Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The method for playing the first screen can be applied to the application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.
Specifically, when the first screen is played, the terminal 102 requests live broadcast data, and the server 104 obtains the length of the buffer area of the player in the terminal 102, so that frame skipping transmission is performed according to pre-stored frame data, that is, the phenomenon that the first screen is blank in the terminal 102 can be effectively avoided, and the time delay of the first screen playing can be effectively reduced.
In an embodiment, as shown in fig. 2, a method for playing a first screen is provided, which is described by taking the method as an example for being applied to the server in fig. 1, and includes the following steps:
The terminal can be a terminal operating in environments such as Android, IOS, windows phone, and the like. The configuration information refers to the length of the buffer corresponding to the player, generally speaking, the unit of the length of the buffer is bytes, for example, the length of the buffer is 10000 bytes, and then 10000 bytes of data can be cached at maximum, in this embodiment, when the player is used for playing the first screen, the size of the frame group data can be represented by a code stream, and the code stream refers to the data flow in unit time, so when the frame group is stored in the buffer, the unit of the buffer can be converted into seconds, for example: the group size is 3s and the buffer length is 5 s.
In step 204, pre-stored picture group data is obtained.
The group of pictures includes the transmission order of each group of pictures and the length information of each group of pictures. The transmission order refers to the order in which the respective groups of pictures are transmitted into the player. The length information refers to the length of each group of pictures, and the unit is seconds.
A group of pictures is a set of consecutive pictures, a group of pictures comprising intra-coded frames, previous predicted frames and bi-directional interpolated frames, and a group of pictures comprising all frame data from a current key frame to a next key frame. Therefore, when transmitting a group of pictures, it is necessary to determine the transmission order of the group of pictures, i.e., the transmission order.
The transmission length refers to the length of a transmission picture group, for example: the length of the group of pictures is 5s, and the transmission length may be 1s, 2s, 5s, etc., as required.
And step 208, sending each picture group to a player of the terminal according to the sending length by adopting a frame skipping mode according to the sending sequence, and performing first-screen playing in the player.
The frame skipping refers to skipping to the next group of pictures for transmission when the transmission of the current group of pictures is stopped.
In the first-screen playing method, the frame skipping mode is adopted to greatly shorten the length of the frame group and effectively reserve the information of each frame group by acquiring the length information of the buffer area, the sequence of the frame groups and the length information of the frame groups, so that the first-screen second opening is realized.
In one embodiment, when the lengths of the picture groups are set, it is specifically adopted to set the frame segments of each picture group so that the sum of the lengths of the frame segments of each picture group is equal to the buffer length information, and the frame segment is taken as the transmission length of each picture group. In this embodiment, a frame segment refers to a segment in a group of pictures, and it should be noted that setting a frame segment is not simply extracting data from a group of pictures and saving the data as a frame segment. By the above mode, the total length of the picture group can be compressed to be equal to the length of the buffer area, and the length of the picture group is greatly shortened, so that the time delay of first-screen playing is reduced.
In a specific embodiment, the frame segment may be stored by extracting data in the group of pictures or by recording a position in the group of pictures. By adopting the mode of extracting data, the frame segment corresponding to the picture group can be directly sent when the picture group is sent, and the position recorded in the picture group is sent when the picture group is sent by adopting the mode of recording the position of the picture group.
In a specific embodiment, the frame segment is captured from left to right of the picture group, and the capturing may be to extract data, or to record the position of the frame segment in the picture group by capturing the head and tail data. From left to right, it is referred to as the head of the recording frame starting from the head of the group of pictures. For example: the length of the group of pictures is 5s, the frame segment is 3s, and then the first 3s of the group of pictures is intercepted.
In one embodiment, as shown in fig. 3, an exemplary flowchart of the step of setting frame segments is provided, which specifically includes the following steps:
In step 310, the frame segments of the current group of pictures are set so that the sum K of the frame segments of the current group of pictures and the frame segments of the previous group of pictures is smaller than the length S of the buffer.
In step 312, the frame segments of the current group of pictures are set such that the sum K of the frame segments of the current group of pictures and the frame segments of the previous group of pictures is equal to the buffer length S.
For step 304, the sum of the length of the current group of pictures and the frame segments of the previous group of pictures means that the total length of the frame segments selected by all groups of pictures before the current group of pictures is summed with the length of the current group of pictures in terms of the sending order. For example, if the previous picture group includes a first picture group and a second picture group, the length of the frame segment of the first picture group is 2s, the length of the frame segment of the second picture group is 1s, the current picture group is the third picture group, and the length of the picture group is 3s, the sum of the length of the current picture group and the frame segment of the previous picture group is 6 s.
In step 308, whether the sum of the lengths of the subsequent groups is greater than 0 is described in the above embodiment, if there are 6 groups, the length of the fifth group is 0, and the length of the sixth group is 0, then the sum of the lengths of the subsequent groups is equal to 0.
In another embodiment, when sending the group of pictures, the specific steps are as follows: and sequentially sending the picture groups according to the sending length and the sending sequence of the frame segments, judging whether the sending length of the current picture group is reached, if so, sending the next picture group in a frame skipping mode until the picture groups are sent to a player of the terminal. In this embodiment, the length of the frame group can be reduced by frame skipping, so as to reduce the delay of the first screen playing.
The present invention will be described below with reference to a specific example.
In one embodiment, the first screen playing method is performed as follows.
And S1, the server configures and caches two picture groups, and the length of the cache area for acquiring the terminal is S.
And S2, receiving a first screen data request sent by the terminal.
S3, judging whether the total length of the group of pictures gop1 and gop2 is larger than the length S of the buffer area, if not, jumping to S4, and if so, jumping to S5.
And S4, sending the picture group gop1 and the picture group gop2 to the terminal, and storing the picture group gop1 and the picture group gop2 in a buffer area of the terminal.
S5, if the length of the group of pictures gop1 is 0, sending data of the group of pictures gop2 with the length equal to S, and the length of the group of pictures gop2 with the length equal to 0, sending data of the group of pictures gop1 with the length equal to S, wherein both the gop1 and the gop2 are larger than zero, sending front part data of the gop1, then skipping to the gop2, and sending front part data of the gop2 to ensure that the sum of the two data is equal to S.
It should be understood that although the steps in the flowcharts of fig. 2 and 3 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows.
