public static AssetBundleRecompressOperation RecompressAssetBundleAsync(string inputPath, string outputPath, BuildCompression method, uint expectedCRC, ThreadPriority priority);

Parameters

inputPath Path to the AssetBundle to recompress.
outputPath Path to the recompressed AssetBundle to be generated. Can be the same as inputPath.
method The compression method, level and blocksize to use during recompression. Only some BuildCompression types are supported (see note).
expectedCRC CRC of the AssetBundle to test against. Testing this requires additional file reading and computation. Pass in 0 to skip this check. Unity does not compute a CRC when the source and destination BuildCompression are the same, so no CRC verification takes place (see note).
priority The priority at which the recompression operation should run. This sets thread priority during the operation and does not effect the order in which operations are performed. Recompression operations run on a background worker thread.

Description

Asynchronously recompress a downloaded/stored AssetBundle from one BuildCompression to another.

Method must be a BuildCompression whose name ends with Runtime, for example LZ4Runtime, otherwise an ArgumentException is thrown. When the destination BuildCompression is the same as the source, this becomes a copy operation internally, and Unity does not compute a CRC of the uncompressed data. Passing in a non-zero expectedCRC in this case raises a warning, and no CRC validation takes place.
