Specify bitrate and media format

  • VAST responses may contain multiple media files with varying bitrates and formats, and the SDK automatically selects the appropriate bitrate based on network conditions (500 kbit/s maximum for cellular and unlimited for WiFi).

  • On iOS, the SDK uses a conservative approach for cellular connections due to limited network speed information.

  • Developers can specify preferred video formats and bitrates using IMAAdsRenderingSettings during Ads Manager initialization to override the SDK's default behavior.

Select platform: HTML5 Android iOS tvOS

VAST responses can contain multiple media files with different bitrates and in different formats. The SDK chooses the appropriate bitrate based on the current network conditions:

  • max 500 kbit/s for cellular connection
  • unlimited for WiFi

Note: iOS does not provide any detailed information on the current network speed, so the iOS SDK tries to be conservative when on cellular connection.

If you want to specify preferred video formats and bitrate, use an IMAAdsRenderingSettings instance to pass this information at the time of Ads Manager initialization.

- (void)adsLoader:(IMAAdsLoader *)loader adsLoadedWithData:(IMAAdsLoadedData *)adsLoadedData {
  self.adsManager = adsLoadedData.adsManager;
  self.adsManager.delegate = self;
  IMAAdsRenderingSettings *settings = [[IMAAdsRenderingSettings alloc] init];
  settings.bitrate = 1024;  // kbits
  settings.mimeTypes = @[ @"video/mp4", @"application/x-mpegURL"];
  [self.adsManager initializeWithContentPlayhead:nil adsRenderingSettings:settings];
}
