The user can perform a stroking operation, which can be a left stroking or an upward stroking, and can also be a right stroking or a downward stroking, so that a video switching instruction can be generated, and the video switching instruction can correspond to different switching directions according to different stroking operations. If the current link (i.e. the link corresponding to the currently played video) is the first link of the play queue and the switching direction points to the inside of the play queue, the link in the switching direction of the current link in the play queue is skipped to, the video is played based on the link, i.e. the second link in the play queue, if the switching direction points to the outside of the play queue, the last link in the play queue can be skipped to, and the video is played based on the link.
In the process of implementing the present application, the inventor finds that the prior art has at least the following problems:
in the above technology, when a user browses a video corresponding to a first link in a play queue, an up-flipping instruction is generated by right-swiping or down-swiping, and then the terminal can display a video corresponding to a last link in the play queue, and when the video is displayed, the terminal can acquire a plurality of new links from the server to be added at the last part of the play queue, at this time, a next link of the link corresponding to the video being played in the play queue is not a first link in the play queue but a newly added link, at this time, if the user suddenly wants to switch back to a video seen before (i.e. a video corresponding to a first link), the user generally considers to perform an operation opposite to the previous operation, i.e. left-swiping or up-swiping, however, the operation can only be switched to a video corresponding to the newly added link, and the user needs to swipe up and down for finding the video seen before, thus, the efficiency of browsing is affected.

Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
The embodiment of the application provides a method for switching media data, which can be realized by a terminal. The terminal can be a mobile phone, a desktop computer, a tablet computer, a notebook computer, an intelligent wearable device and the like, and the terminal can be provided with a screen and other components. The terminal may have a function of displaying media data, a function of transmitting media data, and the terminal may be installed with an application program, such as a live application program, a short video application program. It should be noted that, in the present embodiment, an application is taken as a live application for example, and details are not described herein. The media data may be pictures, audio, video, etc.
When the user uses the live broadcast application program, the user can browse any type of live broadcast, and when the user browses the live broadcast, as shown in fig. 1, the user can generate a corresponding media data switching instruction by performing up-and-down-stroke or left-and-right-stroke on a screen, so that the screen displays the next live broadcast or the previous live broadcast of the current live broadcast, and the purpose of switching the browsed live broadcast by the user can be achieved.
Fig. 2 is a flowchart of a method for switching media data according to an embodiment of the present application. Referring to fig. 2, the process includes:
In implementation, a play queue is established, and a first preset number of links are obtained from the links of the media data received from the server and added to the play queue.
The first preset number of links comprises a first link, and the first link is the link with the first receiving time in the first preset number of links;
the specific processing of the above steps may be as follows:
first, a play queue is established.
When a media data acquisition instruction is received, an empty play queue is established.
Next, among the links of the media data received from the server, a first preset number of links is acquired.
After an empty play queue is established, the terminal may obtain a receive queue in which links of the media data from the server are stored, and may further obtain a first preset number of links from the receive queue.
And thirdly, adding the data into the play queue according to the sequence of the receiving time.
The links in the receiving queue may be arranged according to the sequence of the receiving time, and then the first preset number of links obtained in the above steps may be the previous first preset number of links in the receiving queue, and then the first preset number of links may be added to the play queue according to the sequence of the receiving time, and meanwhile, the terminal may label the links added to the play queue in the receiving queue, where the label may be an added identifier added to the links.
Optionally, after the processing is completed, in order to ensure that the user can browse smoothly, the terminal may preload media data, and may perform the following processing:
first, based on other links in the play queue except the first link, the corresponding media data is preloaded.
For example, there are five links in the play queue, and the terminal may preload media data corresponding to the remaining four links in the play queue when playing the media data corresponding to the first link.
Secondly, determining a second preset number of links with the first receiving time in the links which are received from the server and are not added to the play queue, and preloading corresponding media data based on the second preset number of links.
The terminal may also preload the links in the receiving queue, that is, determine the first preset number of links in the receiving queue, and then load the media data corresponding to the first preset number of links.
Optionally, the preloading may be performed only in the receiving queue, that is, the media data corresponding to the preset number of links are preloaded in the receiving queue, so that the media data corresponding to the links added to the play queue are all preloaded.
It should be noted that the receiving queue may include links arranged in the sequence of receiving time, and the number of links corresponding to the media data to be preloaded in the entire scheme may be unchanged, that is, if the media data to be preloaded is played, the media data corresponding to another link is preloaded.
Optionally, before the play queue is established, the terminal may also establish a receive queue, and the processing may be as follows:
when a user opens a live application program, a terminal can send a login notification to a server, and then the server can send links corresponding to each live media data to the terminal, the terminal can apply for a memory to establish an empty receiving queue, the terminal can receive the links of the media data from the server, and then the terminal can sequentially store each link into the receiving queue according to the sequence of the receiving time of each link, the terminal can also receive a packaged link packet, and store each link in the link packet into the receiving queue according to the packaging sequence of the link packet, and the terminal can also store each received link into the receiving queue according to a random sequence.
It should be noted that, in the present solution, a receiving queue that stores the receiving time sequence of each link is taken as an example for description, and details are not described herein.
In implementation, after the first preset number of links are added to the play queue, the terminal may obtain and access the first link in the play queue, further obtain media data corresponding to the first link, and play the media data, that is, the user may see live broadcasts corresponding to the first link on a screen of the terminal.
Wherein, the current link is a link corresponding to the currently played media data.
In implementation, a user may perform a top stroke, a left stroke, or a bottom stroke, and a right stroke when browsing the live broadcast, and then the live broadcast application may generate a corresponding media data switching instruction, and obtain a position relationship between the current link and the play queue, where the position relationship between the current link and the play queue may be that the current link is at a head end of the play queue, the current link is at a tail end of the play queue, the current link is not at the head end of the play queue, and the current link is not at the tail end of the play queue.
And step 204, determining a combination mode according to the switching direction and position relation of the switching instruction.
In implementation, after the processing of step 203 is completed, the live application may determine a combination mode according to the switching direction and the position relationship of the switching instruction, where the combination mode may be that the switching direction of the switching instruction is forward and is currently linked at the head end of the play queue, the switching direction of the switching instruction is backward and is currently linked at the tail end of the play queue, the switching direction of the switching instruction is forward and is currently linked at the head end of the play queue, the switching direction of the switching instruction is backward and is currently linked at the tail end of the play queue.
In practice, the method can be specifically processed by the following steps:
firstly, judging whether a link is corresponding to a switching instruction according to a combination mode, wherein the specific processing can be as follows:
and if the switching direction of the switching instruction is determined to be forward and the current link is at the head end of the play queue according to the combined mode, or the switching direction of the switching instruction is determined to be backward and the current link is at the tail end of the play queue according to the combined mode, determining that the switching instruction corresponds to the link.
For example, as shown in fig. 3, the current terminal plays the media data corresponding to B, and the user performs a downward stroke or a right stroke on the screen.
For another example, as shown in fig. 5, the current terminal plays the media data corresponding to a, and the user makes a top stroke or a left stroke on the screen.
And if the switching direction of the switching instruction is determined to be forward and the current link is not at the head end in the play queue according to the combination mode, or the switching direction of the switching instruction is determined to be backward and the current link is not at the tail end in the play queue according to the combination mode, determining that the switching instruction does not correspond to the link.
For example, as shown in fig. 4, the current terminal plays the media data corresponding to a, the user makes a down stroke or a right stroke on the screen, and the terminal detects that the current link has no previous link in the play queue.
For another example, as shown in fig. 6, the current terminal plays the media data corresponding to C, the user makes a top stroke or a left stroke on the screen, and the terminal detects that the current link has no next link in the play queue.
Next, the following processing may be performed according to the result of the determination:
and if so, playing the corresponding media data based on the link corresponding to the switching instruction.
For example, as shown in fig. 3, if the switching instruction of the combination mode corresponds to a link, the terminal may obtain a in the play queue, then access a, obtain media data corresponding to a, and then play the media data.
For another example, as shown in fig. 5, if the switching instruction of the combination mode corresponds to a link, the terminal may obtain B in the play queue, then access B, obtain media data corresponding to B, and then play the media data.
If not, acquiring a second link from the link which is received from the server and not added to the play queue, adding the second link at the adjacent position of the current link in the play queue in the switching direction, and playing the corresponding media data based on the second link.
For example, as shown in fig. 4, if the switch command of the combination mode is that no link exists, D in the receiving queue is obtained and added to the front of playlist a, and then the added identifier is added to D in the receiving queue. After the addition is completed, the terminal can obtain the second link in the play queue, then access the second link, obtain the media data corresponding to the second link, and further play the media data.
For another example, as shown in fig. 6, if the switch command of the combination mode is that there is no link corresponding to the switch command, D in the receiving queue is obtained and added to the back of the playlist C, and then the added identifier is added to D in the receiving list. After the addition is completed, the terminal can obtain the second link in the play queue, then access the second link, obtain the media data corresponding to the second link, and further play the media data.
And step 206, when the preset trigger condition is reached, sending a link request to the server, and receiving the link sent by the server.
In implementation, while the above steps are performed, the terminal may receive the link sent by the server, and the specific processing may be performed in the following manners:
first, when there is no link locally received from the server and not added to the play queue, a link request is sent to the server.
When detecting that all links in the receive queue are added to the play queue, i.e. when detecting that all links in the receive queue have an added identity, the terminal may send a link request to the server.
Second, when the number of links received from the server and not added to the play queue is less than a first number threshold, a link request is sent to the server.
When detecting that the number of links in the receiving queue which are not added to the playing queue is less than a first number threshold value, namely when detecting that the number of links in the receiving queue which do not have an added identifier is less than the first number threshold value, sending a link request to the server.
For example, the first number threshold may be set to a smaller number, such as 1, and when it is detected that the number of links in the receive queue that do not have an added identity is less than 1, a link request is sent to the server.
Thirdly, when the preset period is reached, if the number of the links which are received from the server and are not added to the play queue is less than the second number threshold, a link request is sent to the server.
The terminal may periodically detect whether the number of links in the receiving queue that are not added to the play queue is less than a second number threshold, i.e. when detecting that the number of links in the receiving queue that do not have an added identity is less than the second number threshold, send a link request to the server.
For example, the second number threshold may be set to a number larger than the first number threshold, so as to form a virtual candidate pool from which the terminal can obtain links, for example, 15, and when detecting that the number of links without the added identifier in the receiving queue is less than 15, the server sends a link request.
And after the link request is sent to the server, receiving the link sent by the server.
After sending the link request to the server, the terminal may receive a preset number of links sent by the server, where the preset number may be set by a technician, so that the number of links sent by the server is preset every time, and the terminal may sequentially store the links in the receive queue according to the receive time.
Optionally, the link request may further include the number of links, and after the link request is sent to the server, the link sent by the server is received.
The link request may further include the number of links, and after the link request is sent to the server, the terminal may receive the number of links sent by the server.
According to the method and the device, the playing queue is established, and the first link in the links of the media data received from the server is added to the playing queue, so that the media data corresponding to the first link is played. And when a media data switching instruction is received, acquiring the position relation between the current link and the play queue. And determining the combination mode according to the switching direction and the position relation of the switching instruction. And then judging whether the switching instruction corresponds to a link according to the combination mode, if so, playing corresponding media data based on the link corresponding to the switching instruction, otherwise, acquiring a second link in the link which is received from the server and is not added to the playing queue, adding the second link at the adjacent position of the current link in the playing queue in the switching direction, and playing the corresponding media data based on the second link. Therefore, the sequence of each media data can be arranged according to the sequence of the media data displayed when the user moves in the past, so that the situation that the media data are not easy to find can be avoided, and the efficiency of browsing the media data can be improved.
All the above optional technical solutions may be combined arbitrarily to form the optional embodiments of the present disclosure, and are not described herein again.
