In this embodiment, the number of users associated with the transport stream media file is not limited.
102. And sending the monitoring data to a log center so that the control center outputs the monitoring data counted by the log center.
And sending the monitoring data information collected by the streaming media server to a log center. The streaming media file realizes the real-time property of transmission through the streaming media server. The streaming media server is divided into different types according to different transmission protocols adopted in the file transmission process. Illustratively, if the RTMP (real time messaging protocol) transmission protocol is used, the CRTMPSEVER server is used. If an HLS (http live streaming, streaming media based on hypertext link protocol) transport protocol is adopted, the NGINX server is used. The same transport protocol, including multiple types of servers. In this embodiment, the specific type of the server is not limited.
And the log center receives the monitoring data and counts the monitoring data. Selecting the monitoring data of the same client IP from the monitoring data, and analyzing the transmission condition of the streaming media file of the client; selecting the same server IP, and analyzing the streaming media file transmission condition of the server; the same streaming media file, i.e. the same stream ID, is selected, and whether the streaming media file is complete or not is analyzed.

Compared with the prior art, the embodiment of the invention can monitor the transmission of the streaming media file data in the transmission process of the streaming media file, and monitor and record the data transmission state of the streaming media file in real time.
Further, as a refinement of the method shown in fig. 1, another method for monitoring transmission of a streaming media file is further provided in the embodiments of the present invention, as shown in fig. 2, where the method includes:
201. and collecting monitoring data generated in the uploading process of the streaming media file.
Streaming media, which is "while" streaming media files are uploaded by a streaming media file provider, viewers can view the synchronized streaming media files. The uploading streaming media file is a part of the transmission process of the streaming media file, is a source of the streaming media file, and needs to acquire monitoring data generated in the uploading process of the streaming media file.
When the streaming media file is uploaded on the client, monitoring data of the client are collected, wherein the monitoring data of the client comprise uploading rate, client internet protocol address IP, server IP, stream ID and frame loss times. The upload rate refers to the speed of the streaming media file per unit time in the upload process, and the rate is usually KB/sec or KB/min. In this embodiment, the unit of the upload rate is not limited. The client IP and the server IP refer to address information of the client or the server, and may search a corresponding actual geographic location corresponding to the address information. Stream ID, which refers to the encoding of a streaming media file, represents a streaming media file. The encoding of the stream ID may be written according to a certain encoding rule or may be randomly generated. The stream ID may be encoded by numbers, by letters, or by both numbers and letters. In this embodiment, the encoding method of the stream ID is not limited, and the encoding composition of the stream ID is not limited.
In the process of uploading the streaming media file, the streaming media file is divided into a plurality of data frames, and the data frames are transmitted one by one. Due to the influence of network conditions, transmission paths, server performance, etc., a frame loss phenomenon may occur during the transmission of data frames. According to the identification information contained in the data frame, it is possible to determine whether there is a frame loss, where the frame loss occurs, and how many frames are lost for the whole streaming media file.
In the process of uploading the streaming media file, the data is regularly monitored and sent to the server through the configuration file of the streaming media platform for collecting the uploading information. And recording the uploading rate, the client Internet protocol address IP, the server IP, the stream ID and the frame loss times in the monitoring data.
And when receiving the streaming media file uploaded by the client, judging whether a key frame exists. The key frame is the key information in the multimedia file. The key frame is determined when the streaming media file is split, and may be a key part in the streaming media file, or carry key information of the streaming media file, or define a key frame at intervals of a certain number of data frames. If there is no key frame in a certain time interval, it indicates that the key frame is lost in the transmission process of the streaming media file, the streaming media file uploaded by the client is incomplete, and there is a playing defect. Illustratively, the streaming media file is a video file, the video is a teaching video, and a video frame is a writing on a blackboard written in the teaching process. The picture is divided into two data frames, one is background information of the picture, and the other is text information of the picture, and obviously the text information is key content of the picture, so the text information is defined as a key frame. In this embodiment, the determination method of the key frame is not limited.
Monitoring data generated in the uploading process of the streaming media file is collected and recorded in a log mode so as to further process the monitoring data.
202. And sending the monitoring data to a log center so that the control center outputs the monitoring data counted by the log center.
The control center can output the monitoring data counted by the log center and send instructions to the server.
In the process of uploading the streaming media file, if the frame loss times are greater than a first preset value, a ground current breaking instruction sent by a control center is received; stopping receiving the streaming media file uploaded by the client; and sending the cutoff reason to the client. The first preset value is the maximum number of frame dropping allowed, and if the number of frame dropping exceeds the preset value, information of the streaming media file is lost, and smooth playing of the streaming media file cannot be guaranteed. In this embodiment, the size of the first preset value is not limited. If the streaming media file cannot be played smoothly, and the provider of the streaming media file continues to upload, the meaning of uploading the streaming media file is lost, and the waste of network resources is caused. Therefore, the control center sends a cut-off instruction to the streaming media server, and the streaming media server stops receiving the streaming media file uploaded by the client of the streaming media file provider and sends the cut-off reason to the client of the streaming media file provider.
In the process of uploading the fluid file, if the interval duration of receiving the key frame is greater than a second preset value, receiving a flow cutoff instruction sent by a control center; stopping receiving the streaming media file uploaded by the client; and sending the cutoff reason to the client. The key frames contain key information in the streaming media file, if the key frames are missing, the playing quality is directly reduced, and if no key frame exists within a time interval of a second preset value, the playing defect of the streaming media file may be caused. The playback defect includes a deletion of a playback frame of a playback file in a partial time period, a deletion of a partial audio, and the like. The second preset value is a fixed duration, and may also be dynamically adjusted, in this embodiment, the size of the second preset value is not limited, and the setting method of the second preset value is not limited.
And the control center is used for displaying the monitoring data and controlling the streaming media server to realize the monitoring of the transmission of the streaming media file.
Further, as a refinement of the method shown in fig. 1, another method for monitoring transmission of a streaming media file is further provided in the embodiments of the present invention, as shown in fig. 3, where the method includes:
301. monitoring data generated in the process of distributing the streaming media file by the real-time message transfer protocol RTMP streaming media server is collected.
Streaming media, which is "while" streaming media files are uploaded by a streaming media file provider, viewers can view the synchronized streaming media files. The streaming media server distributes the streaming media file, and the viewer can watch the synchronized streaming media file. If the streaming media file is distributed through the RTMP streaming media server, monitoring data of the RTMP streaming media server of a real-time message transmission protocol needs to be collected, wherein the monitoring data of the RTMP streaming media server comprises a client IP, a server IP, a stream ID and a frame loss identification bit. The client IP, the server IP, and the stream ID are the same as those described in step 201, and are not described again here.
And a frame loss identification bit for marking whether to lose frames in the distribution process of the streaming media file. If the data volume in the buffer register of the RTMP streaming media server is larger than a preset threshold value, discarding the data frame in the buffer register according to a preset discarding strategy; and recording a frame loss identifier at a frame loss identifier bit, wherein the frame loss identifier indicates that the RTMP streaming media server discards data frames in the process of distributing the streaming media file. Such frame loss is different from the frame loss in step 201, and the frame loss in this step is an active frame loss. The server actively discards the data frames under certain defined conditions.
In the process of transmitting a streaming media file, multiple servers are generally required to transmit the streaming media file from a provider of the streaming media file to a viewer of the streaming media file, and at least one server is required to transmit the streaming media file. Therefore, the active frame dropping mode exists between the server and the client and also between the server and the client.
In the process of distributing the streaming media file, the data frame is firstly stored in a buffer register of the RTMP streaming media server and then is sent to a receiver of the data frame of the next streaming media file, and if the network transmission speed of the next receiver is lower, the data volume in the buffer register is continuously increased. And if the data volume in the buffer register is larger than a preset threshold value, discarding the data frame in the buffer register according to a preset discarding strategy. The preset threshold is preset, and in this embodiment, the size of the preset threshold is not limited. For the discard policy, all data frames in the buffer register may be discarded, or part of data may be discarded.
After the data frame is discarded, the frame loss identification is recorded in the frame loss identification bit, which indicates that the data frame is discarded.
And collecting monitoring data of the RTMP streaming media server, and recording the monitoring data in a log form so as to further process the monitoring data.
302. And sending the monitoring data to a log center so that the control center outputs the monitoring data counted by the log center.
And the control center is used for displaying the monitoring data to realize the monitoring of the transmission of the streaming media file.

The client IP, the server IP, and the stream ID are the same as those described in step 201, and are not described again here. Bandwidth refers to the "highest data rate" that can be passed from one point in the network to another in a unit of time, i.e., how many bits per second. The bandwidth is used to identify the data transmission capability of the signal transmission, to identify the number of links passing through per unit time, and to identify the display capability of the display.
In the distribution process of the HLS streaming media file, the streaming media file is divided into a plurality of streaming media sub-blocks. The streaming media file is played from the streaming media file by taking a fixed playing time length as a segmentation standard, the fixed playing time length is divided into a streaming media block, and the streaming media file is sequentially divided into a plurality of streaming media sub-blocks according to the playing time sequence of the streaming media file. In this embodiment, the fixed playing time of the slicing criterion is not limited.
