Remarks
This attribute applies to presentation descriptors that were generated from the ASF ContentInfo Object by a call to IMFASFContentInfo::GeneratePresentationDescriptor. The format of the byte array is as follows:
| Language List Object field | Data type | Size | Description |
|---|---|---|---|
| Language ID Records Count | DWORD | 4 bytes | Number of languages |
| Language ID Records | BYTE[] | Varies | Array of language strings (see below). |
The first DWORD is the number of languages, followed by an array of language identifier strings. Each string has the following format:
| Language List Object field | Data type | Size | Description |
|---|---|---|---|
| Language ID Length | DWORD | 4 bytes | The length of the string in bytes, including the size of the trailing NULL character. |
| Language ID | WCHAR[] | Varies | A null-terminated string containing the RFC 1766 language name. |
Each string is a language tag compliant with RFC 1766.
Use this attribute only for backward compatibility with the enumeration order of the IWMReaderAdvanced4 interface in the Windows Media Format SDK. The language strings are stored in a different order in the MF_PD_ASF_LANGLIST attribute.
