Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
The first embodiment of the invention relates to a video playing method which is applied to a server. The following describes implementation details of the video playing method of the present embodiment in detail, and the following is only provided for easy understanding and is not necessary to implement the present embodiment.
A flowchart of the video playing method in this embodiment is shown in fig. 1, and specifically includes:
step 101: and segmenting the video according to the shooting lens to obtain a plurality of video segments.
It is understood that in the process of capturing video, a capture shot captures a continuous video frame, which may also be referred to as a shot. In this step, the plurality of video segments obtained by segmenting the video may be understood as a plurality of shots of the video.
In one example, the segmented video may be a video being played by the client, that is, a video being played by the user. When a user watches a video, if the user wants to change the playing sequence of the video, a request can be sent to the server, and the server can start to execute the step after receiving the request. For example, a function key for changing the playing sequence may be set on the playing interface of the client, and if the client detects that the function key is pressed, the video being played is paused, and the step is started to be executed. Wherein, the dividing the video may be: the subsequent video content is segmented starting from the playing position where the video was paused.
In one example, the video may be divided in the following manner: the method comprises the steps of obtaining the similarity between any two adjacent video frames in a video, determining the time point of shot switching according to the similarity, and segmenting the video according to the time point of shot switching to obtain a plurality of video segments. For example, the image similarity between the current frame and the next frame may be detected frame by frame, when the image similarity is lower than a preset similarity, the shot is regarded as being switched, the time point of the shot switching is recorded, and finally, the video is segmented according to the recorded time point of the switching to obtain a plurality of video segments. The similarity between any two adjacent video frames can be determined by combining scene characteristics, character characteristics, lines of speech characteristics, plot characteristics and the like between the two adjacent video frames.
In a specific implementation, a duration between two adjacent switching time points may also be recorded, that is, a duration of a video clip between two switching time points, which may also be referred to as a duration of a shot. In addition, after the plurality of video clips are obtained through division, the plurality of video clips can be numbered according to the original playing sequence of the plurality of video clips. For example, the video clips are divided into N video clips, the numbers of the video clips are 1,2, and 3 …. In a specific implementation, the information such as the time point of each shot switching, the shot duration, the shot number, and the like may be stored in an xml format, a json format, and the like.
In another example, the manner in which the video is partitioned may be as follows:
first, a video frame is selected as a reference video frame in a video, and a reference area is selected in the reference video frame. For example, a video frame corresponding to the paused video may be used as a reference video frame, and a reference area may be selected from the reference video frame. In one example, the reference area may be selected by: and selecting a reference object in the reference video frame, wherein the reference object can be a relatively prominent person or object in the video frame. Then, selecting a reference area in an area outside the reference object; the color value feature of the reference region is a non-single color value, that is, a non-solid color region can be selected as the reference region to improve the reference meaning of the selected reference region, that is, the non-solid color region is selected as the reference region, so that whether the image feature of the reference region changes or not can be easily detected.
Referring to fig. 2, 16 consecutive video frames in fig. 2 are selected as the reference video frame, the person in the picture is identified by the person identification method, and color value features of the small block region are randomly extracted from the places other than the person. Then, validity check of the color value feature may be performed, for example, when the color value feature of the randomly extracted small block area is a single color value, the feature is considered to be invalid and needs to be extracted again. The size of the small block region may be 48 × 48 or 64 × 64, which is not specifically limited in this embodiment. The reference area selected in the first video frame in fig. 2 is illustrated as a boxed area.
Then, from the reference video frame, image features of the reference region in the video frame are extracted frame by frame. Referring to fig. 2, starting from the first video frame, image features of a reference region in the video frame, that is, image features of a region framed by a square frame in each video frame are extracted frame by frame.
Then, according to the degree of change of the extracted image features, a switching video frame is determined, and the switching video frame is used as a reference video frame. It is understood that when the image scene is displaced, such as when the lens is switched, the image characteristics of the reference area may be changed to a greater extent. Referring to fig. 2, the last two video frames in the 4 th row have a larger degree of change in image features due to the fact that the reference region is occluded by a person, at this time, the second last video frame may be determined as a switching video frame, and the second last video frame is used as a reference video frame, a reference region, i.e., a region framed by a square frame on the right side of the person in the drawing, is reselected from the second last video frame, then the image features of the reference region in the video frames are extracted frame by frame from the beginning of the second last video frame, and the above process is repeated until the image features of the last video frame of the video are extracted. It will be appreciated that a plurality of switching video frames may be determined in this process.
And finally, segmenting the video according to the switching video frame to obtain a plurality of video segments. For example, a video between two adjacent switching video frames is segmented to obtain a video segment, and finally, a plurality of video segments are obtained.
Step 102: and determining playing addresses corresponding to the plurality of video clips respectively.
Specifically, the start time stamps and the end time stamps of the plurality of video segments can be obtained, and the playing addresses corresponding to the plurality of video segments are determined according to the start time stamps and the end time stamps. It can be understood that each video segment corresponds to a start time stamp and an end time stamp of playing, hereinafter referred to as start-stop time stamps, in the whole video, and the playing data between the start-stop time stamps may correspond to a playing address, through which the corresponding playing data may be downloaded. In a specific implementation, the access address of the video may be represented by a Uniform Resource Locator (URL), and the play addresses corresponding to different video segments may be determined by the URL and start-stop timestamps corresponding to the different video segments.
In one example, each video clip may be provided with a respective number. For example, after obtaining a plurality of video segments, the plurality of video segments may be numbered, and in a specific implementation, each video segment may be numbered according to an original playing order of the plurality of video segments, and each number may correspond to one playing address.
Step 102: and acquiring the adjustment information, and adjusting the playing sequence of the plurality of video clips according to the adjustment information.
In one example, the adjustment information may be a deletion, a recovery, a shift-forward, a shift-backward, etc. operation of the video segment. The client may send an adjustment request to the server, where the adjustment request may carry adjustment information. For example, a plurality of video clips are all provided with corresponding numbers, and assuming that 5 video clips are obtained by multi-video segmentation, the numbers are: 1 to 5, and the original playing sequence of the 5 video segments is: 1. 2,3, 4 and 5. The adjustment request may carry the number and operation of the video segment to be adjusted, such as "delete number 1", "interchange number 3 and number 5". The server adjusts the playing sequence of the plurality of video clips according to the adjustment information, and the adjusted playing sequence is as follows: 2. 5, 4, and 3, namely, the video segment corresponding to the number 1 is masked, which indicates that the video segment corresponding to the number 1 is not played any more after adjustment, and the playing sequence of the video segments corresponding to the numbers 3 and 5 is interchanged.
Step 103: and playing the plurality of video clips according to the adjusted playing sequence.
For example, when the user determines to play the shots according to the adjusted playing sequence, the user continues to play the subsequent shots from the currently playing shot according to the new playing sequence. Specifically, the server may push a plurality of video clips to the client according to the adjusted playing order. In the above example, the adjusted playing sequence is: 2. for example, 5, 4, and 3, the server may sequentially push the video clips 2, 5, 4, and 3 to the client according to the playing duration corresponding to each video clip, that is, the shot duration.
In an example, it can be understood that each video segment corresponds to a start time stamp and a stop time stamp of playing, hereinafter referred to as a start-stop time stamp, in the whole video, and the playing data in the start-stop time stamp may correspond to a playing address, through which the corresponding playing data can be downloaded. The server can sequentially issue the playing addresses corresponding to the video clips after the sequence is adjusted to the client, so that the client can download corresponding playing data. If a plurality of video segments are numbered according to the original playing sequence, each number may correspond to a playing address of one video segment. The server can obtain the number sequence corresponding to the adjusted playing sequence, and sequentially sends the playing addresses corresponding to the numbers to the client according to the number sequence. Such as. When the client sends a request for restoring playing of the video to the server, the client can carry the number of a next shot, namely a video clip, and the server sends a playing address corresponding to the number of the shot after receiving the request.
The above examples in the present embodiment are only for convenience of understanding, and do not limit the technical aspects of the present invention.
Compared with the prior art, the embodiment divides the video according to the shooting lens to obtain a plurality of video clips; considering that the video segments shot by the same shooting lens are usually consecutive segments, the video is segmented according to the shooting lens, and the consistency of each of the obtained video segments is better. Then, determining playing addresses corresponding to the plurality of video segments respectively, acquiring adjustment information, adjusting the playing sequence of the plurality of video segments according to the adjustment information, and adjusting the playing sequence of the plurality of divided video segments, namely, changing the playing time of each video segment on the whole according to the adjustment information, and playing the plurality of video segments according to the adjusted playing sequence and playing addresses, so that the adjustment of the playing sequence can be realized without performing secondary editing on the video, decoding and recoding caused by the secondary editing are avoided, and the process of adjusting the playing sequence is simpler.
A second embodiment of the present invention relates to a video playback method. The following describes implementation details of the video playing method of the present embodiment in detail, and the following is only provided for easy understanding and is not necessary to implement the present embodiment.
A flowchart of the video playing method in this embodiment is shown in fig. 3, and specifically includes:
step 201: and segmenting the video according to the shooting lens to obtain a plurality of video segments.
Step 202: and determining playing addresses corresponding to the plurality of video clips respectively.
Step 201 and step 202 are substantially the same as step 101 and step 102 in the first embodiment, and are not repeated here to avoid repetition.
Step 203: and pushing preview pictures of a plurality of video clips to the client.
Specifically, a display interface of the client may be provided with a function key for requesting preview, and when it is detected that the function key is triggered, the client sends a preview request to the server, and the server pushes a preview screen of a plurality of video clips to the client. The preview picture of each video clip can be a few continuous pictures of the first frame of each video clip, or can be a continuous picture of all frames. The display interface of the client side can comprise at least two preview areas which are used for circularly playing the preview pictures of the video clips. The server can sequentially send the playing addresses of the video clips to the client according to the original playing sequence of the video clips, so that the video clips can be downloaded by the client and then displayed for the user to preview.
In one example, the server may determine a first area of a display interface of the client and a second area of a preview screen, and determine the number of preview areas on the display interface according to the first area and the second area; wherein different preview areas are used for previewing different preview screens. That is, it is calculated how many shots can be displayed at most in the display interface according to the size of the display interface and the size of the preview screen. And then sequentially pushing the preview pictures of the multiple shots to the client so as to preview the preview pictures of the multiple shots through different preview areas.
Referring to fig. 4, when the user clicks a function key for requesting a preview on the display interface of the client, the display interface jumps from the left form to the right form in fig. 4. As can be seen from fig. 4, there are 6 preview areas on the display interface, and the user can play 6 preview pictures. It can be understood that, if there are more than 6 video segments obtained by splitting a video, the server may first push 6 preview pictures to the client, and when an operation such as a slide-up or a slide-down operation on the preview area is detected, may push a new preview picture to the preview area where the operation such as the slide-up or the slide-down operation is detected.
Step 204: and acquiring the adjustment information of the preview picture.
Specifically, if it is detected that a preview area is triggered, a preview picture in the triggered preview area is used as a picture to be adjusted. For example, if it is detected that a preview area is pressed for a long time, it may be determined that a preview screen in the preview area is selected, and the selected preview screen may be adjusted to be translucent. Referring to fig. 5, the preview screen 3 is selected as a to-be-adjusted screen, and when the preview screen 3 is dragged to a position outside the current preview area, the subsequent preview screens are sequentially moved forward to replace the previous one.
If the picture to be adjusted is detected to be moved to the deletion area, the obtained adjustment information is as follows: deleting the picture to be adjusted and playing a new preview picture in the triggered preview area; if the picture to be adjusted is detected to be moved out of the deletion area, the obtained adjustment information is as follows: and restoring the picture to be adjusted. Referring to fig. 5, a garbage collection area, that is, a deletion area, is displayed at the lower left of the display interface, and the preview screen moved to the deletion area indicates that the video segment corresponding to the preview screen is not requested to be played finally. In addition, the preview screen dragged to the deletion area may exist in a number manner, or the number may be dragged out of the deletion area to resume playing. Referring to fig. 6, a preview screen 3 is displayed in the deletion area as number 3. The new preview screen played in the triggered preview area may be the subsequent preview screen 4, or may be a preview screen not currently displayed on the display interface, for example, the new preview screen 7.
If the picture to be adjusted is detected to be moved to another preview area, the obtained adjustment information is as follows: and interchanging the triggered preview area and the preview screen played by the other preview area. For example, when the screen to be adjusted is dragged to overlap with other preview screens at a preset overlap ratio such as 1/4, the two parties exchange the preview screens being played.
Step 205: and adjusting the playing sequence of the plurality of video clips according to the adjustment information of the preview picture.
For example, the arrangement order of the preview pictures on the current display interface may be used as the playing order of the adjusted video clips. Referring to fig. 6, the preview images on the current display interface are arranged in the following order: in preview images 1,2, 4, 5, and 6, the playing order of the plurality of video clips is: video segments 1,2, 4, 5, 6, i.e. video segment 3 is deleted.
