Detailed ways

In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

Before explaining the embodiments of the present application in detail, the application scenarios involved in the embodiments of the present application are explained first.

In real life, users usually play media files on the terminal, for example: playing video or audio on the terminal, but during the playback process, due to the influence of network speed and other factors, the played media files may appear stuck. For example, if the melody of the media file or the key part of the plot segment is stuck, the stuck phenomenon will greatly affect the user experience.

Based on the above scenario, an embodiment of the present application provides a method for playing a media file, so as to reduce the possibility of jamming when playing a key part of a melody or a plot paragraph of a media file, thereby improving user experience.

FIG. 1 is a flowchart of a method for playing a media file according to an exemplary embodiment of the present application. As shown in Figure 1, the method for playing the media file includes the following steps:

Step 101: Determine a target paragraph from a plurality of paragraphs included in the media file.

Wherein, the target paragraph is the paragraph closest to the current playing paragraph in time sequence and located after the current playing paragraph, multiple paragraphs are adjacent in sequence in time sequence, and the multiple paragraphs are obtained by dividing the media file based on the content.

Step 102: Obtain the possible stall value of the target paragraph.

Step 103 , when the possible stall value is greater than the preset threshold, pause the playback of the target segment at the start position of the target segment.

To sum up, the method for playing a media file provided by the embodiment of the present application obtains the possible stall value of the target paragraph, and when the stall probability value is greater than the preset threshold, pauses the playback of the target segment at the starting position of the target paragraph. Compared with the related art, the paragraph can pause the playback of the entire target paragraph when the target paragraph has a high probability of being stuck, which effectively reduces the possibility of freezing when playing the melody of the media file or the key part of the plot paragraph. Thereby, the user experience is improved.

FIG. 2A is a flowchart of a method for playing a media file according to another exemplary embodiment of the present application. The method can be used for both terminals and servers. The embodiment of the present application takes the method applied to a terminal as an example to describe it. As shown in FIG. 2A , the method for playing a media file may include the following steps:

Step 201, determining a target paragraph from a plurality of paragraphs included in the media file.

Wherein, the target paragraph is the paragraph closest to the currently playing paragraph in time sequence and located after the current playing paragraph, the plurality of paragraphs are adjacent in sequence in time sequence, and the plurality of paragraphs are obtained by dividing the media file based on the content. For example, at least one demarcation point may be determined in the media file according to the content of the media file, and the at least one demarcation point may divide the media file into a plurality of segments that are adjacent in sequence in time sequence.

In actual implementation, the implementation process of this step 201 may include: determining the current playing paragraph according to the current playing progress of the media file, starting from the target time corresponding to the current playing paragraph and determining the target paragraph from the plurality of paragraphs, and the target time to the current playing paragraph. The duration at the termination position of is greater than the preset duration threshold.

The preset duration threshold can be set according to the actual situation. For example, the preset duration threshold can be determined according to time factors such as the processing time taken to determine the possible value of the target segment being stuck, so that the time for pausing the playback of the target segment does not exceed The time corresponding to the starting position of the target paragraph, thereby ensuring that when the possible value of the freeze is greater than the preset threshold, the target paragraph can be paused at the starting position of the target paragraph. In addition, the preset duration threshold may be represented by time, for example, the preset duration threshold may be 2 seconds, or the preset duration threshold may be represented by the playback progress of the media file, for example, the preset duration threshold may be set to the currently playing segment The remaining playback progress is 10% of the corresponding duration.

For example, assuming that the media file is a video file, the video file can be divided into 5 paragraphs that are adjacent in time sequence according to the content of the plot, and the 5 paragraphs are: paragraph 1, paragraph 2, paragraph 3, paragraph 4 and paragraph. 5. The current playback segment is segment 3, the time at the end position of the current playback segment is 23 minutes and 12 seconds, and the preset duration threshold is 2 seconds, then it can start from the target time 23 minutes and 10 seconds from the 5 segments. Identify the target paragraph, and identify paragraph 4 as the target paragraph.

It should be noted that when step 201 is executed by the server, the server may store relevant information of the media file. When the target paragraph needs to be determined from multiple paragraphs included in the media file, the server may send a message to the terminal that plays the media file. In order to obtain the acquisition request for the playback progress information of the currently playing segment, after receiving the acquisition request, the terminal can send the acquisition response carrying the playback progress information of the currently playing segment to the server. The playback progress information of the currently playing segment determines the target segment.

Step 202: Obtain the possible stall value of the target paragraph.

In actual implementation, the implementation process of this step 202 can be as follows: during the playback process of the media file, according to the target segment determined in step 201, the possible value of the target segment is determined in real time; or, the implementation process of this step 202 is also It can be: predetermine the possible value of the freeze of each paragraph in the media file, establish a corresponding relationship according to the possible value of the freeze corresponding to each paragraph and each paragraph, and store the corresponding relationship in the memory, when the target needs to be obtained. When the possible stall value of the paragraph is found, the corresponding relationship between the preset paragraph and the stall value can be queried to determine the possible stall value of the target paragraph.

Optionally, as an achievable way of determining the possible stall value of the target segment, the process may include: acquiring state data of the media file, and predicting the possible stall value of the target segment based on the state data of the media file.

When predicting the possible freezing value of the target paragraph, the state data of the media file may be input into the prediction model, so as to obtain the possible freezing value of the target paragraph output by the prediction model.

Wherein, the status data may include: at least one of unbuffered traffic corresponding to the target paragraph, a historical buffering rate curve, the number of times of historical freezes, and the duration of historical freezes. Moreover, the prediction model can be a Long Short-Term Memory (LSTM) model, a Radial Basis Function (RBF) neural network, a Logistic Regression (LR) model, and a Bayesian (Bayesian) model. models, and other predictive models.

It should be noted that, before step 202 is executed, a database can be established in the terminal or server, and the database stores the historical buffer rate curve of the media file, the number of times of historical freezes, and the duration of historical freezes and other state data, so as to facilitate according to the data. The state data gets the possible value of the freeze of the target paragraph.

Step 203 , when the possible stall value is greater than the preset threshold, pause the playback of the target segment at the start position of the target segment.

When the possible freeze 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. At this time, the playback can be paused at the starting position of the target paragraph. the target passage to avoid stuttering when playing the key part of the melody or plot passage of the target passage. Moreover, after pausing the playback of the target segment, the terminal may display information for prompting the user to wait.

The preset threshold can be set according to actual needs. For example, the preset threshold can be set to 80%, that is, when the possible stall value is greater than 80%, the target segment is paused at the starting position of the target segment.

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 stall possible value to the terminal, and the terminal may judge the stall probability according to the stall probability value. Whether the value is greater than the preset threshold, and whether to pause the playback of the target segment at the starting position of the target segment according to the judgment result; When the possible stall value is greater than the preset threshold, an instruction instruction for pausing playback of the target segment is sent to the terminal, so that the terminal pauses the playback of the target segment at the start position of the target segment.

Step 204: After the preset duration at the current moment, the step of judging whether to play the target paragraph is performed.

Optionally, after pausing the playback of the target paragraph, the step of judging whether to resume playing the target paragraph can also be performed after a preset duration, wherein the implementation of the judgment on whether to resume the playing of the target paragraph can include the following two implementations:

As shown in FIG. 2B , the first achievable manner of judging whether to resume playing the target segment may include:

Step 2041a: After the preset duration at the current moment, obtain the possible value of the freeze of the target paragraph again.

Step 2042a, when the possible value of the freeze is not greater than the preset threshold, play the target paragraph.

After the preset duration at the current moment, since the state data of the media file (for example, the unbuffered traffic corresponding to the target paragraph) has changed, the possible value of the freeze of the target paragraph will also change accordingly. At this time, you can Obtain the possible freezing value of the target segment again, and play the target segment when the possible freezing value is not greater than the preset threshold.

Wherein, the implementation process of obtaining the possible stall value of the target paragraph again may refer to the implementation process of step 202, which will not be repeated here.

As shown in Figure 2C, the second achievable manner of judging whether to resume playing the target segment may include:

Step 2041b, after a preset duration at the current moment, obtain the unbuffered traffic corresponding to the target paragraph.

Step 2042b, when the unbuffered traffic is less than the preset traffic threshold, play the target paragraph.

After the preset duration at the current moment, the unbuffered traffic corresponding to the target segment may have changed, and the changed unbuffered traffic may no longer cause the target segment to freeze during playback. At this time, the corresponding target segment can be obtained. the unbuffered traffic, and play the target segment when the unbuffered traffic is less than the preset traffic threshold.

It should be noted that both the preset duration and the preset flow threshold in step 204 can be set according to actual needs. For example, the preset duration can be set to 1 second, and the preset flow threshold can be set to the corresponding target paragraph. 5% of the total flow, which is not specifically limited in this embodiment of the present application.

To sum up, the method for playing a media file provided by the embodiment of the present application obtains the possible stall value of the target paragraph, and when the stall probability value is greater than the preset threshold, pauses the playback of the target segment at the starting position of the target paragraph. Compared with the related art, the paragraph can pause the playback of the entire target paragraph when the target paragraph has a high probability of being stuck, which effectively reduces the possibility of freezing when playing the melody of the media file or the key part of the plot paragraph. Thereby, the user experience is improved.
