It should be understood that the number of upload terminals, servers, download terminals in fig. 1 is merely illustrative. Any number of uploading terminals, servers, downloading terminals may be present, as desired.
With continued reference to fig. 2, a flow 200 of one embodiment of a method for video cover storage parsing according to the present application is shown as applied to a download terminal. The method for storing and analyzing the video cover comprises the following steps:
In this embodiment, an executing body (e.g., the download terminal 103 shown in fig. 1) of the method for video cover storage parsing may send a download request including an object file identifier to a server. And the server sends the target file corresponding to the target file identifier to the downloading terminal.
In this embodiment, after receiving the target file, the downloading terminal parses the tag from the target file according to a predetermined format. The label may or may not be a filtered cover image.
Optionally, if the downloading terminal does not support parsing out the tag, the target file is directly decoded in a conventional manner, and a video can also be obtained.
In this embodiment, if the label is filtering, it indicates that the target file includes a second encoding block encoded by an independent video encoding storage space in addition to the first encoding block obtained by the original video encoding. The second coding block comprises a cover image, a residual image and a position mapping relation of the cover image in the video. The generation process of the first encoding block and the second encoding block is shown in step 402 and 404.
And step 204, decoding the first coding block to obtain a video.
In this embodiment, decoding is performed by using a decoding method corresponding to the encoding method. The encoding mode of the uploaded file and the decoding mode of the downloaded file can be specified by the video website.
And step 205, decoding the second coding block to obtain the position mapping relation of the residual image, the cover image and the cover image in the video.
In this embodiment, this step is the reverse of step 404.
In some optional implementations of this embodiment, the second encoded block is decrypted and then decoded. The decryption method can be predetermined.
And step 206, replacing the video frame corresponding to the position mapping relation in the video with the residual image.
In the present embodiment, a cover image in the original video is replaced with a residual image to generate a new video. The new video may be linked to the cover image and the cover image displayed. If the user clicks the cover image, a new video is played, and the cover image is not displayed at the first frame or the last frame.
And step 207, if the label is not filtered, analyzing the third coding block from the target file.
In this embodiment, if the parsed label is not filtered, the second encoded block encoded by the independent video encoding storage space in the target file only includes the original video.
And step 208, decoding the third coding block to obtain a video and a cover image.
In this embodiment, this step is the reverse of step 407. The cover image is located at the first or last frame of the video.
With continued reference to fig. 3, a flow 300 of one embodiment of a method for video cover storage resolution in accordance with the present application as applied to a server is shown. The method for storing and analyzing the video cover comprises the following steps:
In the present embodiment, an execution subject (e.g., the server 102 shown in fig. 1) of the method for video cover storage parsing may receive an upload file from an upload terminal. The server can analyze each parameter according to the data packet format. The upload file may include the address and tag of the cover image of the video.
In the embodiment, the cover image is downloaded according to the address of the cover image of the video and displayed to other terminals for browsing. The cover image is not required to be decoded from the video, so that the pressure of the server can be relieved.
And step 303, storing other data except the address in the uploading file as a downloading file in the video list.
In this embodiment, there are different encoding blocks according to the label. If the label is filtering, the other data except the address in the uploaded file comprises a first coding block, a second coding block and a label, wherein the first coding block is obtained by coding the video, the second coding block is obtained by coding a cover image, a residual image of the cover image and a position mapping relation of the cover image in the video, and the label is used for indicating whether the cover image is filtered or not.
If the tag is filtering, the other data in the uploaded file except the address comprises: the third coding block is obtained by coding the cover image before splicing the first frame or after splicing the first frame of the video together with the label, and the label is used for indicating whether the cover image is filtered or not.
Optionally, the third encoded block may also be encrypted. The other data in the upload file other than the address includes: the video coding method comprises a first coding block, an encrypted coding block and a label, wherein the first coding block is obtained by encoding a video, the encrypted coding block is obtained by encoding a residual image of a cover image and the cover image and a position mapping relation of the cover image in the video and then encrypting the encoded residual image and the cover image, and the label is used for indicating whether the cover image is filtered or not.
In some optional implementations of this embodiment, in response to receiving the author ID, the upload file is saved to a video list corresponding to the author ID. And the video is stored according to the author ID, so that the user can conveniently inquire and download.
In this embodiment, the downloading terminal may send a downloading request including the target file identifier to the server. And the server sends the target file corresponding to the target file identifier to the downloading terminal. Decoding is performed by the download terminal.
With continuing reference to fig. 4, a flow 400 of one embodiment of a method for video cover storage resolution in accordance with the present application as applied to an uploading terminal is shown. The method for storing and analyzing the video cover comprises the following steps:
in response to detecting an author's selection of a cover image of a video, the author is asked whether to filter the cover image, step 401.
In the present embodiment, the author needs to select a cover image when uploading a video using an execution body (e.g., the uploading terminal 101 shown in fig. 1) of the method for video cover storage parsing. The author may select a certain frame in the video as the cover image. The uploading terminal can also recommend the cover image through a preset algorithm, and then the author selects and confirms the cover image. When the upload terminal detects an operation of the author selecting the cover image of the video, the author is asked through voice or a dialog box whether to filter the cover image. If the author chooses to filter the cover image, the video-related data is encoded in a manner different from conventional encoding.
If the author chooses to filter the cover image, the labels of the video are set to filter, and a residual image is generated based on the cover image, step 402.
In this embodiment, the video has a tag for identifying whether to filter the cover image, and if the user selects to filter the cover image, the tag may be set to 1. If the cover image is selected to be unfiltered, the tag may be set to 0. Therefore, the terminal downloading the video can select a corresponding decoding mode according to the label.
The residual image can be obtained by a residual image method. A residual image method (residual), i.e., adjusting each pixel value in the original image according to a certain rule, such as using a geometric mean value of a spectral vector to perform normalization processing on image data to obtain a relative reflectivity; or selecting the maximum value of each wave band (representing the measured value of 100 reflections) in the whole image, and subtracting the normalized average radiation value of the maximum value of each wave band. For example, the original cover image may be subjected to a transparency process to obtain a residual image.
And 403, putting the residual image and the cover image into independent video coding storage spaces, and identifying the position mapping relation of the cover image in the video coding storage spaces.
In this embodiment, the residual image and the cover image need to be encoded in separate video encoding storage spaces, and no longer occupy the video encoding storage space of the original video. Because the residual image is based on the cover image in the original video, the positional mapping of the cover image in the video, e.g., frame 1003, can be identified when the author selects the cover image.
And step 404, coding the video to obtain a first coding block, and coding the data in the video coding storage space to obtain a second coding block.
In this embodiment, the video encoding method is a method of converting a file in an original video format into a file in another video format by a compression technique. The most important codec standards in video streaming include h.261, h.263, and h.264 of the international telecommunication union, M-JPEG of the moving picture experts group, and MPEG series standards of the moving picture experts group of the international organization for standardization, and also RealVideo of Real-Networks, WMV of microsoft, QuickTime of Apple, and the like, which are widely used on the internet. And generating a first coding block and a second coding block by adopting the same coding mode. The data in the video coding storage space comprises a residual image, a cover image and a position mapping relation.
And 405, packaging the addresses of the first coding block, the second coding block, the label and the cover image into an uploading file and uploading the uploading file to a server.
In this embodiment, since the cover image needs to be displayed on the server, in order to save the encoding and decoding overhead, the address of the cover image is directly sent to the server. And the server downloads the data automatically. The cover image may also be uploaded directly to the server. When the data packet is packed and uploaded, information such as length indication can be added to the packet header of the data packet to indicate the length of the first coding block and the length of the second coding block. The header may also include some field identification such as the start location and length of the author ID, profile, etc. information. And the download terminal is used for indicating the download terminal to analyze.
In some optional implementations of the present embodiment, the author ID may also be appended to the video uploaded by the author. The server can store the video according to the author ID, and a user can search the video according to the author ID conveniently.
In some optional implementations of this embodiment, the second encoding block may be encrypted and then the encoding block may be encrypted. And then the addresses of the first coding block, the encrypted coding block, the label and the cover image are packaged into an uploading file and uploaded to a server. The encryption mode can be encrypted by adopting a video encryption technology common in the prior art. The information can be ensured to be safe through encryption.
At step 406, if the author chooses not to filter the cover image, the tag of the video is set to no filtering.
In this embodiment, if the author chooses not to filter the cover image, the tag of the video is set to unfiltered and the download side can decode in a conventional manner. Therefore, the player which does not support the filtering mode can be compatible.
In this embodiment, if the author chooses not to filter the cover image, then there is no need for a separate video coding storage space for the cover image. The cover image is spliced to the front frame or the rear frame of the video and then coded together to generate a third coding block. Whether the frame is placed before the first frame or after the last frame may be predetermined so that the decoding download side can recognize which frame is the cover image.
And step 408, packaging the addresses of the third coding block, the label and the cover image into an uploading file and uploading the uploading file to the server.
In this embodiment, since the cover image needs to be displayed on the server, in order to save the encoding and decoding overhead, the address of the cover image is directly sent to the server. And the server downloads the data automatically. The cover image may also be uploaded directly to the server. The author may also attach information such as author ID, video profile, etc. when uploading the video. When the data packet is packed and uploaded, information such as length indication can be added to the packet header of the data packet to indicate the length of the third coding block. The data packet has a predetermined format that specifies which fields the data packet includes, the length of each field, etc.
With continued reference to fig. 5, fig. 5 is a schematic diagram of an application scenario of the method for video cover storage parsing according to the present embodiment. Three-terminal interactions are involved in the application scenario of fig. 5:
1. uploading a terminal: the author first selects the cover image that he wants to set the cover by frame-by-frame filtering. The author clicks to determine whether to pop up a dialog box for video playing cover filtering, if the user selects 'yes', the video is labeled to tell the server, and the cover image and the residual image are put into a separate video coding storage space. And identifying the position mapping relation of the cover image in the original video in space. And encoding the original video to generate a first encoding block, and encoding data in the video encoding storage space to obtain a second encoding block.
2. A server: and storing the code files uploaded by each author, and sending the code files to each downloading terminal when receiving a downloading request.
3|, downloading the terminal: and when the user selects video downloading and clicks the video to play, firstly judging the label issued by the server, and if the label indicates that the cover image filtering is required, transmitting the data of the specific independent storage area into a decoder for decoding. And replacing the video frame corresponding to the position mapping relation in the video by the residual image, linking the cover image to the video, and displaying the cover image.
Compared with the current processing mode in the industry, the method provided by the embodiment of the application has the greatest advantage of realizing an effective and feasible image frame filtering processing mode on the basis of resource saving and time-saving intelligence. The image storage is carried out through the independent video storage area, and the image is filtered according to the requirements of the user.
