When the broadcasting page is laterally pulled, i.e., user is not put and is released when laterally pulling a certain distance by clicking the key on mouse
Mousebutton is put, just judges that user is to carry out progress adjustment operation to target video.
Certainly, progress adjustment is operated, the present embodiment is specifically to be illustrated with laterally pulling operation, specific real
During applying, progress adjustment can also be realized by others operation, for example be also possible to: first be clicked at video playing interface
One position, clicks another position again within a preset time, then then judging this operation for progress adjustment operation, to progress tune
The specific implementation of whole operation, the present embodiment are not specifically limited.
When S220. obtaining the progress adjustment operation beginning, when first corresponding to the playback progress of the target video
Between point.
Progress adjustment operation is a process, and having operation beginning and operation terminates, or for laterally pulling, works as end
End detect video playing interface exist laterally pull operation when, record laterally pull operation start when, target video is worked as
First time point corresponding to preceding playback progress, i.e., it is currently playing by which point several seconds.
S230. initial position and the final position of the progress adjustment operation are determined.
The problem of being operated for video playing interface, operating position will be related to.User is started in video circle
Position when being operated on face is determined as initial position, and user is stopped at position when operating in video clip and is determined
For final position.When progress adjustment operation is laterally pulls, and when detecting the operation laterally pulled, it will test and laterally drag
Position when dynamic beginning is determined as the initial position, will test the position at the end of laterally pulling and is determined as the stop bit
It sets.
Determination for specific location is established a right angle and is sat using the certain point on the video playing page as coordinate origin
Mark system.Using the lower left corner of the video playing page as coordinate origin in the present embodiment, coordinate system is established, refers to Fig. 4, it is assumed that laterally
The operation of dragging terminates since A point to B point, can learn that the coordinate of initial position A point is (x1,y1), final position B point
Coordinate is (x2,y2)。
S240. according to the first time point, the initial position and the final position, after determining progress adjustment
Second time point.
When progress adjustment operates beginning, the time point of corresponding playback progress is first time point, then in progress tune
At the end of whole operation, the time point after corresponding adjustment was the second time point, and the second time point here cannot directly acquire
It arrives, needs to operate adjusted lateral distance according to progress adjustment to obtain, refer to Fig. 5, it illustrates a kind of progress adjustments
Time point calculating method afterwards, comprising:
S510. the distance of the initial position and the final position is calculated.
Here distance refers to the lateral distance of initial position and final position, as shown in Figure 6:
If with A (x1,y1) point be starting point, slide laterally to the right, slide into B (x2,y2) point, A point and B point may not
On a horizontal linear, i.e. the value of the ordinate of A point and B point is unequal, only needs to pay close attention to the abscissa of A point and B point here
Value, pass through calculate x2-x1To determine the lateral distance between A point and B point.
If with A (x1,y1) point be starting point, slide laterally to the left, slide into C (x3,y3) point, it is same to calculate A point and C
The lateral distance of point is x3-x1。
The lateral distance calculated here come out can just be born, and be only intended to indicate a kind of distance relation.
S520. the distance was converted as the period.
Assuming that the distance between two o'clock calculated is x, need to convert this distance for corresponding period, Ke Yili
Solution are as follows: by the lateral distance x between two o'clock multiplied by coefficient a, obtain corresponding time period t.
Specifically, coefficient a can be determined by following mode:
Assuming that the total duration of currently playing target video is T, and it is L that target video, which plays the transverse width of the page, that
Just have:
For example, the total duration of currently playing target video is T=600s, the transverse width for playing the page is L=5cm,
So for current video,
If the operation of currently detected progress adjustment be slide to the right, and the lateral distance between two o'clock is x=1cm, then
For this apart from the corresponding period are as follows:
t1=xa=1120=120s (3)
If currently detected progress adjustment operation is to slide to the left, and the lateral distance between two o'clock is x=-1.5cm, that
For this apart from the corresponding period are as follows:
t2=xa=-1.5120=-180s (4)
By above-mentioned calculating, the period corresponding to the distance that can be slided.
S530. according to the first time point and the period, second time point is obtained.
After obtaining the period according to above-mentioned calculation method, the corresponding time is added on the basis of first time point
Section, the second time point after being adjusted.
Assuming that the corresponding first time point of the playback progress of target video is 200s when carrying out progress adjustment operation
Place.
It is 120s, then after progress adjustment for sliding laterally to the right shown in period corresponding to 1cm such as formula (3)
Second time point was 200s+120s=320s.
Be -180s for being slid laterally shown in period corresponding to -1.5cm such as formula (4) to the left, then progress adjustment it
The second time point afterwards is 200s-180s=20s.
The above-mentioned calculation method about the time point after progress adjustment is according to actual physical distance come when calculating
Between put, the method that a kind of above-mentioned time point determines can also have another embodiment, reference can be made to Fig. 7, comprising:
S710. the interval pixel values between initial position and final position are determined.
Here interval pixel values, which refer to, slides laterally to another point pixel experienced from a bit, spaced pixels here
A kind of form of expression of distance can also be regarded as.
S720. according to the interval pixel values and systemic presupposition parameter, the interval pixel values were converted as the period.
Systemic presupposition parameter needs to carry out system setting in advance, for example, this parameter can be set to 15 pixels/s,
Its meaning is to slide laterally 15 pixels, and the corresponding period is 1s.Sliding to the left is rewind, and sliding is F.F. to the right, when to the right
When sliding laterally 300 pixel, actual play progress F.F. 20s.Here period be also divided into it is positive and negative, when system detection to
When sliding laterally of a left side, the period is negative；When system detection is to when sliding laterally, the period is positive to the right.
S730. according to first time point and period, the second time point after progress adjustment is determined.
First time point is added into the corresponding period, the second time point after being adjusted.
It should be noted that above-mentioned progress adjustment operation needs to operate in the effective coverage that target video plays the page
It can just be detected, the operation except effective coverage is then invalid.
S250. the second preview picture of the target video corresponding with second time point is obtained.
It can be stored with the frame collections of pictures of target video in the server, and establish pair of each frame picture and each time point
It should be related to, in order to which the corresponding frame picture of time point picking after progress adjustment operation can be carried out according to user.
The specific method for obtaining preview picture can be found in Fig. 8, comprising:
S810. it searches to whether there is in memory and has second preview picture corresponding with second time point.
Locally searching whether that frame picture corresponding with time point is corresponded to when existing there are in target video first
Frame picture, then the frame picture is determined as preview picture corresponding with the time point.Each time in target video
Point has corresponding preview picture, can be an a time point corresponding preview picture, is also possible to multiple time points
A corresponding preview picture.Latter approach can be reduced the quantity of preview graph, mitigate storage pressure, and general shorter time model
It encloses interior plot variation less, the video content in time period also can be preferably expressed with a hypertonic sketch map.
S820. when second preview picture is not present, institute corresponding with second time point is downloaded from server
State the second preview picture.
When frame picture corresponding with the time point is not present in local memory, need to obtain from server side.It is first
The information for first needing to find the related target video in server according to the mark of target video, then further according to the time
Point is to obtain corresponding frame picture as preview picture.The target can also be regarded after finding the information of target video
The frame collections of pictures of frequency is cached to local memory and does not need continually in this way in the acquisition operation for carrying out multiple preview picture
Getting frame picture is removed from server, has saved the time, efficiency is improved, but certain local memory can be occupied.
During progress adjustment, may there is a situation where it is such, when sliding laterally to the left, according to first time point
And the period, the second obtained time point is less than 0, then it is determined that the first frame picture of video is the corresponding preview of the second time point
Picture；When sliding laterally to the right, according to first time point and period, obtained the second time point be greater than video it is total when
It is long, then it is determined that the last frame picture of video is the second time point corresponding preview picture.
S260. second preview picture is shown.
