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.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the 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.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
In order to enable those skilled in the art to use the present disclosure, the following embodiments are given in conjunction with a specific application scenario "online education, online lecture listening". It will be apparent to those skilled in the art that the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the application. Although the present application is described primarily in the context of a video online live session, it should be understood that this is merely one exemplary embodiment.
One aspect of the present application relates to a video playback method. The method can position the video to be played according to the video playing progress to realize pseudo live broadcast, reduces the pause rate, avoids the phenomenon of video packet loss and improves the video stability.
It is worth noting that before the application is provided, the traditional pseudo live broadcast mode is that live broadcast video is recorded in advance, when the live broadcast time point is reached, a live broadcast stream pushing server pushes video stream to a client through live broadcast protocols such as RTMP, and a user watches the video through a live broadcast device.
However, the video playing method provided by the application abandons the traditional RTMP stream pushing scheme, adopts a mode of determining the video playing progress to position and play the video, improves the video stability and reduces the broadband cost.
Fig. 1 is a flowchart of a video playing method according to an embodiment of the present invention. The method is applied to a live video client, namely, the video playing method is a method for controlling the playing progress of a video to be played at the live video client, and the specific flow is as follows:
step S101, sending a video playing request aiming at a video to be played to a server.
In an optional embodiment, the video playing method can be applied to scenes such as online education, online teaching, online lecture listening and the like, and corresponding videos can be played in the scenes in a live broadcast mode.
Besides, the corresponding video can be played in a pseudo-live mode in the scene. Here, pseudo live broadcasting refers to broadcasting a video recorded in advance in a live broadcasting manner. At this time, the video to be played may refer to a pseudo live video. For example, a pseudo live broadcast video is pre-stored in a server, the time when the pseudo live broadcast starts is recorded in the server, the server sends a corresponding description file according to the time when different live broadcast clients enter a live broadcast interface, and the description file is used for determining the live broadcast progress of the different live broadcast clients, so that the pseudo live broadcast effect is achieved. For example, the start playing time set by the pseudo live video is 9 am, and if a live video client enters a live interface at 9 am and 5 min, and sends a video playing request, the live video client can start playing directly from the 5 th min of the pseudo live video, that is, videos seen by all live video clients are synchronized.
Illustratively, a live video client may first enter a live interface including a plurality of live programs (e.g., a plurality of online courses), and when receiving a selection of any live program of the plurality of live programs from a user, generate a video play request, and send the video play request to a server.
Here, any selected live program is a video to be played, and the generated video playing request is a video playing request for the video to be played.
Step S102, receiving a description file of the video to be played, which is fed back by the server in response to the video playing request, from the server. Here, the description file may include a storage address of the video to be played, so that the application to the live video client can obtain a video stream of the video to be played based on the storage address.
For example, the video playing request may carry related information of a video to be played, where the related information may include, but is not limited to, one or more of the following: the name of the video to be played and the content label of the video to be played.
After receiving the video playing request, the server analyzes the video playing request to obtain the relevant information of the video to be played, and determines the description file of the video to be played based on the relevant information.
That is to say, after the live video client enters live broadcasting, the live video client sends a video playing request for a video to be played to the server, and then the live video client receives a description file of the video to be played, which is fed back by the server in response to the video playing request.
Step S103, determining the current playing progress of the video to be played.
In the embodiment of the present application, the description file may further include a current timestamp and a play start timestamp of the video to be played, in addition to the storage address of the video to be played.
Here, the current time stamp may refer to the total number of seconds from the greenwich mean time 1970, 01, 00 hours 00 minutes 00 seconds (the beijing time 1970, 01, 08 hours 00 seconds) to the current live time, and the play start time stamp of the video to be played may refer to the start time of the video to be played, for example, when the video to be played is a learning video of a mathematical course of online education, the play start time stamp of the video to be played may refer to the start time of the learning video. The current playing progress of the video to be played is also the current live broadcasting progress.
In this case, in this step, a time difference between the current time stamp and the play start time stamp of the video to be played may be determined, and the time difference is determined as the current play progress of the video to be played.
And step S104, acquiring the video stream of the video to be played according to the storage address, and playing the video stream from the current playing progress.
According to the video playing method, in the playing process, the video correction parameters are determined at preset time intervals, and the current playing progress of the video to be played is corrected based on the video correction parameters.
Here, the video correction parameter is used to correct the current playing progress of the video to be played by the live video client, that is, the video correction parameter is determined based on a determination result of whether the actual playing progress of the video to be played is consistent with the theoretical playing progress, so as to correct the current playing progress of the video to be played.
In this embodiment, a video to be played, which is recorded in advance, is stored in the server, and the video playing time (i.e., the playing progress) of the video to be played is recorded from the moment when the video to be played starts to be played. When the live video client enters live broadcasting at a certain moment, the live video client acquires the current playing progress of the video to be played from the server, and the live video client positions the video to be played to the progress to play the video.
Referring to fig. 2, a schematic flow chart of another video playing method provided in the embodiment of the present application is shown, where the method may be executed by a live video client, and the specific execution process is as follows:
step S201, a video playing request for a video to be played is sent to a server.
Step S202, receiving the description file of the video to be played, which is fed back by the server in response to the video playing request, from the server. Here, the description file includes a storage address of a video to be played.
Step S203, determining the current playing progress of the video to be played.
And step S204, acquiring the video stream of the video to be played according to the storage address, and playing the video stream from the current playing progress.
The descriptions of steps S201 to S204 may refer to the descriptions of steps S101 to S104 shown in fig. 1, and the same technical effects can be achieved, which are not described in detail herein.
For example, the description file may be parsed to obtain a storage address of the video to be played, where the storage address is located in the on-demand server, so as to obtain the video stream of the video to be played according to the storage address for playing.
Illustratively, for various courses in online education, during playing, a server encapsulates a video to be played (a prerecorded pseudo live video) into an on-demand video stream, and then a live video client actively pulls the on-demand video stream, so that the live effect same as that of the traditional RTMP live broadcast is realized. The live video client starts to preload videos before live broadcast starts, when a user starts to watch the videos, the actual videos are preloaded, the videos can be watched directly without any loading process, so that the opening time of the first frame of the videos is almost 0 millisecond, the length of the playing process can be flexibly cached, the problem of pseudo live broadcast delay is avoided, and the pause phenomenon is avoided more easily.
In step S205, in the playing process, the video correction parameter is determined at a predetermined time interval, so as to modify the current playing progress of the video to be played based on the video correction parameter.
In an alternative embodiment, the video correction parameters (as represented by δ) may be determined by: determining the actual playing progress of the video to be played; determining the theoretical playing progress of a video to be played; and determining the absolute value of the time difference between the actual playing progress and the theoretical playing progress of the video to be played as a video correction parameter.
Here, the actual playing progress of the video to be played is the live time progress recorded by the live video client, the theoretical playing progress is the difference between the current timestamp and the live starting timestamp, wherein the current timestamp and the playing starting timestamp (i.e., the live starting timestamp) of the video to be played can be obtained by parsing the description file acquired from the server for the first time from the live video client, the difference between the current timestamp of the server and the local current timestamp of the live video client is recorded by the live video client, the theoretical playing progress is not required to be acquired from the server after calculation, and the sum of the difference and the local current timestamp can be determined as the current timestamp.
As an example, the predetermined time interval may be set to 5S, but the present application is not limited thereto, and the numerical value of the predetermined time interval may be set by those skilled in the art as needed, and the present application is not limited thereto. In an embodiment, the video correction parameter δ is determined every 5S to determine whether the current playing progress of the video to be played needs to be corrected.
Step S206, determining whether the video correction parameter is greater than a predetermined time threshold.
If the video correction parameter is greater than the set time threshold, step S206 is executed: and modifying the current playing progress of the video to be played based on the video correction parameter.
As an example, in this step, it may be determined whether a time difference between an actual playing progress and a theoretical playing progress of the video to be played is greater than zero; if the time difference is greater than zero, the current playing progress of the video to be played is slowed down according to the video correction parameters, for example, the difference value between the current playing progress and the video correction parameters is determined as a new playing progress, and the new playing progress is positioned to be played. If the time difference is smaller than zero, the current playing progress of the video to be played is adjusted according to the video correction parameter, for example, the sum of the current playing progress and the video correction parameter is determined as a new playing progress, and the current playing progress is positioned to be played.
For example, the current video playing progress is recorded, and the process returns to step S203, so that the live video client obtains a new start position of the video stream according to the timestamp of the current playing progress, the timestamp stored in the video and the data position information (the video stream in the MP4 format), corrects the new start position, and pulls the new video stream from the server again.
As an example, the set time threshold may be set to 5S, but the application is not limited thereto, and the value of the set time threshold may be set by a person skilled in the art as needed, and the application is not limited thereto.
For the above listed example, if δ is not greater than 5S, the current playing progress of the video to be played is not corrected; if delta is larger than 5S, the live video client obtains a new start position of the video stream according to the current playing progress timestamp, the timestamp stored in the video header and the data position information (the video stream in the MP4 format), pulls the new video stream from the server again, and corrects the time progress of the video to be played according to the parameter.
Because the current live broadcast progress is inconsistent with the expected pseudo live broadcast progress due to network or other reasons, in the playing process, a video correction parameter is determined at a preset time interval, and the video correction parameter is compared with a set time threshold value, so that the live broadcast progress is checked.
If the video correction parameter is not greater than the set time threshold, the current playing progress of the video to be played is not modified, and step S207 is continuously executed: and judging whether the video to be played is played completely.
Here, whether the video to be played is played to the end may be interrupted based on the current playing progress of the video to be played and the total video duration of the video to be played. For example, if the difference between the total video duration of the video to be played and the current playing progress of the video to be played is zero, it indicates that the video to be played has been played, and if the difference between the total video duration of the video to be played and the current playing progress of the video to be played is not zero, it indicates that the video to be played has not been played.
If the video playing to be played is not finished, the process returns to step S203 to continue playing the video.
If the video broadcast to be played is already played, the video playing is ended, for example, the video live broadcast client can quit the live broadcast.
Based on the same inventive concept, a video playing apparatus corresponding to the video playing method shown in fig. 1 is also provided in the embodiments of the present application, and since the principle of the apparatus in the embodiments of the present application for solving the problem is similar to the service pushing method described above in the embodiments of the present application, the implementation of the apparatus may refer to the implementation of the method, and repeated details are not repeated.
