Takes two u32s '''SampleRate''' and '''ChannelCount''' packed as an u64, an u32 '''WorkBufferSize''' and a TransferMemory handle for '''WorkBuffer'''. Returns an [[#IHardwareOpusDecoder]] object. The TransferMemory is created by the user-process with permissions=0.
Takes two s32s '''SampleRate''' and '''ChannelCount''' packed as an u64, an u32 '''WorkBufferSize''' and a TransferMemory handle for '''WorkBuffer'''. Returns an [[#IHardwareOpusDecoder]] object. The TransferMemory is created by the user-process with permissions=0.

Takes two u32s '''SampleRate''' and '''ChannelCount''' packed as an u64. Returns the required size for the decoder's work buffer.
Takes two s32s '''SampleRate''' and '''ChannelCount''' packed as an u64. Returns the u32 required size for the decoder's work buffer. Official user-processes align the output size to page-alignment.
== OpenHardwareOpusDecoderForMultiStream ==
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.
The input buffer is a [[#MultiStreamParameters]] struct. The user-process initializes this struct the same way as [[#GetWorkBufferSizeForMultiStream]], except that an u8-array specified by the user is copied to +0x10 with size '''ChannelCount''', when '''ChannelCount''' above 0.
== GetWorkBufferSizeForMultiStream ==
Takes a type-0x19 input buffer. Returns the u32 required size for the decoder's work buffer. Official user-processes align the output size to page-alignment.

=== DecodeInterleavedOld ===
=== DecodeInterleavedOld ===
Takes a type-5 input buffer ('''OpusDataIn''') and a type-6 output buffer ('''PcmDataOut'''). Decodes the Opus source data to PCM and returns two u32s '''DecodedSampleCount''' and '''DecodedDataSize'''.
Takes a type-5 input buffer ('''OpusDataIn''') and a type-6 output buffer ('''PcmDataOut'''). Decodes the Opus source data to PCM and returns output s32 '''DecodedDataSize''' and s32 '''DecodedSampleCount'''.
Calls the same func as [[#DecodeInterleaved]] internally with flag=0 and out_u64_ptr=NULL.
=== SetContext ===
=== SetContext ===
Takes a type-5 input buffer ('''DecoderContextIn'''). Sends the unknown context data to the hardware decoder. The input buffer is unused.
=== DecodeInterleavedForMultiStreamOld ===
Takes a type-5 input buffer ('''OpusDataIn''') and a type-6 output buffer ('''PcmDataOut'''). Decodes the Opus source data to PCM and returns output s32 '''DecodedDataSize''' and s32 '''DecodedSampleCount'''.
Calls the same func as [[#DecodeInterleavedForMultiStream]] internally with flag=0 and out_u64_ptr=NULL.
=== SetContextForMultiStream ===
Takes a type-5 input buffer ('''DecoderContextIn'''). Sends the unknown context data to the hardware decoder.
Takes a type-5 input buffer ('''DecoderContextIn'''). Sends the unknown context data to the hardware decoder.
=== DecodeInterleavedWithPerfOld ===
Takes 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 output u64 is ignored by official user-processes.
Calls the same func as [[#DecodeInterleaved]] internally with flag=0.
=== DecodeInterleavedForMultiStreamWithPerfOld ===
Takes 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 output u64 is ignored by official user-processes.
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.
