Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0026] In the description of the embodiments of the present application, unless otherwise specified, "multiple" means two or more, for example, multiple processing units means two or more processing units, etc.; multiple elements means two or more elements, etc.

[0027] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0028] Reference Figure 1 The present application provides a locally deployed pull-stream and repost method, which is applied to a server side of a locally deployed local area network, wherein the local area network also includes a video source side and a target client side. The method includes: S101 sends a request to the video source, the request is used to obtain video stream data; S102 receives the video stream data sent by the video source through the target communication protocol; S103. Perform pull-stream forwarding processing on the video stream data to obtain decoded original video data as data to be forwarded, and temporarily store the original video data; S104. Outputting the data to be forwarded through push streaming based on the push streaming protocol; S105. Distribute the data to be retweeted to other servers or target clients based on the target communication protocol.

[0029] Specifically, it is first necessary to explain that the embodiment of the present application is applied to the server side of a locally deployed local area network, and the video source side and the target client side are also deployed in the local local area network.

[0030] In step S101, the server first establishes a connection with the video source within the same local area network (LAN) and sends a request. Because the server and video source reside on the same LAN, network latency between them is low, resulting in relatively fast data transmission. The request informs the video source that the server needs to obtain the video stream data it is currently transmitting or storing.

[0031] In some optional examples, the request typically includes necessary information, such as an identifier of the video stream, a start time of the request, a duration, etc., so that the video source can accurately locate and provide the required video stream data.

[0032] The source device can be a video server, cloud platform, network camera and other devices.

[0033] In step S102, after sending the acquisition request, the server enters a waiting state, ready to receive video stream data from the video source end in the same local area network. Since they are in the same local area network, the data transmission delay and packet loss rate are relatively low, which is conducive to the server receiving data quickly and stably.

[0034] After receiving the acquisition request, the video source sends the corresponding video stream data to the server via the target communication protocol based on the request content. The target communication protocol includes but is not limited to common transmission protocols such as RTP, UDP, and TCP.

[0035] Furthermore, in step S103, after receiving the video stream data, the server needs to perform stream pulling and forwarding processing. This step involves decoding and repackaging the video stream data. First, the server needs to decode the video stream data using a corresponding decoder based on its encoding format, restoring the encoded data to the original, uncompressed video data.

[0036] After receiving the decoded raw video data, the server temporarily stores it in memory or a temporary storage device as data to be retweeted. This temporary storage facilitates subsequent streaming and distribution operations and prevents video interruptions caused by low bandwidth during media transmission. Caching technology can reduce transmission latency and improve user experience. By caching some data on the server, issues such as video playback freezes caused by network fluctuations can be avoided, ensuring real-time video transmission and high quality.

[0037] Finally, in S104 and S105, after obtaining the decoded raw video data and completing temporary storage, the server needs to push the stream to the target client or other server. In this step, the server supports a variety of commonly used video streaming protocols, including RTMP, RTSP, HLS, and other protocols. The streaming protocol defines the format, sequence, and control mechanism of data transmission, ensuring that the video data can be continuously and stably transmitted to the client in the form of a stream.

[0038] In addition to directly streaming to end users, the server can also distribute the data to be retweeted to other servers or target clients to achieve wider distribution of video content. This distribution can be carried out in a variety of ways, such as sending data to multiple recipients simultaneously through multicast technology, or sending data to a specific server or terminal through point-to-point transmission. Regardless of the method used, the server must comply with the regulations of the target communication protocol to ensure that the data can be correctly received and processed. This target protocol is similar to the protocol used by the server and the video source, and also supports a variety of commonly used media transmission protocols, including but not limited to common transmission protocols such as RTP, UDP, and TCP.

[0039] Optionally, the stream pulling and forwarding process includes video decoding process; The video decoding process specifically includes: Decapsulating the video stream data to extract coded video frames; The encoded video frame is decoded by a decoder to generate original video data corresponding to the encoded video frame.

[0040] Specifically, in the embodiment of the present application, the pulled video stream data first needs to be decoded. This process specifically includes two steps: first, the video stream data is decapsulated to separate the different data streams such as audio, video, subtitles, etc. in the video stream data, and the encoded video frames are extracted; then, the extracted encoded video frames are decoded using a decoder to restore the encoded video data to uncompressed original video data, that is, the original video data of the video frame. The decoded original video data is uncompressed, maintaining the integrity and high quality of the video content, and can be used as data to be retweeted for subsequent processing and streaming.

[0041] Optionally, the pull-stream and push-forward processing process further includes video transcoding, video protocol conversion, resolution adjustment, audio and video synchronization, and frame rate adjustment; The process of pulling and pushing specifically includes: Receiving a first input from a target client, where the first input is a video transcoding operation; Transcoding the original video data in response to the user input to obtain transcoded videos of different formats and / or different qualities; receiving a second input from a target client, wherein the second input is a video media processing operation; In response to the second input, the original video data is subjected to resolution adjustment, video synchronization processing, and frame rate adjustment.

[0042] Furthermore, in embodiments of the present application, to meet the needs of different end users or adapt to different network environments and playback platforms, the stream pulling and forwarding process may also include a series of video processing operations. These operations include: receiving video transcoding operation input from the target client, transcoding the original video data according to the user's needs, and generating transcoded videos of different formats (e.g., from H.264 to H.265) and / or different qualities (e.g., from HD to SD).

[0043] Receives video media processing operation input from the target client and performs resolution adjustment (for example, from 1080p to 720p), audio and video synchronization (ensuring synchronization of audio and video playback), and frame rate adjustment (for example, from 60fps to 30fps) on the original video data.

[0044] These processing operations can improve the user experience and ensure that video content can be played smoothly on different devices and network environments.

[0045] Optionally, the process of video protocol conversion specifically includes: Determine the communication protocol of the target platform and convert the original protocol of the original video data to be consistent with the usage protocol of the target platform.

[0046] Furthermore, when pushing video streams, different target platforms may support different communication protocols. In order to ensure that the video streaming data can be played smoothly on the target platform, video protocol conversion is required. This process specifically includes: first determining the communication protocol used by the target platform, such as RTMP, HTTP-FLV, HLS, etc.; then converting the original protocol used by the original video data into a protocol consistent with the target platform. For example, if the original video data uses the RTSP protocol, and the target platform uses the RTMP protocol, then the RTSP protocol needs to be converted to the RTMP protocol. Through protocol conversion, it can be ensured that the video streaming data is compatible with the player of the target platform, achieving smooth video playback.

[0047] Optionally, it also includes: Temporarily storing the original video data, and setting a storage time and storage duration for the temporarily stored original video data; Pulling and forwarding the video data in sequence according to the order of storage time to ensure the integrity of video transmission; The temporarily stored original video data is periodically overwritten and updated based on the storage duration.

[0048] Specifically, in order to ensure the integrity and continuity of the video data and provide a certain degree of fault tolerance, the decoded original video data can be temporarily stored. During the temporary storage process, a storage timestamp and storage duration are set for each segment of original video data. The storage timestamp is used to record the time point when the video data is stored, and the storage duration defines the retention time of the video data in the temporary storage. In the subsequent pull-stream and push-forward processing process, the system will process the video data in sequence according to the order of the storage timestamps to ensure the timing and integrity of the video content. In addition, in order to manage storage space, the system will periodically overwrite the earliest temporarily stored video data based on the storage duration. That is, when new video data needs to be stored, if the storage space is insufficient, the system will delete the stored video data with the earliest storage timestamp, thereby realizing the recycling of storage space.

[0049] Optionally, it also includes: When the streaming transmission process of the original video data is interrupted, extract the interrupted video data; The interrupted video data is re-pull-streamed and re-pushed.

[0050] Specifically, during the network transmission process, the push streaming transmission of the original video data may be interrupted due to various reasons (such as network instability, server failure, etc., and low bandwidth problems are preferably selected in this embodiment). In order to ensure the continuity and stability of video transmission, corresponding measures need to be taken when the interruption occurs. Specifically, when a push streaming interruption is detected, the system will mark and extract the video data where the interruption occurred. Then, these interrupted video data will be pulled, decoded, transcoded (if necessary), and retweeted again, and pushed again. This process may involve re-acquiring data from the video source, or extracting previously decoded original video data from temporary storage. In this way, video freezes or losses caused by transmission interruptions can be minimized, thereby improving user experience.

[0051] The use of caching technology can reduce transmission delays and improve user experience. By caching some data on the server side, problems such as video playback freezes caused by network fluctuations can be avoided, ensuring the real-time and transmission quality of video transmission.

[0052] Reference Figure 2 , Figure 2 This is a detailed workflow diagram for streaming and forwarding. As shown, the streaming and forwarding process includes decoding the original data, transcoding, protocol conversion, resolution adjustment, and audio / video synchronization. Solid lines indicate required operations, while dashed lines indicate possible operations. If low bandwidth causes interruptions in video transmission, the temporarily stored original video data can be directly used to continue streaming, ensuring video data integrity and real-time transmission. Similarly, transcoding and protocol conversion operations are performed only after the target receiving end's needs are met.

[0053] Reference Figure 3 The present application provides a locally deployed pull-stream forwarding device, comprising: The control module is used to control video requests from the video source device, decode the acquired source video, temporarily store the decoded video data, and stream and push the temporarily stored original video data. The stream pulling and pushing processing module is used to pull and push the acquired source video, including video transcoding, video protocol conversion, audio and video synchronization, frame rate adjustment and other operations. It starts the operation after receiving the command from the control module; The storage module is used to temporarily store the original video data from the source end after decoding, and starts the operation after receiving the instruction from the control module.

[0054] Specifically, the device includes the following modules: A request module is used to send an acquisition request to the video source end, wherein the acquisition request is used to obtain video stream data; A video receiving module is used to receive video stream data sent by the video source through the target communication protocol; A stream pulling and forwarding processing module is used to perform stream pulling and forwarding processing on the video stream data to obtain decoded original video data as data to be forwarded; A storage module, used for temporarily storing the original video data; A streaming module, configured to output the data to be forwarded through streaming based on a streaming protocol; A distribution module is used to distribute the data to be retweeted to other servers or target clients based on the target communication protocol.

[0055] The control module is used to control video requests from the video source, decode the acquired video stream data, temporarily store the decoded original video data, and pull and push the temporarily stored original video data.

[0056] Furthermore, the control module can control the operation of the device and other modules in the device, including controlling the device to acquire video from the video source device, controlling the stream pulling and pushing module to decode the acquired source video, controlling the storage module to temporarily store the decoded original video, controlling the stream pulling and pushing module to transcode and perform protocol conversion on the temporarily stored video, and controlling the transmission of the processed video to the target end.

[0057] Furthermore, the storage module may be a flash memory, a hard disk, a solid-state drive or other memory, or a combination of the above types of memory.

[0058] Furthermore, after receiving the instruction from the control module, the stream pulling and pushing module needs to push the video from the storage module according to the time sequence of the temporary storage of the video, and transmit the processed video to the target end.

[0059] Optionally, the stream pulling and forwarding process includes video decoding process; The video decoding process specifically includes: Decapsulating the video stream data to extract coded video frames; The encoded video frame is decoded by a decoder to generate original video data corresponding to the encoded video frame.

[0060] Optionally, the pull-stream and push-forward processing process further includes video transcoding, video protocol conversion, resolution adjustment, audio and video synchronization, and frame rate adjustment; The process of pulling and pushing specifically includes: Receiving a first input from a target client, where the first input is a video transcoding operation; Transcoding the original video data in response to the user input to obtain transcoded videos of different formats and / or different qualities; receiving a second input from a target client, wherein the second input is a video media processing operation; In response to the second input, the original video data is subjected to resolution adjustment, video synchronization processing, and frame rate adjustment.

[0061] Optionally, the process of video protocol conversion specifically includes: Determine the communication protocol of the target platform and convert the original protocol of the original video data to be consistent with the usage protocol of the target platform.

[0062] Optionally, it also includes: Temporarily storing the original video data, and setting a storage time and storage duration for the temporarily stored original video data; Pulling and forwarding the video data in sequence according to the order of storage time to ensure the integrity of video transmission; The temporarily stored original video data is periodically overwritten and updated based on the storage duration.

[0063] Specifically, further, the control module controls the storage module to set a storage time and storage duration when temporarily storing the decoded video. When controlling the operation of the pull-stream push module, it will process them in sequence according to the order of storage time to ensure the integrity of the video transmission. At the same time, the stored video data will be periodically overwritten and stored.

[0064] Optionally, it also includes: When the streaming transmission process of the original video data is interrupted, extract the interrupted video data; The interrupted video data is re-pull-streamed and re-pushed.

[0065] Furthermore, when the video is interrupted due to low bandwidth or other problems during media transmission of video data, the control module will control the pull-stream-pushing module to re-process the interrupted video and transmit it again to ensure the video transmission quality and video integrity.
