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
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.
