[0021] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

[0022] It should be clear that the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the embodiments of the present application.

[0023] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. In the description of this application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances. The singular forms of "a", "said" and "the" used in this application and the appended claims are also intended to include the plural forms, unless the context clearly indicates other meanings. The words "if" / "if" used herein can be interpreted as "at the time of" or "when" or "in response to determination".

[0024] In addition, in this application, unless otherwise specified, "plurality" refers to two or more. "And / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0025] The video publishing system of the embodiment of the present application can be applied to the content promotion and publicity scenario of the cloud screen. Among them, the cloud screen can be understood as an intelligent device with a display screen, and the content promotion and publicity scenarios of the cloud screen specifically include display screen promotion in shopping malls, desktop customization of meetings, and advertising machine advertising. In the display screen promotion scenario of a shopping mall, users can upload customized video content to the server, which is published to multiple cloud screens in the shopping mall through the server, and the video content is displayed through the video windows in each cloud screen to achieve the publicity effect of the video content. Among them, the customized video content can be the introduction information of the goods in the shopping mall and the promotion information of activities, etc. In the process of realizing the present invention, the inventor found that: for the cloud screen that displays video content, the resolution of the video window that displays the video content in the cloud screen is far lower than the video resolution of the video uploaded by the user. The cloud screen downloads the video uploaded by the user from the server, which will result in a long video download time, waste network traffic, and large performance occupancy and storage space occupancy.

[0026] To this end, the embodiment of the present application transcodes the first video according to the target video receiving end identifier and the display data of the first video component to obtain the second video, so that the transcoded second video can adapt to the target video receiving end corresponding to the target video receiving end identifier, thereby saving the network traffic of the target video receiving end, reducing the performance occupancy of the target video receiving end, and reducing the storage space occupancy of the target video receiving end.

[0027] Based on this, the present application proposes a video publishing method, system, storage medium and electronic device.

[0028] See also Figure 1 The video publishing method provided in the embodiment of the present application includes:

[0029] S10: Receive at least one first video uploaded by the video publishing end, display data of the first video component, and an identifier of a target video receiving end for receiving the first video; wherein the display data of the first video component is used to indicate a display layout of the first video component displaying the first video on the video publishing end.

[0030] The video publishing terminal displays a video publishing interface. Specifically, the video publishing interface includes but is not limited to a component selection area, a component display area, and a component control area. The component selection area is used to select and add various components, including but not limited to video components, text components, and image components. The component display area is used to display component content, and the component control area is used to control the preview, saving, and publishing of component content.

[0031] In an embodiment of the present application, a video publisher can choose to add at least one video component in the component selection area. After adding at least one video component, the component display area displays at least one first video component. Among them, the component display area can be a blank area, and the first video component is a video playback window. The video publisher can adjust the display data of the first video component. The display data of the first video component includes the display position, width ratio, height ratio and display style of the first video component in the component display area. Specifically, the video publisher can drag the first video component to change the position coordinates of the first video component in the component display area. The video publisher can scale the first video component and change the background color, transparency and other display styles of the first video component.

[0032] The component control area displays controls for previewing, saving, and publishing component content. A video publisher can trigger the preview control to preview the component content in the component display area, and trigger the save control to save the component content locally. A video publisher can publish a video in the video publishing interface, publishing the first video to the target video receiving terminal via the server. The video publishing operation triggers the publish control.

[0033] Specifically, the component control area displays a video upload control and a video receiving end list. The video publisher triggers the video upload control and uploads a first video for each first video component. The first video can be a video stored locally by the video publisher, or a video downloaded from the Internet by the video publisher. The video content in the first video can be introduction information of goods in the mall and promotion information of activities, etc. The video receiving end list includes several video receiving end identifiers, and the several video receiving end identifiers are used to uniquely identify the video receiving end. The video receiving end identifier can be the name, number, etc. of the video receiving end. The video receiving end can be each cloud screen in the mall. The video publisher can select the target video receiving end identifier to receive the first video from several video receiving end identifiers, and then click the publishing control. The video publisher responds to the triggering operation of the publishing control by the video publisher and sends the uploaded at least one first video, the display data of the first video component, and the target video receiving end identifier to receive the first video to the server.

[0034] S20: Obtain display data of the second video component according to the target video receiving end identifier and the display data of the first video component; wherein the display data of the second video component is used to indicate the display layout of the second video component displaying the second video at the target video receiving end.

[0035] The display data of the second video component includes the display position, width, height and display style of the second video component at the target video receiving end. The second video is the video played in the second video component.

[0036] In an embodiment of the present application, the server obtains the screen resolution of the target video receiving terminal based on the target video receiving terminal identifier. Based on the screen resolution of the target video receiving terminal and the width ratio and height ratio of the first video component, the width and height of the second video component at the target video receiving terminal are obtained. Based on the screen resolution of the target video receiving terminal and the position coordinates of the first video component, the position coordinates of the second video component at the target video receiving terminal are obtained. The display style of the second video component is consistent with that of the first video component.

[0037] S30: According to the display data of the second video component, the first video is transcoded to obtain a second video, and the second video is sent to the target video receiving end corresponding to the target video receiving end identifier for display.

[0038] Among them, the width and height of the second video component displayed on the target video receiving end determine the upper limit of the video resolution of the video played on the target video receiving end.

[0039] In an embodiment of the present application, a target resolution adapted to the second video component is determined based on the width and height of the second video component. The resolution of the first video is compared with the target resolution. If the resolution of the first video is greater than the target resolution, the first video is transcoded to obtain a second video with the target resolution. If the resolution of the first video is less than the target resolution, the first video is not transcoded and is directly used as the second video.

[0040] By applying the embodiment of the present application, the first video is transcoded according to the target video receiving end identifier and the display data of the first video component to obtain the second video, so that the transcoded second video can adapt to the target video receiving end corresponding to the target video receiving end identifier, thereby saving the network traffic of the target video receiving end, reducing the performance occupancy of the target video receiving end, and reducing the storage space occupancy of the target video receiving end.

[0041] In an optional embodiment, the display data of the first video component includes a first ratio of a width of the first video component to a width of the video publishing interface, and a second ratio of a height of the first video component to a height of the video publishing interface; step S20 includes steps S201 to S203, which are specifically as follows:

[0042] S201: Obtaining a screen resolution of a target video receiving end according to a target video receiving end identifier.

[0043] The first ratio and the second ratio are the percentages of the width and height of the first video component to the size of the video publishing interface, respectively. For example, if the size of the video publishing interface is 1920x 1080 and the size of the first video component is 960x 540, then the percentages of the width and height of the first video component to the size of the video publishing interface are both 0.5.

[0044] In an embodiment of the present application, the video receiving end is a cloud screen. Before several cloud screens communicate with the server, the cloud screens need to be bound to the server first, and information such as the name, serial number, and screen resolution of the cloud screens need to be uploaded to the server. The server will save this information.

[0045] S202: Determine the width of the second video component according to the screen resolution of the target video receiving end and the first ratio.

[0046] The target video receiving end is a target cloud screen, and the screen resolution of the target video receiving end includes the horizontal pixel count and the vertical pixel count of the target cloud screen.

[0047] In this embodiment of the present application, the width of the second video component is obtained by multiplying the horizontal pixel count of the target cloud screen by the first ratio. For example, if the screen resolution of the target cloud screen is 1080P and the first ratio is 0.5, the width of the second video component is 960.

[0048] S203: Determine the height of the second video component according to the screen resolution of the target video receiving end and the second ratio.

[0049] In this embodiment of the present application, the second ratio of the vertical pixel count of the target cloud screen is multiplied to obtain the height of the second video component. For example, if the screen resolution of the target cloud screen is 1080P and the second ratio is 0.5, the height of the second video component is 540.

[0050] The step of performing video transcoding on the first video according to the display data of the second video component to obtain the second video in step S30 includes steps S301 to S302, which are specifically as follows:

[0051] S301: Determine a target video resolution according to a width of the second video component, a height of the second video component, and a mapping relationship between a preset video component size and a video resolution.

[0052] Among them, in the preset mapping relationship between video component size and video resolution, one video component size corresponds to a unique video resolution.

[0053] In an embodiment of the present application, the width and height of the second video component are compared with the preset video component size, the preset video component size closest to the second video component is determined, and the video resolution corresponding to the video component size is used as the target video resolution.

[0054] S302: Perform video transcoding on the first video according to the target video resolution to obtain a second video.

[0055] In an embodiment of the present application, the video resolution of the first video is transcoded into a target video resolution to obtain a second video.

[0056] Based on the width and height of the second video component and the mapping relationship between the preset video component size and the video resolution, the target video resolution can be automatically and quickly determined.

[0057] In an optional embodiment, step S301 includes steps S3011 to S3012, which are specifically as follows:

[0058] S3011: Determine the maximum value from the width of the second video component and the height of the second video component.

[0059] In an embodiment of the present application, the server compares the size of the width of the second video component and the height of the second video component. If the second video component is 960*540, the maximum value is 960.

[0060] S3012: Determine the target video resolution according to the numerical range where the maximum value is located and the mapping relationship between the preset numerical area and the video resolution.

[0061] Among them, in the mapping relationship between the preset numerical area and the video resolution, one numerical area corresponds to a unique video resolution.

[0062] In an embodiment of the present application, the maximum value m of the width and height of the second video component is taken for matching. If 0 < m <= 640, the target video resolution is 480P; if 480 < m <= 1280, the target video resolution is 720P; if 1280 < m <= 1920, the target video resolution is 1080P; if 1920 < m <= 4096, the target video resolution is 4K.

[0063] For example, if the uploaded first video is a 4K video, a 720P second video is transcoded. The target video receiver with the second video component width and height of 2048*1080 plays the 4K first video, and the target video receivers with the second video component width and height of 960*540 and 640*360 play the 720P video.

[0064] If the uploaded first video is a 1080P video, a 720P second video is transcoded. The target video receiver with the second video component width and height of 2048*1080 plays the 1080P first video, and the target video receivers with the second video component width and height of 960*540 and 640*360 play the 720P second video.

[0065] Based on the maximum value of the width and height of the second video component and the mapping relationship between the preset numerical area and the video resolution, the target video resolution can be automatically and quickly determined.

[0066] In an optional embodiment, step S302 includes step S3021, which is specifically as follows:

[0067] S3021: Perform video transcoding on the first video according to the target video resolution, the preset bit rate, and the preset encoding format to obtain a second video.

[0068] In the embodiment of the present application, considering that different cloud screens have different video decoding capabilities, some low-performance cloud screens may not support high-bitrate videos or video formats, resulting in unsuccessful video decoding and abnormal video playback. To this end, the server transcodes the first video into a second video with a universal bitrate and universal encoding format to avoid playback anomalies in the second video. Specifically, the universal bitrate is less than or equal to 10Mps, and the universal encoding format is H.264.

[0069] Optionally, the server can also limit the frame rate, packaging format, pixel format, maximum video resolution, and video compression rate of the second video to maximize the compatibility of the second video on different cloud screens and avoid playback anomalies of the second video. For example, the frame rate is less than 30fps, the packaging format is MP4, the maximum video resolution is 4K, the pixel format is not converted by default, and the video compression rate is not converted below main.

[0070] In an optional embodiment, before sending the second video to the target video receiving end corresponding to the target video receiving end identifier for display, steps S1 to S4 are included, which are specifically as follows:

[0071] S1: Generate a first video identifier based on the first video; generate a web page link based on the display data of the first video component and the first video identifier; and send the web page link to a target video receiving end corresponding to the target video receiving end identifier.

[0072] The first video identifier is used to identify the storage location of the first video on the server. The first video identifier can be a video link or a video address.

[0073] In an embodiment of the present application, when the video publisher publishes the first video, the server generates a web link and sends it to the target cloud screen. Specifically, after receiving the first video sent by the video publisher, the server saves the first video and generates a first video identifier. After receiving the display data of the first video component sent by the video publisher, the server generates a web link based on the display data of the first video component and the first video identifier, and sends the web link to the target cloud screen.

[0074] S2: Generate a second video identifier based on the second video; and establish an association relationship among the first video identifier, display data of the second video component, and the second video identifier.

[0075] The second video identifier is used to identify the storage location of the second video in the server 20. The second video identifier can be a video link or a video address.

[0076] Among them, in the association relationship among the first video identifier, the display data of the second video component and the second video identifier, the first video identifier and the display data of the second video component jointly determine a unique second video identifier.

[0077] In an embodiment of the present application, after transcoding the first video, the server obtains the second video, saves the second video, and generates a second video identifier.

[0078] Since there can be multiple first videos and multiple target video receiving terminals, there can also be multiple second videos stored on the server. By establishing an association between the first video identifier, the display data of the second video component, and the second video identifier, the corresponding second video identifier can be determined based on the first video identifier and the display data of the second video component, thereby determining the second video corresponding to the second video identifier.

[0079] S3: Receive a video playback request sent by the target video receiving end. The video playback request is a response by the target video receiving end to a trigger operation on a web page link, and obtains the display data of the first video component according to the web page link; determines the display data of the second video component according to the display data of the first video component; and generates according to the display data of the second video component and the first video identifier.

[0080] In an embodiment of the present application, a user clicks a web link on the target cloud screen to access the web page corresponding to the web link. The web page displays a second video component. Specifically, the target cloud screen responds to the click operation on the web link, parses the web link, obtains the display data of the first video component and the first video identifier. The screen resolution of the target cloud screen is obtained, and the second video component is displayed according to the display data of the first video component and the screen resolution of the target cloud screen. The process of determining the display data of the second video component according to the display data of the first video component is consistent with the process of the server obtaining the display data of the second video component, and will not be repeated here.

[0081] S4: Parse the video playback request, determine the corresponding second video identifier according to the first video identifier and the display data and the association relationship of the second video component; and send the second video corresponding to the second video identifier to the target video receiving end.

[0082] In an embodiment of the present application, the server stores multiple second videos, each of which corresponds to a unique second video identifier. The server searches for the corresponding second video identifier based on the first video identifier and the display data of the second video component carried in the video playback request, and sends the second video corresponding to the second video identifier to the target video receiving terminal.

[0083] Among them, considering that in the server, a first video can be transcoded into multiple second videos with different video resolutions, the server can only determine which second video to return if the target cloud screen provides the first video identifier corresponding to the first video and the width and height of the second video component at the same time.

[0084] For example, if there are two video components on the video publishing interface, one video component accounts for 100% of the width and height of the video publishing interface, and the other video component accounts for 10% of the width and height of the video publishing interface. If the first video is 4K, the video component with a width and height of 100% should play the second video in 1080P, and the video component with a width and height of 10% should play the second video in 420P. Since the first videos corresponding to the two video components are the same, only the first video identifier is sent to the server, and the server may return 1080P or 420P. Therefore, the first video identifier and the width and height of the second video component are sent to the server, and the server can return the corresponding second video to each second video component.

[0085] By receiving the video playback request sent by the target cloud screen, the server can accurately return the corresponding second video to the target cloud screen.

[0086] In an optional embodiment, step S4 includes steps S401 to S402, which are specifically as follows:

[0087] S401: Parse the video playback request and determine whether a corresponding second video identifier is found based on the first video identifier, display data of the second video component, and the association relationship.

[0088] S402: When the corresponding second video identifier is found, the corresponding second video is determined according to the second video identifier; and the second video is sent to a target video receiving end.

[0089] In an embodiment of the present application, when the server starts video transcoding, the target cloud screen will also receive a web link. When the target cloud screen responds to the trigger operation of the web link and sends a video playback request to the server, the server may be performing video transcoding, or the video transcoding may be completed, or the video transcoding may have failed. Therefore, after receiving the video playback request, the server will determine whether the corresponding second video identifier is queried. If the corresponding second video identifier is queried, it means that the second video has been transcoded, and the second video is sent to the target cloud screen so that the second video component of the target cloud screen plays the second video. If the corresponding second video identifier is not queried, the video transcoding status is detected and the video transcoding status is returned to the second video component of the target receiving end. Specifically, if the first video is being transcoded, the second video component displays "Video Preparing"; if the first video transcoding fails, the second video component displays "Video Abnormal".

[0090] The server can automatically and quickly send the second video to the target cloud screen by determining whether the corresponding second video identifier is found.

[0091] See also Figure 2 The video publishing system 1 provided in the embodiment of the present application includes a video publishing terminal 10, a server 20 and a plurality of video receiving terminals; the video publishing terminal 10 and the plurality of video receiving terminals 30 are respectively connected to the server 20 for communication;

[0092] In response to a video publishing operation on the video publishing interface, the video publishing terminal 10 transmits at least one uploaded first video, display data of the first video component, and an identifier of a target video receiving terminal for receiving the first video to the server 20; wherein the display data of the first video component is used to indicate a display layout of the first video component displaying the first video on the video publishing terminal 10;

[0093] The server 20 obtains display data of the second video component according to the target video receiving terminal identifier and the display data of the first video component; wherein the display data of the second video component is used to indicate the display layout of the second video component displaying the second video at the target video receiving terminal;

[0094] The server 20 performs video transcoding on the first video according to the display data of the second video component to obtain a second video, and sends the second video to the target video receiving end corresponding to the target video receiving end identifier for display.

[0095] The specific process of the above system embodiment is consistent with the method embodiment and will not be repeated here.

[0096] In an optional embodiment, before the server 20 sends the second video to the target video receiving end corresponding to the target video receiving end identifier for display, the server 20 includes the following steps:

[0097] The server 20 generates a first video identifier based on the first video; generates a web link based on the display data of the first video component and the first video identifier; and sends the web link to the target video receiving end corresponding to the target video receiving end identifier;

[0098] The server 20 generates a second video identifier based on the second video; establishes an association relationship between the first video identifier, the display data of the second video component, and the second video identifier;

[0099] The target video receiving end displays the web link; in response to a triggering operation on the web link, obtains display data of the first video component according to the web link; determines display data of the second video component according to the display data of the first video component; generates a video play request according to the display data of the second video component and the first video identifier; and sends the video play request to the server;

[0100] The server 20 parses the video playback request, determines the corresponding second video identifier based on the first video identifier, the display data of the second video component, and the association relationship; and sends the second video corresponding to the second video identifier to the target video receiving end.

[0101] The steps of the above system embodiment can be referred to steps S1 to S4 in the method embodiment, which will not be repeated here.

[0102] In an optional embodiment, the video publishing system 1 further includes:

[0103] Each time the second video is played, the target video receiving end saves the first video identifier, the second video identifier, and the display data of the second video component corresponding to the second video into a cache.

[0104] In an embodiment of the present application, the target cloud screen will cache web page data and save the first video identifier, the second video identifier and the display data of the second video component corresponding to the second video into the cache. Specifically, it is cached in the form of an index key-value pair, the first video identifier corresponding to the second video is the index key, and the second video identifier corresponding to the second video and the display data of the second video component are the values ​​of the index key. For example, {key: first video identifier, result: [url: 1080P second video identifier (corresponding to the second video 1080p) width: 1920, height: 1090}, {url: second video identifier (corresponding to the second video 720P) width: 1280, height: 720}]}.

[0105] In an offline state, the target video receiving end searches for a corresponding second video identifier from a cache according to display data of the current video component and the current first video identifier; and obtains a corresponding second video according to the corresponding second video identifier.

[0106] In the offline state, it is impossible to query the server 20 for the corresponding second video identifier. At this time, the target cloud screen needs to match the second video identifier cached locally.

[0107] In an embodiment of the present application, the target cloud screen uses the current first video identifier to query the second video identifier set corresponding to the current first video identifier from the index key-value pair, and then compares the display data of the current video component with the display data of the second video component in the second video identifier set to determine the display data of the second video component closest to the display data of the current video component, and determines the second video identifier corresponding to the display data of the closest second video component as the queried second video identifier.

[0108] The target cloud screen can play the second video in an offline state by caching web page data.

[0109] In an optional embodiment, in an offline state, the target video receiving end queries the corresponding second video identifier from the cache according to the display data of the current video component and the current first video identifier, including:

[0110] The target video receiving end queries the corresponding second video identification set according to the current first video identification; wherein the second video identification set includes a plurality of second video identifications and the width and height of the second video component corresponding to each second video identification;

[0111] The target video receiving end determines the maximum value between the width of the current video component and the height of the current video component, and calculates the difference between the maximum value and the maximum value between the width of the second video component corresponding to each second video identifier and the height of the corresponding second video component;

[0112] The target video receiving end uses the second video identifier with the smallest difference as the second video identifier to be searched from the cache for a match.

[0113] In an embodiment of the present application, the maximum value n of the width and height of the current video component is first determined. If the current video component is 1800x 1200, then n is 1800. Then, the maximum value of the width of the second video component corresponding to the cached second video identifier and the height of the corresponding second video component and the difference between n are calculated, and the second video identifier with the smallest difference is determined as the matching second video identifier. For the second video identifier (corresponding to the second video 1080P), the maximum value is 1920, and for the second video identifier (corresponding to the second video 720P), the maximum value is 1280. The differences with n are 120 and 520 respectively. The second video identifier corresponding to the second video 1080P should be taken.

[0114] By comparing the maximum value of the width and height of the current video component with the maximum value of the width and height of the second video components in the second video identifier set, the second video identifier of the current video component can be automatically and quickly determined.
