GetWorkBufferSizeEx

Takes a struct #OpusParametersEx. Returns the u32 required size for the decoder's work buffer. Official user-processes align the output size to page-alignment.

OpenHardwareOpusDecoderForMultiStreamEx

Takes a type-0x19 input buffer, an u32 WorkBufferSize and a TransferMemory handle for WorkBuffer. Returns an #IHardwareOpusDecoder object. The TransferMemory is created by the user-process with permissions=0.

Calls the same func as #DecodeInterleavedForMultiStream internally with flag=0.

DecodeInterleaved

Takes an input u8 bool flag, a type-0x5 input buffer (OpusDataIn) and a type-0x46 output buffer (PcmDataOut). Decodes the Opus source data to PCM and returns output s32 DecodedDataSize, s32 DecodedSampleCount, and an u64.

The bool flag indicates whether or not a reset of the decoder context is being requested.

DecodeInterleavedForMultiStream

Takes an input u8 bool flag, a type-0x5 input buffer (OpusDataIn) and a type-0x46 output buffer (PcmDataOut). Decodes the Opus source data to PCM and returns output s32 DecodedDataSize, s32 DecodedSampleCount, and an u64.
