Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 1, a schematic diagram of an apparatus for automatically completing and arranging video meta information according to an embodiment of the present invention includes a multimedia server 101, a video playing device 102, and a storage device 103; the multimedia server 101 is connected with a video playing device 102, and the video playing device 102 is connected with a storage device 105; the video playing device 102 includes a video information complementing unit 103, and the video information complementing unit 103 includes a first video meta-information obtaining module 111, an audio data obtaining module 112, an audio fingerprint generating module 113, a communication module 114, and a first writing module 115. The video playing device is a device with a video playing function, and can be a mobile phone, a PC, a tablet and the like. The multimedia server is a server storing a plurality of video files, and in the present embodiment, the video files stored on the multimedia server have complete video meta information. The multimedia server and the video playing device can be connected through wireless connection or wired connection. The storage device can be embedded in the video playing device, or can be externally connected with the video playing device.
The first video meta-information obtaining module 111 is configured to obtain a video file from the storage device 105 and analyze first video meta-information corresponding to the video file, where the video file includes first video meta-information, video data, and audio data;
the audio data obtaining module 112 is configured to parse a video file and obtain audio data corresponding to the video file;
the audio fingerprint generating module 113 is configured to generate an audio fingerprint according to audio data of a video file;
the communication module 114 is configured to send the audio fingerprint to a multimedia server;
the multimedia server 101 is configured to query second video meta-information corresponding to the audio fingerprint according to the audio fingerprint, and send the second video meta-information to the video playing device;
the communication module 114 is further configured to receive second video meta information, and the first writing module 115 is configured to write the second video meta information into a video file to replace the original first video meta information of the video file.
When the device for automatically completing and arranging the video meta-information is used, firstly, the first video meta-information acquisition module acquires a video file from the storage equipment and analyzes the first video meta-information corresponding to the video file. The video file, i.e., the offline video file, includes first video meta information, video data, and audio data. The video data is video code stream data in the video file, and the audio data is audio code stream data in the video file. The storage device is an electronic element with a storage function and can be a hard disk, a U disk and the like. The video metadata is used for representing the basic information of the video file. In this embodiment, the video metadata includes a sampling rate corresponding to video data, a sampling rate corresponding to audio data, a thumbnail corresponding to a video file, and a profile. In other embodiments, the video metadata may also include keywords (used to retrieve parameters of the video), duration, format, size, caption content, actor information, etc. to which the video data corresponds. The first video meta-information is video meta-information whose information is not complete, and the information is incomplete, so that the initial video meta-information (first video meta-information) of the offline video needs to be complemented so as to manage the offline video, such as classification, search, and the like.
And the audio data acquisition module analyzes the video file and acquires audio data corresponding to the video file, and the audio fingerprint generation module generates an audio fingerprint according to the audio data of the video file. Audio fingerprinting technology refers to the extraction of unique digital features in a piece of audio in the form of an identifier by a specific algorithm for identifying a large number of sound samples or tracking the location of location samples in a database. The audio fingerprint is used as a core algorithm of a content automatic identification technology, and is widely applied to the fields of music identification, copyright content monitoring and broadcasting, content library duplicate removal, television second screen interaction and the like. The generated audio fingerprint can be used as identification information of the video file, and the video file is retrieved by adopting the identification information.
And then the communication module sends the audio fingerprint to a multimedia server, and the multimedia server inquires second video meta-information corresponding to the audio fingerprint according to the audio fingerprint and sends the second video meta-information to the video playing equipment. The second video meta-information is video meta-information stored on the multimedia server, i.e. relatively complete video meta-information. In short, each video file corresponds to an audio fingerprint, and each video file stored on the multimedia server corresponds to a second video meta-information, so that the second video meta-information corresponding to the audio fingerprint can be queried and obtained by using the audio fingerprint as an index. And because the audio fingerprint is generated by acquiring the audio of the offline video, the acquired second video meta-information is the video meta-information corresponding to the relatively complete offline video.
And then the communication module receives the second video meta-information, and the first writing module writes the second video meta-information into the video file to replace the original first video meta-information of the video file. After the video playing device receives the second video meta-information, the video meta-information (the first video meta-information) in the original video file can be complemented, specifically: and replacing the information on the video metadata field for storing the video file in the video code stream data with second video metadata. Therefore, the automatic completion of the video meta information of one video file is completed, and then the video files can be classified according to actual needs, so that the further management is facilitated.
In some embodiments, the storage device stores a plurality of video files, the video playing device 102 further includes a video sorting unit 104, and the video sorting unit 104 includes a second video meta-information obtaining module 121, a cluster analysis module 122, a second writing module 123, and a display module 124. The second video meta-information acquisition module is used for acquiring video meta-information corresponding to all video files in the storage device; the cluster analysis module is used for carrying out cluster analysis on video meta-information corresponding to all the video files and determining classification names corresponding to a plurality of video files, wherein each video file corresponds to one classification name; the second writing module is used for writing the classification name into the video meta information of the video file corresponding to the classification name; the display module is further used for receiving a first instruction and displaying the video files corresponding to the video meta information with the same classification name. In this embodiment, the video meta-information is second video meta-information.
After the video meta-information in the offline video file is completed, different video files can be classified according to the video meta-information. For example, video files containing the same star as the lead actor information in the video meta information can be classified into one category, and the name of the star is used as the classification name of the video; for another example, video files with a duration greater than 1 hour in the video meta information may be classified into one category, and "duration >1 hour" is used as a category name of the video files meeting the condition. The clustering analysis can be realized by a clustering analysis algorithm, and the general principle is that after all video files are classified, videos in the same category have the same elements in video meta-information as much as possible, such as duration, title, director information and the like.
After the cluster analysis is completed, each offline video file has its corresponding classification name, that is, the classification name corresponding to the video file is written in the video metadata field of each video file. Then, different video files can be classified according to the classification names, for example, the same number of folders can be newly created according to the classification names, each folder corresponds to a classification name, and the video files with the same classification name are stored in the folder corresponding to the classification name. When the user clicks the folder, a first instruction is triggered, and the video files corresponding to the video meta information with the same classification name are displayed. Through the scheme, different video files can be classified after the video meta-information is completed, so that the user can traverse, search and check conveniently, and the sensory experience of the user is greatly improved.
Referring to fig. 2, a flowchart of a method for automatically completing and arranging video meta-information according to an embodiment of the present invention is shown, where the method is applied to a device for automatically completing and arranging video meta-information, where the device includes a multimedia server, a video playing device, and a storage device; the multimedia server is connected with video playing equipment, and the video playing equipment is connected with storage equipment; the video playing device comprises a video information complementing unit, wherein the video information complementing unit comprises a first video meta-information acquiring module, an audio data acquiring module, an audio fingerprint generating module, a communication module and a first writing module; the method comprises the following steps:
firstly, in step S201, a first video meta-information obtaining module obtains a video file from a storage device and analyzes first video meta-information corresponding to the video file. The video file includes first video meta information, video data, and audio data. The video data is video code stream data in the video file, and the audio data is audio code stream data in the video file. The storage device is an electronic element with a storage function and can be a hard disk, a U disk and the like. The video metadata is used for representing the basic information of the video file. In this embodiment, the video metadata includes a sampling rate corresponding to video data, a sampling rate corresponding to audio data, a thumbnail corresponding to a video file, and a profile. In other embodiments, the video metadata may also include keywords (used to retrieve parameters of the video), duration, format, size, caption content, actor information, etc. to which the video data corresponds. The first video meta-information is video meta-information whose information is not complete, and the information is incomplete, so that the initial video meta-information (first video meta-information) of the offline video needs to be complemented so as to manage the offline video, such as classification, search, and the like.
Then, the audio data acquisition module analyzes the video file and acquires audio data corresponding to the video file in step S202, and the audio fingerprint generation module generates an audio fingerprint according to the audio data of the video file in step S203. Audio fingerprinting technology refers to the extraction of unique numerical features in a piece of Audio in the form of an identifier by a specific algorithm for identifying a large number of sound samples or tracking the location of a location sample in a database. The audio fingerprint is used as a core algorithm of a content automatic identification technology, and is widely applied to the fields of music identification, copyright content monitoring and broadcasting, content library duplicate removal, television second screen interaction and the like. The generated audio fingerprint can be used as identification information of the video file, and the video file is retrieved by adopting the identification information.
And then, step S204 is carried out, the communication module sends the audio fingerprint to the multimedia server, and step S205 is carried out, the multimedia server inquires second video meta-information corresponding to the audio fingerprint according to the audio fingerprint and sends the second video meta-information to the video playing equipment. The second video meta-information is video meta-information stored on the multimedia server, i.e. relatively complete video meta-information. In short, each video file corresponds to an audio fingerprint, and each video file stored on the multimedia server corresponds to a second video meta-information, so that the second video meta-information corresponding to the audio fingerprint can be queried and obtained by using the audio fingerprint as an index. And because the audio fingerprint is generated by acquiring the audio of the offline video, the acquired second video meta-information is the video meta-information corresponding to the relatively complete offline video.
And then step S206 is entered, the communication module receives the second video meta information, and the first writing module writes the second video meta information into the video file to replace the original first video meta information of the video file. After the video playing device receives the second video meta-information, the video meta-information (the first video meta-information) in the original video file can be complemented, specifically: and replacing the information on the video metadata field for storing the video file in the video code stream data with second video metadata. Therefore, the automatic completion of the video meta information of one video file is completed, and then the video files can be classified according to actual needs, so that the further management is facilitated.
In some embodiments, the storage device stores a plurality of video files, and the video playing device further includes a video sorting unit, where the video sorting unit includes a second video meta-information obtaining module, a cluster analysis module, a second writing module, and a display module. As shown in fig. 2, the method comprises the steps of:
firstly, entering step S301, a second video meta-information acquisition module acquires video meta-information corresponding to all video files in a storage device; and then, the step S302 is carried out, wherein the clustering analysis module carries out clustering analysis on the video meta-information corresponding to all the video files, and the classification names corresponding to a plurality of video files are determined. Each video file corresponds to a category name. And then step S303 is performed, in which the second writing module writes the category name into the video meta information of the video file corresponding to the category name. And then, the display module further receives a first instruction in step S304, and displays the video file corresponding to the video meta information with the same classification name. In this embodiment, the video meta-information is second video meta-information.
After the video meta-information in the offline video file is completed, different video files can be classified according to the video meta-information. For example, video files containing the same star as the lead actor information in the video meta information can be classified into one category, and the name of the star is used as the classification name of the video; for another example, video files with a duration greater than 1 hour in the video meta information may be classified into one category, and "duration >1 hour" is used as a category name of the video files meeting the condition. The clustering analysis can be realized by a clustering analysis algorithm, and the general principle is that after all video files are classified, videos in the same category have the same elements in video meta-information as much as possible, such as duration, title, director information and the like.
After the cluster analysis is completed, each offline video file has its corresponding classification name, that is, the classification name corresponding to the video file is written in the video metadata field of each video file. Then, different video files can be classified according to the classification names, for example, the same number of folders can be newly created according to the classification names, each folder corresponds to a classification name, and the video files with the same classification name are stored in the folder corresponding to the classification name. When the user clicks the folder, a first instruction is triggered, and the video files corresponding to the video meta information with the same classification name are displayed. Through the scheme, different video files can be classified after the video meta-information is completed, so that the user can traverse, search and check conveniently, and the sensory experience of the user is greatly improved.
The method and the device for automatically completing and arranging the video meta-information in the technical scheme are applied to the device for automatically completing and arranging the video meta-information, and the method comprises the following steps: firstly, a first video meta-information acquisition module acquires a video file from a storage device and analyzes first video meta-information corresponding to the video file; then the audio data acquisition module analyzes the video file and acquires audio data corresponding to the video file; then the audio fingerprint generating module generates an audio fingerprint according to the audio data of the video file; then the communication module sends the audio fingerprint to a multimedia server; then the multimedia server inquires second video meta-information corresponding to the audio fingerprint according to the audio fingerprint and sends the second video meta-information to the video playing equipment; and then the communication module receives the second video meta-information, and the first writing module writes the second video meta-information into the video file to replace the original first video meta-information of the video file. By the method, the meta information of the offline video can be supplemented, the basic information contained in the video can be known conveniently, and a user can summarize and sort the video file on the basis, so that the user experience is greatly improved.
