[0047] In an optional embodiment, obtaining audio stream data includes: displaying an audio list in a visual interface, and in response to an audio selection operation on the audio list, using the selected reference audio corresponding to the audio selection operation as the audio stream data. Specifically, the audio list includes at least one reference audio.

[0054] This embodiment does not limit the method for obtaining the audio stream data and the to-be-processed picture based on the picture protocol format, and the specific settings can be customized according to actual needs.

[0055] S120: Perform a data encapsulation operation on the image to be processed and the audio stream data to generate a target image based on the image protocol format.

[0056] In this embodiment, the first data block in the target image stores the protocol data in the first data block in the image to be processed, and the second data block in the target image stores the audio protocol data corresponding to the audio stream data obtained by the data encapsulation operation, and the first data block and the second data block are both data blocks specified in the image protocol format.

[0057] Specifically, in the definition of the picture protocol format, the first data block is used to store protocol data directly related to the image information, and the second data block is used to store protocol data not directly related to the image information, such as remark information, copyright information or blank fields, etc. In this embodiment, the second data block is used to represent an uncommon data block or an unimportant data block in the picture protocol format. Specifically, the first data block in the target picture is a data block other than the second data block.

[0058] In an optional embodiment, when the picture protocol format is a Graphics Interchange Format (GIF), the second data block is an application extension block or an annotation extension block in the Graphics Interchange Format (GIF).

[0059] Specifically, the Graphic Interchange Format (GIF) stores image information in the form of data blocks. According to the characteristics of different data blocks, each data block can be divided into three categories, namely, control block, image description block and special purpose block. Among them, the control block is used to control the processing of image data stream and the setting of hardware parameters. Specifically, the control block contains a file header, a logical screen description block, a graphic control extension block and a file trailing block; the image description block is used to describe the display information required for the image on the display device. Specifically, the image description block contains an image identifier block (Image Descriptor), a global color index table (Global Color Table), a local color index table (Local Color Table), image compression data (ImageData) and an image text extension block (Plain Text Extension). The special purpose block is used to represent information that is not directly related to the image information of the GIF image. Specifically, the special purpose block contains an application extension block (Application Extension) and a comment extension block (Comment Extension).

[0060] Specifically, the application extension block is used to make information related to the application, including a block start code 0x21FF, an application identification code, an application data sub-block, and a block end code 0x00, etc. The comment extension block can be used to store any non-graphic data such as copyright and author, including a block start code 0x21FE, multiple sequence data sub-blocks, and a block end code 0x00. The sequence data sub-block can store up to 255 bytes.

[0061] Figure 2 A schematic diagram of a graphic exchange format provided by an embodiment of the present invention. Specifically, Figure 2The dashed box indicates that the data block is optional, and the solid box indicates that the data block is mandatory. There is at least one global color index table and local color index table in the Graphics Interchange Format GIF. When both global color index table and local color index table exist in the Graphics Interchange Format GIF, the local color index table is used. The scope of the file header, logical screen description block and global color index table is the entire data domain.

[0062] In another optional embodiment, when the image protocol format is the standard image format BMP, the second data block is a color palette block in the standard image format BMP; when the image protocol format is the Joint Photographic Experts Group JPEG or the Exchangeable Image File Format Exif, the second data block is a data block between the character strings 0xFFE0-0xFFEF in JPEG or Exif.

[0063] In an optional embodiment, the data encapsulation operation is performed on the picture to be processed and the audio stream data to generate a target picture based on the picture protocol format, including: obtaining the protocol data in the second data block in the picture to be processed, and deleting the protocol data from the picture to be processed to obtain an intermediate picture; generating audio protocol data corresponding to the second data block according to the audio stream data; and writing the audio protocol data into the second data block in the intermediate picture to obtain a target picture.

[0064] Specifically, in the process of performing a data reading operation on the image to be processed, when a block start character corresponding to the second data block is read, all protocol data from the block start character to the block end character of the second data block are used as protocol data in the second data block. The block start character and the block end character are used to mark the data block position of the second data block.

[0065] Specifically, the block start character and block end character can be used to represent a specific identifier, and can also be used to represent the starting byte number and the ending byte number corresponding to the data block, wherein the difference in bytes between the starting byte number and the ending byte number represents the block field length corresponding to the data block.

[0066] In an optional embodiment, audio protocol data corresponding to the second data block is generated according to the audio stream data, including: when a block start code and a block end code are used to represent a specific identifier, the block start code corresponding to the second data block, the audio stream data and the block end code corresponding to the second data block are written in sequence into the audio protocol data corresponding to the second data block, or the audio data length of the audio stream data is obtained; the block start code corresponding to the second data block, the audio data length, the audio data stream and the block end code corresponding to the second data block are written in sequence into the audio protocol data corresponding to the second data block.

[0067] In another optional embodiment, audio protocol data corresponding to the second data block is generated based on the audio stream data, including: when a block start character and a block end character are used to represent the starting byte number and the ending byte number, the audio stream data is written into the audio protocol data corresponding to the second data block, or the audio data length of the audio stream data is obtained, and the audio data length and the audio data stream are written into the audio protocol data corresponding to the second data block.

[0068] The technical solution of this embodiment obtains audio stream data and a to-be-processed picture based on a picture protocol format, performs a data encapsulation operation on the to-be-processed picture and the audio stream data, and generates a target picture based on a picture protocol format, wherein the first data block in the target picture stores the protocol data in the first data block in the to-be-processed picture, and the second data block in the target picture stores the audio protocol data corresponding to the audio stream data obtained by the data encapsulation operation, and the first data block and the second data block are both data blocks specified in the picture protocol format, which solves the problem that the picture protocol format cannot store audio information, enriches the dissemination content of the picture, and improves the dissemination effect of the picture.

This embodiment further refines the "performing a data encapsulation operation on the image to be processed and the audio stream data to generate a target image based on the image protocol format" in the above embodiment. Figure 3 As shown, the method includes:

[0070] S210: Acquire audio stream data and a to-be-processed picture based on a picture protocol format.

[0071] S210 in this embodiment is similar to that in the above embodiment. Figure 1 The S110 shown corresponds to the same or similar steps, and will not be described in detail in this embodiment.

[0072] S220: Write protocol data in at least one first data block located before the second data block in the picture to be processed into the target picture in sequence.

[0073] Specifically, in the process of performing a data reading operation on the to-be-processed picture, before a block start character corresponding to a second data block is read, protocol data in at least one first data block is sequentially written into the target picture.

[0076] In another optional embodiment, in an optional embodiment, audio protocol data corresponding to the second data block is generated according to the audio stream data, including: when a block start character and a block end character are used to represent the starting byte number and the ending byte number, the audio stream data is written into the audio protocol data corresponding to the second data block, or the audio data length of the audio stream data is obtained, and the audio data length and the audio data stream are written into the audio protocol data corresponding to the second data block.

[0077] In another optional embodiment, generating audio protocol data corresponding to the second data block based on the audio stream data includes: according to a preset readable length, cyclically reading audio segment data in the audio stream data in sequence; if the segment data length of the audio segment data is equal to the preset readable length, writing the preset readable length and the audio segment data corresponding to the audio protocol data corresponding to the second data block; if the segment data length is less than the preset readable length, writing the segment data length and the audio segment data corresponding to the audio protocol data.

[0078] Specifically, the preset readable length can be used to represent the unit storable length corresponding to the second data block, and can also be used to represent the single readable length of the audio reader. Exemplarily, the preset readable length can be 255 bytes, and the preset readable length is not limited here.

[0079] Specifically, the segment data length is used to represent the data length of the audio segment data, and the segment data length is less than or equal to the preset readable length. The advantage of such a setting is that the audio decoding efficiency of the audio protocol data in the subsequent picture playback process can be improved.

[0080] In an optional embodiment, generating audio protocol data corresponding to the second data block based on the audio stream data further includes: when a block start code and a block end code can be used to represent a specific identifier, before cyclically reading the audio segment data in the audio stream data in sequence according to a preset readable length, writing the block start code corresponding to the second data block into the audio protocol data, and after writing the last audio segment data into the audio protocol data, writing the block end code corresponding to the second data block into the audio protocol data.

[0082] Based on the above embodiment, optionally, before cyclically reading the audio segment data in the audio stream data in sequence according to a preset readable length, the method further includes: performing a data encryption operation on the audio stream data to obtain encrypted audio stream data, and using the encrypted audio stream data as the current audio stream data.

[0083] Exemplarily, the encryption algorithms used in data encryption operations include, but are not limited to, the Data Encryption Standard algorithm (DES), the International Data Encryption Algorithm (IDEA), the RSA algorithm, the Digital Signature Algorithm (DSA), and the Advanced Encryption Standard algorithm, etc. The encryption algorithms used are not limited here and can be customized according to actual needs.

[0084] The advantage of this setting is that it can improve the security of audio stream data.

[0085] S240: Write the protocol data in at least one first data block located after the second data block in the picture to be processed into the target picture in sequence.

[0086] Specifically, in the process of performing a data reading operation on the to-be-processed picture, after a block terminator corresponding to the second data block is read, the protocol data in the at least one first data block is sequentially written into the target picture.

[0087] The technical solution of this embodiment solves the data encapsulation problem of the target picture by sequentially writing the protocol data in at least one first data block before the second data block in the picture to be processed into the target picture, generating audio protocol data corresponding to the second data block according to the audio stream data, and writing the audio protocol data into the target picture, and sequentially writing the protocol data in at least one first data block after the second data block in the picture to be processed into the target picture, thereby improving the stability of generating the target picture and the accuracy of the target picture.

According to the segment data length, the audio segment data in the audio protocol data is read, and the byte data read after the audio segment data is used as the segment data length, and the step of reading the audio segment data in the audio protocol data according to the segment data length is repeated until the byte data after the audio segment data is the block terminator of the second data block, or the byte number corresponding to the last audio byte in the audio segment data is the ending byte number corresponding to the second data block, and at least one audio segment data is obtained.

[0111] S440: Generate audio stream data according to at least one audio segment data.

[0112] In an optional embodiment, determining the audio stream data according to at least one audio segment data includes: using the audio data constituted by the at least one audio segment data as the audio stream data.

[0113] In another optional embodiment, determining the audio stream data based on at least one audio segment data includes: using audio data composed of at least one audio segment data as reference audio data, and performing a data decryption operation on the reference audio data to obtain the audio stream data.

[0114] Exemplarily, the decryption algorithm used in the data decryption operation includes, but is not limited to, the decryption algorithms corresponding to the Data Encryption Standard (DES), the International Data Encryption Algorithm (IDEA), the RSA algorithm, the Digital Signature Algorithm (DSA), and the Advanced Encryption Standard algorithm, etc., and the decryption algorithm used is not limited here, and can be customized according to actual needs. It can be understood that the decryption algorithm used in this embodiment is a decoding algorithm corresponding to the encryption algorithm used in the above-mentioned picture generation algorithm.

[0115] S450: synchronously play the playback picture data and the audio stream data.

[0116] In an optional embodiment, the playback screen data includes a color index table and preview screen data; accordingly, the synchronous playback of the playback screen data and the audio stream data includes: determining the current playback screen frame according to the color index table and the preview screen data, and obtaining the current audio segment in the audio stream data that is time-aligned with the current playback screen frame; and synchronously playing the current playback screen frame and the current audio segment.

[0117] In this embodiment, the image protocol format is the graphic interchange format GIF, and the playback screen data includes a color index table and preview screen data. The color index table is a global color index table or a local color index table, and the preview screen data includes LZW decompressed data corresponding to each playback screen frame. The basic principle of LZW (Lempel-Ziv-Welch Encoding, string table compression algorithm) is to extract different characters from the original text file data, create a compilation table based on these characters, and then use the index of the characters in the compilation table to replace the corresponding characters in the original data, so as to achieve the purpose of reducing the data size of the original text file data.

[0118] The advantage of such a setting is that if the synchronous playback is performed after waiting for the picture decoding operation and the audio decoding operation to be completed, the decoding time of the target picture will be increased, and the playback efficiency of the target picture will be reduced. In this embodiment, by setting the picture decoding operation to the pre-picture decoding operation, only the color index table and the preview picture data are decoded in the picture decoding stage, and in the synchronous playback process, the current playback picture frame is further decoded, and the current playback picture frame is synchronously played with the current audio segment that has been decoded and aligned in time, which solves the problem of time asynchrony caused by the difference in decoding speed between the picture decoding operation and the audio decoding operation, and reduces the decoding time of the target picture and improves the playback efficiency of the target picture while achieving the purpose of synchronous playback of the picture and audio.

[0119] The technical solution of this embodiment obtains audio stream data by performing an audio decoding operation on audio protocol data, including: cyclically reading the segment data length in the audio protocol data in sequence, and reading the audio segment data in the audio protocol data according to the segment data length, and generating audio stream data according to at least one audio segment data, which solves the data decoding problem of the target image and improves the audio decoding efficiency of the audio protocol data.
