The application provides a video playing method, which aims to solve the problem that video playing cannot be timely recovered in the prior art.
Optionally, in order to implement the method for playing a video provided by the present application, an embodiment of the present application provides a video playing system. As shown in fig. 1, a video playing system provided in an embodiment of the present application includes:
a playing gateway 101, a playing back end 102, a backup playing back end 103, and a playing operation background 104.
The playing gateway 101 is configured to obtain and cache a target backup address generated by the operation background 104, receive a request for obtaining a video playing string sent by the client, and then determine whether to cache the corresponding target backup address, so as to determine whether to feed back an original playing string of the video obtained by the playing back end to the client or to feed back a backup playing string of the video obtained by the backup playing back end 103 to the client.
The playing back end 102 provides a main interface for playing data for the client, and serves for video playing. The method is mainly used for providing playing data to the client through the playing gateway 101 when the video is played normally.
The backup playing back end 103 provides a backup interface for playing data for the client, and is mainly used for providing backup playing data, i.e. providing a backup playing string of the video, to the client through the playing gateway when the video cannot be played normally.
The playing operation background 104 is mainly used for dynamically setting a backup address corresponding to a corresponding video or a backup address corresponding to a client according to a playing failure condition when the playing fails.
Based on the video playing system provided above, another embodiment of the present application provides a video playing method, as shown in fig. 2, including the following steps:
s201, receiving a request for acquiring a play string of a target video, which is sent by a target client.
The play string of the target video refers to an address of a play file storing the target video. And the target video refers to a video requested by a user, and when the user requests the video through the client, the client sends a request for acquiring a play string of the target video to the play gateway.
Optionally, the request usually includes information of the target video, information of the client, and the like. Such as the identification of the target video and the identification of the client.
S202, judging whether a target backup address exists or not; the target backup address comprises a backup address corresponding to the target client and/or a backup address corresponding to the target video.
The backup address corresponding to the target client is an address which is set before the current request is received and when the target client cannot play the video and is used for storing the backup play string of any video.
When a problem occurs in the device and user logic processing, the playing server may cause that a particular client cannot normally acquire the playing string of the video from the playing back end and play the video, so that the video cannot be normally played. Therefore, in the embodiment of the present application, when a client that receives user feedback cannot normally play a video or detects that a certain client cannot normally play a video, a corresponding backup address is set for the client, so that when the client requests to play a video again, a request of the client is guided to the corresponding backup address to obtain a backup play string of the video, thereby recovering a function of the client that normally plays the video in time. For example, for an ID of: 2dc80, when the client cannot play video, the playing operation background sets corresponding backup address for the client as: "https:// bac. Bz. Mgtv.com/source", the interface defaults to VIP authority, and the playout gateway can obtain the ID and corresponding backup address of the client and then associate and cache them, such as: "2dc80- > https:// bac. Bz. Mgtv. Com/source".
And setting a backup address corresponding to the target video before receiving the current request and when the target video cannot be normally played. Because the video file has an error or cannot be played incorrectly, the target video normally acquired from the playing back end cannot be played, or the target video cannot be normally acquired from the playing back end. Therefore, in the embodiment of the application, when the target video cannot be played normally, the corresponding backup address is set, and when the client requests to play the target video, the backup play string of the target video is fed back to the client based on the backup address, so that the normal play of the target video is restored in time.
It should be noted that the target video that cannot be played normally is divided into two cases, one is a special case of the target video and a case that the target video cannot be played normally, and the other is a case that both the entire client and the video cannot be played normally, and the case also includes the case that the target video cannot be played. The first situation is usually caused by an error in the file of the target video normally acquired, and the second situation is usually caused by a failure in the playback service.
Alternatively, the backup address may be set only for the target video for the first case, thereby avoiding unnecessary work. Specifically, when the target video cannot be normally played in a monitored state or when the target video cannot be normally played after receiving feedback of a plurality of users, a fixed backup address is set for the target video in the playing operation background, so that the normal playing of the target video is timely recovered. And, the backup play string of the target video can be set as the backup address corresponding to the target video. For example, when monitoring or receiving feedback, the video "sister who breaks the wave by riding wind, stage 6" fails to be played, the ID of the video is 10000, and at this time, the corresponding backup address is set for the video as follows: "https:// www.mgtv.com/10000.m3u8", video ID and backup address can also be associated and stored by the playout gateway as: "10000- > https:// www.mgtv.com/10000.m3u8".
For the second case, when it is monitored that the whole client cannot play the video, a backup address can be set for a plurality of videos. The backup play string of each video in the plurality of videos can be found according to the backup address, so that the normal play of the plurality of videos can be restored in time. Alternatively, backup addresses may be set for all videos. However, in consideration of the workload and necessity, the backup address may be set only for a part of videos, for example, only for a hot video.
Optionally, after the backup address is set, the backup address may be cached in the playback gateway, so as to determine whether the target backup address exists in time. The specific caching mode comprises the following steps: and regularly polling and playing each target data in the operation background through the playing gateway. The target data comprise a backup address corresponding to the client, a backup address corresponding to the video, a client identifier and a video identifier.
And then associating the backup address corresponding to the client with the client identifier corresponding to the client, associating the backup address corresponding to the video with the video identifier corresponding to the video, and caching the associated target data into the play gateway.
It should be noted that, when it is determined that the target backup address exists, it is indicated that the target client can normally play the target video only by acquiring the backup play string of the target video, so step S203 is executed at this time. If it is determined that the target backup address does not exist, step S205 is executed.
S203, determining a backup play string of the target video based on the target backup address.
And the backup play string of the target video is the address of the backup play file of the target video.
Since the target backup address may correspond to a plurality of videos, a backup play string of the target video needs to be determined based on the target backup address.
It should be noted that, if a backup address corresponding to the target client and a backup address corresponding to the target video exist at the same time, the backup play string of the target video may be determined based on the backup address corresponding to the target client, or the backup play string of the target video may be determined based on the backup address corresponding to the target video, and both of the two manners may ensure that the target client plays the target video.
Optionally, since the target backup address includes a backup address corresponding to the target client and/or a backup address corresponding to the target video, an embodiment of steps S202 to S203, as shown in fig. 3, includes:
s301, judging whether a backup address corresponding to the target client exists.
That is to say, in the embodiment of the present application, it is preferentially determined whether a backup address corresponding to a target client exists. Of course, this is only one of the optional execution sequences, and both may be determined at the same time, or it is determined whether a backup address corresponding to the target video exists first.
If it is determined that the backup address corresponding to the target client does not exist, step S302 is performed. If it is determined that the backup address corresponding to the target client exists, step S303 is directly performed.
S302, judging whether a backup address corresponding to the target video exists.
If it is determined that the backup address corresponding to the target video exists, step S304 is executed. If it is determined that the backup address corresponding to the target video does not exist, it indicates that the target backup address does not exist, so step S205 is executed at this time.
S303, finding out the backup play string of the target video from the position indicated by the backup address corresponding to the target client.
S304, determining the backup address of the target video based on the backup address corresponding to the target video.
And S204, feeding back the backup play string of the target video to the target client for playing.
S205, obtaining an original play string of the target video, and feeding the original play string of the target video back to the target client for playing.
The original playing string of the target video is the address of the original playing file of the target video, and when the target backup address does not exist, the target client can normally play the target video, so the original playing string of the target video is normally acquired from the playing back end at the moment, and the original playing string of the target video is fed back to the target client for playing.
According to the video playing method provided by the embodiment of the application, when a client cannot play a video, a backup address corresponding to the client is set, and the backup address can be used for obtaining a backup playing string of any one video, so that when the playing string of the target video sent by the client is obtained, the backup playing string of the target video can be determined according to the existing backup address corresponding to the client and fed back to the client, the client can play the video by using the backup playing string, and the video playing function of the client is restored in time. And when the target video cannot be played normally, setting a backup address corresponding to the target video, determining a backup playing string of the target video according to the existing backup address corresponding to the target video, and feeding back the backup playing string to the client, so that the client can play the video by using the backup playing string of the target video and restore the normal playing of the target video in time. Therefore, the video playing method provided by the embodiment of the application can quickly recover the playing of the video no matter the client has a problem and the video cannot be normally played, and does not need to wait for the maintenance of technicians on the problems.
Optionally, another embodiment of the present application provides another video playing method, as shown in fig. 4, including the following steps:
s401, receiving a request for acquiring the play string of the target video sent by the target client.
S402, judging whether a backup address corresponding to the target client exists or not.
The backup address corresponding to the target client is an address which is set when the target client cannot play the video and is used for acquiring the backup play string of any one video. The specific setting process of the backup address corresponding to the target client may refer to the corresponding description in step S202, and is not described herein again.
It should be noted that, in the embodiment of the present application, it is preferentially determined whether a backup address corresponding to the target client exists, and when it is determined that the backup address corresponding to the target client does not exist, step S404 is executed. If it is determined that the backup address corresponding to the target client exists, step S403 is performed.
S403, searching the backup play string of the target video from the position indicated by the backup address corresponding to the target client.
Optionally, an implementation of step S403, as shown in fig. 5, includes the following steps:
s501, removing the parameters of the specified type in the request to obtain the backup video request.
And at least keeping the identification of the target video in the backup video request.
Because the back end can make many business logic judgments according to some attributes of the client, and finally a special play string may be returned, and there may be a situation that the play cannot be performed. It is necessary to remove the parameters related to the device in the request, such as the device name, user credentials, etc., and retain some necessary parameters such as the video ID, etc., so as to convert the request into a generic request, rather than a specific request for the target client, i.e., to exclude specificity.
S502, the request with the parameters removed is forwarded to a backup playing back end, so that a backup address corresponding to the target client is found out from the position indicated by the backup address corresponding to the target client through the backup playing back end.
S404, judging whether a first backup address exists or not.
When any client cannot play, the backup play string of the target video is configured as a first backup address and cached in the play gateway. It should be noted that the first backup address is a backup address set for the target video when the target video cannot be played normally. Since the backup address is set for only one video, the backup play string of the target video can be directly configured as the first backup address. For more specific setting process, reference may be made to corresponding description in step S202, and details are not described herein again.
When it is determined that the first backup address exists, step S405 is performed. If it is determined that the first backup address does not exist, step S406 is performed.
S405, determining the first backup address cached in the playing gateway as a backup playing string of the target video.
Since the backup play string of the target video is directly configured as the first backup address and cached in the playback gateway in the embodiment of the present application, the first backup address cached in the playback gateway can be directly determined as the backup play string of the target video and fed back to the target client, that is, the first backup address is directly fed back to the target client.
S406, judging whether a second backup address exists or not.
The second backup address is configured when any client cannot play the video, and is used for acquiring addresses of backup play strings of the plurality of videos. It should be noted that the first backup address is a backup address set for a plurality of videos when the entire client cannot play and identify the videos. For a specific setting process, reference may be made to corresponding descriptions in step S202, and details are not described herein again.
When it is determined that the second backup address exists, step S407 is performed. When it is determined that the second backup address does not exist, since the second backup address is determined last, it is indicated that the target backup address does not exist, so step S408 is performed at this time.
S407, the backup play string of the target video is found out from the storage space indicated by the second backup address.
S408, obtaining the original playing string of the target video, and feeding back the original playing string of the target video to the target client for playing.
And S409, feeding back the backup play string of the target video to the target client for playing.
