##### Out-stream Video

Michao adapter supports outstream video renderer in two ways: using your own renderer or using ours on Prebid.org.

#### Native

Example:

```js
var nativeAdUnit = {
  code: "myNativeAdUnit",
  mediaTypes: {
    native: {
      ortb: {
        assets: [
          {
            id: 1,
            required: 1,
            img: {
              type: 3,
              w: 150,
              h: 50,
            },
          },
          {
            id: 2,
            required: 1,
            video: {
              minduration: 0,
              maxduration: 120,
              mimes: ["video/mp4"],

            },
          },
        ],
