Fig. 1 is a flowchart of a method for determining a video play multiplier provided by an embodiment of the present disclosure, where the method may be performed by a device for determining a video play multiplier, where the device may be implemented by software and/or hardware, and may generally be integrated in an electronic device, for example, a device having video processing capabilities, such as a server. As shown in fig. 1, the method mainly includes the following steps S102 to S106:
step S102, a plurality of current segments corresponding to the target video and a current playing speed value corresponding to each current segment are obtained.
The embodiment of the disclosure does not limit the video type and the video content of the target video, and any video can be used as the target video. In the embodiment of the disclosure, the fact that the user is required to determine the video playing double speed value completely in the related art is fully considered, the playing double speed value of the video is complicated in the video playing period by manually adjusting the video playing double speed value by the user, and the user may need to adjust the video playing double speed value repeatedly for multiple times, for example, the user considers that the playing speed of the current video segment is too slow to adjust the video playing double speed to be 2 times, but finds that the 2 times speed is too fast, then adjusts the video playing double speed to be 1.5 times, and the user finds that the next video content is important after playing a section of video according to 1.5 times speed, key information is easy to lose according to 1.5 times speed playing, and the user also needs to reduce the playing double speed value repeatedly, so that the video viewing experience of the user is poor. For this reason, the embodiment of the present disclosure may segment the target video into a plurality of segments in advance, and set a play multiplier value corresponding to each segment. And the follow-up process can be further carried out on the segments of the target video and the corresponding playing speed values until the segments meeting the requirements of the public and the corresponding playing speed values are obtained.
It should be noted that, in the embodiment of the present disclosure, the obtained multiple current segments corresponding to the target video and the current play multiplier value corresponding to each current segment may be an original segment that is not optimized initially and a play multiplier value that is set originally, or may be a segment that has been optimized and adjusted based on the original segment and a play multiplier value that is optimized and adjusted, which is not limited herein. Specifically, the implementation can be realized with reference to the following two implementation examples:
in some embodiments, the plurality of current segments are obtained by slicing the target video according to a preset node, and the current playing speed multiplier is a preset value. One or more nodes may be included in the target video, and the node presetting mode of the target video is not limited in the embodiment of the present disclosure, for example, the target video may be divided into a plurality of nodes in advance according to the video content of the target video, and the target video is, for example, a classroom teaching video, and may be divided into a plurality of segments, which are respectively a segment corresponding to "knowledge point introduction", a segment corresponding to "knowledge point explanation", a segment corresponding to "discussion and divergence", a segment corresponding to "knowledge point exercise", and a segment corresponding to the remaining content. It will be appreciated that different segments in the same video, due to different content, adapt at different speeds. Taking the segment corresponding to the 'knowledge point introduction' as an example, knowledge points are introduced in a mode such as animation or real cases, so that students are interested in a certain knowledge point, if the segment is played at multiple speeds, such as 2 times of speed, the influence is not great, the students can not miss important information, the students can save time, and the learning efficiency is improved. Taking the section corresponding to "knowledge point explanation" as an example, most of the sections are important contents such as formal knowledge point analysis, solution, thinking and the like, and the user needs to understand more thinking, so that the section is not suitable for multi-speed playing, and the normal multi-speed can be set. The foregoing is merely illustrative, and in practical application, the corresponding node and play speed value may be set according to whether the content included in the video is urgent or not or according to a plurality of links of the content included in the video, which is not limited herein. The original segment segmentation and play speed doubling values can be initialized and set by a producer or a processor of the target video according to experience, so that cold start is realized; the segmentation mode and the play speed value of the segment can be further optimized and adjusted according to the actual performance of the user watching the target video.
In other embodiments, the plurality of current segments are obtained by performing subdivision processing on a plurality of preset original segments of the target video, and the current playing speed value is obtained by adjusting based on the preset original playing speed value corresponding to the original segments. That is, the current segment may have been further optimized based on the original segment that was initially segmented, such as by further segmenting the original segment one or more times, and iteratively optimizing the original segment in a subdivision manner to obtain a plurality of current segments. Similarly, the current playing speed doubling value may also be a playing speed doubling value corresponding to each current segment obtained by directly optimizing on the basis of the preset original playing speed doubling value, and the specific optimization mode is not limited herein.
Step S104, obtaining a double-speed operation record of a historical watching user of the target video aiming at the target video; the target video is played according to the sequence of the current clips and the current playing speed value corresponding to each current clip and is presented to the historical viewing user. Specifically, based on time information of each current segment in the target video, the sequence of the current segments can be determined, in the embodiment of the present disclosure, intelligent double-speed playing of the target video can be directly realized according to the sequence of the current segments and the current playing double-speed value corresponding to each current segment, and the double-speed operation record of the watching user (history watching user) in the process can be obtained, so that the current segment and the current playing double-speed value are further optimized and adjusted based on the double-speed operation record.
In some embodiments, the double-speed operation record includes a double-speed adjustment node corresponding to a double-speed adjustment operation performed by a history viewing user on the target video; the double-adjustment node can be understood as a time point when the historical viewing user executes double-adjustment operation in the playing process of the target video; the double speed operation record may further include a double speed adjustment value corresponding to the double speed adjustment node, for example, 0.75 double speed, 1 double speed, 1.25 double speed, 1.5 double speed, 2 double speed, and the like, and is not limited thereto. It can be understood that the double-speed adjustment operation is used for indicating that video playing is performed after the double-speed adjustment node according to the double-speed adjustment value set by the user.
And S106, carrying out subdivision processing on the plurality of current fragments according to the double-speed operation record to obtain a plurality of target fragments, and determining a target playing double-speed value corresponding to each target fragment according to the double-speed operation record and the current playing double-speed value.
It can be understood that, in general, the target video may have a plurality of historical viewing users, and multiple speed operation records of each historical viewing user may be counted, and a plurality of current segments are subdivided according to the multiple speed operation records of each historical viewing user, so as to optimize the current segments and obtain a plurality of target segments. Specifically, the plurality of current segments may include segments subjected to subdivision processing and segments not subjected to subdivision processing at the same time, and for convenience of understanding, the following is exemplified:
For segment A, if most users perform double adjustment during the playing of segment A, segment A is described
The current double-speed play value of the video game is unreasonable, so that the time point of the double-speed operation performed by the user in the segment A can be counted based on the double-speed operation record, the double-speed adjustment node is determined based on the counted time point, the segment A is further subdivided based on the double-speed adjustment node, and the segment A can be regarded as being subdivided into two target segments. For the segment B, if the most users do not perform the double adjustment operation during the playing of the segment B, it is indicated that the most users are satisfied with the playing double speed value of the segment B, the segment B is still completely reserved without adjusting the segment B, and the segment B is used as a target segment as a whole. It should be noted that the above is merely an example, and in practical application, the manner of determining whether the current segment needs to be subdivided according to the speed-doubling operation record is not limited, and not every current segment needs to be subdivided. By the method, the segments of the current segments after the subdivision processing are the target segments corresponding to the target video.
The target segments and the corresponding target playing double-speed values are determined based on double-speed operation records of historical watching users, so that the method is more reasonable, meets the requirements of masses, is beneficial to achieving the effect of better video segment double-speed playing, and can play target videos according to the sequence of a plurality of target segments and the target playing double-speed value corresponding to each target segment under the condition that an intelligent double-speed playing request is received, thereby achieving intelligent double-speed playing meeting the requirements of users, avoiding manual adjustment of the users, and improving the video watching experience of the users. In addition, it should be noted that the following steps may further adjust the target segment and the target play multiplier, and at this time, the target segment and the target play multiplier may be used as the current segment and the current play multiplier in step S102 and execute the following operations again, so that the following steps may be repeated for multiple iterations, and the adjustment is continuously performed. For example, a period duration, such as one day, one week, or one month, may be set, and each time a period duration is reached, an optimization adjustment may be performed, which may be flexibly set according to the needs, and is not limited herein.
On the basis that the double-speed operation record includes a double-speed adjustment node corresponding to the double-speed adjustment operation performed by the history viewing user on the target video, the step S106 of performing subdivision processing on the plurality of current segments according to the double-speed operation record to obtain a plurality of target segments may be exemplarily performed with reference to the following steps (1) to (2):
And (1) determining a target adjustment node according to the multiple adjustment nodes corresponding to the plurality of historical viewing users. It can be appreciated that the multiple adjustment nodes corresponding to the multiple adjustment operations performed by different historical viewing users may be the same or different, so that statistics may be performed on multiple adjustment nodes of the historical viewing users to determine a target adjustment node that meets most of the user needs.
For each current segment, counting multiple adjustment nodes corresponding to a plurality of historical viewing users in the current segment, and obtaining a node counting result corresponding to the current segment; and under the condition that the node statistical result corresponding to the current segment meets the preset condition, determining a target adjustment node corresponding to the current segment based on the node statistical result corresponding to the current segment. The node statistics manner is not limited in the embodiment of the present disclosure, for example, the distribution condition of multiple adjustment nodes corresponding to multiple historical viewing users in the current segment may be counted, so as to determine the occurrence frequency of each multiple adjustment node, further find out the multiple adjustment node with the largest occurrence frequency, and also understand that the maximum distribution point is found. For example, a total of 10 users perform a double speed adjustment operation for segment a, 2 users perform double speed adjustment at time point 1 in segment a, 7 users perform double speed adjustment at time point 2 in segment a, 1 user performs double speed adjustment at time point 3 in segment a, and the node statistics result includes: time point 1 is taken as a double adjustment node 1, and the occurrence frequency is 20%; time point 2 is taken as a double adjustment node 2, and the occurrence frequency is 70%; time point 3 was set as double adjustment node 3, and the frequency of occurrence was 10%. The higher the frequency of occurrence of the double adjustment node, the more users choose to perform the double adjustment operation on the node. In order to ensure the reliability of the target adjustment node and ensure that the target adjustment node can meet the needs of most users, the embodiment of the disclosure limits the node statistics result, and only if the node statistics result meets the condition, the target adjustment node corresponding to the current segment is determined; if the node statistics result corresponding to the current segment does not meet the preset condition, the target adjustment node corresponding to the current segment is not determined, that is, the subdivision and optimization processing is not performed on the current segment, and the current segment and the playing speed value corresponding to the current segment are still completely reserved.
In some specific implementation examples, the preset conditions include: the highest occurrence frequency corresponding to the double adjustment node in the current segment is not smaller than a preset threshold value; on the basis, the step of determining the target adjustment node corresponding to the current segment based on the node statistical result corresponding to the current segment comprises the following steps: and taking the double-speed adjustment node with the highest occurrence frequency indicated by the node statistics result corresponding to the current segment as the target adjustment node corresponding to the current segment. That is, the embodiment of the present disclosure ensures that the target adjustment node is indeed a node that meets the needs of the public by setting a threshold, such as, assuming that the threshold is 65%, the highest occurrence frequency corresponding to the double adjustment node of the segment a in the above example is 70%, the preset condition is met, so the double adjustment node 2 may be taken as the target adjustment node; and assuming that the threshold value is 80%, the highest occurrence frequency 70% corresponding to the double adjustment node of the segment a in the above example does not meet the preset condition, so it is determined that the target adjustment node does not exist in the current segment. The foregoing is merely an example, and the preset threshold may be flexibly set in practical application, and the preset condition that needs to be met by the node statistics result is flexibly set, which is not limited herein. That is, only when most users commonly execute the double adjustment operation on a certain node in the current segment, the current segment is cut and optimized, and if the nodes of the users executing the double adjustment operation on the current segment are scattered, the occurrence frequency of each node is not high, the representativeness is not strong, the target adjustment node and further adjustment are not additionally determined, so that the public demand cannot be met. Through the mode, the reliability of the target adjusting node can be effectively guaranteed, and the target adjusting node is ensured to be an adjusting node meeting the requirements of the public.
Step (2), executing segmentation operation on the current segment where the target adjustment node is located, and obtaining a plurality of target segments based on segmentation results; the target adjustment node is a segmentation point corresponding to the segmentation operation. I.e. the current segment where it is located is split at the target adjustment node.
Specifically, a segmentation operation is respectively executed for the current segment of each target adjustment node, and the current segment of each target adjustment node is segmented into a front segment and a rear segment; each small segment is regarded as a target segment; it can be understood that a segment with a target adjustment node may exist in the plurality of current segments, a segment without a target adjustment node may also exist, and the segmentation operation is not performed on the segment without the target adjustment node, and the segment is regarded as a target segment as a whole; in this way, a plurality of target fragments can be obtained.
On the basis that the double-speed operation record further includes a double-speed adjustment value corresponding to the double-speed adjustment node, the step of determining, in step S106, the target play double-speed value corresponding to each target segment according to the double-speed operation record and the current play double-speed value may be performed, for example, by referring to the following manner: regarding a current segment which has executed the segmentation operation, taking a current playing double-speed value corresponding to the current segment as a target double-speed adjustment value of a first target segment in the current segment, and determining a target double-speed adjustment value of a second target segment in the current segment based on the double-speed adjustment value corresponding to a double-speed adjustment node in the current segment; the first target segment in the current segment is a sub-segment located before the target adjustment node in the current segment, and the second target segment in the current segment is a sub-segment located after the target adjustment node in the current segment. That is, the segment before the segmentation still maintains the original double speed adjustment value, but the double speed adjustment value of the segment after the segmentation is changed, and the changing mode of the double speed adjustment value of the segment after the segmentation mainly depends on the double speed operation record of the historical viewing user.
In practical application, the step of determining the target double speed adjustment value of the second target segment in the current segment based on the double speed adjustment value corresponding to the double speed adjustment node in the current segment may first obtain an average value of the double speed adjustment values corresponding to the double speed adjustment nodes in the current segment when the method is specifically implemented; the average value is then taken as the target multiple adjustment value for the second target segment in the current segment. By means of averaging, the target multiple adjustment value can be enabled to meet the public demands as much as possible.
For the understanding of the foregoing manner provided by the embodiments of the present disclosure, referring to a double adjustment schematic diagram shown in fig. 2, it is simply shown that a target video has 3 current segments, namely current segment 1: a1 to a2, current fragment 2: a2 to a3, current fragment 3: a3 to a4. The current playing speed value of the current segment 1 is s1, the current playing speed value of the current segment 2 is s2, and the current playing speed value of the current segment 3 is s3. By determining that the target adjustment node of the current segment 1 is b1 and the target adjustment node of the current segment 2 does not exist, and the target adjustment node of the current segment 3 is b2 in the above manner, the current segment 1 and the current segment 3 are segmented based on b1 and b2, and the current segment 2 remains unchanged, so that the last 5 target segments are respectively: target fragment 1: a1 to b1, target fragment 2: b1 to a2, target fragment 3: a2 to a3, target fragment 4: a3 to b2, target fragment 5: b2 to a4. The target playing speed value of the target segment 1 is still s1, the target playing speed value of the target segment 2 is adjusted to s1', the target playing speed value of the target segment 3 is still s2, the target playing speed value of the target segment 4 is still s3, and the target playing speed value of the target segment 5 is adjusted to s3'. The above is only one round of adjustment example, in practical application, the double-speed operation records of the watching user during the playing period according to the five target segments can be continuously collected, and the five target segments are further optimized and adjusted as the current segments, which is not described herein. Through the method, the video segmentation mode and the corresponding playing double-speed value can be optimized once or multiple times, so that the double-speed playing mode meeting the requirements of most users is found.
On the basis of the foregoing, an embodiment of the present disclosure provides a video playing method, and fig. 3 is a schematic flow chart of the video playing method provided in the embodiment of the present disclosure, where the method may be performed by a video playing apparatus, where the apparatus may be implemented by using software and/or hardware, and may generally be integrated in an electronic device, where the electronic device may be a device with video processing capability, such as a server. As shown in fig. 3, the method mainly includes the following steps S302 to S304:
step S302, a plurality of target fragments corresponding to target videos and target playing double-speed values corresponding to each target fragment are obtained in response to receiving an intelligent double-speed playing request; the target fragment and the target playing speed value are obtained by the method for determining the video playing speed value; reference is made to the foregoing, and details are not repeated here.
In some embodiments, a functional control for a user to initiate an intelligent double-speed playing request is provided on the video playing interface, and the user can initiate the intelligent double-speed playing request by triggering a functional control point mode to indicate that the user starts an intelligent double-speed playing function, and then play according to a plurality of target segments corresponding to the target video and the target playing double-speed value corresponding to each target segment. Further, in order to make the user clearly understand the function of the intelligent double-speed playing function, a prompt message can be initiated in response to detecting the triggering operation of the function control; the prompt message is used for indicating the corresponding estimated total duration and/or the estimated saving duration of the target video under the condition of intelligent double-speed playing. Through the method, the user can clearly know the time length saved by playing the video intelligently at double speed, and can directly select the function when the user needs to watch the video with high efficiency, so that the user experience is effectively improved.
Step S304, playing the target video according to the sequence of the target fragments and the target playing speed value corresponding to each target fragment. Specifically, determining the sequence of a plurality of target fragments according to the time period of each target fragment corresponding to the target video, and then playing each target fragment according to the target playing speed value corresponding to the target fragment until the video is finished or until the user intervenes.
Through the mode, the intelligent double-speed playing function meeting the requirements of the public can be automatically provided for the user without manual adjustment of the user, so that the user can efficiently acquire the video content information without losing key information, the user does not need to manually execute double-speed adjustment operation, and the video watching experience of the user is better improved.
In addition, the embodiment of the disclosure can also be used for manually adjusting the speed according to the requirement, and in case the user hopes to change the current speed value according to the requirement during intelligent speed-doubling playing, the speed-doubling can also be manually adjusted at any time, so that the watching experience of the user is fully ensured, and the watching requirement of the user is met. Based on this, the above method further includes the following steps 1 to 2a or 2b to be performed:
Step 1, responding to a received double adjustment request, and acquiring a double adjustment node and a double adjustment value corresponding to the double adjustment request. In practical applications, a user may initiate a double adjustment request at any time during smart double-speed playing to perform double adjustment operation, such as setting a time node and a corresponding double adjustment value for double adjustment required for a target video.
And 2a, executing speed limiting operation under the condition that the speed doubling adjustment value corresponding to the speed doubling adjustment request is higher than the speed doubling threshold value, and playing fragments positioned behind the speed doubling adjustment node corresponding to the speed doubling adjustment request in the target video based on the speed doubling adjustment value after the speed limiting operation.
In order to ensure the absorption effect of the video information of the user, and avoid that the user loses important information in the video playing process due to the selection of the excessively high speed, the embodiment of the present disclosure sets a speed-doubling threshold, and if the user hopes that the speed-doubling adjustment value is higher than the preset speed-doubling threshold, the speed-limiting operation can be performed, and the embodiment of the present disclosure does not limit the speed-limiting operation manner, and the speed-limiting operation includes: and initiating a message for prompting poor watching effect, or modifying the double speed adjustment value corresponding to the double speed adjustment request so that the modified double speed adjustment value is equal to the double speed threshold. Through the speed limiting operation, the user can be ensured to efficiently acquire the video content information without losing important information, such as the video content information can be well applied to teaching videos, so that the learning effect of students is fully ensured. For the speed limiting operation, only a prompt message is initiated, if the user still adheres, the speed doubling adjustment value after the speed limiting operation is still the speed doubling adjustment value corresponding to the speed doubling adjustment request, that is, the speed doubling adjustment value is played according to the speed doubling adjustment value set by the user, and for the speed limiting operation, when the speed doubling adjustment value is modified to be equal to the speed doubling threshold value, the speed doubling adjustment value after the speed limiting operation is the speed doubling threshold value, that is, the speed doubling adjustment value is played according to the maximum speed doubling threshold value.
The disclosed embodiments do not limit the speed multiplier threshold, which in some implementations is a preset value. In other embodiments, the double speed threshold is a target play double speed value corresponding to a target segment where a double speed adjustment node corresponding to the double speed adjustment request is located. That is, considering that the target playing speed is a speed that meets the needs of the public users, in order to ensure the information absorbing effect of the users, it is not recommended that the playing speed set by the users is higher than the target playing speed obtained by statistics. In addition, the target play multiplier may be further limited to ensure that the target play multiplier, which is the multiplier threshold, is set based on the needs of most people, such as setting the target play multiplier to the multiplier threshold assuming that more than 80% of users initially adjust for the target segment. Through the mode, the video watching effect of the user can be effectively guaranteed, and the phenomenon that key information is lost due to the fact that the user blindly sets high-speed can be avoided.
And step 2b, playing the segment positioned behind the double-speed adjustment node corresponding to the double-speed adjustment request in the target video based on the double-speed adjustment value corresponding to the double-speed adjustment request under the condition that the double-speed adjustment value corresponding to the double-speed adjustment request is not higher than the double-speed threshold. That is, under the condition that the play speed value set by the user is reasonable, the play can be directly performed according to the play speed value set by the user, and the key information can be ensured not to be lost by the user on the basis of meeting the user demand. In addition, it can be understood that after the user initiates the double-speed adjustment request, the user can be regarded as terminating the intelligent double-speed playing, and after the double-speed adjustment node corresponding to the double-speed adjustment request initiated by the user, the video playing is uniformly performed according to the playing double-speed value set by the user.
In summary, according to the method provided by the embodiment of the disclosure, the target video can be initially segmented according to the preset node in advance, and the initial playing double-speed value is preset, so that cold start is realized, the video segments can be segmented for multiple times and the corresponding playing double-speed value can be determined further based on the double-speed adjustment operation of the user, the user can continuously obtain better video playing experience by the iterative optimization mode, the intelligent double-speed playing effect meeting the requirements of the public user can be achieved without manually adjusting the double-speed value by the user, the content information of the video can be efficiently obtained by the intelligent double-speed video playing mode, important information cannot be missed, and the user experience is effectively improved.
