== Initialize ==

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.

== GetWorkBufferSize==

Takes two ~~u32s~~ '''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.

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.

Line 610:

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 0x110-byte struct. The first 4 ~~u32s~~ are '''SampleRate''', '''ChannelCount''', '''TotalStreamCount''', and '''StereoStreamCount''' while the rest is cleared to zeros.

The input buffer is a 0x110-byte struct. The first 4 s32s are '''SampleRate''', '''ChannelCount''', '''TotalStreamCount''', and '''StereoStreamCount''' while the rest is cleared to zeros.
