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. 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.

In some embodiments of the present invention, referring to fig. 1, a method for playing a media file cyclically is provided, including:

Step 101, when a circular playing instruction for an original media file is received, determining one or more target segments in the original media file according to preset characteristic information of the original media file; the preset feature information comprises historical playing record information, subtitle information or bullet screen information of the original media file.

Here, when receiving a circular playing instruction for an original media file, first, one or more target segments are determined in the original media file according to preset feature information (history playing record information, subtitle information, or bullet screen information) of the original media file, thereby realizing circular playing of partial segments of the original media file.

The original media file may be a video file or an audio file, etc.

and 102, circularly playing one or more target segments.

And the determined one or more target segments are played circularly, so that the circular playing of partial segments of the original media file is realized, the user requirements are met, and the user experience is improved.

for example, when A, B, C three target segments are determined in the original media file, A, B, C three target segments are played circularly, and A, B, C three target segments are played circularly in turn, for example, in the sequence of abcabcabc ….

the method for circularly playing the media file realizes the circular playing of partial segments of the original media file, meets the user requirements, improves the intelligence and the convenience, and improves the user experience.

As an optional implementation manner, the preset feature information includes history playing record information of the original media file; in step 101, the determining one or more target segments in the original media file according to the preset feature information of the original media file includes:

step 1011, according to the history playing record information, extracting one or more segments with continuous playing time exceeding a first preset threshold value from the original media file, and determining the extracted segments as the target segments; and the continuous playing time length is the time length of continuous playing in the original media file according to the original playing speed.

generally, when an original media file is played by a user, a progress bar is often dragged to a position where the user wants to see, and when the user does not want to continue to see after seeing a part of the original media file, the user can directly end the currently played media file, or drag the progress bar forward to watch the currently played media file again.

Here, one or more segments whose continuous playing time length exceeds a first preset threshold are automatically extracted from the original media file according to the history playing record information of the original media file, and at this time, the extracted segments are segments played by the user at the original playing speed during playing, but not fast-forwarded segments, that is, the extracted segments are segments that the user wants to watch. The extracted one or more segments are used as the segments of the circular playing, so that the watching requirements of the user are met, and the user experience is improved.

the first preset threshold value can be set according to requirements by combining the total duration of the original media file. For example, when the original media file is a video file within 10 minutes, the first preset threshold may be set to 3 minutes; the first preset threshold may be set to 10 minutes when the original media file is a video file within 1 hour.

Assuming that the original media file is a video file of 10 minutes, the first preset threshold is 3 minutes, and the continuously played segments recorded in the history play record are segments of "00: 00:00-00:00: 05" and "00: 01:00-00:05: 30", the segment of "00: 01:00-00:05: 30" is determined as the target segment by applying the method of the present invention.

At the moment, one or more segments which the user wants to watch are automatically extracted to be used as segments of the circular playing according to the historical playing record information of the original media file, so that the watching requirement of the user is met, and the watching experience is improved.

As another optional implementation manner, the preset feature information includes subtitle information of the original media file; in the above step 101, referring to fig. 2, the determining one or more target segments in the original media file according to the preset feature information of the original media file includes:

Step 1012, dividing the original media file according to the subtitle information of the original media file to obtain one or more scene segments including subtitles; the time interval between two adjacent subtitles of the same scene segment is smaller than a second preset threshold, and the time interval between any two subtitles of different scene segments is larger than or equal to the second preset threshold.

The original media files such as video files contain subtitles, and the original media files can be divided into different scenes, and the scenes containing the subtitles are watched by a user.

the method comprises the steps of firstly carrying out scene division on an original media file according to subtitle information to obtain one or more scene segments, wherein the scene segments are all segments including subtitles watched by a user, and determining the segments played circularly from the scene segments, so that the user requirements are met, and the user experience is improved.

The time interval between two adjacent subtitles of the same scene segment is smaller than a second preset threshold, and the time interval between any two subtitles of different scene segments is larger than or equal to the second preset threshold. At this time, because the time interval between the subtitles of the same scene is not too long, the time interval between two adjacent subtitles of the same scene segment is limited within the second preset threshold value, and the accuracy of scene segment division is ensured.

the second preset threshold may be set according to a requirement, for example, may be set to 6 seconds.

And 1013, when the duration of the scene segment is greater than a third preset threshold, determining the scene segment as the target segment.

And when the duration of the scene segment is greater than a third preset threshold, the scene segment is determined as a target segment, and the scene segment with too short duration is not circulated, so that the requirements of users are further met, and the user experience is improved.

The third preset threshold may also be set according to requirements, for example, may be set to 10 seconds.

Further, the step 1012 may include:

Step 10121, obtaining the start time and the end time of the segment corresponding to each subtitle in the original media file.

here, the start time and the end time of the segment corresponding to each subtitle in the original media file are first obtained, and support is provided for subsequently dividing the scene segments based on the time interval of the subtitles.

Step 10122, obtaining the time interval between the end time of the first caption and the start time of the second caption; and the second subtitle is a subtitle appearing for the first time after the first subtitle.

here, the time interval between the ending time of the first subtitle and the starting time of the second subtitle is obtained, and support is also provided for the subsequent scene segment division based on the time interval of the subtitles.

the first subtitle refers to any one subtitle in the original media file and has no special meaning.

Step 10123, if the time interval is smaller than the second preset threshold, dividing the segment corresponding to the first subtitle and the segment corresponding to the second subtitle into the same scene segment.

step 10124, if the second time interval is greater than or equal to the second preset threshold, dividing the segment corresponding to the first subtitle and the segment corresponding to the second subtitle into two different scene segments.

here, if the time interval between the first subtitle and the second subtitle is less than a second preset threshold (e.g., 6 seconds), the segments corresponding to the two subtitles are divided into the same scene segment, otherwise, the segments corresponding to the two subtitles are divided into different scene segments, so that the time interval between two adjacent subtitles of the same scene segment is limited within the second preset threshold.

at this time, scene division is automatically carried out on the original media file based on the time interval between the subtitles, one or more scene segments comprising the subtitles are obtained, and the segments played circularly are determined from the scene segments, so that the user requirements are met, and the user experience is improved.

An example of an application of the above method according to an embodiment of the present invention is illustrated as follows.

Assume that the second preset threshold is 6 seconds and the third preset threshold is 10 seconds. Firstly, the start time and the end time of a segment corresponding to each subtitle in an original media file are obtained, as shown in the following table 1:

number L	Caption	Starting time	End time
				1	aaa	00:01:15:760	00:01:17:320
2	bbb	00:01:20:360	00:01:22:120
				3	ccc	00:01:23:560	00:01:25:080
4	ddd	00:01:30:480	00:01:34:080
				5	eee	00:02:17:480	00:02:18:800
6	fff	00:02:21:160	00:02:23:920
				7	ddd	00:02:36:320	00:02:49:240

TABLE 1

then, the time interval between two adjacent subtitles is obtained through table 1 above, and it can be obtained that:

the time interval N1 between L1 and L2 is 03: 020;

The time interval N2 between L2 and L3 was 01: 440;

The time interval N3 between L3 and L4 was 05: 400;

The time interval N4 between L4 and L5 was 43: 300;

The time interval N5 between L5 and L6 was 02: 360;

The time interval N6 between L6 and L7 was 12: 400.

and if the N1, the N2 and the N3 are all less than 6 seconds, dividing the L1-L4 into the same scene segment A of '00: 01:15:760-00:01:34: 080'. If N4 is greater than 6 seconds and N5 is less than 6 seconds, L4 and L5 are divided into different scene segments, and L5 and L6 are divided into the same scene segment, i.e., L5 and L6 are divided into another scene segment B "00: 02:17:480-00:02:23: 920". N6 is greater than 6 seconds, L6, L7 are divided into different scene segments, i.e., L7 alone as another scene segment C "00: 02:36:320-00:02:49: 240".

The duration of the scene segment B is less than 10 seconds, and the durations of the scene segments a and C are greater than 10 seconds, so that the scene segments a and C are determined as target segments.

As another optional implementation manner, the preset feature information includes bullet screen information of the original media file; in the above step 101, referring to fig. 3, the determining one or more target segments in the original media file according to the preset feature information of the original media file includes:

1014, acquiring one or more bullet screen dense points in the original media file according to the bullet screen information of the original media file; and the bullet screen dense points are peak points in a curve of the bullet screen quantity changing along with time.

Currently, the barrage function is already common in the playing process of media files, and the user group is huge. Usually, the media file is a region with a dense bullet screen around the time point which is very wonderful and is most desired to be watched by the user.

here, first, according to the bullet screen information of the original media file, one or more bullet screen dense points are obtained from the original media file, the bullet screen dense points represent time points which a user most wants to watch, and the segment of the circular playing is determined based on the time points, so that the user demand is met, and the user experience is improved.

the curve of the bullet screen quantity changing along with time visually displays the trend of the bullet screen quantity changing, and bullet screen dense points can be accurately acquired based on the curve. The vicinity of the peak point in the curve of the bullet screen quantity changing along with the time is the bullet screen dense area, so that the peak point in the curve of the bullet screen quantity changing along with the time can be extracted as a bullet screen dense point.

Specifically, the time of occurrence of each bullet screen in the bullet screen information of the original media file may be read first. Taking the b-station bullet screen file as an example, for example, the format of each bullet screen in the b-station bullet screen file is as follows:

< d p ═ 36.870998368,1,25,16777215,1312863760,0, eff85771,42759017"> head-line position.

The first parameter is the time of the bullet screen, in seconds. The "front occupation position" is the bullet screen content.

and then, counting the number of the bullet screens in unit time according to the occurrence time of each bullet screen, and obtaining a curve of the number of the bullet screens changing along with the time. The unit time can be set according to the requirement, such as 1 second, 5 seconds, 10 seconds, and the like. And finally, extracting a peak point from a curve of the bullet screen quantity changing along with time to serve as a bullet screen dense point.

for example, a curve of the number of bullet screens changing with time is shown in fig. 4, and if three peak points d, e, and f are included in the curve, the three peak points are taken as bullet screen dense points.

Step 1015, determining the segments of the original media file with the preset duration including the bullet screen dense points as the target segments.

Here, the fragments of the original media file including the bullet screen dense points within the preset time duration, namely the bullet screen dense areas near the bullet screen dense points, are determined as the target fragments, so that the user requirements are met, and the user experience is improved.

Specifically, the bullet screen dense point can be used as a central point, and a certain time is respectively prolonged to the front and the back of the bullet screen dense point, so that fragments with preset duration including the bullet screen dense point are obtained.

For example, as shown in fig. 4, three bullet screen dense points d, e, and f are respectively used as center points, and the distance is extended by 120 seconds from front to back, so that D, E, F three segments are obtained as target segments.

at the moment, based on the bullet screen information, the bullet screen dense area near the bullet screen dense point is automatically determined as a segment of the circular playing, so that the user requirement is met, and the user experience is improved.

Optionally, the number of bullet screens corresponding to the bullet screen dense point is greater than a fourth preset threshold.

Here, the bullet screen dense point is a peak point in a curve of the bullet screen quantity changing along with time, and the bullet screen quantity corresponding to the bullet screen dense point is greater than a fourth preset threshold value. The fourth preset threshold value can be set according to requirements.

At this moment, the fragments near the peak point with the bullet screen quantity larger than the fourth preset threshold value are circulated, and the fragments near the peak point with the small bullet screen quantity, namely the fragments which are not very interesting to the user, are not circulated, so that the user demand is further ensured, and the user experience is improved.

To sum up, the method for cyclically playing the media file according to the embodiment of the present invention can automatically determine one or more segments to cyclically play according to the history playing record information, the subtitle information, or the barrage information of the original media file, so as to implement cyclic playing of a part of segments of the original media file, meet the user requirements, improve the intelligence and the convenience, and improve the user experience.
