Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a multimedia playing progress recording method according to an embodiment of the present invention, where the embodiment is applicable to recording a multimedia playing progress of a user in a process of playing multimedia on a terminal device, and the method can be executed by a multimedia playing progress recording device, which can be implemented by hardware and/or software and can be generally integrated in the terminal device, such as a personal computer, a smart phone, and the like.
The method specifically comprises the following steps:
the user plays multimedia on the terminal equipment, the multimedia can be video or audio, and online streaming media or multimedia stored locally in the terminal can be played through the terminal equipment. The playing operation of the multimedia played by the user in the terminal device may be an operation of the user clicking a playing button on a multimedia playing interface, for example, the user uses a mobile phone to play an online learning video, clicks the playing button on an interface of a video playing application program or receives a voice playing instruction input by the user, starts playing the video, records a position where the video starts playing, and if the video playing is not paused or interrupted and a progress bar is not fast forwarded or dragged, a playing segment that has already been played is located between the position where the video starts playing and the current playing position. If a pause or interruption occurs, for example, if the user clicks a pause button or exits the playing interface, the playing segment that has been played is located between the position where the playing is started and the position where the video is stopped, the playing segment can be continuously calculated if the video is continuously played from the pause or interruption, or another playing segment that has been played can be recorded at the pause or interruption as the new position where the playing is started. If the user fast forwards, fast backwards or drags the progress bar to adjust the playing position, the playing segment which is already played is between the position where the playing is started and the position where the video is played when the video is fast forwarded or dragged, for example, the video starts playing from the beginning, when the video is played to the 1 st minute, the user fast forwards for 10 seconds, then the playing segment which is already played is between the beginning of the video and the 1 st minute, and 1 minute and 10 seconds become the new position where the playing is started, and are used for calculating another playing segment. It should be noted that fast forward and fast backward in this embodiment refer to skipping forward or backward for a preset duration, or skipping forward or backward for a duration corresponding to a user operation, which is different from the double-speed playing, and the content in the skipped duration is not played, that is, the content acquired by the skipped duration is not played by the user. Therefore, it can be understood that the play segment in which the determined multimedia has been played may be one or more.
at least one play key point is preset in the multimedia, and the play key point can be a time node or a certain frame in the multimedia. The playing key points can be uniformly distributed, for example, one playing key point is set every 5 seconds, or the multimedia is equally divided, the playing key points are set at equally divided points, for example, the multimedia is equally divided by 4, and the playing key points are set at 1/4, 1/2, 3/4 and the end respectively. The playing key points can also be set according to the operation of a manager, for example, a learning course video, dense playing key points are set for video paragraphs of important knowledge points, and sparse playing key points are set for video paragraphs of non-important knowledge points. According to the starting position of the playing segment, it can be determined which playing key point or playing key points are included in the playing segment, and these playing key points included in the playing segment are already played, and these playing key points that have been already played are recorded for showing the progress of the multimedia playing.
And step 130, determining the playing progress of the multimedia according to the playing key points already played in the multimedia and all the playing key points.
After the played playing key points are recorded, all the playing key points in the multimedia are acquired, so that which parts of the multimedia are partially passed can be determined, and the playing progress of the multimedia is determined. The playing progress can be a ratio of the played playing segment to the total playing length of the multimedia.
According to the technical scheme of the embodiment, the played playing key point is determined through the played multimedia playing segment and the preset playing key point in the multimedia, the playing progress of the multimedia is further determined according to the played playing key point, the problem that the playing progress recording process is complex to process when the multimedia playing is stopped due to the fact that the multimedia playing duration is counted regularly is solved, and the effect of conveniently recording the progress of the multimedia playing of a user under the condition that the playing progress recording is accurate is achieved.
Example two
Fig. 2 is a flowchart of a multimedia playing progress recording method according to a second embodiment of the present invention, where the multimedia playing progress recording method according to the second embodiment of the present invention is further refined based on the above technical solution, and optionally, before determining and recording the playing key point that has been played according to the playing segment and at least one playing key point preset in multimedia, the method further includes: and setting at least one play key point in the multimedia according to the multimedia time length and the play key point setting condition. The multimedia playing progress recording method provided by the embodiment specifically comprises the following steps:
the playing key points may be uniformly distributed in the multimedia, and the playing key points need to be preset before the playing key points which have been played are determined by the playing key points and the playing segments. It can be understood that the step of setting the playing key point in the multimedia and the step 210 do not have a specific sequence, and the sequence of the step 210 and the step 220 shown in fig. 2 does not limit the sequence of the two steps. For multimedia with different durations, different playing key point setting modes can be provided. The playing key point setting condition may be that multimedia time length is used as a measurement condition, a plurality of different time length intervals are set, each time length interval corresponds to a respective playing key point setting mode, the playing key point setting mode may be that playing key points are sequentially set at fixed time length intervals, or multimedia is equally divided by equal division quantity, and playing key points are set at equal division points and at the end. More playing key points can be set for multimedia with longer duration, and the interval between adjacent playing key points can be larger when the multimedia duration is longer.
and 240, determining the playing progress of the multimedia according to the playing key points already played in the multimedia and all the playing key points. The multimedia playing progress is determined by the terminal equipment used by the user, and then the multimedia playing progress is reported to the server, the terminal equipment can report the multimedia playing progress to the server when the user leaves the multimedia playing interface, the multimedia playing is finished or the playing is interrupted, and can also report the multimedia playing progress according to a preset reporting time interval in the multimedia playing process. For the situation of reporting the playing progress of the multimedia in the multimedia playing process, the reporting time interval can be set according to the interval of the playing key points, and the larger the interval of the playing key points is, the larger the reporting time interval is.
Optionally, the setting at least one play key point in the multimedia according to the multimedia duration and the play key point setting condition includes:
comparing the multimedia time length with the boundaries of at least two preset time length intervals, and determining the preset time length interval to which the multimedia time length belongs;
and setting at least one playing key point in the multimedia according to a playing key point setting mode corresponding to the preset time interval to which the multimedia time belongs.
For multimedia with short duration, play key points can be set in the multimedia according to a preset number, and for multimedia with longer duration, play key points can be set in the multimedia according to a preset time interval.
Optionally, the setting, according to a playing key point setting manner corresponding to the preset duration interval to which the multimedia duration belongs, of at least one playing key point in the multimedia includes:
if the multimedia time length is less than or equal to a first preset time length, setting a playing key point at a multimedia preset playing position;
if the multimedia time length is longer than the first preset time length and is less than or equal to a second preset time length, setting one playing key point every other first preset interval time from the starting playing time of the multimedia;
if the multimedia time length is longer than the second preset time length and is less than or equal to a third preset time length, setting one play key point every second preset interval time from the starting play time of the multimedia;
if the multimedia time length is longer than the third preset time length, setting one play key point every third preset interval time from the starting play time of the multimedia;
the first preset time length, the second preset time length and the third preset time length are sequentially increased; the first preset interval, the second preset interval and the third preset interval are sequentially increased.
For example, 1, for multimedia with the multimedia duration less than or equal to 5 seconds, a playing key point is set, which may be set at a middle point of the multimedia. 2. For multimedia with the multimedia duration of 5 seconds less than or equal to 1 minute, setting a play key point every 5 seconds, recording the play progress every 5 seconds, and submitting the play progress every 5 seconds. 3. Setting a play key point according to 5 seconds for multimedia with the multimedia duration of 1 minute < the multimedia duration of 10 minutes, recording the play progress every 5 seconds, and submitting the play progress every 10 seconds. 4. Setting a playing key point according to 10 seconds for multimedia with the multimedia duration of 10 minutes < 30 minutes, recording the playing progress every 10 seconds, and submitting the playing progress every 20 seconds. 6. And (3) setting a playing key point according to 20 seconds for the multimedia with the multimedia duration being more than 30 minutes, recording the playing progress every 20 seconds, and submitting the playing progress every 40 seconds.
The playing key point setting scheme is theoretically more finely divided, and the recording progress is more accurate. But here a realistic constraint must be considered: the finer the segmentation of the video key points is, the more frequent the progress recording action is, which causes the pressure of front-end processing of the user to be high and the requirement on the processing capacity of a machine of the user to be high. In addition, the more frequently we submit schedules to the backend, the greater the backend request pressure and the higher the requirements on the backend server. So we must take a balance between accuracy of the cut and machine performance pressure, and the cut that is not ideal is too fine. The segmentation granularity needs to be adjusted according to actual conditions. The longer the video, the larger the granularity of segmentation, considering different video durations. Because of the large video, a certain key point is lost and is not recorded, and the whole influence is not large.
According to the technical scheme of the embodiment, the playing key points are set according to the multimedia duration, so that the pressure of related equipment is reduced under the condition that the playing progress record is accurate.
EXAMPLE III
Fig. 3 is a flowchart of a multimedia playing progress recording method according to a third embodiment of the present invention, where the multimedia playing progress recording method according to the present embodiment is further detailed based on the foregoing technical solution, and the multimedia playing progress recording method according to the present embodiment specifically includes:
the playing key points contained between the start and stop positions of the playing segments are determined as the playing key points covered by the playing segments, and the playing segments are considered to cover the playing key points under the condition that the playing key points are just at the start and stop positions of the playing segments.
and the elements contained in the progress record array correspond to the playing key points one by one and are initialized to preset initial values when the progress record array is generated. Setting a progress record array, wherein the number of elements in the progress record array is the same as the number of playing key points, all elements in the sequence from beginning to end correspond to the playing key points in the sequence from beginning to end one to one, and the numerical values of the elements in the progress record array can reflect whether the corresponding playing key points are played and how many times the playing key points are played. The elements in the progress record array are initially preset initial values, for example, the preset initial values are 0. When the playing key point is played, the element numerical value in the corresponding progress record array is modified, and the preset numerical value modification mode can add or subtract a fixed value to the current numerical value of the element. For example, if the initial value is set to 0, and a certain playing key point is played once, 1 is added to the corresponding element, and the corresponding element is played again, or 1 may be added.
The elements with the non-preset initial numerical values indicate that the corresponding playing key points are played, and then the elements with the non-preset initial numerical values and the total number of the elements can determine which playing key points have been played, and can determine the playing key points which have been played for several times, so as to determine the playing progress of the multimedia.
Optionally, the determining the playing progress of the multimedia according to the element, which is not the preset initial value, in the progress record array and the progress record array includes:
calculating the ratio of the number of elements which are not preset initial values to the total number of the elements to serve as the playing progress of the multimedia; or the like, or, alternatively,
and taking the variable quantity of the elements with the non-preset initial numerical values relative to the preset initial numerical values as the weight of the elements with the non-preset initial numerical values, and calculating the weighted ratio of the number of the elements with the non-preset initial numerical values and the total number of the elements to be used as the playing progress of the multimedia.
Illustratively, for one video, for example, 8 minutes of video.
1. According to the technical scheme, 96 playing key points are cut out by selecting one playing key point every 5 seconds, and then [0,0 \8230, 0] progress record arrays consisting of 96 0 are formed. These 96 play key points correspond to time axes of 5 seconds, 10 seconds, and 15 seconds. In addition, each number in the array, initially 0, indicates that the key point has not yet been recorded for play.
2. When a user opens a video playing page, the front-end page first obtains video information, which includes a progress record array corresponding to the video and playing key point segmentation granularity information of the progress record array, for example, a current video segments a playing key point in 5 seconds.
3. When a user starts playing a video, the front-end page monitors a playing progress event of the video (a player provides the event, which may be triggered 4 times per second, and different players are slightly different), if the current playing time reaches the playing key point of 5 seconds, the first zero in the progress record array is set to 1, if the playing time reaches the playing key list of 10 seconds, the second zero in the array is set to 1, and so on, if the user plays for 1 minute continuously, the progress record array changes to the arrays of the first 12 1, and the remaining arrays are 0: [1,1,1' \ 8230, 1,0,0,0 \8230and0,0 ]. For the array, the video playing progress can be calculated by simply dividing the number of the inner 1 by the total element number of the array, that is, 12/96=12.5%.
3. If the user pauses during the playing process, the video playing progress event does not exist, and the recording progress cannot be triggered naturally.
4. If the user drags the progress bar, the progress bar is not played in the dragging process, and a video playing progress event cannot be triggered. And after the drag and drop are finished, continuing to play, and recording the playing key points in the array because the middle video segment is not played. For example, a user normally plays for 1 minute first, then drags to a 3-minute position, and then continues to play for 1 minute, then the first 12 key points are triggered, 12 1 s are recorded, the next 12 key points are not played, the array is also recorded as 0, from the 25 th key point (125-second position) to the 36 th key time point (180 seconds), the array is recorded as 1, that is, the progress record array is: <xnotran> [1,1 … 1,1,0,0,0 … 0,0,1,1,1 … 1,1,0,0,0 … 0,0,0] 12 1, 12 0, 12 1, 0. </xnotran>
Thus, the calculation progress is as follows: 24/96=25%. It can be seen that dragging does not affect the recording progress, and completely conforms to the fact.
5. In addition, if the user repeatedly plays a certain section of the video, the progress recording array can also correctly record the progress. For example: if the user watches the first minute, drags the progress bar to the beginning, and watches the first minute once again, the front 12 key time points are all triggered twice, and the array records as [2,2 \8230; 2,0 \8230; 0], where there are 12 front 2, and the rest are all 0. From this array we clearly record that the user looked at 2 times the previous minute. At this time, the viewing progress is calculated, and if the duration of the repeated viewing is considered as not effective viewing, the number of the non-0 digits 12 is divided by the total number of the digits 96, that is, 12/96=12.5%. If we consider the length of the repeat viewing to also be in progress, 2+ \8230 ++ 2 (12/2)/96 =25% can be recorded.
6. The above progress recording is realized by updating the progress recording array mainly depending on the front-end page, and the array is also stored in the browser cache. The group is submitted to the back end of the server and stored, so that the video playing progress is not lost and is stored persistently. According to the performance of a back-end server, the simultaneous online playing amount of a platform user and the like, the frequency of submitting the back-end records is that the front-end records are submitted to the back-end records twice and once.
According to the technical scheme, the playing key points of playing are recorded by setting the progress recording array, so that the multimedia playing progress is calculated conveniently, the problem of inaccurate playing progress statistics when the progress bar is dragged is solved, the multimedia playing segments played repeatedly for many times can be reflected, and the condition that the user plays multimedia can be reflected more accurately.
