Fig. 1 is a schematic diagram of main flow of a video file processing method according to an embodiment of the present application, and as shown in fig. 1, the video file processing method includes:
step S101, in response to receiving a video file uploading request, acquiring real-time hardware resource data, and further executing automatic slicing on the video file according to the real-time hardware resource data to obtain a sliced video file.
In this embodiment, the execution body (for example, may be a server) of the video file processing method may receive the video file upload request through a wired connection or a wireless connection. For example, the video file uploading request may be a request for uploading a consultation video file to a preset terminal by a patient in an online consultation scene of an internet hospital for a doctor to check and reference. Specifically, the inquiry video file that the patient needs to upload may be a large file within a preset threshold range, which may be 0 to 200M. The preset threshold range is not specifically limited in the embodiment of the present application. And triggering and acquiring real-time hardware resource data by the execution main body after receiving the video file uploading request. Specifically, the hardware resource data may include memory remaining capacity data, calculation power data of a central processing unit CPU, and the like, and the content included in the hardware resource data is not specifically limited in the embodiment of the present application. And (3) automatically slicing by integrating the number and the size of the slices carried by the hardware resource data, and ensuring the performance of the hardware to be within a preset range so as to obtain the corresponding sliced video file. The video file to be uploaded can be fragmented into zero to accelerate the file uploading speed.
Step S102, obtaining hash values corresponding to the segmented video files, further executing anti-replay check processes based on the hash values, obtaining anti-replay check result data, further determining corresponding uploading progress display types, executing uploading operation on the segmented video files based on the uploading progress display types, responding to uploading interruption, marking interruption positions and continuing to execute the uploading operation from the interruption positions after interruption is resumed.
Specifically, determining a corresponding uploading progress display type includes: and determining the corresponding uploading progress display type as a direct progress display preset value in response to the fact that the anti-duplicate verification result data corresponds to the same hash value in the hash values corresponding to the segmented video files. For example, the preset value may be 99% or 99.99%, which is not specifically limited in the embodiment of the present application. And when the corresponding uploading progress display type is a direct progress display preset threshold value, skipping uploading, directly performing progress display preset numerical values, and executing and storing thumbnail images so as to accelerate the file uploading rate.
In this embodiment of the present application, the hash value corresponding to each piece of video file may be a hash value calculated by a Message-Digest Algorithm (MD 5), and in this embodiment of the present application, the hash value may be represented by MD5. The execution body may perform a check on whether each of the fragmented video files is duplicated or not, that is, whether there is the same MD5, based on MD5. The resulting anti-replay check result data may include the same MD5 or no same MD5. And determining the uploading progress display type according to the anti-duplicate checking result. For example, when the proof verification result is that the MD5 is the same, the type of the upload progress display of the corresponding segmented video file may be determined as 99% of the direct progress display (here, the specific display content is not specifically limited), and the corresponding segmented video file may be skipped. When the anti-replay check result is that the same MD5 does not exist, displaying according to the actual progress, and uploading the corresponding segmented video file normally, so that the segmented video file can be prevented from being repeatedly uploaded, the simplicity of uploading the segmented video file is ensured, and the situation that the segmented video file is uploaded redundantly is avoided.
And executing uploading operation on each piece of video file based on the uploading progress display type, responding to uploading interruption, marking the interruption position and continuing to execute the uploading operation from the interruption position after the interruption is recovered. The breakpoint continuous transmission is realized, the file uploading efficiency is improved, and the user experience is improved.
Step S103, in response to successful uploading of each piece of video file, merging operation is executed to generate a merged video file, and a video short link corresponding to the merged video file is obtained.
The merging operation may be performed, for example, by adding each successfully uploaded fragmented video file to the same video file, so as to generate a merged video file. For example, the merged video file may display a video file transition marker. The video short links corresponding to the combined video files refer to a network link form, and only one short URL address can be used for quickly transmitting video file data. The short link can more effectively accelerate video file transmission, so that the short link is more commonly used in an Internet online inquiry application scene.
Step S104, when a video acquisition request is received, a corresponding complete video is obtained according to video short link replacement.
After the front end loads the video locally and initiates a network request, the server end can return the video short link immediately and obtain the corresponding complete video according to the video short link replacement, and the video specific file is downloaded according to the equipment information. For example, the device information may include mobile phone configuration information, mobile phone remaining capacity information, and the like, and the embodiment of the present application does not specifically limit the device information.
Specifically, before the corresponding complete video is obtained according to the video short link replacement, the method further comprises: acquiring a user identifier corresponding to a video acquisition request; authentication is performed based on the user identification, and in response to the authentication passing, a full video acquisition process is performed.
For example, the user identifier corresponding to the video acquisition request may be a user number or a user name, which is not specifically limited in the embodiment of the present application. For example, the user identification may be a query ID for acquiring user role information. The executing body can perform identity verification according to the obtained user identification to determine whether the user corresponding to the user identification has the authority to view the complete video. If the authentication is passed, the user identifier indicates that the corresponding user (e.g., doctor assistant or pharmacist) has the right to view the complete video, and then a complete video acquisition process may be performed to acquire the complete video for viewing to assist in diagnosis of the corresponding patient.
Specifically, performing authentication based on the user identification includes: determining a user role according to the user identification; and determining the corresponding authority according to the user role, and determining that the identity verification passes in response to the acquisition of the complete video by the authority corresponding to the opening.
The user identifier may be marked with a user role, for example, the user role represented by the mark Y in the user identifier is a doctor, the user role represented by the mark YZ in the user identifier is a doctor assistant, and the user role represented by the mark YS in the user identifier is a pharmacist. The form and content of the mark in the user identifier are not particularly limited in the embodiment of the present application. The executing body can determine the user role according to the mark in the user identifier, and determine the authority of the user role corresponding to the user identifier according to the corresponding relation between the preset user role and the authority, for example, when the user role is a doctor, the corresponding authority can be used for viewing the video file uploaded by the patient, and the identity verification is passed; when the user role is other patients, the corresponding authority can be that the video file uploaded by the patients cannot be checked, and the identity verification is not passed.
According to the embodiment, real-time hardware resource data is obtained by responding to a received video file uploading request, and then automatic slicing is performed on the video file according to the real-time hardware resource data, so that a sliced video file is obtained; obtaining hash values corresponding to the segmented video files, further executing anti-replay verification processes based on the hash values, obtaining anti-replay verification result data, further determining corresponding uploading progress display types, executing uploading operation on the segmented video files based on the uploading progress display types, responding to uploading interruption, marking interruption positions, and continuing to execute the uploading operation from the interruption positions after interruption is resumed; in response to successful uploading of each piece of video file, executing merging operation to generate a merged video file, and acquiring a video short link corresponding to the merged video file; and when receiving the video acquisition request, obtaining a corresponding complete video according to the video short link replacement. The method can realize quick and accurate uploading of the large video, reduce uncertainty caused by network problems during long-time uploading, support breakpoint continuous transmission and improve user experience.
Fig. 2 is a main flow diagram of a video file processing method according to an embodiment of the present application, and as shown in fig. 2, the video file processing method includes:
step S201, in response to receiving the video file uploading request, acquiring real-time hardware resource data, and further executing automatic slicing on the video file according to the real-time hardware resource data to obtain a sliced video file.
When the executing body receives the video file uploading request, the pre-format verification can be firstly executed, specifically, whether the format of the video file to be uploaded is one or more of Mp4, mov or Flv is verified, if yes, the uploading of the video file can be released, and if not, the uploading of the video file is refused, so that the pre-format verification is compatible with the primary end, the H5 end and the PC end.
Step S202, obtaining hash values corresponding to the segmented video files, further executing anti-replay check processes based on the hash values, obtaining anti-replay check result data, further determining corresponding uploading progress display types, executing uploading operation on the segmented video files based on the uploading progress display types, responding to uploading interruption, marking interruption positions and continuing to execute the uploading operation from the interruption positions after interruption is resumed.
The triggering condition of the uploading interrupt may be a network fault or may be congestion generated in the uploading process, and the embodiment of the application does not specifically limit the triggering condition of the uploading interrupt. When the uploading interrupt occurs, the execution body may mark a position (for example, a position a of a fragmented video file a) where the uploading interrupt occurs in the fragmented video file, and when a trigger condition of the uploading interrupt is released (for example, network recovery or congestion release), continue uploading the fragmented video file from the position (for example, the position a of the fragmented video file a) where the uploading interrupt occurs. The method and the device avoid the situation of repeated uploading or disordered uploading, and ensure the accuracy and efficiency of uploading the video file.
In step S203, in response to the successful uploading of each of the fragmented video files, a merging operation is performed to generate a merged video file.
Step S204, a first number of fragmented video files, a second number of hash values, and a total hash value corresponding to the video files are obtained.
The first number is the number of the video files to be fragmented, the second number is the number of hash values corresponding to the video files to be fragmented, and the total hash value of the video files may be the hash value corresponding to the video files when the video files are not fragmented.
Step S205, whether the first quantity and the second quantity are consistent and whether the total hash value is consistent with the hash value corresponding to the combined video file are verified, if so, the combined video file is uploaded to a cloud storage container, and a stored video short link is returned.
By verifying whether the first quantity corresponding to the fragmented video files is consistent with the second quantity corresponding to the hash values, the fragmented video files can be ensured to be consistent with the corresponding hash values, error leakage is avoided, and the uploading accuracy of the fragmented video files is ensured. By verifying whether the total hash value of the video file when the slicing is not performed is consistent with the spliced hash value corresponding to the combined video file, the loss of the sliced video file can be avoided. The merged video file may be a video file obtained by performing combination and splicing according to a time sequence corresponding to the video file when the video file is not segmented, and similarly, the hash value of the splice corresponding to the merged video file is also obtained by performing combination and splicing based on the time sequence corresponding to the video file when the video file is not segmented. If the first number and the second number are consistent and the total hash value is consistent with the hash value corresponding to the combined video file, determining that verification is passed, uploading the combined video file to the cloud storage container and returning the saved video short link can be performed.
Specifically, uploading the merged video file to a cloud storage container includes: and intercepting a first frame picture from each video file in the combined video files, performing corresponding file compression to obtain corresponding compressed video files, and associating each first frame picture with the corresponding compressed video files and uploading the first frame picture to the cloud storage container.
Fig. 4 is a schematic file operation diagram of a video file processing method according to an embodiment of the present application. Illustratively, in fig. 4, FFMPEG is employed for video file processing. Wherein FFMPEG: the method is an open source computer program which can be used for recording, converting digital audio and video and converting the digital audio and video into streams, provides a complete solution for recording, converting and streaming the audio and video, and can ensure high portability and coding and decoding quality. The first step: the original video files (such as Mp4 and Mov format video files) of the combined video file are transcoded to obtain a Flv file, and Flv is a streaming media file, and has the characteristics of high image quality and small capacity. And a second step of: and intercepting a first frame picture, wherein when the video is displayed by default, the whole video is not required to be downloaded for playing, and only the first frame of the video is required to be displayed at the moment. And a third step of: and (3) carrying out file compression on the combined video file, correlating the intercepted first frame picture with the compressed file obtained by the file compression, and uploading the correlated first frame picture and the compressed file to cloud storage. The cost of cloud storage comes from broadband, file compression facilitates fast download, and saves broadband cost.
Step S206, obtaining a video short link corresponding to the combined video file.
Step S207, when receiving the video acquisition request, obtaining the corresponding complete video according to the video short link replacement.
Specifically, after obtaining the corresponding complete video according to the video short link replacement, the method further comprises: and responding to the video acquisition request corresponding to the default display video, and displaying the first frame picture corresponding to the complete video.
After the first frame picture is intercepted, when the video is displayed by default, the complete video playing is not required to be downloaded, and only the first frame of the video is required to be displayed at the moment.
Fig. 3 is a schematic diagram of a large video file uploading process according to a video file processing method according to an embodiment of the present application. The video file processing method can be applied to a scene of uploading a large video file during internet inquiry.
