[0023] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0024] In the absence of conflict, the various embodiments of the present disclosure and the various features therein may be combined with each other.

[0025] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0026] The terms used herein are only used to describe specific embodiments and are not intended to limit the present disclosure. As used herein, the singular forms "a" and "the" are also intended to include plural forms, unless the context clearly indicates otherwise. It will also be understood that when the terms "including" and / or "made of" are used in this specification, the presence of the features, wholes, steps, operations, elements and / or components is specified, but the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or groups thereof is not excluded. "Connected" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

[0027] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted as having an idealized or overly formal meaning unless explicitly defined as such herein.

[0028] In the technical solution disclosed in this disclosure, the collection, storage, use, processing, transmission, provision and disclosure of user personal information involved are in compliance with the provisions of relevant laws and regulations and do not violate public order and good morals. The use of user data in this technical solution complies with relevant national laws and regulations (for example, the "Information Security Technology Personal Information Security Specification", etc.). For example: corresponding prescribed measures are taken for personal information access control; prescribed restrictions are imposed on the display of personal information; the purpose of using personal information does not exceed the scope of direct or reasonable association; when using personal information, clear identity orientation is eliminated to avoid precise positioning of specific individuals.

[0029] In the related art, during the video processing process, a cache is usually used to store the row data of the video frame, and then rotate or other editing processes are performed. This method mainly depends on the size of the cache capacity, resulting in limitations on the size and speed of the video that can be rotated, and this method requires processing for each video frame, and the efficiency is also low. In addition, after the rotation process is performed in the related art, the rotated data is written to the memory through the bus. In this process, usually more than one video path is written to the memory. When multiple video paths are written to the memory, the bus bandwidth requirement is also high. If the bandwidth is insufficient, it may cause garbled or errors in the video frame image.

[0030] A video processing method is provided in the embodiment of the present disclosure. The method adopts direct communication with the memory to store the video frames of the video to be processed in the memory, and then reads the video frames in the memory for editing and processing, and then writes them into the memory. Thereafter, the rotated video frames are read from the memory for display and playback. The video data read and written each time are not limited by the cache, and the editing and processing of videos of larger sizes can be supported. In addition, the method of directly communicating with the memory also effectively improves the utilization rate of the communication bandwidth.

[0031] Figure 1 The application scenario diagram of the video processing method and device provided by the embodiments of the present disclosure is schematically shown.

[0032] like Figure 1 As shown, the application scenario of the embodiment of the present disclosure may include a terminal device 101, a network 103 and a server 102. The network 103 is used to provide a medium for a communication link between the terminal device 101 and the server 102. The network 103 may include various connection types, such as wired, wireless communication links or optical fiber cables, etc.

[0033] The user can use the terminal device 101 to interact with the server 102 through the network 103 to receive or send messages, etc. Various communication client applications can be installed on the terminal device 101, such as shopping applications, web browser applications, search applications, instant messaging tools, email clients, social platform software, etc. (only as examples).

[0034] The terminal device 101 may be any electronic device having a display screen and supporting web browsing, including but not limited to a smart phone, a tablet computer, a laptop computer, a desktop computer, and the like.

[0035] The server 102 may be a server that provides various services, such as a background management server (only as an example) that provides support for websites browsed by users using the terminal device 101. The background management server may analyze and process received data such as user requests, and feed back processing results (such as web pages, information, or data obtained or generated according to user requests) to the terminal device.

[0036] It should be noted that the video processing method and apparatus provided in the embodiments of the present disclosure may be executed by the server 102. Accordingly, the video processing method and apparatus provided in the embodiments of the present disclosure may be arranged in the server 102. The video processing method and apparatus provided in the embodiments of the present disclosure may also be executed by a server or server cluster that is different from the server 102 and that can communicate with the terminal device 101 and / or the server 102. Accordingly, the video processing method and apparatus provided in the embodiments of the present disclosure may also be arranged in a server or server cluster that is different from the server 102 and that can communicate with the terminal device 101 and / or the server 102.

[0037] Alternatively, the video processing method and apparatus provided in the embodiments of the present disclosure may be executed by the terminal device 102. For example, the terminal device 102 may obtain the video to be processed from the server 102, and then the terminal device 102 may edit the video to be processed based on the video processing method in the embodiments of the present disclosure, and play the edited video.

[0038] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to the implementation requirements.

[0039] Figure 2 A flowchart of a video processing method provided by an embodiment of the present disclosure. Figure 2 , the method comprising:

[0040] Step S201: In response to a video editing instruction, each video frame of the acquired video to be processed is sequentially stored in a memory.

[0041] In the embodiments of the present disclosure, various real-time analyses and processing can be performed on the video to be processed, such as rotating the video. For example, different playback platforms may have different requirements for the direction of the video. Through rotation processing, the video can be converted into a format suitable for playback on a specific platform, etc. The video processing method in the embodiments of the present disclosure is not limited to the application scenarios. For example, it can be applied to live broadcast, monitoring, video conferencing, online education and other scenarios.

[0042] In the disclosed embodiment, during the video processing process, the video to be processed can be obtained from an input source, such as network stream acquisition, camera acquisition, etc., and then the video to be processed can be stored in a memory through a bus instead of being stored in a cache area.

[0043] Furthermore, the video editing instructions in the embodiments of the present disclosure can be triggered by, for example, a user clicking an editing function button, or according to preset video format requirements, or by editing gestures or posture changes on a device that plays the video, etc., and there are no limitations on this.

[0044] Step S202: when the editing processing condition is met, a target video frame is read from the video frames stored in the memory, and the target video frame is edited, and the edited target video frame is written into the memory.

[0045] The editing process includes at least one of the following: rotation, scaling, translation, cropping, and special effect processing, which is not limited in the embodiments of the present disclosure.

[0046] In this step S202, satisfying the editing processing condition includes: determining that the number of video frames stored in the memory is greater than or equal to a threshold; or determining that a preset processing cycle is satisfied.

[0047] When performing editing processing, when a certain number of video frames are stored, unified processing can be performed to improve processing efficiency and reduce the number of read interactions, or video frames can be read from the memory for processing at certain processing intervals, wherein the preset processing cycle usually needs to be determined based on the video playback resolution, processing speed, etc.

[0048] With respect to reading the target video frame from the video frame stored in the memory in step S202, the present disclosure also provides several possible embodiments, specifically:

[0049] In a possible embodiment, reading the target video frame from the video frames stored in the memory includes: reading the target video frame from the video frames stored in the memory every first number of frames according to a preset first number of frames.

[0050] In the embodiments of the present disclosure, compared with the storage in the cache area in the related art, which is usually stored in the cache area in the form of a video stream and needs to be edited frame by frame, the video frames of the video to be processed are stored in the memory in the embodiments of the present disclosure, and the editing process of the video frames is controllable. For example, the number of video frames to be edited per second can be set, that is, the number of first frames to be edited can be obtained, and then a video frame can be read from the memory every first frame number as the target video frame for editing. In this way, there is no need to edit every frame, which can improve efficiency and reduce resource consumption.

[0051] In another possible embodiment, reading the target video frame from the video frames stored in the memory includes: determining the second frame number according to current processing resource information; and reading the target video frame every second frame number from the video frames stored in the memory.

[0052] Among them, the current processing resource information includes, for example, bandwidth information, computing resource information, current remaining memory in the memory, etc., and there is no restriction on this. In this way, the number of second frames for interval processing can be determined dynamically in real time to better meet current needs and improve efficiency and processing performance.

[0053] In another possible embodiment, reading the target video frame from the video frames stored in the memory includes: sequentially reading each video frame stored in the memory, wherein each read video frame is used as the target video frame.

[0054] In the disclosed embodiment, it is also possible to read each video frame in sequence for editing instead of processing at intervals, which can improve the resolution and playback effect of the video after editing.

[0055] Step S203: when the playing condition is met, the edited target video frame is read from the memory, and the edited target video frame is played.

[0056] Among them, the playback conditions are, for example, playing the target video frame when it is determined that the editing process is completed, so that the edited video can be played in real time. For example, in a non-real-time playback scenario, when a playback instruction is received, it is determined that the playback conditions are met, and then the edited target video frame is read from the memory for playback.

[0057] For example, the frame rate of the video to be processed is 60 video frames displayed per second. The high frame rate can provide clearer and richer picture quality, but it will also generate more data volume, requiring a larger transmission bandwidth, processing power, etc. In the embodiment of the present disclosure, when performing editing processing, interval processing can be performed as needed. For example, a target video frame is read for editing processing every other frame, and the edited target video frame is written into the memory. Then, when playing, only the edited target video frame can be read for playback. Then, the number of video frames that can be played per second is 30, and the frame rate is lower than before, but it usually has less impact on the video display effect, and can save resources and reduce bandwidth requirements.

[0058] In the disclosed embodiment, each video frame of the video to be processed is stored in the memory in sequence. When the editing processing conditions are met, the target video frame is read from the memory, edited and then written to the memory. Then, the edited target video frame can be read from the memory for playback. In this way, in the process of editing the video, direct communication with the memory is adopted, which reduces the limitations caused by the need for additional cache, such as limitations on video size and transmission bandwidth, and improves processing efficiency and performance.

[0059] See also Figure 3 FIG. 1 is a schematic diagram of the logical architecture of video processing in an embodiment of the present disclosure.

[0060] like Figure 3 As shown, the embodiment of the present disclosure includes a video input device, a memory, a video output device and a video editor, wherein the video editor can be a video rotator, a video scaler, etc., and there is no limitation on the editing processing method.

[0061] The video input device, the video output device and the video editor are respectively connected to the memory, for example, directly connected to the memory through a bus. The video input device stores the video frames of the video to be processed in the memory. The video editor communicates with the memory through the bus, reads the video frames stored in the memory, and writes them back to the memory after editing. In this process, each bus communication with the memory is not limited by the size of the cache area, which effectively improves the bus bandwidth utilization rate and also reduces the size of the video frames read and written, which can support editing and processing of larger video sizes.

[0062] Furthermore, when the playback conditions are met, the video output device can read the edited target video frame from the memory through bus communication, and can play the edited target video frame, so that the edited effect of the video can be displayed.

[0063] It can be understood that the above-mentioned various method embodiments mentioned in the present disclosure can be combined with each other to form a combined embodiment without violating the principle logic.
