Based on the above-mentioned implementation environment shown in FIG. 1 , an embodiment of the present application provides a method for playing a multimedia file, taking the application of the method to a terminal as an example. As shown in FIG. 2 , the method provided by this embodiment of the present application may include the following steps 201 to 204 .

In step 201, a multimedia file to be played is acquired.

The embodiments of the present application do not limit the application scenarios of the method for playing a multimedia file, nor do they limit the method for acquiring a multimedia file to be played. For example, the method for playing a multimedia file can be applied to application scenarios such as an audiobook playing application or a webpage. In some embodiments, the multimedia file in this case may be an audio file. The user can choose to play the audio file corresponding to any audiobook in the application. Exemplarily, if the audio file selected by the user to play hits the cache, the terminal where the application program is located may acquire the corresponding audio file based on the cache in the terminal. Alternatively, if the cache is not hit, the terminal where the application program is located may obtain the corresponding audio file based on the server.

For another example, the method for playing a multimedia file may be applied to application scenarios such as an application program or a webpage for playing a movie and TV series. In some embodiments, the multimedia file in this case may be a video file. Users can choose to play any video file within the app. At this time, if the video file selected to be played by the user hits the cache, the terminal where the application program is located may acquire the corresponding video file based on the cache of the terminal. Alternatively, if the cache is not hit, the terminal where the application program is located may obtain the corresponding video file based on the server.

This embodiment of the present application does not limit the format of the multimedia file to be played. For example, the multimedia file may be an audio file, then the format of the multimedia file may be WAV (Waveform Audio, waveform audio) format, or the format of the multimedia file may be It is MP3 (Moving Picture Experts Group Audio Layer 3) format. For another example, the multimedia file may be a video file, then the format of the multimedia file may be AVI (Audio Video Interleaved, audio and video interleaved) format, or the format of the multimedia file may be MPEG ((Moving Picture Experts Group, Dynamic Image Experts Group) group) format.

In step 202, if the multimedia file is not played for the first time, at least one historical playing rate of the multimedia file and the historical playing times corresponding to the at least one historical playing rate are determined.

In an exemplary embodiment, the terminal or the server may store at least one historical playing rate of the multimedia file and the historical playing times corresponding to the at least one historical playing rate. The terminal can read the stored content, and if the content is empty, it can be considered that the multimedia file is played for the first time. On the contrary, it can be considered that the multimedia file is not played for the first time, and the terminal can obtain at least one historical playing rate of the multimedia file and the historical playing times corresponding to the at least one historical playing rate based on the read content.

In some embodiments, the multimedia file to be played is a multimedia file to be played by the first account, and the historical playback rate is at least one of the historical playback rate of the multimedia file played by the first account and the historical playback rate of the multimedia file played by the second account. The second account is at least one account other than the first account.

In a possible implementation, before the first account plays the multimedia file this time, the first account has played the multimedia file twice at 1.25 times the speed, and the historical playback rate of the multimedia file played by the second account includes 1.25 times the speed, 1.5x and 1.75x speed. The number of times the second user plays the multimedia file at 1.25 times is 1000 times, the times at 1.5 times the multimedia file is 200 times, and the times at which 1.75 times is used is 19 times.

In the above embodiment, when the historical playback rate is the historical playback rate of the multimedia file played by the first account, the historical playback rate is 1.25 times the speed, and the historical playback frequency corresponding to the historical playback rate is 2 times. When the historical playback rate is the historical playback rate of the multimedia file played by the second account, the historical playback rate is 1.25 times the speed, 1.5 times the speed and 1.75 times the speed. Among them, the number of historical playback times corresponding to 1.25 times is 1000 times, the number of times of historical playback corresponding to 1.5 times speed is 200 times, and the number of times of historical playback corresponding to 1.75 times speed is 19 times. When the historical playback rate is the historical playback rate of multimedia files played by the first account and the historical playback rate of multimedia files played by the second account, the historical playback rates are 1.25 times, 1.5 times, and 1.75 times. Among them, the number of historical playback times corresponding to 1.25x speed is 1002 times, the number of historical playback times corresponding to 1.5x speed is 200 times, and the number of historical playback times corresponding to 1.75x speed is 19 times.

This embodiment of the present application does not limit the types of playback rates that may be included in the historical playback rates, and the types of playback rates may be set based on experience or application scenarios. In a possible implementation, the application program or web page that plays multimedia files may provide options for multiple playback rates. For example, the options may include 0.5x speed, 1x speed, 1.5x speed and 2x speed, so the historical playback rate may include 0.5x, 1x, 1.5x and 2x.

In another possible implementation, a threshold range of the playback speed may be set (for example, the range may be 0.5 times speed to 2 times speed). Within the threshold range of the playback rate, the type of playback rate may be determined based on a reference step size, which may be set based on experience. For example, the reference step size may be 0.25. Therefore, within the threshold range of 0.5x to 2x, the historical playback rate may include 0.5x, 0.75x, 1x, 1.25x, 1.5x, 1.75x, and 2x.

This embodiment of the present application does not limit the representation of the at least one historical playback rate of the multimedia file and the representation of the historical playback times corresponding to the at least one historical playback rate. For example, the representation can be represented in the form of an array. Exemplarily, the representation of at least one historical playback rate of the multimedia file and the historical playback times corresponding to at least one historical playback rate may be (1000, 1.25), (200, 1.5), (19, 1.75), (10 , 0.75). Wherein, the second number in the brackets of the array is used to indicate the historical playback rate, and the first number in the brackets of the array is used to indicate the historical playback times corresponding to the historical playback rate. Therefore, the historical playback rate of the multimedia file includes 1.25 times speed, 1.5 times speed, 1.75 times speed and 0.75 times speed. The number of historical playbacks corresponding to 1.25x speed is 1000 times, the number of historical playback times corresponding to 1.5x speed is 200 times, the number of historical playback times corresponding to 1.75x speed is 19 times, and the number of historical playback times corresponding to 0.75x speed is 10 times.

In another possible implementation manner, at least one historical playback rate of the multimedia file and the historical playback times corresponding to the at least one historical playback rate may be represented in the form of strings. Exemplarily, the playback information of the multimedia file may be 01000125, 00200150, 00019175, 00010075. The last three characters of any character string are used to indicate the historical playback rate, and the first five characters of any character string are used to indicate the historical playback times corresponding to the historical playback rate. For example, the last three characters in the string of 01000125 are 125, so the historical playback rate indicated by this string is 1.25 times the speed; the first five characters in the string of 01000125 are 01000, so the historical playback rate indicated by this string is 01000 The corresponding historical playback times are 1000 times. Therefore, the historical playback rate of the multimedia file includes 1.25 times speed, 1.5 times speed, 1.75 times speed and 0.75 times speed. The number of historical playbacks corresponding to 1.25x speed is 1000 times, the number of historical playback times corresponding to 1.5x speed is 200 times, the number of historical playback times corresponding to 1.75x speed is 19 times, and the number of historical playback times corresponding to 0.75x speed is 10 times.

In step 203, in response to the historical playing times reaching the threshold in the historical playing times, the first playing rate is determined based on the historical playing rate corresponding to the historical playing times reaching the threshold.

This embodiment of the present application does not limit the threshold. For example, the threshold may be set as a positive number greater than zero (for example, the threshold may be 500). Therefore, the historical playback rate for which the corresponding number of historical playback times is greater than the set threshold value is the historical playback rate that reaches the threshold value.

Exemplarily, determining the first playback rate based on the historical playback rates corresponding to the historical playback times that have reached the threshold, including: if there are multiple historical playback times that have reached the threshold, dividing the number of historical playback rates corresponding to the multiple historical playback times that have reached the threshold. The average value is used as the first playback rate, or the highest historical playback rate among the historical playback rates corresponding to multiple historical playback times that have reached the threshold is used as the first playback rate.

In a possible implementation manner, there are multiple historical playing times reaching the threshold, and the average value of the historical playing rates corresponding to the multiple historical playing times reaching the threshold may be used as the first playing rate. For example, there are two historical playback rates corresponding to the number of historical playback times that reach the threshold, which are 1.5 times the speed and 2 times the speed respectively. Therefore, the first playback rate at this time may be the average of 1.5 times the speed and 2 times the speed, that is, 1.75 times the speed.

In another possible implementation, there are multiple historical playback times that have reached the threshold, and the historical playback rate corresponding to the historical playback times that have reached the threshold may be actively popped up for the user to choose. The first playback rate may be a historical playback rate actively selected by the user. The method for popping up the historical playback rate can be popped up in the form of a popup window, for example.

In another possible implementation, there are multiple historical playback times that have reached the threshold, and a historical playback rate that is closest to 1x speed among the historical playback rates corresponding to the multiple historical playback times that have reached the threshold may be used as the first playback rate . For example, there are two historical playback rates corresponding to the number of historical playback times that reach the threshold, which are 1.5 times the speed and 2 times the speed respectively. Therefore, the first playback rate at this time may be a historical playback rate closer to 1x speed among 1.5x speed and 2x speed, that is, 1.5x speed.

In another possible implementation manner, the highest historical playback rate among the historical playback rates corresponding to a plurality of historical playback times that have reached the threshold may be used as the first playback rate. For example, historical playback rates that have reached the threshold include 1.25x and 1.5x. The first playback rate at this time may be the highest historical playback rate among the 1.5-times speed and the 1.25-times speed, that is, the 1.5-times speed.

In another possible implementation manner, the historical playback rate corresponding to the historical playback number with the largest historical playback number among the multiple historical playback numbers that reach the threshold may be used as the first playback rate. For example, historical playback rates that have reached the threshold include 1.25x and 1.5x. Among them, the number of historical playback times corresponding to 1.25x speed is 1000 times, and the number of historical playback times corresponding to 1.5x speed is 1200 times. The first playback rate at this time may be 1.5 times the speed.

By setting the threshold, the accuracy of determining the first playback rate can be improved, the possibility of manually adjusting the playback rate is further reduced, the flexibility of the playback method of the multimedia file is improved, and the efficiency of adjusting the playback rate is improved.

In step 204, the multimedia file is played according to the first play rate.

Exemplarily, if the first playback rate is 1.25 times the speed, the multimedia file may be played at the playback rate of 1.25 times the speed.

In an exemplary embodiment, the method further includes: in response to the historical playing times that do not reach the threshold in the historical playing times, playing the multimedia file based on a default playing rate; or, if the multimedia file is played for the first time, playing the multimedia based on the default playing rate document.

This embodiment of the present application does not limit the default playback rate for acquiring the multimedia file. The default playback rate may be set based on experience or application scenarios, for example, the default playback rate of the multimedia file may be set to 1x speed. In response to that there is no historical playing times reaching the threshold in the historical playing times, or the multimedia file is being played for the first time, the multimedia file may be played at a speed of 1 times. For another example, the default playback speed of the multimedia file may be set to 1.25 times the speed. In response to that there is no historical playing times reaching the threshold in the historical playing times, or the multimedia file is being played for the first time, the multimedia file may be played at a speed of 1.25 times.

In an exemplary embodiment, after the multimedia file is played according to the first playback rate, the method further includes: in response to the playback rate of the multimedia file being adjusted from the first playback rate to the second playback rate, recording the second playback rate, and recording the second playback rate according to the second playback rate. The playback rate continues to play multimedia files.

In some embodiments, the playback rate of the multimedia file can be adjusted at any time during playback. For example, if the first playback rate is 1.25 times, the multimedia file is played for 10 seconds at a playback rate of 1.25 times, and the playback rate is adjusted to 1 times at the 10th second, then the second playback rate is 1 times, the Multimedia files can be played at a playback rate of 1x from the 11th second.

In this embodiment of the present application, after playing the multimedia file according to the first playing rate, the user can also manually adjust the first playing rate, which improves the flexibility of the method for playing the multimedia file and improves the efficiency of adjusting the playing rate.

Optionally, when any account adjusts the playback rate of a multimedia file to the second playback rate, the second playback rate can be recorded by the terminal or the server, and when the account plays the same multimedia file again, it can directly follow the second playback rate. Play rate to play the multimedia file.

In the embodiment of the present application, the playback rate manually adjusted by the user can be recorded, and when the same multimedia file is played again, the multimedia file is directly played at the second playback rate, which improves the flexibility of the playback method of the multimedia file and improves the adjustment playback rate. rate efficiency.

The method provided by the embodiment of the present application can flexibly determine the first playback rate according to the historical playback rate of the multimedia file and the historical playback times corresponding to the historical playback rate. Therefore, the embodiments of the present application can reduce the complexity of manually adjusting the playing rate by the user, improve the flexibility of playing multimedia files, and improve the adjustment efficiency of the playing rate.
