OK, I was able to use my brain and figure this out. It uses a similar method in the link:

For Android:

    public string VideoLength(string url)
    {
        MediaMetadataRetriever retriever = new MediaMetadataRetriever();
        retriever.SetDataSource(url, new Dictionary<string, string>());
        var length = retriever.ExtractMetadata(MetadataKey.Duration);
        var lengthseconds = Convert.ToInt32(length) / 1000;
        TimeSpan t = TimeSpan.FromSeconds(lengthseconds);
        var timeformat = t.ToString();
        return timeformat.ToString();
    }

For IOS:

    public string VideoLength(string url)
    {
       AVAsset avasset = AVAsset.FromUrl((new Foundation.NSUrl(url)));
        var length = avasset.Duration.Seconds.ToString();
        var lengthseconds = Convert.ToInt32(length) / 1000;
        TimeSpan t = TimeSpan.FromSeconds(lengthseconds);
        var timeformat = t.ToString();
        return timeformat.ToString();

    }
