Thus, the following detailed description of the embodiments of the invention, as 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 made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.
In order to enable those skilled in the art to use the present application, the following embodiments are presented in connection with a specific application scenario of "online education, online lectures". It will be apparent to those having ordinary skill 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 present application. Although the present application is primarily described in the context of video online live lessons, it should be understood that this is but one exemplary embodiment.
One aspect of the present application relates to a video playback method. According to the method, the video to be played can be positioned according to the video playing progress to realize pseudo live broadcast, the blocking rate is reduced, the phenomenon of video packet loss is avoided, and the video stability is improved.
It is noted that, before the application is filed in the application, the traditional pseudo live broadcast mode is to record live broadcast video in advance, when the live broadcast time point is reached, the live broadcast push server pushes the video stream to the client through a live broadcast protocol such as RTMP, and the user watches the video through the live broadcast device.
However, the video playing method provided by the application discards the scheme of traditional RTMP push stream, and adopts a mode of determining the video playing progress to position and play the video, thereby improving the video stability and reducing the broadband cost.
Referring to fig. 1, a flowchart of a video playing method according to an embodiment of the present invention is shown. The method is applied to a video live client, namely, the video playing method is a method for controlling the playing progress of a video to be played at the video live client, and the specific flow is as follows:
step S101, a video playing request for a video to be played is sent to a server.
In an optional embodiment, the video playing method can be applied to scenes such as online education, online teaching, online listening and the like, and corresponding videos can be played in the scenes in a live broadcast mode.
In addition, the corresponding video can be played in the scene in a pseudo live broadcast mode. Here, the pseudo live broadcast refers to playing a video recorded in advance in a live broadcast mode. At this time, the video to be played may refer to a pseudo live video. For example, the pseudo live video is pre-stored in a server, the time when the pseudo live video starts is recorded in the server, and the server sends corresponding description files according to the time when different video live clients enter a live interface, wherein the description files are used for determining the video live progress of the different video live clients, so that the effect of pseudo live video is achieved. For example, the starting playing time of the pseudo live video is 9 am, if a video live client enters the live interface at 9 am at 5 am and sends a video playing request, the video live client can directly start playing from the 5 th minute of the pseudo live video, that is, the videos seen by all video live clients are synchronous.
For example, the video live client may first enter a live interface that includes a plurality of live programs (e.g., a plurality of online courses), and when a user selection of any of the plurality of live programs is received, a video play request is generated and sent to the server.
Here, any selected direct-play program is the video to be played, and the generated video playing request is the video playing request aiming at the video to be played.
Step S102, a description file of the video to be played fed back by the server in response to the video playing request is received from the server. Here, the description file may include a storage address of the video to be played so that the video stream applied to the video live client can acquire the video to be played based on the storage address.
For example, the video playing request may carry relevant information of the video to be played, where the relevant 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 related information of the video to be played, and determines a description file of the video to be played based on the related information.
That is, after the live video client enters live video, the live video client sends a video playing request for the 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 timestamp may refer to the total seconds from the greenwich time 1970, 01, 00 minutes, 00 seconds (Beijing time 1970, 01, 08, 00 minutes, 00 seconds) to the current live time, and the play start timestamp 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 for a mathematical course of online education, the play start timestamp 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 the current live broadcast 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.
Step S104, the video stream of the video to be played is obtained according to the storage address, and the video is played from the current playing progress.
In the video playing method, in the playing process, 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 for correcting the current playing progress of the video to be played by the video live client, that is, the video correction parameter is determined based on the judging 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, the server stores the pre-recorded video to be played, and records the video playing time (i.e., the playing progress) of the video to be played from the time when the video to be played starts to be played. When the video live client enters live broadcast at a certain moment, the video live client acquires the current playing progress of the video to be played from the server, and the video live client positions the video to be played to the progress to play the video.
Referring to fig. 2, a flowchart of another video playing method provided in an 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, a description file of the video to be played fed back by the server in response to the video playing request is received from the server. Here, the description file includes a storage address of the video to be played.
Step S203, determining the current playing progress of the video to be played.
Step S204, the video stream of the video to be played is obtained according to the storage address, and the video is played 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 will not be described in detail.
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 at the on-demand server, so that a video stream of the video to be played is obtained according to the storage address for playing.
For various courses in online education, the server packages video to be played (pre-recorded pseudo live video) into video-on-demand streams during playing, and the video-on-demand streams are actively pulled by the video live client to achieve the same live effect as that of traditional RTMP live broadcast. The video live client starts to preload the video before live broadcasting starts, when a user starts to watch, the actual video is preloaded, the video can be watched directly without any loading process, so that the opening time of a first frame of the video is almost 0 millisecond, the playing process can flexibly buffer the length, the problem of pseudo live broadcasting delay is avoided, and the phenomenon of blocking is easier to avoid.
In step S205, during the playing process, video correction parameters are determined at predetermined time intervals to correct the current playing progress of the video to be played based on the video correction parameters.
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 a 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 value between the current timestamp and the live start timestamp, wherein the current timestamp and the play start timestamp (i.e., the live start timestamp) of the video to be played can be obtained by analyzing the description file obtained from the server by the live video client for the first time, the live video client records the difference value between the current timestamp of the server and the local current timestamp of the live video client, and then the theoretical playing progress is calculated without obtaining from the server, and the sum value of the difference value 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 value of the predetermined time interval may be set as needed by those skilled in the art, which is not limited thereto. In an embodiment, the video correction parameter δ is determined once every 5S to determine whether the current playing progress of the video to be played needs to be corrected.
Step S206, judging whether the video correction parameter is larger than the set time threshold.
If the video correction parameter is greater than the set time threshold, step S206 is performed: and correcting the current playing progress of the video to be played based on the video correction parameters.
As an example, in this step, it may be determined whether the time difference between the actual playing progress of the video to be played and the theoretical playing progress 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 to be a new playing progress, and the new playing progress is positioned to the playing progress for playing. 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 parameters, for example, the sum of the current playing progress and the video correction parameters is determined to be a new playing progress, and the new playing progress is positioned to the playing progress for playing.
For example, the current video playing progress is recorded, and the step S203 is executed in a return manner, so that the live video client obtains a new start position of the video stream according to the current playing progress time stamp and the data position information (the MP4 format video stream) stored in the video, corrects the new start position, and redraws the new video stream from the server.
As an example, the set time threshold may be set to 5S, but the present application is not limited thereto, and the magnitude of the set time threshold may be set as needed by those skilled in the art, which 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 modified; if delta is larger than 5S, the video live client obtains a new starting position of the video stream according to the current playing progress time stamp and the time stamp and data position information (MP 4 format video stream) stored in the video head, and the new video stream is pulled again from the server, so that the time progress of the video to be played is corrected according to the parameter.
Because the current live progress is inconsistent with the expected pseudo live progress due to network or other reasons, video correction parameters are determined at preset time intervals in the playing process, and the correction parameters are compared with a set time threshold value, so that live progress verification is performed.
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 corrected, and the step S207 is continuously executed: and judging whether the video to be played is finished or not.
Here, whether the video to be played is ended may be broken 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, the video to be played is indicated to be played to be finished, 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, the video to be played is indicated to be not played to be finished.
If the video playing to be played is not finished, the step S203 is executed again to continue playing the video.
If the video to be played has been played, the playing of the video is ended, for example, the video live client may exit live.
