AAC Encoder WindowsThe Microsoft Media Foundation AAC encoder is a Media Foundation Transform that encodes Advanced Audio Coding AAC Low Complexity LC profile, as defined by ISOIEC 1. MPEG 2 Audio Part 7. The AAC encoder does not support encoding to any other AAC profiles, such as Main, SSR, or LTP. It does not support encoding to the MPEG 4 extensions HE AAC v. Class Identifier. The class identifier CLSID of the AAC encoder is CLSIDAACMFTEncoder, defined in the header file wmcodecdsp. Media Types. The AAC encoder supports the following media types. You can set the types in either orderinput type first, or output type first. Input Types. Set the following attributes on the input media type. Mpt 3.2.1.

MFMTAACPAYLOADTYPEThe AAC payload type. Optional. If set, the value must be zero, indicating that the stream contains rawdatablock elements only. Optional. If the attribute is not set, the default value is zero, indicating that the stream contains rawdatablock elements only raw AAC. In Windows 7, if this attribute is set, the value must be zero. Starting in Windows 8, the value can be 0 raw AAC or 1 ADTS AAC. MFMTAACAUDIOPROFILELEVELINDICATIONThe AAC audio profile and level. Optional. The following values are supported 0x. A0x. 2B0x. 2C0x. 2E0x. F0x. 30. 0x. 31. 0x. After the output type is set, the AAC encoder updates the type by adding the MFMTUSERDATA attribute. This attribute contains the portion of the HEAACWAVEINFO structure that appears after the WAVEFORMATEX structure that is, after the wfx member. This is followed by the Audio. Specific. Config data, as defined by ISOIEC 1. Each output sample contains one compressed AAC frame with no header.

The MFMTAACPAYLOADTYPE attribute, if present in the output type, must be set to zero to indicate this payload type. Each output sample contains one compressed AAC frame corresponding to 1. PCM samples. For example, at 4. Khz sampling rate, the duration of one compressed frame is 2. If MFMTAACPAYLOADTYPE is zero the default value, each output sample contains one rawdatablock element as defined by ISOIEC 1. Example Media Types.

In the current implementation, every input sample must have a valid time and duration. To set the sample time, call IMFSample Set. Sample. Time. To set the sample duration, call IMFSample Set. Sample. Duration. If the sample time is not set, the encoders IMFTransform Process. Input method returns MFENOSAMPLETIMESTAMP. If the sample duration is not set, the Process.

Per. Channel is the number of PCM audio samples per channel in the input buffer, and n. Samples. Per. Sec is the sampling rate, in samples per second. Note  Due to a bug in the current implementation, if the sample duration is set to zero, the Process. Input call succeeds, but a subsequent call to IMFTransform Process. Output will throw a divide by zero exception. To avoid this error, set a valid nonzero duration on each input sample. Requirements. Minimum supported client.
