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 anIMAAdsRenderingSettingsinstance to pass this information at the time of Ads Manager initialization.
