Description
Technical Field
The invention relates to the technical field of streaming media statistics, in particular to a method, a server and a system for identifying the stagnation of streaming media.
Background
With the popularization of the internet, the application range of network streaming media is wider and wider, and the streaming media can be understood as that a resource provider provides audio, video or multimedia files on an internet server in the form of data packets for a user to download and play. A significant portion of the traffic generated in the internet is caused by streaming media traffic.
The user can download the data packets of the streaming media files one by one in sequence, and the effect of playing the streaming media files at the edge can be achieved. However, due to the difference of the server or network environment used by the resource provider, the user may not play and pause the streaming media file smoothly when downloading the streaming media file on the internet. The experience of the user in using the streaming media service is reduced.
the pause of the streaming media can reflect the fluency of the streaming media playing at the terminal and the perception of the user using the streaming media service, the pause of the streaming media comprises pause times and pause time, the method for judging whether the streaming media is paused in the playing process at present is to determine the average downloading rate of the streaming media service, and when the average downloading rate is higher than a certain threshold value, the streaming media is determined not to be paused in the whole playing process.
however, the conventional scheme utilizes the user playing side, and records whether the Buffer is empty or not and records the pause at the player side. The player end is provided with IOS, Android, Flash and the like, and the playing pause rate is calculated through collecting the dotting logs.
the method is characterized in that the playing card pause rate is calculated by means of the data counting of the terminal, the implantation dotting and matching of the terminal are required, the uniform format access is included, the method has the defects that the unification and the inflexibility are unavailable, the control right of the terminal is on the hands of users as a CDN service manufacturer, the comprehensive coverage and the popularization as a universal scheme are unavailable, and the condition of each stage of live broadcast platform terminal cannot be controlled.
In addition, the downloading rate of the streaming media is in a fluctuating state, and the actual fluency in the playing process of the streaming media cannot be objectively reflected, for example, when the average downloading rate of the streaming media service in the whole playing process of the streaming media is higher than a threshold value, there may be a case where the downloading rate of the streaming media in a certain period of time is high, the playing is smooth, but the downloading rate in another period of time is low, the playing is stuck, and the number of times and time of the stuck times cannot be determined by the average downloading rate and the threshold value. The existing method for determining the pause of the streaming media cannot accurately reflect the fluency of the playing of the streaming media service.
if the relevant parameters such as the number of times of pause occurring when the streaming media is played can be effectively identified, the method can improve self service for a resource provider and provide important reference for improving the experience degree of the streaming media of a user.

Detailed Description
The technical solutions of the present application will be described in more detail below with reference to the accompanying drawings and embodiments.
It should be noted that, if not conflicted, the embodiments and the features of the embodiments can be combined with each other and are within the scope of protection of the present application. Additionally, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
in one configuration, a computing device for a streaming media kation recognition server to perform a kation calculation may include one or more processors (CPUs), input/output interfaces, a network interface, and a memory (memory).
the memory may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium. The memory may include one or more modules.
computer-readable media include both non-transitory and non-transitory, removable and non-removable storage media that can implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device.
example one
streaming media technology is now being used more and more widely, for example, online video, music, etc. are being applied. The resource provider of the streaming media provides streaming media files, such as audio, video or multimedia files, to the internet in the form of data packets for downloading by users, and the users can download the data packets in sequence to achieve the effect of viewing the files at the same time, thereby avoiding the waiting time for playing the files after the files are completely downloaded in the traditional file downloading mode.
However, when the user uses the service of the streaming media technology, the resource provider of the streaming media cannot accurately know the experience degree of the user using the streaming media technology. Generally, the online questionnaire is collected for users using streaming media technology, and the obtained data is neither accurate nor high in collection efficiency. Currently, a method for judging the Liu degree of the streaming media through a method for comparing the downloading rate of a user with a threshold exists. But as one of the important parameters for judging the user experience degree: whether the user plays the streaming media file is jammed or not is difficult to know from the network side.
to this end, an embodiment of the present invention provides a method for identifying a media jam, as shown in fig. 1, including:
s101, counting media data sent by a streaming media server in a preset period;
S102, obtaining media data missing in the receiving process of the client in the period;
S103, when the streaming media server determines that the media data missing in the period is larger than or equal to the size of the client cache, determining that the streaming media is played on the client.
The system of this embodiment performs statistics for a streaming media server or a client, preferably, performs statistics on a side of the streaming media server, and by monitoring a server that sends streaming media data, when the server that sends the streaming media data sends the media data to the client, determines media data (actual data sending amount) sent in a preset period in real time, and calculates media data (theoretical data sending amount) sent in the period by using a video attribute frame rate of the streaming media data; and acquiring the missing media data received by the client according to the difference value between the theoretical data sending quantity and the actual data sending quantity, and performing pause calculation to identify whether pause occurs when the client plays the streaming media data by comparing the missing media data with the size of the client cache according to the theoretical data sending quantity and the actual data sending quantity.
In the embodiment, the server records the missing media data in the preset period of the playing end, and when the missing media data is larger than the buffer Buff size of the client, the media data is recorded for one time. Under the condition that no client is matched, the jam condition of the current streaming media service can be effectively counted and calculated, the effect of monitoring and finding the jam condition of the current service is achieved, meanwhile, the produced quality of service jam data can evaluate whether the current streaming media service is healthy or not, and the method can be applied to quality tuning, service scheduling and other data-driven engineering projects such as intelligent diagnosis and troubleshooting.
for example, the following steps are carried out: the streaming media file is generally stored on the server and is divided into a plurality of data packets with sequences, and the client can download one data packet of the streaming media file from the server in sequence and play the streaming media file simultaneously. In this embodiment, data monitoring is performed on a server that stores a streaming media file. In the actual downloading process of the client, the client identifier or the user identifier carried by the client is used as a unique identifier to be distinguished from other clients or users, and in step S101, the server may perform statistics on the sent media data according to the identifier carried by the client when downloading the data packet.
In this embodiment, obtaining the missing media data received by the client in the period includes:
S201, calculating the sending media time length and the natural time length in the period by using the video attribute frame rate of the media data;
S202, recording the media data missing in the receiving process of the client in the period according to the difference value between the media sending time length and the natural time length, wherein the media sending time length represents the theoretical sending time length of the media data sent by the streaming media server, and the natural time length represents the actual sending time length of the media data sent by the streaming media server.
the sequence of the server sending the media data can be understood as the sequence of the client downloading and also the playing sequence of the streaming media file. Therefore, the situation that the streaming media is played in a pause state can be judged through the time length of the media data sent by the server.
the server calculates the sending media duration in the period by using the video attribute frame rate of the media data, wherein the video attribute frame rate of the media data can be obtained by a maximum likelihood estimation method according to the transmission frame rate of the streaming media, compares the sending media duration in the preset period with the natural duration (preset period duration), records the missing media data received by the client, for example, the statistical period is 3s, the actual data sending amount calculated by the media data sent by the server in the statistical period according to the video attribute frame rate can be played for 2s, at this time, the missing media data received by the client is lost as 1s, and jamming occurs when the media data cached by the client is less than 1 s. When the media data cached by the client is sufficient, the media data can be smoothly played.
In this embodiment, the statistical period may be generally set as a buffer duration of the viewed media data, for example, 3 seconds, and the memory and the computing capability of the server need to be considered.
in this embodiment, when it is determined that the pause occurs, the pause time may be determined according to the missing media data.
specifically, the difference between the media sending time length corresponding to the media data in the period and the natural time length is determined, and the difference is used as the pause time.
Example two
The embodiment determines the fluency of the media data playing for one or more periods according to the pause identified in the first embodiment.
Specifically, the media data playing fluency of one or more periods can be determined by one of the following methods:
The first method is as follows: counting the times of playing pause of accumulated media data in one or more periods, and determining the playing fluency according to the threshold range of the times of playing pause;
The second method comprises the following steps: counting the time of playing pause of accumulated media data in one or more periods, and determining the playing fluency according to the threshold range of the time of playing pause;
the third method comprises the following steps: and counting accumulated missing media data in one or more periods, and determining the playing fluency according to the threshold range of the missing media data.
in this embodiment, the playing fluency may be graded, the corresponding statistical values (including the number of times of pause, the time of pause, and the actual media data in this embodiment) are divided into a plurality of interval ranges, each range corresponds to one fluency grade, and the interval range in which the statistical value is located represents the playing fluency of the media data.
For example, the following steps are carried out: the playing fluency is divided into three levels, namely fluency, general and collapse, for example, the period is 3s, the statistical duration is 1 minute, and by taking the first mode as an example, fluency is set when the occurrence of the stuck times is less than 2 times, fluency is set when the occurrence of the stuck times is greater than or equal to 2 times, general is set when the occurrence of the stuck times is less than 5 times, and collapse is set when the occurrence of the stuck times is greater than or equal to 5 times. Counting the number of times of pause recognized in the first embodiment within 1 minute, determining the range (0-2, 2-5 and 5- ∞) of the section, and determining the corresponding playing fluency grade according to the counting result. Since 20 cycles are included in 1 minute of the statistical time length, a maximum of 20 calories occur according to the identification method of the first embodiment.
similarly, in the second mode, it is set that the flow is smooth when the karton time is less than 5s, the karton time is greater than or equal to 5s, the flow is normal when the karton time is less than 10s, and the collapse is performed when the karton time is greater than or equal to 10 s. Counting the accumulated time of the recognized pause times in the first embodiment within 1 minute, determining the range (0-5, 5-10 and 10- ∞) of the interval, and determining the corresponding playing fluency grade according to the counting result. Since the statistical time period is 1 minute, the maximum stuck time is 60 s.
if the third method is adopted, similarly, it is set that the missing media data is smooth when less than 5%, the missing media data is greater than or equal to 5%, and is normal when less than 10%, and the missing media data is broken when greater than or equal to 10%. And counting the accumulated lost media data within 1 minute, determining the range (0-5%, 5-10% and 10-100%) of the interval, and determining the corresponding playing fluency grade according to the counting result.
The counting of the playing pause times of the accumulated media data in one or more periods comprises the following steps:
When the times of the jamming are counted, if the situation of the jamming is continuously judged through the jamming calculation, counting the jamming judged under the situation as the same time of the jamming; alternatively, the first and second electrodes may be,
when the times of the jamming are counted, if the situation of the jamming is continuously judged through the jamming calculation, the times of the jamming which are judged to occur under the situation are respectively recorded.
for example, the following steps are carried out: if 6s appear stuck continuously, it can be marked as 1 stuck, and also can be marked as 2 stuck.
