[FFmpeg-user] Listing devices

[Cecil Westerhof]

In a script I want to set the default device to the web-cam microphone
if it is connected. With:
    man ffmpeg-devices
I see:
    ffmpeg -list_devices true -f dshow -i dummy

But when executing this I get:
    ffmpeg -list_devices true -f dshow -i dummy

    Unrecognized option 'list_devices'.
    Error splitting the argument list: Option not found

So there is an error in the documentation. Also: how do I get a list
of possible input devices?
