I found implementations of fetching Metadata of AVAsset. But its possible to set AV MetaData using AVMetaDataItem. This class MP42AVFImporter.m in This Example has a method named -(MP42Metadata*)convertMetadata they have manipulated metadata and also they have added there own artwork image... have a look...
