Property Value

A StreamFormatType enumeration value indicating which streams the target can have.

Gets value that indicates which streams the target format can have. The format to be used for the converted file. This includes the file format, any special settings used by that format, and which audio and/or video codec is to be used for the conversion, and any special settings used by the codecs. For a list of possible values, refer to StreamFormatType constants. Individual values can be combined by using the bitwise OR operator.
