◆  SetCallbackHandler()

MAXON_METHOD Result <void> SetCallbackHandler ( const ExifDataHandler &  handleExifData )

Subscribes to the Exif data stream. So if the media converter triggers the callback as soon as the exif data is available.

参数
[in] handleExifData A handler which is called from the input media converter to signal that the exif data is available for this stream.
返回
OK on success.

◆  HandleExifData()

MAXON_METHOD Result <void> HandleExifData ( const ExifRef &  exifData )

◆  FinishStream()

MAXON_METHOD Result <void> FinishStream ( const MediaStreamProperties &  props )
