TagsReader.MP4_UniqueFramesCountGet method |

Remarks
Obtains the number of unique frames found inside the MP4 tag. The identifier of each unique frame can be obtained through the TagsReader.MP4_UniqueFramesIdGet method.
Multiple instances of the picture frame can be available inside the same MP4 tag: when this method is called, the enumeration will not keep count of multiple instances of a specific frame but will only report the availability of the frame itself; once the availability of a specific frame is known, single specific picture frames can be enumerated using the TagsReader.MP4_PictureFrameCountGet method.
For further details about methods related to tags reading refer to the TagsReaderMan class.
For details about the reading of tags see the How to read TAG information in sound files tutorial.
