Problems detecting the 'video=' parameter in dshow

I'm trying to translate the command ffmpeg -f dshow -i video="HP TrueVision HD Camera" -vframes 1 out.png to go-ffmpeg.

In the process I stay something like this

var err = ffmpeg.Input(fmt.Sprintf("video=\"%s\"", cam.cameraName), ffmpeg.KwArgs{
        "f": "dshow",
    }).Output("a.png", ffmpeg.KwArgs{
        "vframes": "1",
    }).ErrorToStdOut().Run()

But when I run this command, the library gives me this output with an error. According to the library log the command is fine but the error is strange.

go run .\cli\main.go

The command even shows in console I run it on my own and it works, but inside the library it fails
