```
public final class POBMediaViewRendererHelper
 implements POBImageDownloadManager.POBImageDownloadListener
                    
```
Helper class for managing media view rendering in native ads. This helper encapsulates video and image rendering logic for native ad media views, providing a reusable component for both standard rendering and SDK bidding integrations.
Key responsibilities:
- Managing video asset loading via POBVideoRenderer
- Managing image downloading via POBImageDownloadManager
- Tracking video state (loading, rendered, complete, failed)
- Managing the media view container (FrameLayout) - created internally
- Forwarding video events to listeners
Usage:
- For bidder flow: Use mediaView directly as the media view container
- For template flow: Add mediaView to the template's media view container

POBMediaViewRendererHelper(Context context)
```
    Parameters:
    
    context - Valid context
- Method Detail
  - getMediaView
```
 final FrameLayout getMediaView()
```
    The media view container that holds video player or main image. Created internally and can be used directly (bidder flow) or added to a parent container (template flow).
  - getListener
```
 final POBMediaViewRendererHelper.Listener getListener()
```
    Listener for media view helper callbacks
  - setListener
```
 final Unit setListener(POBMediaViewRendererHelper.Listener listener)
```
    Listener for media view helper callbacks
  - loadMedia
```
 final Unit loadMedia(POBNativeAdResponse nativeAdResponse, POBBid bid, Integer mediaViewImageAssetId)
```
    Loads the media assets (video and/or image) for the native ad. This method should be called after the native ad response is received.
    
    Parameters:
    
    nativeAdResponse - The native ad response containing assets
    
    bid - The bid object for rendering context
    
    mediaViewImageAssetId - The asset ID for the fallback image (icon or main image).
  - destroy
```
 final Unit destroy()
```
    Destroys the helper and releases all resources
  - getMediaAspectRatio
```
 final Float getMediaAspectRatio()
```
    Returns the aspect ratio of the video asset with fallback to image asset.
    <p> Checks in the following order: 1. Video asset - reads from VAST player's selected media file 2. Image asset - reads dimensions from image asset For video assets, the aspect ratio is derived from the width and height attributes of the MediaFile as defined in the VAST specification. Both attributes are required. For image assets, the aspect ratio is calculated using the w and h attributes of the image/ icon asset as defined in the NATIVE ad specification. </p>
    
    Returns:
    
    aspect ratio as Float, or 0f if not available
  - onComplete
```
 Unit onComplete(Map<String, Bitmap> downloadedImages)
```
