Description

Below is a collection of four character codes (TFourCC) used in S60 3rd Edition devices.

TFourCC is a class that holds a four character code, representing a supported (audio) data encoding type. A four character code is packed into a single TUint32. FourCC codes are used to identify codecs when initializing an instance of one of the audio classes (for example, CMdaAudioOutputStream, CMdaAudioOutputStream, or CMMFDevSound).

Note that the list of supported codecs may vary between devices.

Solution

// 8-bit PCM
const TUint32 KMMFFourCCCodePCM8     = 0x38502020; //  (' ',' ','P','8')

// 8-bit Unsigned PCM
const TUint32 KMMFFourCCCodePCMU8    = 0x38555020; //  (' ','P','U','8')

// 16-bit PCM
const TUint32 KMMFFourCCCodePCM16    = 0x36315020; //  (' ','P','1','6')

// 16-bit Unsigned PCM
const TUint32 KMMFFourCCCodePCMU16   = 0x36315550; //  ('P','U','1','6')

// MSB (Big Endian) 16-bit PCM
const TUint32 KMMFFourCCCodePCM16B   = 0x42363150; //  ('P','1','6','B')

// MSB (Big Endian) 16-bit Unsigned PCM
const TUint32 KMMFFourCCCodePCMU16B  = 0x42365550; //  ('P','U','6','B')

// IMA ADPCM
const TUint32 KMMFFourCCCodeIMAD     = 0x44414d49; //  ('I','M','A','D')

// IMA Stereo ADPCM
const TUint32 KMMFFourCCCodeIMAS     = 0x53414d49; //  ('I','M','A','S')

// A-LAW
const TUint32 KMMFFourCCCodeALAW     = 0x57414c41; //  ('A','L','A','W')

// µ-LAW
const TUint32 KMMFFourCCCodeMuLAW    = 0x57414c75; //  ('u','L','A','W')

// GSM 610
const TUint32 KMMFFourCCCodeGSM610   = 0x364d5347; //  ('G','S','M','6')

// AMR-NB (Narrow-Band)
const TUint32 KMMFFourCCCodeAMR      = 0x524d4120; //  (' ','A','M','R')

// Advanced Audio Codec (MPEG4, Audio layer 3)
const TUint32 KMMFFourCCCodeAAC      = 0x43414120; //  (' ','A','A','C')

// AMR Wideband
const TUint32 KMMFFourCCCodeAWB      = 0x42574120; //  (' ','A','W','B')

// MPEG, Audio layer 3
const TUint32 KMMFFourCCCodeMP3      = 0x33504d20; //  (' ','M','P','3')

// ATRAC3
const TUint32 KMMFFourCCCodeATRAC3   = 0x33525441; //  ('A','T','R','3')

// SBC
const TUint32 KMMFFourCCCodeSBC      = 0x43425320; //  (' ','S','B','C')

// AAC Variant ADTS
const TUint32 KMMFFourCCCodeADTS     = 0x53544441; //  {'A','D','T','S'}

// Windows Media Audio (WMA)
const TUint32 KMMFFourCCCodeWMA      = 0x414d5720; //  {' ','W','M','A'} 

// FourCC used if the actual fourCC is not known or not applicable
const TUint32 KMMFFourCCCodeNULL     = 0x4c4c554e; //  ('N','U','L','L')
