The HLS technology encodes video source content according to a plurality of set code rates (the code rate is from low to high and represents that the video quality is from poor to good) through an encoder, divides the content of each code rate into a plurality of TS fragments with fixed time duration, and simultaneously generates a main index file and a secondary index file in an m3u8 format. The main index file records code rate information and addresses (such as URL addresses) of respective corresponding secondary index files, and the secondary index files record information such as duration, file names and index addresses of each TS fragment under the code rate. The user terminal analyzes the main index file after downloading the main index file, and adaptively selects the secondary index file and the TS fragment with corresponding code rates according to the network bandwidth condition of the user terminal, so that the user can obtain smooth and unsmooth user experience under different network bandwidth conditions. An exemplary HLS content structure is shown in fig. 1, where a.m3u8 is a main index file, and records three bit rates of 200000bps, 484444bps and 737777bps and URL addresses of secondary index files index.m3u8 corresponding to the three bit rates; the second-level index file records TS fragment information at the code rate, # EXTINF represents the fragment duration, and 001.TS and 002.TS … …. TS are the file names of the fragments.
After the analysis, the inventor adjusts the storage form of the streaming media content in the network, and dynamically modifies the main index file to guide the user terminal to the corresponding network position to obtain the streaming media file.
Fig. 2 is a flow chart illustrating a streaming media communication method according to some embodiments of the invention. As shown in fig. 2, the streaming media communication method of this embodiment includes steps S202 to S214. The steps not indicating the execution subject may be performed in the cloud, for example, by a cloud server.
In step S202, an acquisition request of the first terminal for the target streaming media content is acquired.
The streaming media content is, for example, video, and the target streaming media content is the streaming media content that the user wants to obtain. The same streaming media content can correspond to a plurality of code rates, and each code rate has a corresponding streaming media file.
In step S204, when the streaming media file of the target streaming media content is not stored on the edge node to which the first terminal belongs, the original main index file of the target streaming media content is sent to the first terminal. The edge node to which the terminal belongs may be, for example, the edge node closest to the terminal.
The main index file comprises addresses of a secondary index file corresponding to a plurality of code rates respectively, and the secondary index file comprises addresses of the streaming media file corresponding to the corresponding code rates. In some embodiments, the primary index file and the secondary index file are in m3u8 format, and the streaming media content includes one or more Transport Stream (TS) slices. That is, the streaming media content may be organized based on HLS.
In step S206, the first terminal selects a first code rate according to the original main index file, and sequentially obtains a secondary index file and a streaming media file corresponding to the first code rate.
In some embodiments, the first terminal selects the first bitrate based on current network conditions and an original master index file.
The original primary index file still points to the address of the secondary index file in the cloud, such as the local address of the cloud server or cloud storage device. Therefore, the first terminal can acquire the second-level index file from the cloud end and acquire the streaming media file with the first code rate according to the second-level index file.
Therefore, under the condition that the current edge node does not store the streaming media file of any code rate version of the target streaming media content, the first terminal still obtains the streaming media file from the cloud.
In step S208, the secondary index file and the streaming media file of the target streaming media content and corresponding to the first bitrate are sent to the edge node to which the first terminal belongs to be stored.
In the secondary index file, the relative address or absolute address of the streaming media file can be recorded, and those skilled in the art can configure the relative address or absolute address as needed.
In some embodiments, if the relative address of the streaming media file is recorded in the secondary index file, the original secondary index file, that is, the secondary index file consistent with the cloud content, may be directly sent to the edge node. Under the condition that the relative positions of the secondary index file and the streaming media file are not changed, the streaming media file stored in the edge node can be indexed through the secondary index file stored in the edge node. The modification amount of the mode is small, and the processing efficiency is higher.
In some embodiments, if the absolute address of the streaming media file is recorded in the secondary index file, before the file is delivered to the edge node, the address of the streaming media file in the secondary index file corresponding to the first bitrate of the target streaming media content may be modified to the address of the corresponding streaming media file in the edge node, so as to send the modified secondary index file and the modified streaming media file to the edge node to which the first terminal belongs for storage. Thus, the streaming media file at the edge node can also be indexed through the secondary index file stored at the edge node. This approach may allow the edge node more flexibility in setting the relative storage locations of the secondary index file and the streaming media file.
In step S210, an acquisition request for the same target streaming media content from a second terminal belonging to the same edge node as the first terminal is acquired. At this time, the edge node already stores the secondary index file and the streaming media file corresponding to a certain bit rate of the target streaming media content.
The second terminal is any terminal belonging to the same edge node as the first terminal, and may be different from or the same as the first terminal.
In step S212, an address of a secondary index file corresponding to a first bitrate in an original primary index file of the target streaming media content is modified to an address of the secondary index file corresponding to the first bitrate in the edge node, and a modified primary index file is generated.
In some embodiments, storage information for each edge node may be recorded to quickly determine whether the primary index file needs to be modified.
In step S214, the modified main index file is sent to the second terminal, so that the second terminal sequentially obtains the secondary index file and the streaming media file according to the modified main index file.
Because the second terminal under the edge node requests the same streaming media content and the data related to the first bit rate of the streaming media content is already sent to the edge node, the main index file sent to the second terminal needs to be changed, so that the content needing to be acquired by the second terminal is preferentially acquired from the edge node when the second terminal has a copy in the edge node.
By the method of the embodiment, the streaming media content requested by the terminal can be stored in the edge node, so that when other terminals under the same edge node request the same streaming media content, the corresponding main index file is modified to guide the other terminals to preferentially acquire the streaming media content from the edge node under the condition that the streaming media files corresponding to the same code rate are required. Because the network quality of the terminals under the same edge node and in the same time period is generally similar, the service quality of most terminals requiring the same code rate can be improved, and a few terminals requiring other code rates can still obtain streaming media contents from the cloud. Therefore, the embodiment reduces the network load under the condition of not influencing the access delay of the streaming media content, fully improves the system efficiency and the user experience, and saves a large amount of edge node storage space.
In some embodiments, for the same streaming media content, if the edge node already stores the streaming media file with the first bitrate, but due to a network quality change or other reasons, other terminals under the same edge node request the streaming media file with other bitrate, the edge node may replace the related data with the first bitrate with the related data with the second bitrate. The streaming media communication method in this case is described below with reference to fig. 3.
Fig. 3 is a flow chart illustrating a streaming media communication method according to some embodiments of the invention. In this embodiment, the edge node already stores the second-level index file and the streaming media file corresponding to the first bitrate of the target streaming media content. As shown in fig. 3, the streaming media communication method of this embodiment includes steps S302 to S316.
In step S302, an acquisition request of the second terminal for the target streaming media content is acquired.
In step S304, an address of a secondary index file corresponding to a first bitrate in an original primary index file of the target streaming media content is modified to an address of the secondary index file corresponding to the first bitrate in the edge node, and a modified primary index file is generated.
In step S306, the modified primary index file is transmitted to the second terminal.
At this time, the main index file guides the second terminal to obtain the related content of the first code rate from the edge node and obtain the related content of other code rates from the cloud.
In step S308, an obtaining request of the second terminal to obtain a secondary index file corresponding to the second code rate of the target streaming media content is obtained.
In step S310, a secondary index file corresponding to the second code rate is sent to the second terminal, so that the second terminal can obtain the streaming media file according to the secondary index file corresponding to the second code rate.
In step S312, the second-level index file corresponding to the second bitrate and the corresponding streaming media file are sent to the edge node to which the second terminal belongs, and the edge node deletes the second-level index file and the streaming media file corresponding to the first bitrate of the target streaming media content.
In step S314, in response to an obtaining request of a third terminal that obtains the target streaming media content and belongs to the same edge node as the second terminal, an address of a secondary index file corresponding to a second bitrate in an original primary index file of the target streaming media content is modified to an address of the secondary index file corresponding to the second bitrate in the edge node, and a modified primary index file is generated.
At this time, the main index file guides the third terminal to obtain the related content of the second code rate from the edge node and obtain the related content of other code rates from the cloud.
The third terminal is any terminal belonging to the same edge node as the first terminal and the second terminal, and may be different from or the same as the first terminal and the second terminal.
In step S316, the modified main index file is sent to the third terminal, so that the third terminal sequentially obtains the secondary index file and the streaming media file according to the modified main index file.
By the method of the embodiment, under the edge node in which the related file with the first bitrate is stored, when other terminals request the related file with the second bitrate of the same streaming media content, the file in the edge node can be replaced by the related file with the second bitrate, so that the current state of the terminal under the edge node can be adjusted in time, more terminals can be provided with services accessed nearby, and the system efficiency is improved.
An embodiment of the invention is illustratively described below in conjunction with a specific application scenario. In this embodiment, terminal a and terminal B belong to the same edge node.
The terminal A initiates an acquisition request of a first video collection (ID is 1) of the documentary X to the cloud server. The cloud server sends an original main index file a.m3u8 to the terminal a, and the content of the main index file is shown in table 1. The code rates of the two levels of index files are 200000bps, 484444bps and 737777bps, and the relative URLs of the corresponding two levels of index files are gear1/index.m3u8, gear1/index.m3u8 and gear 1/index.m3u8.
TABLE 1
The current network condition of the terminal A is good, so that the highest code rate is selected to be 737777bps automatically, a secondary index file is obtained from gear3/index.m3u8, and TS fragments corresponding to 737777bps are downloaded from the cloud.
The cloud server pushes the secondary index file and the TS fragment corresponding to 737777bps to the edge node to which the terminal A belongs.
And the terminal B under the same edge node initiates an acquisition request for the same video. Because the file corresponding to 737777bps is stored in the edge node to which the terminal B belongs, the cloud server modifies the main index file a.m3u8 in real time, replaces the address of the secondary index file corresponding to the code rate 737777bps with the address of the secondary index file at the edge node (for example, http:// www.hlsnode01.cn/gear3/index.m3u8), and sends the modified a.m3u8 to the terminal B. The modified a.m3u8 is shown in table 2.
TABLE 2
When the network condition of the terminal B is good, the secondary index file of 737777bps is automatically requested according to the a.m3u8, so that the edge node can be accessed nearby and the secondary index file and the fragments can be obtained.
And if the bandwidth of the terminal B is reduced, the terminal B requests a file corresponding to the medium bitrate of 484444 bps. The address of the secondary index file corresponding to 484444bps still points to the cloud, so terminal B still downloads the corresponding content from the cloud at this time. Then, the cloud server records the latest code rate information of the video with the ID of 1 requested by the terminal under the edge node, and pushes the secondary index file and the fragment corresponding to the 484444bps code rate to the edge node. And emptying the secondary index file and the fragments corresponding to the 737777bps code rate by the edge node.
In some embodiments, when the content stored by the edge node is not accessed for a long time, the edge node may also empty the corresponding content and feed back to the cloud. A processing method for a file which has not been accessed for a long time is described below with reference to fig. 4.
Fig. 4 is an embodiment of a method of streaming media communication according to further embodiments of the present invention. As shown in fig. 4, the streaming media communication method of this embodiment includes steps S402 to S404.
In step S402, in response to the edge node deleting the streaming media file of the target streaming media content that is not accessed within the preset time period, the streaming media content and the bit rate corresponding to the deleted streaming media file are obtained.
In step S404, in response to an acquisition request of a terminal under an acquisition edge node for the target streaming media content, an original main index file of the target streaming media content is sent to the corresponding terminal. The method of the previous embodiment may then also be performed to backup the accessed content to the edge node.
By the method of the embodiment, the content stored by the edge node can be cleared when the content is not accessed for a long time, so that the available storage space of the edge node is increased.
