Fig. 1 is a flowchart of a video processing method according to an embodiment of the present application, where the method includes the following steps S11-S13:
in step S11, in the case of receiving a preset trigger event, intercepting a sub-video whose audio information meets a preset condition from the video data;
in step S12, a target video segment in which the difference between adjacent video frames in the sub-video is smaller than a first preset threshold is obtained;
in step S13, the playback speed adapted to the target video segment is processed.
The execution subject of the present application may be a server providing an online on-demand service and/or a video download service, and such a server may process videos in the server in advance through the above-mentioned steps S11-S13.
The execution subject of the application can also be a computer or a terminal device for playing streaming media video or local video. For example, when a computer or a mobile terminal requests a video online, if the server does not adapt the playing double speed for the video segment suitable for double speed playing in the video, since the current streaming media data is pre-buffered during playing, that is, a video segment of tens of seconds to several minutes is pre-buffered to avoid pause during playing the streaming media video, the mobile terminal may process the video segment appearing in the buffer through the above steps S11-S13. For another example, when the computer or the mobile terminal detects that a complete video is locally stored, the locally stored complete video may also be processed through the above steps S11-S13.
In the embodiment, a sub-video with audio information meeting preset conditions is intercepted from video data under the condition of receiving a preset trigger event; specifically, the preset trigger event includes: receiving an event of a complete video to be processed; or detecting an event that a video clip to be processed appears in the cache, wherein the sub-video with the audio information meeting the preset condition is the sub-video with the audio volume smaller than a preset value. Acquiring a target video section of which the difference of adjacent video frames in the sub-video is smaller than a first preset threshold;
and the difference of the adjacent videos in the sub-video can be determined by the following method:
in a first mode
Converting adjacent video frames into corresponding gray-scale images;
acquiring a histogram corresponding to the gray-scale image to count the probability of each gray-scale value in the gray-scale image;
the comparison of the histograms determines the difference of adjacent video frames.
Mode two
Acquiring adjacent video frames in the sub-video;
comparing pixel values of the same position of adjacent video frames;
counting the number of the same pixel values of the same position of the adjacent video frames;
and determining the difference of the adjacent video frames in the sub-video according to the number of the same pixel values of the same positions of the adjacent video frames.
The difference between adjacent video frames is small, which indicates that the picture change amplitude is not large, and thus the plot advancing speed in the video is slow. Therefore, the target video segment with small adjacent frame difference is suitable for fast playing, and therefore, the corresponding playing double speed is adapted to the target video segment.
And processing the playing speed adapted to the target video paragraph, for example, when the video is played to the target video paragraph, playing the video at the adapted playing speed, or giving a prompt to the user to prompt the user that the video is suitable for playing at the multiple speed.
Taking a teaching video as an example, in the teaching video, when a teacher plays a blackboard writing on a blackboard, the main content of the video is the blackboard writing operation of the teacher, and the teacher may not speak in the period of time; or the teacher presents a problem that people firstly have a few minutes of thinking time and then continue teaching, and in the period of time, the video picture possibly does not change and no sound exists. Such a scenario allows the student to play quickly without missing important information.
In view of such circumstances, in the present application, when the video is processed, a sub-video with no audio information or low audio information volume is captured from the video, where no audio information indicates that the teacher does not speak, and low audio information volume may be a noise generated when the teacher performs writing or walks. Further analyzing the intercepted sub-video, and acquiring a target video section with the difference of adjacent video frames smaller than a first preset threshold value from the sub-video; for example, in a video paragraph of a blackboard-writing performed by a teacher, the change range of the posture and the position of the teacher is small, if the video paragraph is played at twice speed, important information cannot be missed, but the blackboard-writing process is smoother, so that the video paragraph can be adapted to the twice playing speed. For video paragraphs with almost unchanged pictures, for example, video paragraphs for which the teacher has left students to think about the problem time, the posture and position of the teacher hardly change, and the video paragraphs are played at triple or quadruple speed, so that the time of video viewers can be greatly saved. The beneficial effect of this application lies in: the method comprises the steps that a sub-video with audio information meeting preset conditions can be intercepted from video data, and then a target video section with the difference of adjacent video frames in the sub-video smaller than a first preset threshold value is obtained; the playing speed multiplication matched with the target video paragraph is processed, and then the part suitable for speed multiplication playing can be played quickly through automatic speed multiplication playing or prompting the user, so that the time of the user is saved, and the user experience is improved.
In one embodiment, the preset triggering event includes:
receiving an event of a complete video to be processed; or
An event is detected in which a pending video segment is present in the buffer.
In this embodiment, the preset trigger event may be an event of receiving a complete video to be processed; for example, the server receives an event of a complete video uploaded by the user, and for example, the terminal or computer device detects the time to download a complete video locally from a website or application.
In addition, the preset trigger event can also be an event that a video clip to be processed is detected to appear in the cache; for example, when a terminal or a computer device requests a streaming media video through a server providing a video-on-demand service, since current streaming media data is pre-buffered during playing, that is, when the streaming media video is played, a video clip of ten seconds to several minutes is pre-buffered into a local buffer to avoid blocking, the preset trigger time may also be an event that a to-be-processed video clip occurs in the buffer. Therefore, the method and the device can also be applied to processing the streaming media video clip in the video on demand process.
In one embodiment, the above step S11 can be implemented as the following steps A1-A2:
in step a1, intercepting audio information of which the volume is smaller than a second preset threshold value from the audio information;
in step a2, the video segment corresponding to the audio information with the volume less than the second preset threshold is determined as the sub-video meeting the preset condition.
In the teaching video, when a teacher plays a blackboard writing on a blackboard, the main content of the video is the blackboard writing operation of the teacher, and the teacher may not speak in the period of time; or the teacher presents a problem that people firstly have a few minutes of thinking time and then continue teaching, and in the period of time, the video picture possibly does not change and no sound exists. In view of such circumstances, in the present application, when the video is processed, a sub-video with no audio information or low audio information volume is captured from the video, where no audio information indicates that the teacher does not speak, and low audio information volume may be a noise generated when the teacher performs writing or walks. Therefore, in the present application, intercepting a sub-video whose audio information meets a preset condition from video data may be implemented as: intercepting audio information of which the volume is smaller than a second preset threshold value in the audio information; and determining the video paragraph corresponding to the audio information with the volume smaller than the second preset threshold value as the sub-video meeting the preset condition.
The beneficial effect of this embodiment lies in: the video segment with small volume or without volume is used as the sub-video, so that the time of the user is saved through double-speed playing, the user is prevented from missing important audio information, and the user experience is further improved.
In one embodiment, as shown in FIG. 2A, the above step S12 can be implemented as the following steps S21-S22:
in step S21, acquiring a start time and an end time of a target video segment whose difference between adjacent video frames is smaller than a first preset threshold;
in step S22, the target video segment is acquired according to the start time and the end time.
Taking a teaching video as an example, as shown in fig. 2B, adjacent video frames a and B are extracted from a sub-video, and the adjacent video frames a and B are compared, as can be seen from fig. 2C, both the video frame a and the video frame B are pictures of a teacher performing a blackboard-writing operation, and the position and the posture of the teacher hardly change, assuming that in the teaching video, the teacher is performing the blackboard-writing operation all the time from 00:05:35 to 00:08:50 of the video playing time, and in the video section, the teacher does not speak and has no obvious position change, then, in the video section, the start time and the end time of a target video section of the adjacent video frames, which are smaller than a first preset threshold, are 00:05:35 and 00:08:50 respectively. Therefore, the target video passage 00:05:35 to 00:08:50 is obtained according to the start time and the end time.
In one embodiment, the above step S13 can be implemented as the following steps B1-B2:
in step B1, in the case that the current play mode is the first mode, determining the play double speed adapted to the target video paragraph;
in step B2, the target video segment is played based on the playback speed adapted to the target video segment.
In this embodiment, when the play mode is the first mode, the play speed adapted to the target video segment is determined, and the first mode may be a mode for automatically playing according to the adapted play speed. In this mode, when the playing speed adapted to the target video paragraph is determined, the target video paragraph is directly played based on the playing speed adapted to the target video paragraph without manual operation of the user.
It should be noted that, in the first mode, the playback speed of the target video segment may also be determined based on the type of the target video segment.
In one embodiment, the above step S13 can also be implemented as the following steps C1-C2:
in step C1, in the case that the current play mode is the second mode, determining the type to which the content played in the target video paragraph belongs;
in step C2, the playback speed of the target video segment is determined according to the type of the target video segment, and the playback speed of the target video segment is stored.
In this embodiment, when the current play mode is the second mode, the type to which the content played in the target video paragraph belongs is determined; and determining the playing speed of the target video paragraph according to the type of the target video paragraph, and storing the playing speed of the target video paragraph.
The second mode may be a mode for reminding the video viewer according to the adapted playback speed, that is, whether the playback at the speed is required or not, and the user needs to manually confirm the playback speed.
Of course, it is understood that the first mode and the second mode are exemplified for better describing and introducing the present application, the first mode may be a mode for reminding a video viewer according to the adapted play double speed, and the second mode may be a mode for automatically playing according to the adapted play double speed. This is not a limitation of the present application.
For example, the video data is a complete teaching video, and the change range of the posture and the position of the teacher is small in the video paragraph of the blackboard writing performed by the teacher, so that if the video paragraph is played at twice speed, important information cannot be missed, and the blackboard writing process can be smoother. For a video paragraph with almost unchanged picture, for example, a teacher leaves a video paragraph for students to think about problem time, the posture and position of the teacher hardly change, and the video paragraph is played at triple or quadruple speed, so that the time of a video viewer can be greatly saved; and when the type of the content played by the target video paragraph is determined to be the video paragraph of which the teacher reserves the problem thinking time for students, determining the playing speed of the target video paragraph to be triple speed.
In one embodiment, the above step S13 can also be implemented as the following steps D1-D2:
in step D1, when the current play mode is the second mode, obtaining historical behavior data of the user;
in step D1, the playback speed of the target video segment is determined based on the historical behavior data of the user, and the playback speed of the target video segment is stored.
In this embodiment, when the current play mode is the second mode, historical behavior data of the user is acquired; the historical behavior data is the historical operation behavior for double-speed playing when the user plays the video normally. And determining the playing speed of the target video paragraph based on the historical behavior data of the user, and storing the playing speed of the target video paragraph.
For example, when the user is displayed in the historical behavior data of the user, the user only plays at twice speed, but does not play at triple speed and quadruple speed, which indicates that the double-speed play is the play double speed used by the user habit, so as long as the target video paragraph is determined, the target video paragraph only adapts to the double-speed play double speed, and does not need to adapt to other play double speeds based on the type of the target video paragraph.
The beneficial effect of this embodiment lies in: the playing speed of the target video paragraph can be determined based on the historical behavior data of the user, so that the determined playing speed is more in line with the habit of the user.
In one embodiment, during video playback, the method may also be implemented as the following steps E1-E2:
in step E1, in the case of playing to the start time of the target video paragraph, acquiring the playing speed of the stored target video paragraph;
in step E2, a cue is issued based on the playback speed.
In this embodiment, since the playing speed of the target video segment is stored, the stored playing speed of the target video segment can be obtained when the target video segment is played to the start time; and sending out prompt information based on the playing speed.
In one embodiment, the step S13 can be further implemented as the following steps:
and marking the area corresponding to the target video paragraph on the video file playing progress bar according to the preset color.
In this embodiment, for the analyzed target video segment, a special color marking is performed on an interval corresponding to the progress bar, and when the video is played to the beginning of the segment, the corresponding playing double speed is selected based on the corresponding color, or a prompt is given on the interface, so as to prompt the user that the playing effect of the video segment at a specific double speed is better, and the user can select whether to play the video segment at the adapted double speed.
