没有被创建。FFMPEG命令（用于捕获关键帧）执行，但不创建输出文件

这是我从DOS提示符尝试的命令。根据同事的评论，这是（命令）工作之前没有任何麻烦。

D:\Utilities\FFMPegVideoManager\FFMPEG_updated\ffmpeg.exe -i 
"M:\content\video.mp4" -y -ss 1 -frames 1 
"E:\frame\testtest.jpg"

执行后的输出是

C:\Users\ABCD>D:\Utilities\FFMPegVideoManager\FFMPEG_updated\ffmpeg.exe -i "M:\FTP Home Directory\LocalUser\WAP_UAT\Processing Folder\wspa1\Delivery\San4\content\0101_eatingredpanda.mp4" -y -ss 1 -frames 1 "E:\sandeep\testtest.jpg"
