Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. 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 invention.
In an embodiment of the present invention, a method for adjusting a bit rate of streaming media in a live network is provided, including: and synchronously adjusting the stream pushing bit rate of the live broadcast room according to the real-time popularity condition of the live broadcast room. Referring to fig. 1, the method specifically includes: s11, acquiring the correlation between the live broadcast room popularity value and the stream pushing bit rate; s12, confirming the real-time popularity value of the live broadcast room; and S13, adjusting the push stream bit rate of the live broadcast room in real time according to the confirmed popularity value of the live broadcast room and the association relation.
Specifically, the live broadcast room is a multifunctional network live broadcast platform integrating audio, video and interaction links into a whole by means of a network live broadcast platform, utilizing the internet and advanced multimedia communication technology and establishing the network live broadcast platform, enterprises or individuals can directly perform comprehensive communication and interaction of voice, video and data on line, and generally, at least one main broadcast is arranged in one live broadcast room to host communication and interaction of the live broadcast room. Meanwhile, some network live broadcast platforms set a popularity value for each live broadcast room according to a certain rule in order to reflect the popularity of the live broadcast room, wherein the popularity value is generally related to the number of audiences currently participating in the live broadcast room, the popularity value is higher when the number of audiences currently participating in the live broadcast room is larger, and the popularity value is lower when the audience currently participating in the live broadcast room is larger, otherwise.
When the network is broadcast directly, the main broadcast in the live broadcast room can interact with the audience in real time, the streaming media such as video and audio in the live broadcast room are all transmitted to the audience in real time in a streaming mode, and the process of transmitting the streaming media such as video and audio to the audience in real time in the streaming mode in the live broadcast room can be called as stream pushing in the live broadcast room. The transmission speed of video and audio data in the transmission process is usually expressed by bit rate, and the bit rate of streaming media in the transmission process is called the push streaming bit rate of a live broadcast; in general, the bit rate of streaming media delivered to viewers in real time is stable. The bit rate is the number of bits (bits) transmitted Per second, and the unit is bps (bit Per second), which is an index for indirectly measuring the quality of video and audio, and meanwhile, the higher the bit rate is, the faster the data transmission speed is; therefore, the quality of audio and video files is often measured by using the bit rate, and the higher the bit rate, the higher the quality of the corresponding audio and video files.
In this embodiment, before the live broadcast is performed in the live broadcast room, the relationship between the popularity value and the streaming bitrate in the live broadcast room may be set by the server.
In the embodiment, when the live broadcast is carried out in the live broadcast room, the stream pushing bit rate of the live broadcast room is synchronously adjusted according to the real-time popularity condition of the live broadcast room. Specifically, the server confirms the popularity value of the current live broadcast room in real time, and then adjusts the stream pushing bit rate of the live broadcast room according to the popularity value and the incidence relation. For a live broadcast room with high popularity, the popularity level is also high, and the stream pushing bit rate of the live broadcast room is adjusted to be high, so that the quality of videos and audios received by audiences of the live broadcast room is higher, and better user experience is obtained; for a live broadcast room with low popularity, the bit rate of the push stream of the live broadcast room is adjusted to be low, the bit rate is the bit quantity of continuous audio or video played in unit time, in this sense, the bit rate is equivalent to bandwidth consumption, and the adjustment of the bit rate is to reduce the consumption of the broadband, so that the broadband cost of the live broadcast is reduced.
In the embodiment, the stream pushing bit rate of the live broadcast room is synchronously adjusted according to the real-time popularity condition of the live broadcast room, and the stream pushing bit rate of the live broadcast room is increased for the live broadcast room with a high popularity value and more audiences, so that the high-quality experience of most audiences in watching the network live broadcast is ensured; for the live broadcast room with lower popularity value and less audiences, the stream pushing bit rate of the live broadcast room is reduced, which is beneficial to reducing the broadband cost of live broadcast.
Based on the above embodiment, the obtaining of the association relationship between the live room popularity value and the stream pushing bit rate includes: setting the popularity grade of the subareas of the live broadcast rooms; adding a partition identifier to the live broadcast room; and determining the push stream bit rate of the broadcast in the live broadcast room according to the popularity grade of the partition corresponding to the partition identification of the live broadcast room. Acquiring the incidence relation between the live broadcast room popularity value and the stream pushing bit rate comprises the following steps: setting the incidence relation between the popularity value of the partition and the plug flow bit rate, and setting the incidence relation between the popularity value of the partition corresponding to the partition identification and the partition identification of the live broadcast room and the plug flow bit rate as a one-to-one correspondence relation; and acquiring the association relation between the popularity value and the stream pushing bit rate of the live broadcast room according to the partition identification of the live broadcast room.
Specifically, the live broadcast rooms can be divided into different partitions according to the historical popularity of the anchor broadcast in the live broadcast rooms; the live broadcast may also be partitioned into different partitions, such as a game live partition, a sports live partition, a presentation partition, etc., depending on the content being played in the live broadcast. The server sets different popularity grades for different partitions, and determines the stream pushing bit rate of broadcasting according to the popularity grade of the partition when the broadcasting is performed in the live broadcast room of the partition; the specific method for partitioning the live broadcast room is that a partition identifier is added to the live broadcast room, and the partition identifier of the live broadcast room is associated with the popularity grade of the corresponding partition.
According to the characteristics of the partitions, setting the association relationship between the popularity value and the plug flow bit rate of each different partition, for example, for the live broadcast content corresponding to some partitions, the requirement on the video or audio quality is not high, and then the association relationship can be set to be a higher popularity value corresponding to a lower plug flow bit rate; the live broadcasting room added with the partition identification has a one-to-one correspondence relationship with the correlation relationship between the popularity value and the plug flow bit rate of the corresponding partition, and then the correlation relationship between the popularity value and the plug flow bit rate of the live broadcasting room can be obtained according to the partition identification, and the correlation relationship between the popularity value and the plug flow bit rate of the live broadcasting room is the same as the correlation relationship between the popularity value and the plug flow bit rate of the partition to which the live broadcasting room belongs, so that the consumption of the bandwidth of the partition is reduced as a whole.
Wherein, the incidence relation is a step incidence relation; for example, the push stream bit rate corresponding to the popularity value of 0-100 is defined as 50bps, the push stream bit rate corresponding to the popularity value of 100-.
In this embodiment, the foregoing steps may be implemented by the following specific operations, after logging in a background service (WebBackstageServer), a background administrator (Administrators) respectively sets association relationships between popularity values and streaming bit rates of different partitions (partitions), partitions a live broadcast room according to content characteristics of a broadcast of the live broadcast room, and adds a Partition identifier (partitionnark) of the Partition to the live broadcast room in the same Partition. After the partition identifier is added successfully, the corresponding relation between the partition identifier and the correlation between the popularity value and the pushed stream bit rate of the partition is simultaneously maintained in a popularity intermediate table (ArtitionRateNexus).
In the embodiment, the relationship is respectively set for the popularity value and the streaming bit rate of different partitions, so that the live broadcast rooms in different partitions have different relationships, and the streaming bit rate of the live broadcast room can be more flexibly adjusted according to the content played by the live broadcast room.
Based on the above embodiment, referring to fig. 2, confirming the real-time popularity value of the live broadcast room includes: acquiring the popularity values of all live broadcast rooms at intervals of first preset time; and adding the live broadcast room with the change amplitude of the popularity value meeting the first preset condition into the monitoring list. The step of confirming the real-time popularity value of the live broadcast room comprises the following steps: acquiring the popularity value of the live broadcast room in the monitoring list again at intervals of second preset time; judging whether the change amplitude of the popularity value of the same live broadcast room before and after a second preset time meets a second preset condition or not; and confirming the obtained popularity value of the live broadcast room meeting the second preset condition as the real-time popularity value of the live broadcast room.
Specifically, after the live broadcast is started, the live broadcast is performed at the started push bit rate, and the specific implementation method is described in the above embodiment, which is not described herein again; before adjusting the bit rate of the streaming media output by the live broadcast room in real time, a foreground monitor is established first, and the foreground monitor monitors the human value of the live broadcast room in the subarea. A partition monitoring service (PartitionMonitor) is added in a front-end service (WebReceptionserver), a live broadcast room added with a partition identifier is monitored for a human value, the foreground monitoring defaults to acquire the human value (PopularityValue) of the live broadcast room in the current partition through a human value change interface (Popularitydynamic) provided in the foreground service, and the current human value of the live broadcast room is acquired by taking the acquired human value detail of the live broadcast room as a basic condition.
The method comprises the steps of refreshing a popularity value of a live broadcast room every a first preset time (for example, 30 minutes), monitoring the live broadcast room reaching a first preset condition, wherein the first preset condition can be that the popularity value change amplitude of the same live broadcast room exceeds a preset percentage, matching a system time (system.date) carried by a foreground service with a monitoring time (monitor time) set by a background service, executing a popularity value acquisition action (PolargityObtain) every the first preset time, storing the acquired popularity value of the live broadcast room into a popularity list (PopulgityObtain L ist), screening popularity values in the popularity list, marking (MarkRoom) the live broadcast room reaching the first preset condition, bringing the marked live broadcast room monitoring list (PopulgityObtain L) into the live broadcast room, and re-acquiring the first preset time of the live broadcast room.
Continuously monitoring the live broadcast rooms brought into the live broadcast room monitoring list, and performing traversal matching on the human value of the live broadcast rooms in the live broadcast room monitoring list in a timing mode through the service self-contained system time length of the foreground, namely refreshing the human value of the live broadcast rooms brought into the live broadcast room monitoring list again after a second preset time (for example, 10 minutes) is separated through foreground service, and if the change range of the human value of the same live broadcast room before and after the second preset time meets a second preset condition; confirming the popularity value of the re-acquired live broadcast room meeting a second preset condition as a real-time popularity value of the live broadcast room, determining the stream pushing bit rate of the live broadcast room according to the real-time popularity value, if the second preset condition is not met, indicating that the popularity value of the live broadcast room is unstable, not adjusting the stream pushing bit rate of the live broadcast room, deleting the live broadcast room from a monitoring list, and executing the popularity value acquisition action on the live broadcast room again at intervals of first preset time; the second preset condition is that the change range of the popularity value of the same live broadcast room before and after the second preset time does not exceed a preset percentage.
The server automatically determines the push stream bit rate of the live room with the popularity value. The foreground service transmits the ID of the live broadcast room reaching the regulation bit rate standard to the background service through an interface (pushFlowInterface) provided by the background service for the live broadcast room reaching the regulation bit rate standard in the live broadcast room monitoring list, and the background service correspondingly regulates the push stream bit rate of the live broadcast room reaching the regulation bit rate standard according to the ID of the live broadcast room and the incidence relation between the popularity value and the push stream bit rate set in the popularity intermediate table.
In the embodiment, the live broadcast room needing important monitoring is screened through the first preset time, and the popularity value of the live broadcast room is confirmed through the second preset time, so that the burden of the server can be reduced, the stream pushing bit rate of the live broadcast room can be adjusted under the condition that the popularity value of the live broadcast room reaches a stable state, and the influence caused by the adjustment of the stream pushing bit rate of the live broadcast room due to the contingency is reduced.
Based on the above embodiment, the method further comprises: the upper limit value of the push stream bit rate of the live broadcast room is set, and the upper limit value of the number of people in the live broadcast room reaching the upper limit value of the bit rate is increased.
Specifically, the bit rate is the number of bits for playing continuous audio or video per unit time, which corresponds to the amount of bandwidth consumption; meanwhile, the higher the bit rate, the higher the quality of the corresponding audio and video streams. A choice can be made between bandwidth consumption and the quality of audio and video files, so that the bandwidth consumption can be relatively small, and the quality of audio streams and video streams can be relatively high. The quality of the audio stream and the video stream at the bit rate upper limit value is high, and the upper limit of the number of people in the live broadcast room can be increased in the live broadcast room with the bit rate, so that more users can experience high-quality live broadcast service.
According to the embodiment, the upper limit value of the stream pushing bit rate of the live broadcast room is limited, and the upper limit value of the number of people in the live broadcast room is increased, so that on one hand, the consumption of bandwidth can be effectively limited, and on the other hand, more users can obtain high-quality live network experience.
As still another embodiment of the present invention, referring to fig. 3, there is provided a bit rate adjustment apparatus for streaming media in live network, including: an obtaining module 31, a confirming module 32 and an adjusting module 33, wherein:
the obtaining module 31 is configured to obtain an association relationship between a popularity value and a streaming bit rate of a live broadcast room;
the confirming module 32 is used for confirming the real-time popularity value of the live broadcast room;
the adjusting module 33 is configured to adjust the streaming bitrate of the live broadcast room in real time according to the confirmed popularity value of the live broadcast room and the association relationship.
Specifically, before the live webcast is performed in the live webcast room, the obtaining module 31 obtains the association relationship between the popularity value of the live webcast room and the streaming bit rate, and preferably, the popularity value of the live webcast room is set to be higher, and the corresponding streaming bit rate is set to be higher.
When the live webcast is performed in the live webcast room, the confirmation module 32 determines the popularity value of the live webcast room in real time, and then the adjustment module 33 adjusts the streaming bit rate of the live webcast room according to the popularity level and the association relationship. For a live broadcast room with high popularity, the popularity level is also high, and the stream pushing bit rate of the live broadcast room is adjusted to be high, so that the quality of videos and audios received by audiences of the live broadcast room is higher, and better user experience is obtained; for a live broadcast room with low popularity, the bit rate of the stream pushed by the live broadcast room is adjusted to be low, the bit rate is the bit quantity of continuous audio or video played in unit time and is equivalent to the bandwidth consumption, and the adjustment of the bit rate is to reduce the consumption of the broadband, so that the broadband cost of network live broadcast is reduced.
In the embodiment, the acquisition module acquires the correlation between the popularity level and the streaming bit rate of the live broadcast room, the confirmation module confirms the real-time popularity value of the live broadcast room, and the adjustment module adjusts the streaming bit rate of the live broadcast room in real time, so that the live broadcast room with a higher popularity value is adjusted to a higher streaming bit rate, thereby ensuring the high-quality experience of watching the live broadcast of a network by most audiences; for the live broadcast room with lower popularity value, the stream pushing bit rate is reduced, which is beneficial to reducing the broadband cost of network live broadcast.
