Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
Referring to fig. 1, a live playback method according to an embodiment of the present invention is applied to a server, and includes the following steps:
In this embodiment, the chat room message refers to the whole chat message published in the live broadcast process. The obtaining of the chat room message can start in the live broadcasting process or after the live broadcasting is completed.
In this embodiment, the absolute time of publication of each chat message needs to be converted into the relative time of publication, so as to further process the chat room messages and match the playback progress.
Wherein, the step 102 may specifically include the following steps:
acquiring a release timestamp of the chat message and a start timestamp of live broadcast;
and obtaining the relative issuing time according to the difference value of the issuing time stamp and the starting time stamp.
That is, the absolute time of successful delivery of a chat message is converted into a relative time of delivery, in which the timestamp of successful delivery of the chat message minus the timestamp of start of live broadcast, for example, live broadcast is started at 21.
And 103, after the live broadcast is finished, segmenting the chat room messages according to the relative publishing time to obtain segmented information, wherein the segmented information comprises the segmented number, the time range of each segment, the message number of each segment and the start-stop message identification code of each segment.
In this embodiment, the relative time of publication based on the chat message is segmented, so that the memory pressure is smaller and the response is faster when the terminal loads the chat message segment by segment. That is, when the terminal needs to watch the live broadcast playback, the terminal firstly calls an interface of the server to obtain the segment information of the chat message, the segment information comprises the segment number, the time range of each segment, the message number of each segment and the start-stop message identification code of each segment, the segment number is the number of segments into which all messages of the current live broadcast playback are divided, the time range of each segment is the time range span of each segment, the message number of each segment refers to the message number of each segment, and the start-stop message identification code of each segment is the start-stop chat message ID of each segment. And then the terminal calls an interface of a specific segment according to the requirement to acquire the chat message in a certain segment.
Wherein, step 103 may further include the following steps:
preprocessing chat room messages according to a time span threshold;
the preprocessed chat room messages are segmented according to the relative publication time and the fixed message quantity requirements.
In one embodiment, after each live broadcast is finished, the server segments the live broadcast chat messages according to a fixed number of messages. The step of preprocessing the chat room messages according to the time span threshold may be that when the messages are segmented, instant chat messages are highly concurrent, and the chat room messages should be processed in advance according to a certain rule, for example, some messages with low priority are discarded, or a part of the messages are intercepted according to an upper limit threshold, etc., so as to ensure that the time span of the messages of each segment is greater than a certain time length.
In addition to segmenting chat room messages according to a fixed number of messages, chat room messages may also be segmented according to a fixed time span, or the like.
And 104, responding to the playback operation of the live broadcast, sending the segmented information to the terminal, and sending the chat message corresponding to the segment to the terminal according to the playing time required by the playback operation, so that the terminal synchronously displays the multimedia information and the chat message according to the playing time required by the playback operation.
In the embodiment of the invention, after receiving the playback instruction of the live broadcast, the terminal acquires the chat message corresponding to the segment according to the segment information provided by the server and the required playing time of the playback operation, and can synchronously play the multimedia information and the chat message more quickly.
The embodiment of the invention is used for providing a chat message synchronous playback scheme with loose requirements on the live broadcast time length and the number of chat messages in the live broadcast. Due to the fact that the chat messages are segmented, under the condition that the total quantity of the related messages is large regardless of the duration of live broadcast, the method and the device are used for enabling the user to play the messages without feeling and without influencing the performance of the terminal.
Referring to fig. 2, a live playback method according to another embodiment of the present invention is applied to a terminal, and includes the following steps:
In the embodiment of the invention, after receiving the playback instruction of the live broadcast, the terminal acquires the segment information of the chat room message from the server.
In the embodiment of the invention, the chat message of the corresponding segment of the playing time is acquired, and the fast-response request of the live playback of the user can be quickly responded. Wherein, step 202 may further include the steps of:
judging whether the chat message of the corresponding segment exists in a local cache file in advance according to the required playing time; if yes, reading the chat message corresponding to the segment to the memory; if not, obtaining the chat message of the corresponding segment from the server, and writing the chat message obtained from the server into a local cache file.
Specifically, in the playing process, the terminal firstly judges whether the next message exists in a local cache file, if so, the message is read from the cache file to the memory, and if not, the back-end interface is called to obtain the message, the message is read to the memory, and the message is written into the cache file. Here, the cache file is written to avoid repeatedly calling the same interface for many times in a short time. Note that in order to display the message to the user at the correct time, the terminal needs to perform this operation x seconds in advance, which is flexibly determined according to the specific service scenario.
After step 202, the method may further include:
judging whether the message amount is too large according to the loaded chat messages;
if yes, removing the first preset time or the first preset number of chat messages from the memory according to the required playing time.
In the embodiment of the invention, if the message volume of live broadcast playback is larger, the terminal can remove the earlier message from the memory in order to optimize the performance, and the user reloads the previous message when sliding the chat list and wants to see the earlier message. The standard for leaving the messages may be to only keep the messages m seconds before the current playing time node, that is, to remove the chat messages within the first preset time from the memory, or to only keep the n messages closest to the current playing time node, that is, to remove the first preset number of chat messages from the memory. The first preset time and the first preset number can be set according to specific service conditions and the performance of the equipment.
In order to solve the problem that the synchronous playback of the chat messages and the multimedia information can not be realized in the existing network live broadcast, the embodiment of the invention carries out sectional processing on the chat room messages corresponding to the live broadcast through the server after the live broadcast, when the terminal needs to play back, the sectional chat messages corresponding to the required playing time are obtained according to the sectional information provided by the server, and the synchronous display of the multimedia information and the chat messages is realized.
