Embodiment Construction

[0032] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0033] see figure 1 , is a schematic flow chart of the NTFS-based media library scanning method in the first embodiment of the present invention, and the method includes the following steps:

[0034] Step S10, selecting a file as the file to be scanned.

[0035] Step S11, judging whether the file to be scanned contains the first data stream identified by the media file. If yes, go to step S12; otherwise, go to step S14.

[0036] Wherein, the first data stream identified by the media file is created when the file is first scanned and parsed into a media file.

[0037] Step S12, if the file to be scanned contains the first data stream identified by the media file, it is judged whether the time stamp recorded in the first data stream is late...

Abstract

The invention provides a media library scanning method and device based on NTFS. The method includes selecting a file as the file to be scanned; judging whether the file to be scanned contains first data stream of a media file identifier, wherein the first data stream of the media file identifier is built when the file is first scanned and analyzed to be the media file; if yes, judging whether the timestamp of the first data stream record is later than modification time of the file to be scanned; if yes, skipping the file to be scanned and selecting the next file as the file to be scanned; if no, scanning and analyzing the file to be scanned. By means of the method and device, the technical problems of low scanning speed and resource waste caused by the fact that the media file is analyzed repeatedly and all the files are scanned are solved.

Description

technical field [0001] The invention relates to a media library scanning method, in particular to an NTFS-based media library scanning method and device. Background technique [0002] The media library is actually a database, which stores the information of multimedia files, such as media file title, album, bit rate, width and height, and access path. Android, Linux, and Windows operating systems all use media libraries. [0003] Data stream refers to the data stream function in the NTFS (New Technology File System) new technology file system. In the NTFS file system, each file can have multiple data streams, and the data content of the file itself is a main data stream without a name. , in addition to the file can also have any number of named slave data streams. In addition to this main data stream, we can also create any number of named slave data streams. The naming convention of the data stream is as follows: file name: data stream name. For example, "Home.mkv", thi...
