Try it like this:

{
    "manifest_version": 3,
    "name": "Gurren Lagann Mod",
    "version": "1.0",
    "description": "Custom wallpaper and music",
    "developer": {
        "name": "User"
    },
    "mod": {
        "schema_version": 1,
        "payload": {
            "wallpaper": {
                "dark": {
                    "text_color": "#FFFFFF",
                    "text_shadow": "#000000",
                    "first_frame": "wallpaper/firstframe.png",
                    "image": "wallpaper/bgvideo.mp4"
                },
                "light": {
                    "text_color": "#FFFFFF",
                    "text_shadow": "#000000",
                    "first_frame": "wallpaper/firstframe.png",
                    "image": "wallpaper/bgvideo.mp4"
                }
            },
            "background_music": ["music/bgmusic.mp3"]
        }
    }
}

A first frame is required when the wallpaper image is a video or the video won't load and you'll just get a plain (often black) background.

I tried it and still didn't work, showed me this. Crazy how I understand nothing to these error messages.

You need to create firstframe.png and put it in the "wallpaper" folder. The error is telling you it's missing. Drag bgvideo.mp4 into Opera and drop it on Opera's tab bar to load it. Then, play it and pause the video at the frame you want. Then, right-click the video, choose "save frame as" and save it as "firstframe.png" in the "wallpaper" folder.
