**Description**  
Hi, there. I have selected the memory mode and implementing an instance of the ZoomVideoSDKRawDataPipeDelegate. But I don’t get any data from callback functions. I also implemented an instance of ZoomVideoSDKDelegate and get all the callbacks.

**Video SDK version:**

- 1.3.2

**Smartphone:**

- Device: iPhone 13 Pro
- OS: iOS 15.6.1

You need to subscribe to the video pipe delegate on the specific uer:

```auto
user?.getVideoPipe()?.subscribe(with: <#delegate#>, resolution: <#resolution#>)

```

Thanks for the answer, I have already found a solution)

I would like someone to add this step to the iOS documentation, as I found the solution in the Android documentation.
