TECHNICAL FIELD

[0001] The application belongs to the technical field of streaming media, and particularly relates to an efficient live streaming distribution method for continuously growing video files. BACKGROUND

[0002] With the rapid development of network technology and the popularity of high-definition video content, live streaming services have become an indispensable part of people's daily life. However, in live streaming services, the characteristics of continuously growing video files pose a great challenge to live streaming distribution systems. Traditional live streaming distribution systems often have slow processing speed, long response time, high resource occupation and other problems when facing large-scale concurrent requests and continuously growing video files. These problems not only affect the smoothness and real-time performance of live streaming, but also increase the operating cost and limit the development of live streaming services.

[0003] In similar technologies, although there are various live streaming distribution solutions, most of them fail to effectively solve the distribution problem of continuously growing video files. Some systems use simple polling or pushing mechanisms, which cannot dynamically adjust according to the actual growth of video files and network conditions, resulting in low distribution efficiency. Some other systems are too complex, requiring high hardware investment and complex configuration management, which is not conducive to large-scale deployment and operation and maintenance. SUMMARY

[0004] In view of the above problems, the application provides an efficient live streaming distribution method for continuously growing video files, which realizes efficient and real-time distribution of continuously growing video files by introducing functions such as verification, marking, listening and waiting, data reading, configuration, queue and data sending.

[0037] S101, setting the configuration module to perform parameter configuration, wherein the parameters include the frequency of reading the video file, the size of reading the video file each time, the timeout time of the video file without change, the maximum value of the queue and the frequency of sending data; wherein the frequency of reading the video file can be adjusted to cope with the update frequency of the video file under different environments, and the processing performance can be effectively improved. The size of reading the video file each time can be adjusted to achieve the minimum packet loss rate and improve the smoothness according to the network environment. The timeout time of the video file without change can be adjusted according to the client timeout time required by the business. The maximum value of the queue can be adjusted in combination with the actual server memory resources to improve the stability of the data packet. The frequency of sending data can be adjusted according to the actual server bandwidth to improve the stability of the client playback.

[0038] S102, setting the marking module to declare variables, including a data reading thread set, an identifier bit indicating whether the live streaming identifier is being read, and a request client set of the live streaming identifier;

[0039] S103, setting the live streaming request client to perform live streaming request;

[0040] S104, setting the verification module to perform validity and legality verification of the live streaming identifier; for example, the live streaming not maintained in the system or the live streaming that has ended is directly rejected; for example, the client request outside the white list is limited.

[0041] S105, the setting mark module creates a data reading thread corresponding to the live stream identification, the mark module stores the created data reading thread information, marks the live stream identification as being read, and stores the client information of the current requested live stream identification;

[0042] S106, the setting listening waiting module creates a listener to keep the client connection, and uses whether being read as a listening interruption condition, and waits in a loop;

[0043] S107, the setting data reading module creates a separate first-in-first-out queue corresponding to the live stream identification in the queue module, the data reading module obtains configuration information from the configuration module, and the obtained configuration information includes the reading video file frequency, the size of each reading video file, the timeout time of the unchanged video file, and the maximum value of the queue;

[0044] S108, the setting data reading module creates a data sending thread corresponding to the live stream identification; the data reading module uses "whether the live stream is being read" in the mark module as an interruption condition, and uses "reading video file frequency" in the configuration module as a time interval to enter a loop waiting state, and performs a loop waiting process;

[0045] S109, after the loop ends, the thread information corresponding to the live stream identification in the mark module is removed;

[0046] S110, the data sending module uses "whether the live stream is being read" as an interruption condition, and uses "the frequency of sending data" in the configuration module as a time interval to enter a loop, and performs a loop execution;

Wherein the data packet is data information separated according to a certain size in the video file. Taking a 1MB video file as an example, if the size of each data packet is defined as 2KB, the video file includes 512 data packets.

[0050] The time difference between the current system time and the latest data packet is used as the basis to determine whether the configured "video file no change timeout time" is exceeded, if the timeout: call the marking module to set the current live stream as unread, end the related loop. The video file no change means that the video file has no new data packet generated.

[0051] If there is no timeout, read the content of the video file according to the index position and the data packet size; get the current queue size in the queue module, and use the current queue size plus the content read this time as the basis to determine whether the configured "queue maximum value" is exceeded, if exceeded: empty the current queue; update the latest data packet information, including the index position and the reading data packet time, the index position is the last index position plus the current read file size, and the data packet time is the current system time.

[0056] If not empty, multiplex the obtained data packet to send data to each client corresponding to the live stream request, that is, respond to the live stream request client, and if a client fails to send, call the marking module to remove the corresponding client.
