Based on the above description, fig. 2 exemplarily shows a flow of a method for acquiring audio and video data according to an embodiment of the present invention, where the flow may be performed by an apparatus for acquiring audio and video data. The process will be described below by way of interaction between the client, the index server and the edge device, and as shown in fig. 2, the process specifically includes:
step 201, the client receives an audio and video playing instruction.
The audio and video playing instruction comprises the code rate of audio and video data to be played; the code rate refers to the data flow used by the audio and video files in unit time, and the popular understanding is the sampling rate, which is the most important part in the quality control of pictures and sound in audio and video coding.
After receiving the audio and video playing instruction, the client determines the audio and video data to be played and the code rate of the audio and video data to be played according to the audio and video playing instruction. And the client requests a small amount of audio and video data for starting playing from the CDN server according to the audio and video data to be played and the code rate of the audio and video data to be played.
In step 202, the client sends a first request to the index server.
The client sends a first request to the index server according to the audio and video data to be played and the code rate of the audio and video data to be played, and the first request is used for acquiring the edge device list from the index server.
Here, the first request is sent by the client after receiving an audio and video playing instruction, and the first request comprises the code rate of audio and video data to be played; the edge device list can be understood as a list formed by edge devices, which is determined by the index server according to the code rate of the audio/video data to be played, wherein the audio/video data corresponding to the code rate of the audio/video data to be played is stored on the edge devices, that is, the edge devices are audio/video data edge devices or other devices which are determined by the index server in the resource list and stored with the code rate corresponding to the audio/video data to be played, and the edge device list is a set of all the edge devices.
And 203, the index server determines an edge device list from the resource list according to the code rate of the audio and video data to be played.
Specifically, after receiving a first request sent by a client, an index server determines an edge device list from a resource list according to the code rate of audio/video data to be played in the first request, where the edge device list includes a plurality of edge devices, and the edge devices store the audio/video data corresponding to the code rate of the audio/video data to be played.
As an implementation manner, the index server generates a first task list according to the received first requests of the preset number of clients, where the first task list may be understood as a task list generated according to the most popular request of the audio and video data in the current environment. After receiving a request for acquiring the first task list sent by the edge device, the index server feeds the first task list back to the edge device, so that the edge device downloads audio and video data corresponding to the first task list according to the first task list. Further, the index server receives the index list of the audio and video data sent by the edge device, and updates the resource list according to the index list of the audio and video data sent by the edge device.
Here, the index list of the audio/video data is generated after the edge device transcodes the audio/video data corresponding to the first task list, that is, the index list of the audio/video data is obtained after processing the audio/video data downloaded from the CDN server, and the index list of the audio/video data includes the ID of the edge device and the code rate of the audio/video data; the resource list is stored in the index server, the resource list is the index list of the audio and video data sent to the index server by each edge device, and the index server updates the resource list when receiving the index list of the audio and video data sent by the edge device.
In another aspect, the edge device may periodically send a request for obtaining the first task list to the index server, so as to periodically obtain the first task list from the index server, and download, from the CDN server, the audio and video data corresponding to the first task list according to the obtained first task list, so that the edge device downloads the hottest audio and video data in the current environment. Further, the edge device transcodes the audio and video data corresponding to the first task list by using the computing power of the edge device, that is, the edge device transcodes the audio and video data according to the downloaded audio and video data by using the computing power of the edge device. Optionally, the edge device may transcode the audio/video data corresponding to the first task list by using a Central Processing Unit (CPU) idle time. Meanwhile, the edge device can also generate an index list of the downloaded audio and video data and the transcoded audio and video data according to the ID of the edge device, namely the edge device generates the index list of the audio and video data according to the code rate of the transcoded audio and video data and the ID of the edge device, and finally sends the generated index list of the audio and video data to an index server so that the index server updates the resource list.
For example, the edge device is a router 1, the ID is "router 1", the router 1 sends a request for obtaining a first task list to an index server, the index server generates a first task list according to a plurality of first requests, and feeds back the first task list to the router 1 according to the request of the router 1, where the first task list represents a part of the hottest audio/video data in the current environment, as shown in table 1. After obtaining the first task list, the router 1 downloads the audio and video data corresponding to the first task list from the CDN server, that is, downloads a.mp4, b.mp4, and c.mp4 from the CDN server. After downloading, the router 1 transcodes the downloaded audio and video data by using the idle time of its own processor, specifically, transcode "a.mp 4" to "a. _550.mp 4", transcode "b.mp 4" to "B. _900.mp 4", transcode "c.mp 4" to "C. _900.mp 4" and "C. _550.mp 4", and generate an index list according to the code rate of the transcoded audio and video data and the ID of its own device, which may be as shown in table 2, and send the index list to an index server, and the index server updates a resource list.

Router 1 C.mp4 C._900.mp4、C._550.mp4
In step 204, the index server sends the edge device list to the client.
And the index server sends the determined edge device list to the client so that the client can acquire the audio and video data corresponding to the code rate of the audio and video data to be played from the edge device according to the edge device list.
In step 205, the client sends an audio and video data download request to the edge device.
And after receiving the edge device list sent by the index server, the client acquires audio and video data corresponding to the code rate of the audio and video data to be played from the edge device according to the edge device list. In specific implementation, the client may send an audio and video data download request to the edge device in the edge device list, where the audio and video data download request includes a code rate of audio and video data to be played, and when the edge device feeds back the audio and video data corresponding to the code rate of the audio and video data to be played to the client, the client receives the audio and video data corresponding to the code rate of the audio and video data to be played.
In addition, when the client does not acquire the edge device list from the index server, that is, the client cannot acquire the audio and video data corresponding to the code rate of the audio and video data to be played from the edge device, the client needs to acquire the audio and video data corresponding to the code rate of the audio and video data to be played from the CDN server. That is, the client firstly indexes the server to obtain the edge device list, and if the edge device list is obtained, the client obtains audio and video resources from the edge device according to the edge device list; and if the audio/video resources cannot be obtained, the audio/video resources can be obtained only from the CDN server.
And step 206, the edge device determines audio and video data corresponding to the code rate of the audio and video data to be played according to the code rate of the audio and video data to be played and the index list of the audio and video data.
The method comprises the steps that an edge device receives an audio and video data downloading request sent by a client, wherein the audio and video data downloading request comprises the code rate of audio and video data to be played, and the edge device determines the audio and video data corresponding to the downloading request, namely the audio and video data corresponding to the code rate of the audio and video data to be played according to the code rate of the audio and video data to be played and an index list of the audio and video data.
And step 207, the edge device sends the audio and video data corresponding to the code rate of the audio and video data to be played to the client.
In the above embodiment, the edge device list may include at least one edge device, and when the client acquires the audio and video data corresponding to the code rate of the audio and video data to be played, it may happen that one or some edge devices are abnormal, for example, the edge device goes down, is powered off, or the like, at this time, the client cannot continuously acquire the audio and video data corresponding to the code rate of the audio and video data to be played from the abnormal edge device, and the client needs to acquire the edge device list from the index server again according to the code rate of the audio and video data to be played until all the audio and video data corresponding to the code rate of the audio and video data to be played are acquired.
For example, when the client acquires the required audio and video data from the three devices a, b, and c, the client may acquire the edge device list from the index server again, where the acquired edge device list is a, c, and d, and the client acquires all the required audio and video data from the three devices a, b, and c, and the client may not acquire all the required audio and video data due to the power failure of the device b.
