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 [[#OpusMultiStreamParameters]] 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.

The input buffer is a [[#OpusMultiStreamParameters]] struct.

== OpenHardwareOpusDecoderEx ==
Takes a struct [[#OpusParametersEx]] and a u32 '''WorkBufferSize''' and a TransferMemory handle for '''WorkBuffer'''. Returns an [[#IHardwareOpusDecoder]] object. The TransferMemory is created by the user-process with permissions=0.

When ''UseLargeFrameSize'' in the parameter struct is 1 a larger output buffer that can store 120ms opus frames is used vs the default of 40ms.

== 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.

The input buffer is a [[#OpusMultiStreamParametersEx]] struct. When ''UseLargeFrameSize'' is 1 a larger output buffer that can store 120ms opus frames is used vs the default of 40ms.

== GetWorkBufferSizeForMultiStreamEx ==
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.

The input buffer is a [[#OpusMultiStreamParametersEx]] struct.

== IHardwareOpusDecoder ==
This is "nn::codec::detail::IHardwareOpusDecoder".

=== DecodeInterleavedOld ===
Takes a type-0x5 input buffer ('''OpusDataIn''') and a type-0x6 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 ===
Takes a type-0x5 input buffer ('''DecoderContextIn'''). Sends the unknown context data to the hardware decoder. The input buffer is unused.

=== DecodeInterleavedForMultiStreamOld ===
Takes a type-0x5 input buffer ('''OpusDataIn''') and a type-0x6 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-0x5 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.

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