[0051] In conjunction with the accompanying drawings, the video file sharing method, device, equipment and medium provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0052] Embodiment 1

[0053] Figure 1 1 is a flow chart of a video file sharing method provided in Example 1 of the present application. Figure 1 As shown, the specific steps include:

[0054] S101, in response to a video file upload request, obtaining department information of the uploading user;

[0055] First, this application is applicable to the scenario of video file sharing within a company or department. Based on the above scenario, it can be understood that the execution subject of this application can be a terminal device or system with the ability to upload, organize and share video files.

[0056] Video files may include audio, video, or any other file format. For example, a video file may be a video tutorial that different groups in the art department of an application need to share in the intranet. In this example, the upload request for the video file may be issued by a member of the art department. Because in some scenarios, the development or design of an application requires coordination among all departments, the upload request may be issued to a member of any department of the application. Because some companies also involve scenarios that require resource synchronization, the upload request may also be issued by a member of any department of the company.

[0057] The uploading user is the user who sends the upload request. The department information of the user may be associated with the work number of the user. The department information of the user may be identified based on the work number, name or identity ID of the user.

[0058] S102, determining an upload directory of the video file in all directories of the video sharing library according to the department information of the uploading user;

[0059] After determining the department information, the upload directory of the video file in the video sharing library for the uploading user can be determined based on the department information. It can be understood that if the video sharing library is built based on an application developed by a company, the directories associated with the various functional modules of the application can be set. If the video sharing library is built based on the company dimension, all directories can include the various departments of the company and the branches under the departments, etc.

[0060] In this solution, if the department information of the uploading user is the character model making department of the art department, after the uploading user sends an upload request, the uploaded video file can be stored in all directories and in the directory of the character model making department of the art department.

[0061] In this solution, after uploading, the user's work number information, identity ID or IP address used for uploading can be stored at the same time to indicate the identity of the uploading user. The uploading time information, uploading duration information, etc. can also be stored at the same time after uploading. This can be used to assist other browsing users in browsing and understand the relevant information when the video file is uploaded based on the above information.

[0062] In one embodiment, optionally, determining the upload directory of the video file in all directories of the video sharing library according to the department information of the uploading user includes:

[0063] Identify whether the department information of the uploading user is within the scope of the existing departments of the video sharing library;

[0064] If it is within the scope of an existing department, matching the target department according to the department information of the uploading user, and determining the upload directory of the target department as the upload directory of the video file in the video sharing library;

[0065] If it is not within the scope of the existing department, a new department directory is created according to the department information of the uploading user, and the new department directory is determined as the upload directory of the video file in the video sharing library.

[0066] There may be a situation where the department information of the uploading user is not within the scope of the existing departments of the video sharing library. For example, the user issues an upload request for a video file, and the department to which the uploading user belongs happens to be a newly established department. In this case, in order to ensure the accuracy of the upload directory, the department information of the uploading user will be matched with the existing departments of the video sharing library. If the match is successful, the upload directory of the matched target department will be determined as the upload directory of the video file in the video sharing library. If the match fails, a new department will be created with the department information of the uploading user, and an upload directory corresponding to the new department, i.e., a new department directory, will be established, and the new department directory will be determined as the upload directory of the video file in the video sharing library.

[0067] The technical solution provided in this embodiment can realize the operation of matching the department information of the uploading user, and then realize the accurate management of the upload directory of the video files uploaded to the video sharing library, which is convenient for the subsequent search of shared resources, makes the division of shared resources clearer, and improves the user experience of the video file sharing process.

[0068] S103, receiving a video file, and storing the video file in a corresponding position of the upload directory;

[0069] After determining the upload directory, the video file can be received and stored in the corresponding position of the upload directory. That is, if the upload directory points to a fixed storage location, the video file will be stored therein. It is understandable that if the size of the storage space of the corresponding position of the upload directory is not specified in advance, the video file can be received and stored. If the size of the storage space is specified, it is necessary to identify whether the storage space is sufficient to store the video file before storage. If it is insufficient, the corresponding position of the upload directory needs to be expanded. For example, the default expansion is 2GB each time. After three expansions, a corresponding notification instruction will be generated, so that the administrator of the video sharing library can make specific checks and adjustments on whether the directory allocation is reasonable and whether the space size setting is reasonable.

[0070] S104, in response to a video file browsing request sent through a Web page, identifying department information of a browsing user;

[0071] Web (World Wide Web) is the global wide area network, also known as the World Wide Web. It is a global, dynamically interactive, cross-platform distributed graphical information system based on hypertext and HTTP. It is a network service built on the Internet, which provides a graphical, easy-to-access and intuitive interface for viewers to find and browse information on the Internet. The documents and hyperlinks organize the information nodes on the Internet into an interconnected mesh structure. A web page is a web page, which can be a page in a website. Usually, a web page is the basic element of a website and is a platform for carrying various website applications. In layman's terms, a website is composed of web pages.

[0072] In this solution, the video sharing library can be accessed through a Web page, which can improve the availability of the video sharing library and make it more convenient to use without complicated operations.

[0073] When a video file browsing request is received through a Web page, the department information of the browsing user will be identified.

[0074] S105, determining, according to the department information of the browsing user, a visible directory of the video sharing library for the browsing user; wherein the visible directory is part or all of all directories of the video sharing library;

[0075] According to the department information of the browsing user, permission identification can be performed to determine which resources in the video sharing library are visible to the browsing user, and then determine the visible directory. It can be understood that if the browsing user has permission to view all video files shared by all departments, the visible directory is equal to all directories. If only video files shared by some departments can be viewed, the visible directory is a part of all directories.

[0076] For example, during the development of application A, departments X, Y, and Z participated, and during the development of application B, departments X and W participated. In the video sharing library developed by the company, browsing users of department W only have the right to access video files shared by departments X and W for application B. If browsing users of department X only participated in the development of application A, then the browsing users only have the right to access video files shared by departments X, Y, and Z for application A.

[0077] S106, in response to the selection operation on the visual directory, determining a target location in the visual directory, and providing a video file corresponding to the target location to the Web page.

[0078] After the browsing user selects a target location based on the visible directory, the video file corresponding to the target location can be fed back to the Web page for the browsing user to watch.

[0079] The technical solution provided in this embodiment obtains the department information of the uploading user in response to the upload request of the video file; determines the upload directory of the video file in all directories of the video sharing library according to the department information of the uploading user; receives the video file and stores the video file in the corresponding position of the upload directory; identifies the department information of the browsing user in response to the video file browsing request issued through the Web page; determines the visible directory of the video sharing library to the browsing user according to the department information of the browsing user; wherein the visible directory is part or all of all directories of the video sharing library; determines the target location in the visible directory in response to the selection operation of the visible directory, and provides the video file corresponding to the target location to the Web page. The technical solution provided in this application can realize the sharing of video files with clear directories in the process of video file sharing, reduces the complexity of operation for both the sharing personnel and the browsing personnel, and can realize the simplified management of shared video files, and has a large scope of application.

[0080] Based on the above technical solutions, optionally, after determining the upload directory of the video file in all directories of the video sharing library according to the department information of the uploading user, the method further includes:

[0081] Identify whether the encoding format of the video file in the video sharing library meets the preset format standard;

[0082] If not, the video file is transcoded to obtain a target encoding format.

[0083] Among them, a video file itself usually consists of two parts: audio and video. For example, a video file is composed of avc video encoding + AAC audio encoding. Common video encoding formats include Xvid, AVC / H.264, MPEG1, MPEG2, etc. Common audio encoding formats include MP3, AAC, etc. Different encoding formats have different characteristics. For example, AVI, which means Audio Video Interactive, is to store video and audio encoding together. The AVI format has many restrictions. There can only be one video track and one audio track, and there can be some additional tracks, such as text. The AVI format does not provide any control function. WMV, Windows Media Video, is the general name for a group of digital video codec formats developed by Microsoft. ASF (Advanced Systems Format) is its packaging format. MPEG format, MPEG (Moving Picture Experts Group), is a media packaging form recognized by the International Organization for Standardization (IS0) and supported by most machines. Its storage methods are diverse and can adapt to different application environments. The file container format of MPEG-4 files is specified in Layer 1 (mux), 14 (mpg), 15 (avc), etc. MPEG has rich control functions, and can have multiple videos (i.e. angles), audio tracks, subtitles (bitmap subtitles), etc. MPEG1 is an MPEG (Moving Picture Experts Group) multimedia format used to compress and store audio and video. Used in computers and games, MPEG1 has a resolution of 352*240 pixels and a frame rate of 25 frames per second (PAL). MPEG2 is an MPEG (Moving Picture Experts Group) multimedia format used to compress and store audio and video. For use in broadcast-quality applications, MPEG 2 defines protocols that support the addition of closed captions and various language channel functions. DivX / xvid, DivX is a digital multimedia compression technology invented by DivX Networks that is similar to MP3. DivX is based on MPEG-4 and can compress MPEG-2 format multimedia files to 10% of the original, and can also compress VHS format videotape format files to 1% of the original. Through broadband devices such as DSL or Cable Moden. At the same time, it allows viewing on other devices (such as digital TV, Blu-ray player, PocketPC, digital photo frame, mobile phone) with low machine requirements. This encoded video can be played smoothly as long as the CPU is above 300MHz, 64M memory and a graphics card with 8M video memory. DivX files are small and the image quality is better. A CD-ROM can hold 120 minutes of movies with quality close to DVD. DV, digital video, is usually used to refer to devices (such as portable cameras) that capture and store video in digital format.There are two types of AVI files, DV Type I and DV Type II. DV Type I, digital video AVI files contain original video and audio information. DV Type I files are usually smaller than DV Type II files and are compatible with most A / V devices, such as DV camcorders and recorders. DV Type II, digital video AVI files contain original video and audio information, and also contain a separate audio track as a copy of the DV audio. DV Type II is more widely compatible with software than DV Type I, because most programs that use AVI files expect to use a separate audio track. MKV, Matroska is a new multimedia packaging format that can package multiple differently encoded videos and 16 or more audios in different formats and subtitles in different languages ​​into a Matroska Media file. It is also one of the open source multimedia packaging formats. Matroska can also provide very good interactive functions, and is more convenient and powerful than MPEG. RM / RMVB, Real Video or Real Media (RM) files are a file container developed by RealNetworks. It can usually only accommodate media encoded with Real Video and Real Audio. The file has certain interactive functions and allows scripts to be written to control playback. RM, especially the variable bit rate RMVB format, is very small and very popular among Internet downloaders. MOV, QuickTime Movie is a container developed by Apple. Due to the dominance of Apple computers in the professional graphics field, the QuickTime format has basically become a universal format in the film production industry. On February 11, 1998, the International Organization for Standardization (IS0) recognized the QuickTime file format as the basis of the MPEG-4 standard. QT can store a wealth of content. In addition to video and audio, it can also support pictures, text (text subtitles), etc. OGG, Ogg Media is a completely open multimedia system plan, and OGM (Ogg Media File) is its container format. OGM can support multiple tracks such as multiple videos, audios, subtitles (text subtitles), etc. MOD format is the name of the storage format used by hard disk camcorders produced by JVC.

[0084] The preset format standard may be one or more of the above-mentioned formats. Identifying whether the encoding format of the video file in the video sharing library meets the preset format standard may be identifying whether the encoding format of the video file is within the range of the preset format standard. If it is within the range of the preset format standard, it is determined that the requirement is met and no processing is required. If it is not met, the video file is transcoded to obtain the target encoding format.

[0085] It should be noted that the preset format standard can be one format or multiple formats. The formats in the preset format standard need to meet the requirements of being able to be played on a web page, so as to ensure that the video files in the video sharing library can be successfully viewed by browsing users. Otherwise, the video sharing effect cannot be achieved.

[0086] Through such a setting, this solution can ensure that each video file in the video sharing library can be shared successfully, improve the user experience during the uploading or browsing process, avoid a series of complex operations caused by sharing failure, or problems that affect the work progress of staff.

[0087] Based on the above technical solutions, optionally, after determining the upload directory of the video file in all directories of the video sharing library according to the department information of the uploading user, the method further includes:

[0088] The video metadata of the video files in the video sharing library are automatically changed through a preset tool.

[0089] Video metadata can be data such as the thumbnail and video title of the video file in the video sharing library. After uploading the video file to the video sharing library, you can use preset tools to collect and automatically identify and change it. For example, if the AI ​​tool recognizes that the main body of the video is a video related to children's education, you can change its video title to: Children's Education Video.

[0090] It is understandable that the preset tool can be an AI tool or other tools, for example, it can be a tool for uniformly modifying the names of video files, such as encoding them sequentially according to the order of upload time.

[0091] This embodiment can automatically change the video metadata of the video file after the video file is uploaded to the video sharing library through the automatic change operation of the video metadata, so that the processed video file can be better displayed in the video sharing library, and can help other users quickly understand the content of the video file when other users browse it.

[0092] Based on the above technical solutions, optionally, the video metadata of the video files in the video sharing library are automatically changed by a preset tool, including:

[0093] The video file in the video sharing library is intercepted with a video frame through OpenCV, and the video frame is used as a preview image of the video file.

[0094] OpenCV, the full name of Open Source Computer Vision Library, is an open source computer vision library mainly used for image and video processing. It was first developed by Intel in 1999 and has evolved into a global open source project maintained and contributed by many developers. OpenCV is available on a variety of operating systems and platforms, including Windows, Linux, macOS, Android, and iOS. The core of OpenCV is written in C++, but it provides interfaces to multiple programming languages ​​such as Python, Java, MATLAB, etc., allowing developers to use the functions of OpenCV through familiar languages. These interfaces have greatly lowered the threshold for using computer vision technology and attracted a wide range of application fields. OpenCV has very rich functions, including but not limited to image processing, video analysis, object detection and tracking, image feature extraction and description, implementation of machine learning and deep learning algorithms, as well as camera calibration and 3D reconstruction. It also provides advanced functions such as various image filters, histogram operations, binarization, shape descriptor calculation, etc. The modular structure of OpenCV makes it easy to expand and maintain. Its main modules include core functions, image processing, video analysis, feature extraction and description, object detection, high GUI interface, video input / output, GPU acceleration algorithms, etc. OpenCV is widely used in many fields, such as face recognition, gesture recognition, human-computer interaction, action recognition, motion tracking, object recognition, image segmentation, robotics, etc. It has rich documentation and numerous sample codes, providing developers with convenient learning resources.

[0095] In this solution, by utilizing the video processing function of OpenCV, a certain video frame in the video file is intercepted as a preview image, and the video information is generated or updated and stored. Here, generating the video information means using the video frame as a preview image of the video file. It can be understood that the operation of intercepting the video frame through OpenCV can be to identify the video frames in the video file one by one, and determine a video frame that best represents the content of the video file as the preview image of the video file, so that the browser or uploader can have a preliminary understanding of the content displayed by the video file based on the preview image.

[0096] Through such a setting, the present embodiment can use OpenCV technology to automatically replace the preview image of the video file. After the uploader uploads the video, the preview image of the video file can be seen, and when the browsing person enters the directory, he can also see the video file with the preview image. This setting can not only automatically generate images for users to browse, but also save the uploader from complicated operations to select preview images, so that the uploader can achieve the purpose of automatically generating preview images based on simple uploading operations.

[0097] Based on the above technical solutions, optionally, before intercepting the video frame of the video file in the video sharing library through OpenCV, the method further includes:

[0098] Identifying whether the video file has a manually specified preview image;

[0099] If not, an operation of capturing video frames from the video file is performed.

[0100] In this solution, before OpenCV captures a video frame from a video file in the video sharing library, it is necessary to identify whether the video file has been manually specified with a preview image by the uploading user or other personnel. For example, a label can be generated after the preview image is manually specified, indicating that a historical event of manually specifying a preview image has occurred in the video file.

[0101] After a manually specified preview image is identified, the operation of capturing a video frame of the video file will not be performed, or an operation of capturing a video frame of the video file will be performed, but the preview image obtained by the operation will not overwrite the manually specified preview image.

[0102] After identifying that there is no manually specified preview image, an operation of capturing a video frame of the video file may be performed, and the captured video frame may be used as a preview image of the video file.

[0103] Through such a setting, the present solution can automatically generate a preview image for a video file, and after recognizing that the user has already specified a preview image for the video file, the preview image specified by the user will not be overwritten.

[0104] Embodiment 2

[0105] Figure 2 It is a flowchart of the encoding format processing of the video file provided in the second embodiment of the present application. This solution makes a better improvement on the above embodiment, and the specific improvement is: identifying whether the encoding format of the video file in the video sharing library meets the preset format standard, including: obtaining the target encoding format supported by the Web page; identifying whether the encoding format of the video file in the video sharing library is the same as the target encoding format; if the same, it is determined to meet the preset format standard; if different, it is determined to not meet the preset format standard; transcoding the video file to obtain the target encoding format, including: performing ffmpeg transcoding on the video file to obtain the mpeg encoding format.

[0106] like Figure 2 As shown, the specific steps include:

[0107] S201, obtaining a target encoding format supported by the Web page;

[0108] Among them, the target encoding format supported by the web page can be the encoding format of the video that can be opened and played normally in the web page. The target encoding format can be one or more. After the supported target encoding formats are determined, they can be updated according to actual conditions to add, delete or replace one or more target encoding formats.

[0109] S202, identifying whether the encoding format of the video file in the video sharing library is the same as the target encoding format; if the same, executing S203; if not the same, executing S204;

[0110] Among them, if the encoding format of the video file in the video sharing library is the same as any one of the target encoding formats, the encoding format of the video file does not need to be modified, that is, it meets the preset format standard. If the encoding format of the video file in the video sharing library is different from each of the target encoding formats, the encoding format of the video file needs to be modified, that is, it does not meet the preset format standard.

[0111] S203, determining that the preset format standard is met;

[0112] S204, determining that the preset format standard is not met, and performing ffmpeg transcoding on the video file to obtain an mpeg encoding format.

[0113] If the preset format standard is not met, the video file can be transcoded using ffmpeg to obtain an mpeg encoding format.

[0114] Among them, ffmpeg transcoding is a very powerful multimedia processing tool that can be used to transcode video and audio. For example, using ffmpeg transcoding for video transcoding, you can convert a video file from one format to another. For example, convert a .mp4 file to .avi format:

[0115] ffmpeg-iinput.mp4 output.avi;

[0116] In addition, ffmpeg can also adjust the video resolution, for example, adjust the video resolution to 1920x1080:

[0117] ffmpeg-iinput.mp4-vf"scale=1920:1080"output.mp4;

[0118] Additionally, ffmpeg can adjust the video bitrate or compression level, for example, to compress the video using more efficient encoding settings:

[0119] ffmpeg-iinput.mp4-crf 23output.mp4;

[0120] The -crf parameter is used to control the quality and compression rate of the video. The smaller the value, the higher the quality.

[0121] In addition, ffmpeg can also perform audio transcoding, such as extracting audio from one format or converting it to another format, such as extracting audio from a video file and saving it in .wav format:

[0122] ffmpeg-iinput.mp4-vn-acodec pcm_s16le output.wav;

[0123] Among them, -vn means not processing the video stream, only the audio stream. -acodec is used to specify the audio encoder.

[0124] The technical solution provided in this embodiment can ensure that browsing users can smoothly watch video files in the subsequent sharing stage by converting the format of video files into MPEG encoding format, avoiding the situation where video files cannot be played after uploading due to encoding format problems, affecting the user experience.

[0125] Figure 3 Schematic diagram of the video file sharing process provided in the second embodiment of the present application. Figure 3 As shown, this solution can adopt the following steps:

[0126] Step 1: If a new department joins, first configure the video sharing library such as samba to upload permissions to the corresponding directory to the new department.

[0127] Step 2: The user uploads the video file to the corresponding directory of the video sharing library.

[0128] Step 3: The application regularly and deeply traverses the video sharing library. If the video encoding does not match (the target format is mpeg format, or the format cannot be played normally on the web page), ffmpeg transcoding is performed. OpenCV captures the video frame as a preview image and generates or updates the video information into the library.

[0129] Step 4: Users can browse the referenced web page to browse the video catalog by department and click on the details to browse the video in the exact order of fuzzy matching. Video metadata such as preview images can also be modified, and the application will not overwrite the manually modified preview images.

[0130] For example, different groups in the art department need to share and view internal or online video tutorials, such as sharing the latest AI video painting technology. By building a video management WEB page, video integrated management and single-page browsing can be achieved.

[0131] In the above solution, the video sharing library can use samba or various open source sharing software. You can also consider "mirror replication" of the shared library for high availability.

[0132] Web pages such as Nginx can embed the original video address and also divert the video to reduce network bandwidth and improve availability.

[0133] Through the above settings, the technical solution allows users to browse corresponding videos on the web page after uploading videos to the shared library according to the rules; after the user uploads the video, the video is automatically sorted into chapters and nested in sub-directories. In addition, there can be a clearer departmental video directory browsing and retrieval effect than file directory management. For some special video files, users do not need to install the corresponding player but can be uniformly transcoded, which expands the scope of application.
