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.
Before explaining the embodiments of the present application in detail, the application scenarios related to the embodiments of the present application are explained first.
In real life, a user usually plays a media file on a terminal, for example: video or audio is played on a terminal, but in the playing process, due to the influence of factors such as network speed, etc., the played media file may be jammed, for example: the stuck phenomenon occurs in a key part of a melody or a plot passage of a media file, and the stuck phenomenon greatly affects the user experience.
Based on the above scenario, embodiments of the present application provide a method for playing a media file, so as to reduce the possibility of stuttering when playing a key part of a melody or a plot paragraph of the media file, thereby improving user experience.
Fig. 1 is a flowchart illustrating a method of playing a media file according to an exemplary embodiment of the present application. As shown in fig. 1, the method for playing a media file includes the following steps:
The target paragraph is a paragraph which is closest to and behind the currently played paragraph in time sequence, the plurality of paragraphs are adjacent in time sequence, and the plurality of paragraphs are obtained by dividing the media file based on the content.
In summary, according to the playing method of the media file provided in the embodiment of the present application, by obtaining the pause possibility value of the target paragraph and pausing the playing of the target paragraph at the start position of the target paragraph when the pause possibility value is greater than the preset threshold, compared with the related art, the playing of the entire target paragraph can be paused when the pause possibility of the target paragraph is high, thereby effectively reducing the possibility of the pause when playing the melody or the key part of the scenario paragraph of the media file, and further improving the user experience.
Fig. 2A is a flowchart illustrating a method of playing a media file according to another exemplary embodiment of the present application. The method can be applied to a terminal and a server, and the method is described in the embodiment of the present application by taking the application of the method to the terminal as an example, as shown in fig. 2A, the method for playing a media file may include the following steps:
in step 201, a target paragraph is determined from a plurality of paragraphs included in a media file.
The target paragraph is a paragraph which is closest to and behind the currently played paragraph in time sequence, the paragraphs are adjacent in time sequence, and the paragraphs are obtained by dividing the media file based on the content. For example: at least one cut point may be determined in the media file based on the content of the media file, and the at least one cut point may divide the media file into a plurality of chronologically sequentially adjacent chapters.
In practical implementation, the implementation process of step 201 may include: determining a currently played paragraph according to the current playing progress of the media file, and determining a target paragraph from a plurality of paragraphs from a target time corresponding to the currently played paragraph, wherein the time length from the target time to the ending position of the currently played paragraph is greater than a preset time length threshold value.
Wherein, this preset duration threshold value can be set according to actual conditions, for example: the preset duration threshold may be determined according to time factors such as processing time consumed for determining the stuck possible value of the target paragraph, so that the time for pausing the playing of the target paragraph does not exceed the time corresponding to the start position of the target paragraph, thereby ensuring that the playing of the target paragraph can be paused at the start position of the target paragraph when the stuck possible value is greater than the preset threshold. Also, the preset duration threshold may be represented by time, for example: the preset time threshold may be 2 seconds, or the preset time threshold is represented by the playing progress of the media file, for example: the preset duration threshold may be set to a duration corresponding to 10% of the remaining playing progress of the currently playing paragraph.
For example, assume that the media file is a video file, the video file is divided into 5 paragraphs that are sequentially adjacent in time sequence according to the content of the scenario, and the 5 paragraphs are sequentially: paragraph 1, paragraph 2, paragraph 3, paragraph 4, paragraph 5, and the currently playing paragraph is paragraph 3, the time at the termination position of the currently playing paragraph is 23 minutes and 12 seconds, and the preset time threshold is 2 seconds, then the target paragraph can be determined from the 5 paragraphs from the target time 23 minutes and 10 seconds, and paragraph 4 is determined as the target paragraph.
It should be noted that, when the step 201 is executed by the server, the server may store related information of the media file, and when a target paragraph needs to be determined from a plurality of paragraphs included in the media file, an obtaining request for obtaining play progress information of a currently played paragraph may be sent to the terminal that plays the media file, after receiving the obtaining request, the terminal may send an obtaining response carrying the play progress information of the currently played paragraph to the server, and after receiving the obtaining response, the server may determine the target paragraph according to the play progress information of the currently played paragraph carried by the server.
In practical implementation, the implementation process of this step 202 may be: during the playing process of the media file, determining the pause possible value of the target paragraph in real time according to the target paragraph determined in step 201; alternatively, the implementation process of step 202 may also be: the method comprises the steps of determining the pause possible value of each paragraph in a media file in advance, establishing a corresponding relation according to each paragraph and the pause possible value corresponding to each paragraph, storing the corresponding relation in a memory, and inquiring the corresponding relation between the preset paragraph and the pause value when the pause possible value of the target paragraph needs to be acquired so as to determine the pause possible value of the target paragraph.
Optionally, as an implementation manner of determining the katon possible value of the target paragraph, the process may include: and acquiring the state data of the media file, and predicting the katon possible value of the target paragraph based on the state data of the media file.
When predicting the katton likelihood of the target paragraph, the state data of the media file may be input into the prediction model to obtain the katton likelihood of the target paragraph output by the prediction model.
Wherein the status data may include: at least one of unbuffered flow, historical buffered rate curve, historical stuck times and historical stuck duration corresponding to the target paragraph. The prediction model may be a long short-Term Memory (LSTM) model, a Radial Basis Function (RBF) neural network, a Logistic Regression (LR) model, a Bayesian (Bayesian) model, or the like.
It should be noted that before step 202 is executed, a database may be established in the terminal or the server, and the database stores state data of a historical buffering rate curve, a historical pause number, a historical pause duration, and the like of the media file, so as to obtain a pause possible value of the target paragraph according to the state data.
In step 203, when the katon probability value is greater than the preset threshold, the target paragraph is paused to be played at the start position of the target paragraph.
When the stuck possible value of the target paragraph is greater than the preset threshold, if the target paragraph continues to be played in the current state, the target paragraph is likely to be stuck, and at this time, the target paragraph may be paused at the start position of the target paragraph to avoid the stuck during the playing of the key part of the melody or scenario paragraph of the target paragraph. And after the target segment is paused, the terminal may display information for prompting the user to wait.
Wherein, this preset threshold value can be set up according to actual need, for example: the preset threshold may be set to 80%, i.e. when the katon probability value is greater than 80%, the target paragraph is paused at its start position.
It should be noted that, when the above steps 201 and 202 are executed by the server, when the step 203 is executed, the server may send the obtained stuck possible value to the terminal, and the terminal may determine whether the stuck possible value is greater than a preset threshold according to the stuck possible value, and execute whether to pause playing the target paragraph at the start position of the target paragraph according to the determination result; alternatively, the server may determine whether the stuck possible value is greater than a preset threshold according to the stuck possible value, and send an instruction to pause playing the target paragraph to the terminal when the stuck possible value is greater than the preset threshold, so that the terminal pauses playing the target paragraph at the start position of the target paragraph.
And step 204, after the preset time length of the current time, executing the step of judging whether the target paragraph is played.
Optionally, after the target paragraph is paused, the step of determining whether to resume playing the target paragraph may be executed after a preset time period, where the implementation manner of determining whether to resume playing the target paragraph may include the following two implementation manners:
as shown in fig. 2B, a first implementation manner of determining whether to resume playing the target paragraph may include:
After the preset duration of the current time, since the state data (e.g., the unbuffered traffic corresponding to the target paragraph) of the media file has changed, the possible stuck value of the target paragraph may also change, at this time, the possible stuck value of the target paragraph may be obtained again, and when the possible stuck value is not greater than the preset threshold, the target paragraph may be played.
The implementation process of obtaining the katon possible value of the target paragraph again may refer to the implementation process of step 202, which is not described herein again.
As shown in fig. 2C, a second implementation manner of determining whether to resume playing the target paragraph may include:
And 2042b, when the unbuffered flow is smaller than the preset flow threshold, playing the target paragraph.
After the preset duration of the current time, the unbuffered flow corresponding to the target paragraph may have changed, and the changed unbuffered flow may not cause the target paragraph to be stuck during playing, at this time, the unbuffered flow corresponding to the target paragraph may be obtained, and when the unbuffered flow is smaller than the preset flow threshold, the target paragraph is played.
It should be noted that the preset duration and the preset flow threshold in step 204 may be set according to actual needs, for example: the preset time period may be set to 1 second, and the preset flow threshold may be set to 5% of the total flow corresponding to the target segment, which is not specifically limited in the embodiment of the present application.
In summary, according to the playing method of the media file provided in the embodiment of the present application, by obtaining the pause possibility value of the target paragraph and pausing the playing of the target paragraph at the start position of the target paragraph when the pause possibility value is greater than the preset threshold, compared with the related art, the playing of the entire target paragraph can be paused when the pause possibility of the target paragraph is high, thereby effectively reducing the possibility of the pause when playing the melody or the key part of the scenario paragraph of the media file, and further improving the user experience.
