AssetBundles for Video in ios

Hello
i want to include a 2k Video and 4k Video in AssetBundel and i'll build the project for IOS only ,
so i can use xcassetes Catalog to include 2k video for 1Gb ram Device or less and the 4k for 2 Gb ram
i tried use AssetBundleManager by unity but i'm not able to create xcassetes when build IOS , and i need to get the path for specific asset to play it with external plugin
