error in generate dash mpd file

[GostGrimmy]

this is my code:

	err := ffmpeg_go.Input(
		"input-filepath",
		ffmpeg_go.KwArgs{
			"re": "",
		},
	).
		Output("path/out.mpd",
			ffmpeg_go.KwArgs{
				"map":    0,
				"c:a":    "aac",
				"c:v":    "libx264",
				"b:v:0":  "750k",
				"s:v:0":  "640x360",
				"vf:v:0": "scale=-1:360",
				//"filter:v":        "fps=24",
				"keyint_min":      "120",
				"g":               "120",
				"sc_threshold":    0,
				"use_timeline":    1,
				"window_size":     5,
				"b_strategy":      "0",
				"bf":              "1",
				"use_template":    "1",
				"adaptation_sets": "\"id=0,streams=v id=1,streams=a\"",
				"f":               "dash",
			},
		).
		OverWriteOutput().
		ErrorToStdOut().
		Run()
	if err != nil {
		fmt.Println(err.Error())
	}

generate ffmpeg command is
ffmpeg -re -i myinput-path/video/1.mp4 -adaptation_sets "id=0,streams=v id=1,streams=a" -b:v:0 750k -b_strategy 0 -bf 1 -c:a aac -c:v libx264 -f dash -g 120 -keyint_min 120 -map 0 -queue_size 60 -s:v:0 640x360 -sc_threshold 0 -use_template 1 -use_timeline 1 -vf:v:0 scale=-1:360 -window_size 5 my-output-path/out.mpd -y
after exec the error is

Error initializing output stream 0:0 --
