A.8 Supported Windows Media File Format (ASF) for Audio Data

Oracle Multimedia supports the Advanced Systems Format (ASF) file format used by Microsoft Windows Media. These files are denoted by the suffix .wma. The Oracle Multimedia objects ORDAudio and ORDDoc can recognize ASF format data and extract attributes about the audio media from the data.

Note:

To access these formats, install the software from the Oracle Multimedia Software section of the Oracle Technology Network Web site at

http://www.oracle.com/technology/products/multimedia/

See Support for the Windows Media File Format (ASF).

See Also:

http://www.microsoft.com/windows/windowsmedia/ for more information about the Advanced Systems Format used by Microsoft Windows Media

The supported Windows Media file extension and MIME type for audio data stored in an ORDAudio object are as follows:

Table A-5 lists the supported Windows Media audio compression format names and format codes for the ASF formats.
