vlc on command line

[Peter S]

I want to rotate 90° a short mp4 video with following mp4-rotate.cmd:

"C:\Program Files\VideoLan\VLC\vlc.exe" -I dummy -vvv ^
.\20170804_212037_1.mp4 ^
--transform-type=90:standard{access=file,mux=mp4, dst=D:\20170804_212037_1_rot90.mp4} ^
vlc://quit

But there is no putput. Where is my bug?

Thanks for answer
