It should be further understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.
As used in this specification and the appended claims, the term "if" may be interpreted contextually as "when", "upon" or "in response to a determination" or "in response to a detection". Similarly, the phrase "if it is determined" or "if a [ described condition or event ] is detected" may be interpreted contextually to mean "upon determining" or "in response to determining" or "upon detecting [ described condition or event ]" or "in response to detecting [ described condition or event ]".
In order to explain the technical solution of the present application, the following description will be given by way of specific examples.
In practical application, after a communication connection is established between terminal devices such as a mobile phone and a computer, if a computer needs to browse a media file in the mobile phone, the mobile phone needs to generate a thumbnail of the media file and send the thumbnail to the computer, and the computer can only display the thumbnail. Moreover, each time the mobile phone is connected with the computer, the mobile phone needs to regenerate the thumbnail of the media file and send the thumbnail to the computer, and the computer can display the thumbnail, so that when the computer is connected with the mobile phone, the thumbnail is displayed at a low speed, and the thumbnail display efficiency is low.
In the embodiment of the application, a thumbnail obtaining request of a first storage path carrying a media file is sent to a second terminal through a first terminal, so that the second terminal can obtain thumbnail information corresponding to the media file stored in the first storage path according to the thumbnail obtaining request and send a thumbnail obtaining instruction carrying the thumbnail information to the first terminal, and then the first terminal obtains the thumbnail of the media file from a cloud server according to the thumbnail information carried in the thumbnail obtaining instruction and displays the thumbnail; that is, the thumbnail is stored in the cloud server in advance, and is not generated again by the second terminal each time the first terminal and the second terminal are communicatively connected. The second terminal only needs to generate the thumbnail corresponding to the media file when the thumbnail is pre-stored in the cloud server. When the thumbnail needs to be displayed by the first terminal, the thumbnail of the first storage path carrying the media file only needs to be sent to the second terminal, and then the thumbnail obtaining instruction carrying the thumbnail information sent by the second terminal is received, so that the thumbnail of the pre-stored media file can be obtained from the cloud server and displayed, when the second terminal is in communication connection with the first terminal, the thumbnail does not need to be generated again, the step of regenerating the thumbnail by the second terminal is saved, and the display efficiency of the thumbnail is improved.
For example, the first terminal may be a terminal device such as a desktop computer, a notebook computer, and the like, and the second terminal may be a terminal device such as a smart phone, a tablet computer, a digital camera, a walkman, a wearable device, and the like.
Fig. 1 shows a first implementation flowchart of a thumbnail display method provided in an embodiment of the present application, which is applied to a second terminal, and can be executed by a thumbnail display apparatus configured on the second terminal, and is suitable for a situation where the thumbnail display efficiency needs to be improved, and includes steps 101 to 103.
The first terminal and the second terminal work in a command-response mode, that is, the initiating terminal device (the first terminal) sends a command to the responding terminal device (the second terminal) for processing, and the second terminal feeds back a processing result. Therefore, the first terminal needs to send a thumbnail acquiring request carrying the first storage path of the media file to the second terminal first, so that the second terminal can know the media file to be browsed by the first terminal and the storage location of the media file.
It should be noted that the media files may include picture files and video files.
For example, when a user connects a mobile phone to a computer and opens an album in the mobile phone through the computer, the media file is the album file, and the thumbnail to be displayed at the computer end is the thumbnail corresponding to each photo in the album file. If a user opens a video file in a mobile phone through a computer, the thumbnail required to be displayed by the computer end is the thumbnail corresponding to the cover picture of each video in the video file because each video in each video file has one cover picture.
And step 102, acquiring thumbnail information corresponding to the media file stored in the first storage path according to the thumbnail acquisition request.
After receiving a thumbnail acquiring request carrying a first storage path of a media file sent by a first terminal, a second terminal needs to acquire thumbnail information corresponding to the media file stored in the first storage path according to the thumbnail acquiring request.
The thumbnail information corresponding to the media file may include identification information of a thumbnail corresponding to the media file and storage location information of the thumbnail in the cloud server.
103, sending a thumbnail obtaining instruction carrying the thumbnail information to the first terminal; the thumbnail acquiring instruction is used for instructing the first terminal to acquire a thumbnail of the pre-stored media file from a cloud server according to the thumbnail information and display the thumbnail.
After the thumbnail information corresponding to the media file stored in the first storage path is acquired by the second terminal, the thumbnail acquisition instruction carrying the thumbnail information is sent to the first terminal, and at this time, the first terminal can acquire the thumbnail of the pre-stored media file from the cloud server according to the thumbnail information in the thumbnail acquisition instruction and display the thumbnail.
In the embodiment of the application, the thumbnail is pre-stored in the cloud server, but not generated by the second terminal in real time, and when the thumbnail needs to be displayed by the first terminal, the thumbnail of the pre-stored media file can be obtained from the cloud server and displayed by only sending a thumbnail obtaining request carrying a first storage path of the media file to the second terminal and receiving a thumbnail obtaining instruction carrying the thumbnail information sent by the second terminal, so that the step of regenerating the thumbnail is saved, and the display efficiency of the thumbnail is improved.
In some embodiments of the present application, before step 102, the method further comprises: pre-storing the thumbnail information; the thumbnail information includes a first correspondence table between the identification information of the thumbnail and second storage path information of the thumbnail in the cloud server.
That is, before the second terminal acquires the thumbnail information corresponding to the media file stored in the first storage path according to the thumbnail acquisition request sent by the first terminal, the thumbnail information needs to be stored in the second terminal in advance, and the thumbnail information includes a first correspondence table between the identification information of the thumbnail and the second storage path information of the thumbnail in the cloud server.
For example, as shown in fig. 2, the pre-storing of the thumbnail information includes: step 201 to step 203.
Step 201, analyzing each media file stored in the first storage path in advance, generating a thumbnail of each media file, and identifying the thumbnail by using the identification information of each media file.
In the embodiment of the present application, the second terminal may store the thumbnail information of the media file in each storage path in advance, and for convenience of description, only how to store the thumbnail information corresponding to the media file stored in the first storage path in advance is described herein.
When the thumbnail information corresponding to the media files stored in the first storage path is stored in advance, first, each media file stored in the first storage path is analyzed in advance to generate a thumbnail of each media file, and the thumbnail is identified by using the identification information of each media file. In the embodiment of the application, the thumbnails and the media files corresponding to the thumbnails are enabled to be identical in identification information, so that the thumbnails and the media files are in one-to-one correspondence, and the thumbnails corresponding to the media files can be determined according to the identification information by obtaining the identification information of the media files.
Optionally, the analyzing each media file stored in the first storage path in advance to generate a thumbnail of each media file includes: traversing each picture stored in the first storage path in advance to obtain a storage space occupied by each picture; analyzing the picture with the occupied storage space larger than the preset threshold value to generate a corresponding thumbnail, and taking the original picture of the picture with the occupied storage space smaller than or equal to the preset threshold value as the thumbnail corresponding to the picture.
For example, if the preset threshold is 20 bytes, when each picture stored in the first storage path is traversed in advance, analyzing the picture whose occupied storage space is greater than 20 bytes to generate a corresponding thumbnail, and using an original image of the picture whose occupied storage space is less than or equal to 20 bytes as the thumbnail corresponding to the picture; that is, pictures having a storage space of less than or equal to 20 bytes are not parsed.
When the storage space occupied by the picture is less than or equal to the preset threshold, the picture is represented to belong to the small picture, and the loading speed of the picture is not influenced, so that the picture does not need to be analyzed into the thumbnail. In the embodiment of the application, the pictures which do not need to be analyzed and the pictures which need to be analyzed are screened out, so that only the pictures which need to be analyzed are analyzed, the data processing amount of the pictures which do not need to be analyzed is saved, and the thumbnail generation efficiency is improved.
Step 202, storing the thumbnail with the identification information in a cloud server, and acquiring second storage path information of the thumbnail in the cloud server.
Optionally, on the basis of the embodiment described in fig. 2, as shown in fig. 3, the step 102, obtaining, according to the thumbnail obtaining request, thumbnail information corresponding to the media file stored in the first storage path, may further include: step 301 to step 304.
And step 304, deleting the identification information corresponding to the deleted media file from the first corresponding relation table to obtain a second corresponding relation table, and obtaining the thumbnail information carrying the second corresponding relation table.
Since the media files currently stored in the first storage path of the second terminal may have some deleted media files and some media files are newly added media files when the second terminal previously analyzes each media file stored in the first storage path in step 201, when the thumbnail acquisition request is acquired, it is necessary to acquire the identification information of each media file currently stored in the first storage path according to the thumbnail acquisition request, so as to mark the media file corresponding to the identification information that fails to match the identification information of each media file currently stored in the first storage path in the first correspondence table as deleted media file in the first storage path by matching the identification information of the thumbnail in the first correspondence table with the identification information of each media file currently stored in the first storage path A media file to be deleted; and simultaneously, deleting the identification information corresponding to the deleted media file from the first corresponding relation table to obtain a second corresponding relation table, and obtaining the thumbnail information carrying the second corresponding relation table.
Specifically, in practical applications, the identification information corresponding to the deleted media file is deleted from the first correspondence table, and the second storage path information of the thumbnail corresponding to the deleted media file in the cloud server is also deleted.
That is, the thumbnail information carrying the second correspondence table sent to the first terminal is the correspondence table generated according to the media file currently and actually stored in the first storage path.
For example, the first correspondence table is a correspondence table as shown in table one, that is, the media files stored in the first storage path when the second terminal previously analyzes each media file stored in the first storage path in step 201 include: media files with information 1101, 1102, 1103, and 1104 are identified. If the identification information obtained when the identification information of each media file currently stored in the first storage path is obtained according to the thumbnail obtaining request in step 301 is 1101, 1102, 1104, 1105 and 1106, it indicates that the media file with the identification information 1103 has been deleted from the first storage path, so that it is necessary to delete the identification information 1103 and the second storage path C of the thumbnail corresponding to the identification information 1103 of the thumbnail in the first correspondence table as shown in table one, thereby obtaining a second correspondence table as shown in table two.
Table one:
| identification information | Second storage path information |
| 1101 | A |
| 1102 | B |
| 1103 | C |
| 1104 | D |
Table two:
| identification information | Second storage path information |
| 1101 | A |
| 1102 | B |
| 1104 | D |
Optionally, as shown in fig. 4, after the step 302 matches the identification information of the thumbnail in the first mapping table with the identification information of each media file currently stored in the first storage path, the method further includes: step 305 to step 307.
In this embodiment of the application, since the newly added media files in the first storage path are not pre-stored in the cloud server, it is necessary to mark, by the second terminal, the media file corresponding to the identification information of which matching with each identification information of the first correspondence table fails, in the identification information of the media files currently stored in the first storage path, as the newly added media file in the first storage path, and then, the second terminal analyzes the newly added media file in the first storage path, generates a thumbnail corresponding to the newly added media file, and then sends the thumbnail to the first terminal for display.
Optionally, after the second terminal parses the newly added media file in the first storage path to generate a thumbnail corresponding to the newly added media file, the thumbnail may be stored in the cloud server, second storage path information of the thumbnail in the cloud server is acquired, and then the second correspondence table is updated to obtain an updated third correspondence table, so that when the first terminal is connected with the second terminal next time, the second terminal may generate new thumbnail information based on the third correspondence table.
In the embodiment described in fig. 3 and 4, the second terminal may not execute step 302, match the identification information of the thumbnails in the first correspondence table with the identification information of each media file currently stored in the first storage path, instead, after the first terminal first obtains a thumbnail corresponding to the identification information of each media file currently stored in the first storage path from the cloud server, mark the media file corresponding to the thumbnail that is not obtained from the cloud server as a newly added media file in the first storage path, and send the identification information corresponding to the newly added media file to the second terminal; and the second terminal sends the thumbnail corresponding to the newly added media file to the first terminal according to the identification information corresponding to the newly added media file.
Optionally, on the basis of the embodiment shown in fig. 2, as shown in fig. 5, in step 102, acquiring, according to the thumbnail acquisition request, thumbnail information corresponding to the media file stored in the first storage path, further includes: step 501 to step 502.
That is, the thumbnail information includes identification information of each media file currently stored in the first storage path and the first correspondence table, instead of the second correspondence table.
Optionally, after the step 103 sends the thumbnail obtaining instruction carrying the thumbnail information to the first terminal, the method includes: and acquiring identification information corresponding to the newly added media file in the first storage path returned by the first terminal, analyzing the newly added media file in the first storage path according to the identification information corresponding to the newly added media file, generating a thumbnail corresponding to the newly added media file, sending the thumbnail corresponding to the newly added media file to the first terminal, and displaying the thumbnail by the first terminal.
That is to say, after the second terminal generates a thumbnail obtaining instruction carrying the identification information of each media file currently stored in the first storage path and the thumbnail information of the first corresponding relationship table and sends the thumbnail obtaining instruction to the first terminal, the first terminal obtains a thumbnail corresponding to the identification information of each media file currently stored in the first storage path from the cloud server according to the thumbnail information carried in the thumbnail obtaining instruction; simultaneously marking the media files corresponding to the identification information which does not acquire the thumbnail from the cloud server as the newly added media files in the first storage path, and sending the identification information corresponding to the newly added media files to the second terminal; and the second terminal acquires identification information corresponding to the newly added media file in the first storage path returned by the first terminal, analyzes the newly added media file in the first storage path according to the identification information corresponding to the newly added media file, generates a thumbnail corresponding to the newly added media file, sends the thumbnail corresponding to the newly added media file to the first terminal, and displays the thumbnail by the first terminal.
As shown in fig. 6, a second implementation flow diagram of a thumbnail display method provided in the embodiment of the present application is applied to a first terminal, and the method can be executed by a thumbnail display device configured on the first terminal, and is suitable for a situation where the thumbnail display efficiency needs to be improved, and includes steps 601 to 603.
Step 603, obtaining a pre-stored thumbnail of the media file from the cloud server according to the thumbnail obtaining instruction, and displaying the thumbnail.
Optionally, in step 603, acquiring the thumbnail of the media file from the cloud server according to the thumbnail acquisition instruction may include: acquiring a thumbnail of the media file from a cloud server according to thumbnail information including a second corresponding relation table carried in the thumbnail acquiring instruction, and receiving a thumbnail corresponding to a newly added media file sent by the second terminal; the second correspondence table is obtained by deleting the identification information corresponding to the deleted media file from the first correspondence table between the identification information of the thumbnail pre-stored by the second terminal and the second storage path information of the thumbnail in the cloud server.
Optionally, as shown in fig. 7, the step 603, according to the thumbnail obtaining instruction, obtaining the thumbnail of the media file from the cloud server, may further include: step 701 to step 703.
It should be noted that, for convenience and brevity of description, the specific working process of the thumbnail display method described in fig. 6 and fig. 7 may refer to the corresponding process of the method described in fig. 1 to fig. 5, and is not described again here.
