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 application.
The embodiment of the application provides a method for playing a video, which can be applied to an agent component, wherein the agent component is a software module in electronic equipment, and a player is a software module in the electronic equipment for playing the video.
A method for playing a video provided in an embodiment of the present application will be described in detail below with reference to specific embodiments, as shown in fig. 1, the specific steps are as follows:
The virtual m3u8 file is a video file, the virtual m3u8 file can store a plurality of video mapping addresses, the video mapping addresses can map download addresses of TS files in a remote server, and the TS files can be a plurality of files containing video data at a certain video bitrate. In practical application, one video may have TS files with multiple video bit rates, and each video bit rate has a TS file with a corresponding bit rate. The video code rate is the number of data bits transmitted in unit time during data transmission, the common unit is kbps (kilobits per second), the larger the number of data bits transmitted in unit time is, the higher the precision is, and the closer the processed video file is to the original file.
In the embodiment of the application, a client for playing a video may be installed in the electronic device, and the client may include a player and a proxy component. The user can select the video to be played at the client, and the client can receive the playing instruction corresponding to the video and transmit the playing instruction to the player, so that the player performs video playing processing after receiving the playing instruction. At this time, the proxy component may detect that the player plays a video, send a request for obtaining a file with a preset video bitrate to the remote server, and obtain a video mapping address of a TS file with a certain video bitrate from the remote server, and at the same time, the proxy component may create a file, and store a plurality of video mapping addresses obtained by the remote server into the file, so as to form a virtual m3u8 file.
Optionally, when it is detected that the player plays a video, a specific processing procedure of the step of generating the virtual m3u8 file may be: when a video playing request transmitted by a player is received, a virtual m3u8 file is generated.
In the embodiment of the application, when the player receives a video playing instruction transmitted by the client, a video playing request is transmitted to the proxy component. The player transmits a request to play the video with the purpose of obtaining a virtual m3u8 file. When the agent component receives the request transmitted by the player, a virtual m3u8 file may be generated, the virtual m3u8 file contains a plurality of preset video mapping addresses, and each video mapping address may be a download address of the TS file in a remote server. Therefore, the agent component may download a TS file, which is a file containing video data, through the video mapping address in the virtual m3u8 file, and a plurality of TS files downloaded through the video mapping address in the virtual m3u8 file may constitute a complete piece of video. And when the player acquires the virtual m3u8 file, the video can be played.
And 102, downloading a first Transport Stream (TS) file corresponding to the first video mapping address according to the first video mapping address in the virtual m3u8 file.
The first video mapping address is a video mapping address of a first TS file in a remote server.
In this embodiment of the application, after the player acquires the virtual m3u8 file, the proxy component may determine, according to the sequence of playing the TS files, a first video mapping address corresponding to a first TS file in the virtual m3u8 file, and download, to the local, the first TS file in the remote server corresponding to the first video mapping address.
And 103, when the first TS file is played completely, if the first video code rate is determined to be switched to the second video code rate, determining a second video mapping address corresponding to the second video code rate.
In the embodiment of the application, when the first TS file is played, the agent component may determine whether the video played by the player should switch the code rate according to the current network environment. The purpose of the judgment is to match TS files with suitable code rates for the player according to the network environment, so that the video with the highest code rate is played on the premise that the player can play the video smoothly. If the agent component judges that the first video code rate is switched to the second video code rate, the agent component can switch the first video code rate to the second video code rate in a mode of switching the video mapping address.
Optionally, the process of determining whether to switch the code rate may specifically include the following steps:
step one, when the first TS file is played, determining a first average downloading speed of the electronic equipment for downloading the first TS file.
In this embodiment of the application, when the first TS file is completely played, the agent component may determine the size of the data size of the first TS file and the time for downloading the first TS file, and calculate a ratio of the data size to the time to obtain an average downloading speed of the electronic device for downloading the first TS file. The average download speed reflects the current network environment, and the agent component can judge whether to switch the code rate according to the average download speed.
And step two, determining a second video code rate corresponding to the first average downloading speed according to the corresponding relation between the preset average downloading speed and the video code rate.
In the embodiment of the present application, the corresponding relationship between the average downloading speed and the video bitrate is as follows: one download speed interval corresponds to one video bitrate. And the proxy component determines a downloading speed interval where the current average downloading speed is located, and further determines a second video code rate corresponding to the downloading speed interval according to the corresponding relation between the preset average downloading speed and the video code rate.
An example of a corresponding relationship between an average download speed and a video bitrate is provided in an embodiment of the present application, and specific examples may include: in this example, there are two code rates: 350Kbps (fluent bitrate) and 800Kbps (high definition bitrate). When the average downloading speed determined by the proxy component is greater than the smooth code rate and less than the high-definition code rate, the proxy component can switch the current video code rate to the smooth code rate, and when the average downloading speed determined by the proxy component is greater than the high-definition code rate, the proxy component can switch the current video code rate to the high-definition code rate. If the average download speed determined by the proxy component is 560K/S (560Kbps per second), the current situation is that the average download speed determined by the proxy component is greater than the smooth bitrate and less than the high definition bitrate, and the proxy component can switch the current video bitrate to the smooth bitrate.
And step three, if the first video code rate is different from the second video code rate, determining a second video mapping address corresponding to the second video code rate.
In the embodiment of the application, if the first video code rate is different from the second video code rate, the agent component determines to switch the first video code rate to the second video code rate. After determining that the first video code rate is switched to the second video code rate, the proxy component may send a request for obtaining a second TS file to the remote server, and after receiving the request, the remote server sends a second video mapping address corresponding to the second video code rate to the proxy component.
Optionally, the process of obtaining the second video mapping address may specifically include the following steps:
step one, if the first video code rate is determined to be switched to the second video code rate, sending an acquisition request of a video mapping address to a remote server.
The obtaining request carries a second video code rate and a preset file identifier of a second TS file, so that the remote server determines a second video mapping address according to the second video code rate and the file identifier.
In the embodiment of the application, when the proxy component determines to switch the first video bitrate to the second video bitrate, a request is made to a remote server for obtaining a second TS file corresponding to the second video bitrate, and the obtaining request carries the second video bitrate and a preset file identifier of the second TS file. When the remote server receives the request, the remote server retrieves the second TS file according to the identifier provided by the proxy component and determines a second video mapping address of the second TS file.
And step two, receiving a second video mapping address sent by the remote server.
In this embodiment of the application, after determining the second video mapping address of the second TS file, the remote server may send the second video mapping address of the second TS file to the proxy component, and after obtaining the second video mapping address of the second TS file, the proxy component may download the second TS file through the second video mapping address.
And 104, downloading a second TS file corresponding to the second video mapping address, and transmitting the second TS file to the virtual m3u8 file, so that the player reads the second TS file from the virtual m3u8 file and plays the second TS file.
In this embodiment of the application, after the agent component determines the second video mapping address, the second TS file may be downloaded through the second video mapping address, and after the agent component downloads the second TS file, the player may read the second TS file from the virtual m3u8 file and play the second TS file. The player plays the TS files sequentially while playing the video, so that after the first TS file is played, the player can obtain the most suitable second TS file from the virtual m3u8 file to achieve the purpose of smooth playing.
As shown in fig. 2, an embodiment of the present application provides a specific example of playing a video, and the specific steps may include:
as shown in table one, an example of a corresponding relationship between the average download speed and the video bitrate is provided for this example, where the corresponding relationship is a preset corresponding relationship, and the proxy component can match the average download speed with the appropriate bitrate according to the preset relationship.

And 204, judging a second video code rate corresponding to the first average downloading speed according to the preset corresponding relation. If the first average download speed is less than 800K/bps, step 205 is executed, if the first average download speed is greater than 800K/bps and less than 1.5M/bps, step 206 is executed, and if the first average download speed is greater than 1.5M, step 207 is executed.

And step 207, sending a request for acquiring the super clear rate mapping address to the remote server.
And step 208, receiving a second video mapping address sent by the remote server.
And step 209, downloading a second TS file corresponding to the second video mapping address, and storing the second TS file in the virtual m3u8 file, so that the player reads the second TS file from the virtual m3u8 file and plays the second TS file.
