# MediaParamsEvent

> Event emitted when server-pushed media params are applied.

Event emitted when the server pushes media params.

The event is emitted whether or not the constraints were applied — read [`applied`](#applied) to tell the two apart. A push naming a leg this call does not hold emits nothing at all, because the event carries no leg identity to report it against.

## **Properties**

**`applied`** `boolean` — required

`false` when the constraints did not reach every sender of a pushed kind: the sender carries media the SDK did not capture, the browser refused the constraints and re-acquisition failed, or the leg sends no media of that kind at all.

---

**`audio`** `MediaTrackConstraints`

Audio constraints pushed by the server, if any. See [`MediaTrackConstraints`](https://developer.mozilla.org/en-US/docs/Web/API/MediaTrackConstraints).

---

**`timestamp`** `number` — required

Timestamp when the event occurred (epoch ms).

---

**`video`** `MediaTrackConstraints`

Video constraints pushed by the server, if any. See [`MediaTrackConstraints`](https://developer.mozilla.org/en-US/docs/Web/API/MediaTrackConstraints).
