OGG file importer - How to work with the Buffer?

USoundFactory::FactoryCreateBinary looks like one hell of a function to override.

Since it looks like you’ve got the raw pcm at some point, perhaps you could just take the **FileType\b], Buffer and BufferEnd like below?

UObject* USoundOggFactory::FactoryCreateBinary
(
	UClass*				Class,
	UObject*			InParent,
	FName				Name,
	EObjectFlags		Flags,
	UObject*			Context,
	const TCHAR*,//		FileType,
	const uint8*&		Buffer,
	const uint8*			BufferEnd,
	FFeedbackContext*	Warn
){
  TArray<uint8> Wav{};
  ConvertOggToPcmThenAddWavFileHeaders(Buffer,BufferEnd,Wav);
  const uint8 *WavBuffer = Wav.GetData();
  const uint8 *const WavBufferEnd = WavBuffer + Buffer.Num();
  return Super::FactoryCreateBinary(
	Class,
	InParent,
	Name,
	Flags,
	Context,
	TEXT("WAV"),
	WavBuffer,WavBufferEnd,
	Warn);
}

The problem with this is, that I don’t know how to do the ConvertOggToPCMThenAddWavFileHeaders().
Because I only have the functions I already described and the “ExpandFile” function is freezing the Editor, while the ReadCompressedData() function didn’t really give me anything.
Its description is:

Decompresses ogg data to raw PCM data.

so I would assume I could use it, but I’m not 100% sure. Will try though.

What do you mean with the Wav Header? I haven’t understood the actual difference between Ogg and Wav yet (in terms how they are build up).
Would I fill the Wav header from the data I got from ReadCompressedInfo? So basically from the FSoundQualityInfo?
Because the Header is just another chunk of bytes after all and I don’t know what part of the Ogg file is used for that.
