Abstract
The invention discloses a method for converting video into character animation under a Spring boot frame, which comprises the following steps: step 1: acquiring a video File from a front-end page and transmitting the video File to a back end, reading video content after receiving the video File by the back end, converting the File received by the back end into a File type and then writing the File type into a byte stream; step 2: segmenting the byte stream, writing the segmented byte stream into File objects, and then converting each File object into a corresponding picture stream; and step 3: graying the picture stream, filling the picture stream with the character string, returning the filled character string to the front end for display, and setting a frame time interval at the front end to maintain the number of playing frames per second of the original video.
Description
Technical Field
The invention relates to the field of computer video processing, in particular to a method for converting video into character animation under a Spring boot frame.
Background
The invention aims to solve the problem that no method for quickly and conveniently converting video into character animation exists in the current JAVA EE development. The reason for this problem is that the processing support of JAVA to video is not perfect, so most solutions to this problem are implemented by python, and JAVA implementation solutions are few. If JAVA is used for processing, external software is required to capture each frame and then code each frame for processing. Therefore, when a person engaged in JAVA development needs to complete a task of converting a video into a character animation under a spring boot frame, the code amount is very large and the degree of reduction of the character animation is not high enough.
Disclosure of Invention
The invention aims to provide a method for converting a video into a character animation under a Spring boot frame, which is used for solving the problems that in the prior art, when a JAVA developer needs to complete a task of converting the video into the character animation under the Spring boot frame, the code amount is extremely large and the reduction degree of the character animation is not high enough.
The invention solves the problems through the following technical scheme:
a method of animating video to characters under a Spring boot frame, the method comprising the steps of:
step 1: acquiring a video File from a front-end page and transmitting the video File to a back end, reading video content after receiving the video File by the back end, converting the File received by the back end into a File type and then writing the File type into a byte stream;
step 2: segmenting the byte stream, writing the segmented byte stream into File objects, and then converting each File object into a corresponding picture stream;
and step 3: graying the picture stream, filling the picture stream with the character string, returning the filled character string to the front end for display, and setting a frame time interval at the front end to maintain the number of playing frames per second of the original video.
Preferably, in step 1, MultipartFile reception is adopted when the video file is received at the back end.
Preferably, in the step 3, the picture stream is grayed by using buffer image.
Preferably, when filling the picture stream in step 3, the color of each pixel point is determined first, and the color is close to black filled characters and close to white filled spaces.
Preferably, in step 3, when the front end is returned, the populated character string is returned in JSON format by using ResponseBody of the Spring boot frame.
Preferably, when the picture stream is divided in step 2, the picture stream is divided according to a fixed size.
Compared with the prior art, the invention has the following advantages and beneficial effects:
the invention provides a method for converting video into character animation based on JAVA under a spring boot frame.
Drawings
FIG. 1 is a schematic block diagram of the process of converting video into character animation according to the present invention.
Detailed Description
The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.
Example 1:
referring to fig. 1, a method for animation of video to character under Spring boot frame, first, the video is transmitted from the front end to the back end. The front end adopts a form submission mode, and the mp4 video file is packaged into the form and submitted to the background. The background receives the corresponding file passed to the background with the MultipartFile class. The multipartFile class is a type of a corresponding file provided by the spring boot framework, and is convenient for file transmission between the foreground and the background. The form is a basic component of the front-end page, and various files and data can be placed in the form so as to be submitted to the background.
And then converting the MultiFile into a File class, writing the File class into the byte stream, and after the writing is finished, storing the information of the File in the byte stream so as to facilitate the subsequent processing of the video File by the JAVA code. The File class is a class corresponding to files (such as mp3, mp4, excel) in a computer carried by JAVA itself, and the files can be indirectly operated by the File class. The byte stream is also a file operation medium in JAVA, and can be used for more detailed processing of files.
And segmenting the obtained byte stream, and rewriting the segmented byte stream into the File class.
After the picture stream is obtained again, the construction attribute is specified to be buffer image. The picture stream is a kind of corresponding picture file in JAVA, and the picture stream can be used to indirectly manipulate the picture, such as viewing picture information, etc. The buffer image, type, byte, gray attribute function is to create a picture stream of a corresponding picture file in a graying manner. Thus, a grayed picture can be obtained.
And then performing character filling on the grayed picture. And circularly traversing each pixel point of the picture, judging whether the point is close to black or white according to the rgb value of each pixel point, filling the point close to black with special characters, and filling the point close to white with blank spaces. RGB is an internationally common color standard. The picture stream contains information of pixel points of the picture, through which the rgb value of the pixel point can be obtained, and then the rgb value is further judged to be close to black or white.
After completion of the padding, the padded character string structure is returned to the front end in json by ResponseBody of spring boot. And after receiving json, the front end takes the character string array contained in the json, sets the playing time interval of each character string in the character string array, and locally refreshes and displays on the page, so that the character animation can be displayed. Wherein, ResponseBody is an annotation in the spring boot frame, and the function is to return the returned result in JSON format.
Although the present invention has been described herein with reference to the illustrated embodiments thereof, which are intended to be preferred embodiments of the present invention, it is to be understood that the invention is not limited thereto, and that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure.
