Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the embodiment of the application, in order to solve the problem that the streaming media are damaged due to the fact that the same streaming media use different configuration parameters at different stages in the gray scale issuing process, a configuration parameter selection method for the streaming media is provided to ensure that the same streaming media use the same configuration parameters at different stages in the gray scale issuing process.
The configuration parameter selection method provided in the embodiment of the present application has a main application scenario as shown in fig. 1, and a system related to the application scenario mainly includes: a streaming media server 101 and a service processing server 102.
The streaming media server 101 is mainly used for acquiring a request of each stage of a multimedia stream sent by a client in a process of pushing or pulling the stream, and forwarding the request after processing the request. The service processing server 102 is mainly configured to generate, according to a request of a multimedia stream forwarded by the streaming media server, indication information for indicating selection of an original configuration parameter or a new configuration for the multimedia stream, and return the indication information to the streaming media server, so that the streaming media server selects the configuration parameter for the multimedia stream according to the indication information, and it is ensured that the multimedia stream uses the same configuration parameter in the whole process.
During the process of calculating the indication information of the multimedia stream, the service processing server 102 may call the data cached in the caching service 103 as needed.
Specifically, as shown in fig. 2, the service processing server 102 mainly performs the following processes in the process of selecting the configuration parameters of the multimedia stream:
In one embodiment, the identification parameters of the multimedia stream include: a user unique identification of the multimedia stream, a service name of the multimedia stream, and a name of the multimedia stream. It should be noted that, the identification parameter here refers to a parameter capable of uniquely identifying a multimedia stream, and any parameter or combination of multiple parameters capable of uniquely identifying a multimedia stream may be used as the identification parameter of the multimedia stream, and the selection of the identification parameter is not limited to the above listed cases.
In a specific embodiment, in order to ensure that the configuration parameters used by a multimedia stream at each stage are the same, the identification parameters are obtained from the request initially obtained in the push flow process or the pull flow process, and the processes from step 201 to step 203 are not performed for other requests in the push flow process or the pull flow process. The request initially obtained in the process of pushing or pulling may be a request which is obtained first and carries an identification parameter of the multimedia stream, for example, a publishing request (publish) in the process of pushing or a playing request (play) in the process of pulling.
For other requests, the streaming media server selects configuration parameters according to the stored indication information without recalculating the indication information by the service processing server, and the streaming media server directly selects the original configuration parameters for the multimedia stream under the condition that the indication information is not stored, so as to avoid that two configuration parameters occur in the whole process of the multimedia stream under the condition that the calculated indication information indicates to select new configuration parameters, so that the multimedia stream is damaged.
Specifically, for the stream pushing process, when acquiring a publishing request sent by the streaming media server, step 201 is executed to acquire the identification parameter from the publishing request. For the pull stream process, when acquiring the play request sent by the streaming media server, step 201 is executed to acquire the identification parameter from the play request.
It should be noted that, the representation value of the multimedia stream needs to satisfy the following two points: first, a multimedia stream is uniquely identified; second, the token values of the multimedia stream calculated for the same multimedia stream at different stages are unique. It is understood that the token value calculated according to the identification parameter of the multimedia stream is not limited to the specific manner of calculating the token value, as long as the above two points can be satisfied.
In a specific embodiment, a consistent hashing algorithm is used to calculate a characterizing value of a multimedia stream, and the specific process includes: and calculating a hash value of the identification parameter of the multimedia stream by adopting a consistent hash algorithm, obtaining a mapping value obtained by mapping the hash value onto a hash ring, and taking the mapping value as a characterization value for uniquely representing the multimedia stream.
In a specific embodiment, for a play request in a service processing server, a key (key value) dedicated to the play request is used to record an identification parameter carried in the play request, and a hash value is calculated according to the identification parameter recorded in the key. Similarly, for the issue request in the service processing server, a key dedicated to the issue request is used to record the identification parameter carried in the issue request, and the hash value is calculated according to the identification parameter recorded in the key. The playing request and the issuing request use the special keys respectively, so that the problems that under the condition of sharing the keys, the playing request is suddenly increased, the shared keys are greatly occupied by the playing request, the parameter identifiers of the issuing request in the keys cannot be obtained in time, and the new functions cannot be used for the issuing request in time can be avoided.
Wherein, the key format corresponding to the playing request is expressed as: play, user unique identification, user application type and user pull flow domain name. The key format corresponding to the issue request is expressed as: publish, user unique identification, user application type, and user plug-flow domain name.
In this specific embodiment, the gray level issue threshold belongs to a value range of the hash ring, and is not equal to the maximum value and the minimum value in the value range of the hash value.
The indication information is used for indicating that the original configuration parameters or the new configuration parameters are selected for the multimedia stream, and the gray level release threshold is a critical value used for selecting the original configuration parameters or the new configuration parameters in the gray level release.
Obtaining the indication information of the multimedia stream by comparing the representation value of the multimedia stream with the gray release threshold, specifically comprising: judging whether the representation value of the multimedia stream is smaller than the gray release threshold value or not; if yes, obtaining indication information for selecting new configuration parameters for the multimedia stream; otherwise, obtaining the indication information for selecting the original configuration parameters for the multimedia stream.
In a specific embodiment, a gray-scale function switch field is added in a task table of a service processing server and is represented as gray _ threshold, the gray-scale function switch field is turned off when the value is 0, and is turned on when the value is greater than 0, and the value when the value is greater than 0 is the upper limit value of the gray scale ratio, that is, the gray scale release threshold.
Assuming that a hash ring as shown in fig. 3 is used, the hash ring is composed of 100 points, that is, an integer with a value range of 1-100 is taken, if the value of the gray _ threshold is 20, it indicates that the indication information for selecting the new configuration parameter is obtained when the characteristic value is less than 20, and the indication information for selecting the original configuration parameter is obtained when the characteristic value is not less than 20; if the value of the gray _ threshold is 50, it indicates that the indication information for selecting the new configuration parameter is obtained when the characteristic value is less than 50, and the indication information for selecting the original configuration parameter is obtained when the characteristic value is not less than 50.
The grayscale release threshold may be stored in a key value as: { "gray _ threshold": 20} and the key value is saved in a cache (dit).
The obtained indication information may be represented as stream _ gray, and is used to indicate that a new configuration parameter is selected for the multimedia stream during the gray scale distribution process when the stream _ gray is 1, and is used to indicate that an original configuration parameter is selected for the multimedia stream during the gray scale distribution process when the stream _ gray is 0. If the value of the gray _ threshold is 20, setting the stream _ gray corresponding to the multimedia stream to be 1 when the representation value of the multimedia stream is less than 20, and setting the stream _ gray corresponding to the multimedia stream to be 0 when the representation value of the multimedia stream is not less than 20.
It should be noted that the manner of sending the corresponding relationship between the identification parameter of the multimedia stream and the indication information to the streaming media server is not limited, and a message carrying the corresponding relationship may be sent to the streaming media server separately, and the streaming media server extracts the corresponding relationship from the message and stores the corresponding relationship in the streaming media server, or stores the corresponding relationship in a specified cache.
In the embodiment of the application, according to the identification parameter and the gray level release threshold value of the multimedia stream, the indication information for indicating that the original configuration parameter or the new configuration parameter is selected for the multimedia stream is obtained, the identification parameter and the indication information are sent to the streaming media server, and the corresponding relationship between the identification parameter of the multimedia stream and the indication information is established, so that the streaming media server can obtain the indication information according to the identification parameter carried in the multimedia stream related message obtained at each stage, and select the configuration parameter for the multimedia stream according to the indication information, thereby ensuring that each stage of one multimedia stream in the gray level release process uses the same configuration parameter, and avoiding the problem that the multimedia stream is damaged due to different configuration parameters used at each stage.
Based on the same concept, as shown in fig. 4, the streaming media server 101 mainly performs the following processes in the configuration parameter selection process of the multimedia stream:
Specifically, the acquired request message of the multimedia stream may be any one of push stream and pull stream processes. For example, a distribution request, a play request, an update request (update), a distribution end request (publish _ done), and the like.
The request message of the multimedia stream carries a parameter capable of uniquely identifying the multimedia stream, such as a user unique identifier of the multimedia stream, a service name of the multimedia stream, a name of the multimedia stream, and the like. The parameter that can uniquely identify the multimedia stream here can be one parameter or a combination of parameters.
The identification parameter extracted here is identical to the identification parameter used when the instruction information is stored.
And step 403, acquiring indication information corresponding to the extracted identification parameter, wherein the indication information is used for indicating the multimedia stream to select the original configuration parameter or the new configuration parameter.
In a specific embodiment, the obtaining of the indication information corresponding to the extracted identification parameter includes: judging whether the stored corresponding relation between the identification parameters and the indication information contains the indication information corresponding to the extracted identification parameters; if yes, acquiring indication information corresponding to the extracted identification parameters from the corresponding relation; otherwise, generating the indication information corresponding to the identification parameter.
In the case that the correspondence does not include the indication information corresponding to the extracted identification parameter, the indication information corresponding to the identification parameter needs to be generated according to the type of the request message. The specific generation process comprises the following steps: judging whether the request message of the multimedia stream is a publishing request or a playing request; if yes, sending the request message of the multimedia stream to a service processing server, and obtaining indication information which is returned by the service processing server according to the request message of the multimedia stream and corresponds to the extracted identification parameter; otherwise, the indication information for indicating the selection of the original configuration parameter is used as the indication information corresponding to the identification parameter.
This ensures that the configuration is performed according to the configuration parameters indicated by the indication information at the initial stage of the push stream or the pull stream, and the configuration parameters indicated by the indication information are still used at the subsequent stage, thereby ensuring that the same configuration parameters are used for the entire multimedia stream. For the multimedia stream without indication information in the initial stage, namely, the gray scale issue does not exist in the initial stage, the original configuration parameters are directly selected for the multimedia stream, so that the condition that the gray scale issue does not exist in the initial stage of the multimedia stream is ensured, namely when the original configuration parameters are adopted, the original configuration parameters are also adopted subsequently.
In step 404, the configuration parameters indicated by the indication information are selected for the multimedia stream.
In the embodiment of the application, after the request message of the multimedia stream is obtained, the indication information corresponding to the identification parameter of the multimedia stream carried in the request message is obtained, and the original configuration parameter or the new configuration parameter is selected for the multimedia stream according to the indication information, so that the request messages belonging to different stages of the same multimedia stream can be ensured to correspond to the same indication information, the same configuration parameter is selected for the multimedia stream, the same configuration parameter is ensured to be used in different stages of the same stream in the gray level publishing process, and the problem that the multimedia stream is damaged due to different configuration parameters used in each stage is avoided.
In a specific embodiment, as shown in fig. 5, a process of processing a service processing server for issuing a request in a stream pushing process and a service processing server for playing a request in a stream pulling process is as follows:
507, carrying out step 516 after the gray scale upgrading does not exist and the processing is carried out according to the original flow;
step 511, no gray scale upgrading exists, and step 516 is executed after the processing according to the original flow;
step 514, returning indication information, which is used for indicating that the new configuration parameters are adopted, of the request end of the push stream or the pull stream, and is represented as Imds _ stream _ gray being 1, and executing step 516;
step 515, returning to the request end of the push stream or the pull stream, indicating information indicating that the original configuration parameters are adopted, which is denoted as ids _ stream _ gray is 0, and executing step 516;
step 516, the process ends.

at step 608, the process ends.
