The playing client 101b for playing video data is configured to log in a playing account, specifically enter a corresponding APP, create a corresponding player when the APP display interface determines to display the video data, establish a connection with a server by the player, obtain video source data from the server, decode the video source data, and display the decoded video data for viewing by a user.
The server 102 receives an uploading operation instruction sent by an uploading account and stores video source data uploaded by the uploading account into a database; and receiving a playing instruction sent by the playing account, calling a related process to transmit video source data uploaded by the uploading client to the playing client, so that the playing client calls the player to decode, and displaying the decoded video data.
And the database 103 is used for storing the video source data uploaded by the uploading client.
In the embodiment of the disclosure, the live broadcast client and the on-demand client are electronic devices used by users, and the electronic devices can be personal computers, mobile phones, tablet computers, notebooks, electronic book readers and other computer devices with certain computing capacity and running instant messaging software and websites or social software and websites. The servers can be independent physical servers through a wireless network and servers, can be server clusters or distributed systems formed by a plurality of physical servers, and can also be cloud servers for providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (content delivery network), basic cloud computing services such as big data and artificial intelligent platforms and the like.
Fig. 2 is a flowchart illustrating a video data playing method according to an exemplary embodiment, and as shown in fig. 2, the method specifically includes the following steps:
in step 201, in response to a request for displaying video data, invoking a corresponding processing unit to query a player corresponding to the video data from a shared area, wherein data in the shared area is for access by different processing units;
the video data includes recorded video data and real-time video data (i.e., live video data).
The request for displaying the video data carries the identifier of the corresponding video data, and the player identifier corresponding to the video data can be queried from the shared area according to the identifier of the video data.
As an optional implementation manner, the querying, by the processing unit corresponding to the call, a player corresponding to the video data from the shared area includes:
invoking a corresponding processing unit to inquire a player identifier corresponding to the video data from the shared area;
and inquiring the player corresponding to the video data according to the player identification when the player identification corresponding to the video data is found.
According to the player identification corresponding to the video data, the player corresponding to the player identification is queried, and the query speed of the player is improved.
The above-mentioned response to the request for displaying video data, before invoking the corresponding processing unit to query the player corresponding to the video data from the shared area, further includes:
the shared area is created in a single instance in advance, and the attribute of the shared area is set to be shared so as to be accessible by different processing units, and the shared area is created in the system memory.
The player, as well as the player identification and the object currently referring to the player, are stored in the above-mentioned shared area in a dictionary manner, i.e. the player identification is taken as a key, and the pointing object of the key (the referring object of the player) is recorded.
The player identifier may be an identifier corresponding to video data decoded by the player.
In step 202, when a player corresponding to the video data is found, acquiring the video data decoded by the player through a processing unit, and displaying the decoded video data;
when the player corresponding to the video data is found, the processing unit accesses the corresponding player according to the player identification, acquires the decoded video data from the player, and then renders and displays the video data on the corresponding interface.
After receiving the video data display request, the method firstly inquires the player identification corresponding to the video data from the shared area, and when inquiring, the method indicates that the corresponding player is established for the current video data, and the player does not need to be re-established to pull streams from the server, so that the video data decoded by the player is directly obtained through the player identification.
The method provided by the disclosure can avoid decoding a plurality of players which are created for the same video data, and compared with the method for creating a new player and carrying out streaming in the prior art, the method provided by the disclosure can save the time for creating the player and carrying out video streaming, greatly reduce the waiting time of a user when carrying out interface switching, and avoid the splitting of the user watching experience and the loss of live broadcast content.
In the step 201, when the player corresponding to the video data is not found, a player uniquely corresponding to the video data is newly created, and connection is established between the newly created player and the server, so as to obtain and decode the video data;
storing the newly created player in the shared area, acquiring the decoded video data of the newly created player through the processing unit, and displaying the decoded video data.
And when the player corresponding to the video data is not found, the player is newly created and stored in the shared area, so that the player can be conveniently and directly acquired from the shared area when the next inquiry is performed, and the waiting time of a user when the interface is switched is reduced.
It should be noted that, the player and the video data have a unique correspondence, that is, represent video data of a player that corresponds to a source video.
When the player corresponding to the video data is not found, a new player is created, video source data is acquired from the server through the new player, and the acquired video source data is decoded to obtain the corresponding decoded video data.
After the new player is created, the identifier of the player is stored in the shared area, so that the video data decoded by the player is acquired through the identifier of the player when the request for displaying the same video data is received next time.
And the processing unit acquires the decoded video data from the player, and then renders and displays the video data on a corresponding interface for a user to watch.
The video data decoded by the player is obtained through the player identification in the sharing area through the data connection between the player and the processing unit, and the player and the processing unit are in one-to-one corresponding data connection.
As an optional implementation manner, the acquiring, by the processing unit, the video data decoded by the player/newly created player includes:
and establishing a data connection between the processing unit and the player/newly created player, and acquiring video data decoded by the player/newly created player based on the data connection through the processing unit.
The data connection is realized by pointing the player identification to the reference object in the shared area, namely, the data connection between the processing unit and the player can be established by pointing the player reference object to the processing unit, and the server can access the connected player according to the data connection and acquire the decoded video data from the player.
It should be noted that, although the processing unit that establishes the data connection with the player may be changed, one player may only establish the data connection with one processing unit, and may not establish the data connection with a plurality of processing units at the same time.
After the data connection between the processing unit and the player corresponding to the player identification is established, the created player can be directly accessed through the data connection and the decoded video data can be obtained from the player, and the player does not need to be newly created and video streaming is carried out, so that the switching time is greatly reduced.
As an alternative embodiment, the data connection of the processing unit to the corresponding player is deleted upon receipt of an end display instruction.
The display is finished through deleting the data connection between the processing object and the corresponding player, but the corresponding player is not deleted, so that repeated establishment and deletion of the player are avoided.
In practice, the processing unit is terminated to acquire the decoded video data from the player by deleting the data connection between the processing unit and the corresponding player.
As an optional implementation manner, any player in the shared area is determined, and when no data connection is established with a different processing unit within a preset time, the player is deleted from the shared area to stop acquiring corresponding video data from the server.
In implementation, when the player identification of the shared area is monitored to be empty, deleting the player corresponding to the player identification and the identification stored in the shared area.
The player which is not connected with the processing unit in the preset time is deleted, and the player is deleted from the shared area, so that the resource waste caused by the occupation of the storage space by the player is avoided.
As an alternative embodiment, in response to a request for displaying video data, invoking a corresponding processing unit to query a player corresponding to the video data from a shared area, including:
