In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application may be embodied in many other forms than those herein described, and those skilled in the art will readily appreciate that the present application may be similarly embodied without departing from the spirit or essential characteristics thereof, and therefore the present application is not limited to the specific embodiments disclosed below.
The terminology used in the one or more embodiments of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the one or more embodiments of the application. As used in one or more embodiments of the application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used in one or more embodiments of the present application refers to any or all possible combinations of one or more of the associated listed items.
It should be understood that, although the terms first, second, etc. may be used in one or more embodiments of the application to describe various information, these information should not be limited by these terms. These terms are only used to distinguish one type of information from another. For example, a first may also be referred to as a second, and similarly, a second may also be referred to as a first, without departing from the scope of one or more embodiments of the application. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "in response to a determination" depending on the context.
First, terms related to one or more embodiments of the present application will be explained.
TCP receive buffer: the core buffer area in the terminal for temporarily storing the data received from the server may be further divided into an audio buffer area and a video buffer area for the audio and video files.
First frame time: the time spent from the video playing of the user click to the video first frame rendering, the first frame time comprises the time spent by the links of video request, data buffering and decoding and rendering at the player level besides the time spent by the service side on the user click, page creation and rendering.
Katon rate: the playback event in which a jam occurs is a proportion of the total playback event.
Seek: and rapidly dragging the audio and video from the current position to the given position and playing the audio and video.
When the terminal downloads the audio and video from the server, the TCP creates a video buffer zone and an audio buffer zone, and the video buffer zone and the audio buffer zone are used together for data receiving by using network equipment of the terminal until the respective receiving buffer zones are filled, and the size of the video buffer zone and the audio buffer zone is fixed and is a larger fixed value by default by the system at present so as to facilitate the playing and use of the whole audio and video. At present, a method is also available for setting smaller audio buffer and video buffer when playing, and then using a simple growth strategy to make the audio buffer and video buffer grow to the maximum value.
However, in practical application, the code rate of the video is usually much larger than the audio code rate, and in the playing process, the video always competes with the video for bandwidth as long as the audio buffer area is not full, which results in slow downloading of the video which originally needs more bandwidth, and further causes the problems of slow loading of the first frame, even failure, playing of the video and the like. In addition, setting a larger audio buffer for the audio with smaller code rate may also lead to waste of traffic. Setting smaller audio buffer and video buffer during playing can optimize the first frame time and loading failure rate to a certain extent, but the growth strategy is too simple and lacks the regulation strategy, which may cause the increase of the playing card stop rate.
Based on this, in the present application, a network bandwidth allocation method is provided, and the present application relates to a network bandwidth allocation apparatus, a computing device, and a computer-readable storage medium, which are described in detail in the following embodiments one by one.
Fig. 1 shows a flowchart of a network bandwidth allocation method according to an embodiment of the present application, which specifically includes the following steps:
Step 102: and determining an audio buffer area and a video buffer area, wherein the audio buffer area is smaller than the video buffer area.
In practical application, a user wants to watch a certain audio/video, and needs to buffer the audio/video to a terminal for watching, at this time, the target audio/video specifically refers to the audio/video that the user wants to watch, in general, the video frame and the audio frame of the target audio/video are corresponding, the user uses the terminal to watch the target audio/video, and can click a play button on the terminal, the terminal sends an acquisition instruction of the target audio/video to the server, the server sends audio data and video data of the target audio/video to the terminal, the terminal receives the audio data and the video data by setting an audio buffer area and a video buffer area, specifically, buffers the audio data to the audio buffer area, buffers the video data to the video buffer area, and then buffers the audio data and the video data to the play buffer area, where the play buffer area is used for buffering the audio/video content that can be played directly in the player.
The user uses the terminal to send a caching instruction to the server, wherein the caching instruction specifically refers to an instruction for caching audio data and video data, and after receiving the caching instruction for a target audio and video, a frequency caching area and a video caching area are generated for the target audio and video, and the audio caching area and the video caching area are both TCP receiving caching areas.
The lengths of the audio buffer area and the video buffer area in the application are different, namely the audio buffer area is smaller than the video buffer area, and in particular, in order to meet the condition that audio and video do not get stuck during playing, the audio buffer area and the video buffer area need to meet the following conditions:
1, in order to ensure that the audio and video can be normally played, the audio and video needs to be cached for a certain time (frame number).
2, Because the audio code rate is usually smaller than the video code rate, in order to ensure that the downloaded frames of the two frames are as consistent as possible, the video buffer area is required to be ensured to be larger than the audio buffer area;
And 3, in order to reasonably allocate network bandwidth, the size of the audio buffer area cannot be too large, the audio buffer area is filled as soon as possible, the bandwidth is allocated to the video, and the synchronization of the audio and the video is ensured.
It should be noted that, in this step, the audio buffer and the video buffer may correspond to different stages of buffering the audio and video, in the playing stage, the initial audio buffer and the video buffer are determined according to the playing time of the target audio and video, and in the stage after playing, the audio buffer and the video buffer are buffers after being adjusted by the adjustment policy.
Based on this, in the play-up phase, an audio buffer and a video buffer are determined, including:
Determining the initial playing time length, the audio code rate and the video code rate of the target audio and video;
determining an initial audio buffer area based on the initial playing time length and the audio code rate;
And determining an initial video cache region based on the initial playing time length and the video code rate.
The initial playing duration is specifically to meet the requirement in the 1 st condition, and the initial playing duration may be set to be 2 seconds. The audio code rate specifically refers to the code rate of audio in the target audio and video, the video code rate specifically refers to the code rate of video in the target audio and video, and in practical application, after the target audio and video are determined, the audio code rate and the video code rate can be directly obtained based on the target audio and video.
After the initial playing time length, the audio code rate and the video code rate are determined, an initial audio buffer area can be determined according to the initial playing time length and the audio code rate, an initial video buffer area is determined according to the initial playing time length and the video code rate, specifically, the size of the initial audio buffer area can be obtained by multiplying the initial playing time length and the audio code rate, and the size of the initial video buffer area can be obtained by multiplying the initial playing time length and the video code rate. For example, the initial play time is 5 seconds, the audio rate is 50K, and the video rate is 200K, based on which it can be determined that the initial audio buffer is set to 250K and the initial video buffer is 1000K.
In the subsequent operation, the audio buffer area and the video buffer area can be adjusted according to the corresponding buffer area adjustment strategy, and the adjusted audio buffer area and video buffer area are acquired.
Step 104: and caching the audio data of the target audio and video into the audio cache region, and caching the video data of the target audio and video into the video cache region.
After the audio data cache area and the video cache area of the target audio and video are determined, the audio data and the video data of the target audio and video can be received, the audio data are cached in the audio cache area, and the video data are cached in the video cache area.
Step 106: and acquiring the audio cache information of the audio cache region, and acquiring the playing cache information corresponding to the target audio and video and the video cache information of the video cache region.
In the process of caching audio data and video data, monitoring audio cache information of an audio cache region, wherein the audio cache information specifically refers to information of the audio data cached in the audio cache region, and can include audio cache duration, audio cache rate of the audio cache region and the like.
By acquiring the audio buffer information of the audio buffer area, the network bandwidth is conveniently distributed according to the audio buffer information, so that the audio bandwidth and the video bandwidth are dynamically adjusted in the process of buffering the audio data and the video data.
In practical application, audio data is cached to an audio cache region, video data is cached to a video cache region, a playing cache region is further arranged in the terminal, target audio and video data for playing is cached in the playing cache region, namely, the audio data of a target frame is obtained from the audio cache region, the video data of the target frame is obtained from the video cache region, the audio data and the video data corresponding to the target frame are combined to generate audio and video data, the audio and video data is cached to the playing cache region, and the target audio and video data in the playing cache region can be directly used for playing by a player.
The playing buffer information of the target audio and video in the playing buffer area is obtained, and specifically, the playing buffer information may include playable duration of the target audio and video, playing buffer rate of the playing buffer area, and the like.
The video buffering information specifically refers to information of video data buffered in the video buffering area, and may include a video buffering duration, a video buffering rate of the video buffering area, and the like.
In the process of caching the video data and the audio data of the target audio and video, the playing cache information in the playing cache area and the video cache information in the video cache area can be obtained in real time, and the sizes of the video cache area and the audio cache area can be adjusted in an assisted mode according to the playing cache information and the video cache information.
Step 108: and distributing video bandwidth and audio bandwidth for the target audio and video according to the audio cache information.
After the audio buffer information is obtained, the audio bandwidth and the video bandwidth can be dynamically adjusted in real time according to the specific condition of the audio buffer information, wherein the audio bandwidth specifically refers to the bandwidth allocated for buffering the audio data, the video bandwidth specifically refers to the bandwidth allocated for buffering the video data, in practical application, the total bandwidth of the terminal is fixed, and the audio bandwidth and the video bandwidth are determined from the total bandwidth.
In an embodiment of the present application, further, the audio buffer information includes an audio buffer rate, and accordingly, video bandwidth and audio bandwidth need to be allocated to a target audio and video according to the audio buffer rate, specifically, video bandwidth and audio bandwidth need to be allocated to the target audio and video according to the audio buffer information, including:
adjusting video bandwidth to be equal to audio bandwidth under the condition that the audio buffer rate is smaller than or equal to a preset audio threshold, wherein the preset audio threshold is determined according to the audio buffer area;
and adjusting video bandwidth to be larger than audio bandwidth under the condition that the audio buffer rate is larger than the preset audio threshold value.
The audio buffer rate specifically refers to a buffer ratio of audio data in an audio buffer, for example, the size of the audio buffer is 400K, and if the buffered audio data has 200K, the audio buffer rate is 50%; if the size of the audio buffer area is 500K, the buffered audio data has 450K, and the audio buffer rate is 90%.
The preset audio threshold specifically refers to a threshold of audio data in an audio buffer zone, which is preset, if the audio buffer rate in the audio buffer zone is greater than the preset audio threshold, it is indicated that the data in the audio buffer zone is saturated at this time, and the audio bandwidth for buffering the audio data can be no longer allocated for the data; if the audio buffer rate in the audio buffer is smaller than or equal to the preset audio threshold, it is indicated that there is space in the audio buffer for buffering the audio data at this time, and the same bandwidth can be allocated for the audio data and the video data. Specifically, the preset audio threshold may be set higher, for example, 99%, 99.5%, etc., and the specific setting of the preset audio threshold is based on practical application.
In a specific embodiment of the present application, taking the preset audio threshold value as 99% as an example, the audio buffer rate of the audio buffer area is obtained to be 60%, and if the audio buffer rate is smaller than the preset audio threshold value, it can be determined that the audio buffer area is not filled yet, and if the audio bandwidth is the same as the video bandwidth.
In another specific embodiment provided by the application, taking the preset audio threshold value as 99% as an example, the audio buffer rate of the audio buffer area is obtained to be 99.3%, and at the moment, the audio buffer rate is larger than the preset audio threshold value, the audio buffer area can be determined to be filled, and more network bandwidth is allocated to the video bandwidth, so that more network traffic can be obtained for the video data, and the buffering of the video data is quickened.
By monitoring the audio buffer information (audio buffer rate) in the audio buffer area, the video bandwidth and the audio bandwidth can be dynamically adjusted, more bandwidth resources can be allocated to the video data under the condition that the audio buffer rate of the audio data in the audio buffer area is enough, the video buffer efficiency is improved, and the waste of network bandwidth is reduced.
It should be noted that, at this time, the audio buffer and the video buffer are not the maximum values, and the buffered audio data and video data are not all the data of the target audio and video, so that the sizes of the audio buffer and the video buffer also need to be dynamically adjusted. So that the audio buffer area and the video buffer area can buffer the audio data and the video data of the target audio and video.
Step 110: and determining a target cache region adjustment strategy according to the playing cache information and the video cache information, and adjusting the audio cache region and the video cache region based on the target cache region adjustment strategy.
The target buffer adjustment policy specifically refers to a buffer size adjustment policy determined according to current playing buffer information and video buffer information, where the adjustment policy is used to adjust the size of an audio buffer and the size of a video buffer. And adjusting the audio buffer area and the video buffer area according to the target buffer area adjusting strategy.
In the method provided by the application, the audio buffer area and the video buffer area are not mechanically increased according to time, but are dynamically and adaptively adjusted according to the current playing buffer information and video buffer information.
Specifically, the playing cache information comprises a cache playing time length, and the video cache information comprises a video cache rate;
Determining a target buffer adjustment strategy according to the play buffer information and the video buffer information, including:
under the condition that the playing cache information meets the preset playing condition, determining the target cache area adjusting strategy as the maximum adjusting strategy;
determining a target cache region adjustment strategy as an increase adjustment strategy under the condition that the play cache information does not meet a preset play condition and the video cache rate is greater than or equal to a first preset video threshold value;
Determining a target cache region adjustment strategy to be a maintenance adjustment strategy under the condition that the play cache information does not meet a preset play condition, and the video cache rate is larger than a second preset video threshold and smaller than the first preset video threshold;
And determining the target cache region adjustment strategy as a reduction adjustment strategy under the condition that the play cache information does not meet the preset play condition and the video cache rate is smaller than or equal to the second preset video threshold value.
In practical application, the playing cache information comprises cache playing time length, playing cache rate and the like; the video cache information comprises a video cache rate, and the cache playing time length specifically refers to the playing time length of a target audio/video supported to be played in a playing cache region, for example, if the playing cache region is cached with the target audio/video for 8 minutes, the playing time length of the cache is 8 minutes. The play buffer rate represents the buffer ratio of the audio and video in the play buffer area.
The video buffer rate is the same as the audio buffer rate described above, and is used to represent the buffer ratio of video data in the video buffer. The calculation method of the video buffer rate refers to the calculation method of the audio buffer rate in the above embodiment, and will not be described herein.
Furthermore, the adjustment strategy of the buffer area is primarily judged according to the playing buffer information, if the playing buffer information meets the preset playing condition, the current network speed of the user is better, the network bandwidth is not required to be planned, and the video buffer area and the audio buffer area can be directly adjusted to the maximum.
Specifically, the preset playing condition can be confirmed from two dimensions, namely, a playing time length and a playing buffer rate, if the playing time length is longer than the preset playing time length and the playing buffer rate is greater than a preset buffer threshold, it can be determined that the playing buffer information meets the preset playing condition, for example, taking the preset playing time length as 30 seconds and the preset buffer threshold as 50%, at this time, the playing buffer information is in the buffer playing time length of 2 minutes and the playing buffer rate as 60%, and then it is indicated that the playing buffer information meets the preset playing condition at this time, and it can be determined that the target buffer adjustment policy is the maximum adjustment policy.
In another embodiment provided in the present disclosure, if the playing buffer information does not meet the preset playing condition, that is, the playing time length of the buffer is less than or equal to the preset playing time length or the playing buffer rate is less than or equal to the preset buffer threshold, the network condition of the user is indicated to be general. And because the video code rate is higher than the audio code rate, the consumption of the video data is faster, and the current network condition of the terminal can be further judged through the video buffer rate in the video buffer zone.
Specifically, if the playing buffer information does not meet the preset playing condition and the video buffer rate is greater than or equal to the first preset video threshold, which indicates that the network state is good at this time, the size of the video buffer area and the audio buffer area can be further increased, so that more video data and audio data are stored, that is, the target buffer area adjustment strategy at this time is an increase adjustment strategy.
If the playing buffer information does not meet the preset playing condition and the video buffer rate is greater than the second preset video threshold and smaller than the first preset video threshold, which indicates that the network state is poor at this time, the video data in the video buffer area is difficult to support the playing of the target audio and video, and the audio data needs to be reduced as much as possible to occupy the network bandwidth and allocate more network bandwidth resources for buffering the video data, so that the target buffer area adjustment strategy at this time can be determined to be the maintenance adjustment strategy.
If the playing buffer information does not meet the preset playing condition and the video buffer rate is smaller than or equal to the second preset video threshold, the user is informed that the Seek operation (the process of rapidly dragging the audio and video from the current position to the given position and playing) or the network speed is suddenly reduced is performed on the target audio and video. At this time, the length of the audio buffer needs to be reduced to limit the competing network speed of the audio data and the video data, i.e. the target buffer adjustment strategy is determined to be the reduction adjustment strategy.
After the target buffer adjustment strategy is determined, the audio buffer and the video buffer corresponding to the target audio and video can be adjusted according to the target buffer adjustment strategy. The following describes the adjustment of the audio buffer and the video buffer with four embodiments for each buffer adjustment strategy.
In one embodiment of the present application, when the target buffer adjustment policy is the maximum adjustment policy, adjusting the audio buffer and the video buffer based on the target buffer adjustment policy includes:
determining the maximum value of an audio buffer area and the maximum value of a video buffer area based on the target audio and video;
And adjusting the audio buffer area to the maximum value of the audio buffer area, and adjusting the video buffer area to the maximum value of the video buffer area.
The maximum value of the audio buffer area specifically refers to the maximum buffer value required by the audio buffer area, and the maximum value of the video buffer area specifically refers to the maximum buffer value required by the video buffer area. Under the condition that the target buffer area adjustment strategy is the maximum adjustment strategy, the fact that the current network speed of the user is better at the moment is indicated, and the video buffer area and the audio buffer area are directly adjusted to the corresponding maximum values.
It should be noted that, also because the audio code rate and the video code rate are different, the maximum value of the audio buffer area and the maximum value of the video buffer area can be determined based on the code rate and the video code rate, so that unnecessary network bandwidth waste is avoided, and the audio data in the audio buffer area and the video data in the video buffer area can support the same playing time length. Specifically, determining the maximum value of the audio buffer area and the maximum value of the video buffer area based on the target audio and video includes:
Determining the total playing time length, the audio code rate and the video code rate of the target audio and video;
Determining the maximum value of an audio buffer area according to the total playing time length and the audio code rate;
and determining the maximum value of the video buffer area according to the total playing time length and the video code rate.
