I used Garrett's answer and modified it (including one or two bug fixes). I also used send_data instead of reading from a file:

  def stream_data data, options={}
    range_start = 0
    file_size = data.length
    range_end = file_size - 1
    status_code = "200"

    if request.headers["Range"]
      status_code = "206"
      request.headers['range'].match(/bytes=(\d+)-(\d*)/).try do |match|
        range_start = match[1].to_i
        range_end = match[2].to_i unless match[2]&.empty?
      end
      response.header["Content-Range"] = "bytes #{range_start}-#{range_end}/#{file_size}"
    end

    response.header["Content-Length"] = (range_end - range_start + 1).to_s
    response.header["Accept-Ranges"] = "bytes"

    send_data(data[range_start, range_end],
              filename: options[:filename],
              type: options[:type],
              disposition: "inline",
              status: status_code)
  end
