For example, when stirring key and being in bar shaped outer rim one end, detects that the acceleration playing function key is opened, then execute step
Rapid S10；When stirring key and being in the bar shaped outer rim other end, detect that the acceleration playing function key is closed, then with video playing
Software current default speed plays the video to be played.
Step S20 chooses the target image frame of predetermined number from the picture frame of each time interval on time shaft；
For example, time interval is 1 second, a time interval includes 30 picture frames, at 1 second each from time shaft
Between section 30 picture frames in select the picture frame of predetermined number as target image frame, predetermined number can be one or more
It is a, preferably one.
Specifically, step S20 includes：
Step S21, obtains corresponding alternate image frame at the distributing position of each time interval on a timeline, and from it is each when
Between section alternate image frame in randomly select one, using the target image frame as each corresponding time interval.
When the duration of a time interval is smaller, the variation of the picture frame in time interval generally change it is relatively small,
In order to mitigate the calculation amount of subsequent image similarity comparison, can be chosen as possible from the alternate image frame in each time interval few
The target image frame of amount.For example, it includes 30 alternate image frames that time interval, which is in 1 second, 1 second, it can be from the 30 of each time interval
One is taken at random in a alternate image frame, is alternate image frame the 1st second on time shaft as target image frame, such as time interval
Frame 001 is followed successively by frame 030, randomly chooses target image frame of the spare frame 010 as the 1st second time interval, then similarly according to
It is secondary to recycle the target image frame for selecting follow-up time section.For another example, time interval is the one third second, and video to be played has ten
Minute, each second, 30 frame extracted for 10 minutes then 3 frames of extraction per second (i.e. 3 target image frames), extract 180 frames for one minute
1800 frames (i.e. 1800 target image frames).
Step S30, the target image frame adjacent to sequential on time shaft carry out image similarity comparison, obtain each adjacent
Similarity value between target image frame；
Sequential can be played according to time shaft epigraph frame, image similarity ratio is carried out to adjacent target image frame successively
It is right, need to only similarity comparison be carried out to continuous target image frame, picture frame all in video to be played need not be carried out
Similarity compares, to obtain the similarity value between each adjacent target image frame.Such as choose video to be played 1st second extremely
After 3rd second target image frame, image similarity comparison is carried out to first three seconds target image frame, is completed simultaneously when comparing
After obtaining the similarity value between first three seconds each adjacent target image frame, continue to choose video to be played 4th second extremely
6th second target image frame carries out image similarity comparison, and so on, the similarity ratio until completing all target image frames
It is right, obtain the similarity value between all adjacent target picture frames.
Step S40, time interval where similarity value is more than the target image frame of pre-set threshold value add as time shaft
Fast section carries out default acceleration to the picture frame in the acceleration area and plays during playing the video to be played.
It determines that similarity value is more than the target image frame of predetermined threshold value, and similarity value to each other is more than predetermined threshold value
Time interval where target image frame is set as the acceleration area of time shaft, and wherein similarity value is more than the target figure of predetermined threshold value
As closely similar between frame, i.e. difference between two target image frames is smaller, and similarity value is bigger.To at video to be played
When broadcast state, when playing to acceleration area, default acceleration is carried out to the picture frame in acceleration area and is played.
In the present embodiment, by being scanned to video to be played, obtain along on video time axis to be played successively
Picture frame in each time interval of distribution；Then the mesh of predetermined number is chosen from the picture frame of each time interval on time shaft
Logo image frame；The target image frame adjacent to sequential on time shaft carries out image similarity comparison again, obtains each adjacent target
Similarity value between picture frame；Time interval where similarity value is finally more than the target image frame of pre-set threshold value as when
The acceleration area of countershaft carries out default acceleration to the picture frame in acceleration area and plays during playing video to be played, from
And compared based on image similarity, automatic identification is carried out to acceleration area in video to be played, to accurately determine acceleration area
In static scene the picture frame of static scene in acceleration area is carried out and in video playing to be played to acceleration area
It is default to accelerate to play, such as it is unified in the picture frame played in 1.5 seconds in current acceleration area, avoid user to not changing
Static scene checked and waited for for a long time, carrying out complicated and inaccurate switching to the video of broadcasting without user grasps
Make, improves the viewing experience of user.
Such as in the shooting video of fireworks, the following period of time of spark is bought after fireworks point combustion wire and is not discharged,
Fireworks in video do not change, at this time can be to carrying out acceleration broadcasting this period.
Further, in another embodiment of video playing control method of the present invention, step S30 includes：
Step S31 analyzes the picture frame in video to be played, determines the core pair in video image frame to be played
As and auxiliary object and kernel object and auxiliary object the first weight and the second weight in similarity comparison respectively, the
One weight is more than the second weight；
Two adjacent target image frames on time shaft are divided into a comparison group, two targets in each comparison group by step S32
The kernel object of picture frame and auxiliary object carry out image similarity comparison respectively, obtain the kernel object similarity of each comparison group
Value and auxiliary object similarity value；
Step S33 obtains the first product value, the auxiliary object phase of each comparison group kernel object similarity value and the first weight
Like the second product value of angle value and the second weight, by the sum of the first product value and the second product value as the similar of corresponding comparison group
Angle value.
Such as it is the personage shot to play in video, then can determine that personage is kernel object, personage is in similarity comparison
First weight is more than 0.5, such as the first weight is 0.7, it may be determined that the background where personage is auxiliary object, and the second weight can be
0.3。
Such as have 6 time intervals on the time shaft of video to be played, it is section A, interval B, area respectively successively in sequential
Between C, section D, section E and section F, the target image frame of each time interval is respectively frame a, frame b, frame c, frame d, frame e and frame f,
To which frame a and frame b is a comparison group, frame c and frame d are a comparison group, and frame e and frame f are a comparison group, then three ratios
The image similarity for carrying out kernel object and auxiliary object respectively to the target image frame in group compares, and can be obtained frame a's and frame b
The kernel object similarity value 90 of kernel object similarity value 80, auxiliary object similarity value 80, frame c and frame d, auxiliary object phase
Like angle value 50, kernel object similarity value 50, the auxiliary object similarity value 80 of frame e and frame f.First to frame a and frame b multiplies
Product value=80*0.7=56, the second product value=80*0.3=24, to which the similarity value of comparison group where frame a and frame b is 80；
The similarity value of comparison group is 78 where frame c known to similarly and frame d, and the similarity value of frame e and the places frame f comparison group is 59, if
Pre-set threshold value is 70, then acceleration area of the time interval as time shaft, frame e and frame f where frame a and frame b and frame c and frame d
Acceleration area of the place time interval not as time shaft.
In the present embodiment, the classification of kernel object and auxiliary object is carried out to the content in picture frame, and assigns core
The object weight different with auxiliary object, influence when to weaken that auxiliary object changes in picture frame to similarity value,
When user is less concerned about that auxiliary object changes i.e. in picture frame, still by the changed picture frame institute of auxiliary object
In time interval as acceleration area, the static scene for the variation for avoiding user not noticeable falls into a long wait.
Optionally, time interval where similarity value being more than the target image frame of pre-set threshold value in step S40 as when
The step of acceleration area of countershaft includes：
Step S41 selects target image frame place time interval of the similarity value more than pre-set threshold value on a timeline, will
The time interval selected is as standby time section；
Step S42 merges standby time section adjacent on time shaft, generates new standby time section, directly
All standby time sections are non-conterminous on to time shaft；
Step S43, using all standby time sections on current time axis as the acceleration area of time shaft.
Connect step S33 examples below, the similarity value of comparison group compares where being 80, frame c and frame d where frame a and frame b
The similarity value of group is 78, the similarity value of comparison group is 59 where frame e and frame f, if pre-set threshold value is 70, frame a and frame b,
And time interval where frame c and frame d is standby time section, then by two standby times of frame a and frame b and frame c and frame d
An acceleration area is merged into section, completes the merging between the adjacent time interval for meeting preset threshold condition to form one
Acceleration area is avoided to carrying out repeating label in an acceleration area, and then is avoided to the anti-of the default acceleration processing of acceleration area
It is multiple to start or close.
Further, in the another embodiment of video playing control method of the present invention, to be played regard is being played in step S40
During frequency, carrying out the step of default acceleration plays to the picture frame in acceleration area includes：
Step S44, to each acceleration area at the time shaft at the beginning of point addition beginning label, add at end time point
End is added to mark；
Step S45, during playing video to be played, if detecting beginning label, to the time where beginning label
Picture frame after point carries out default acceleration and plays；
Step S46 restores to current picture frame after terminating time point where marking if detecting end label
Default speed plays.
After determining acceleration area on the time shaft of video to be played, to all acceleration areas at the beginning of time shaft
Between addition beginning label at point, addition terminates label at end time point, beginning label and to terminate label be electronic marker, with
The reproduction time range that acceleration area is identified for playout software, to during playing video to be played, if detecting beginning
Label then carries out default acceleration to the picture frame after time point where beginning label and plays；It is right if detecting end label
Terminate the picture frame where label after time point to restore to current default speed to play, provide a kind of realizations accelerate to play with
Default speed plays the technical solution of switching.
In addition, being merged to multiple adjacent acceleration areas, the acceleration area new as one, multigroup open can be arranged less
Begin label and end label, and during playing video to be played, due to unnecessary beginning label and terminates subtracting for label
Less, it is soft to improve broadcasting without switching repeatedly between accelerating broadcasting and default speed to play both of which repeatedly for playout software
The realization difficulty of part.
Optionally, step S45 includes:
Step S451, if detecting beginning label, it is determined that it is pre- under current default speed to be currently located acceleration area
Playing duration；
Step S452, according to pre- playing duration and default acceleration playing duration, determination is currently located acceleration area picture frame
Target broadcasting speed；
Step S453 plays out the picture frame after time point where beginning label with target broadcasting speed, until
Detect end label.
Default acceleration playing duration can be that system setting or user are voluntarily arranged, and enter the broadcasting stage in video to be played
Afterwards, if detecting beginning label on a timeline, show that acceleration area will be entered, the acceleration area that determination will enter is being worked as
Required pre- playing duration is finished under preceding default speed (i.e. the broadcasting speed of playout software current default), is then determined
Pre- playing duration and the default duration ratio for accelerating playing duration, determine the current default speed of duration scalar multiple for current institute
In the target broadcasting speed of acceleration area picture frame, then to being currently located after acceleration area beginning label place time point
Picture frame is played out with target broadcasting speed, until detecting end label.The acceleration to acceleration area is realized to play.
Such as after detecting beginning label, determine that the pre- playing duration of acceleration area is 6 seconds, default acceleration playing duration is
1.5 seconds, duration scalar multiple was 4, to which target broadcasting speed need to be 4 times of current default speed, and then to beginning label institute
Picture frame after time point is played out with 4 times of current default speed, until detecting end label.That is, pre-
If it can detect acceleration area to accelerate playing process, acceleration area accelerates playing duration to play for 1.5 seconds with default
Finish, as acceleration area pre- playing duration be 3 seconds when, target broadcasting speed need to be 2 times of current default speed.
Optionally, step S44 adds beginning label, end time to each acceleration area at time shaft at the beginning of point
Addition, which terminates to mark, at point includes later：
Beginning label and end label are shown on the broadcasting item of video to be played, cut if being detected at beginning label
Operation is changed, then will directly skip the successive image frame after beginning label, playing progress rate is switched to and detects that handover operation is opened
Begin to mark associated end mark.
Such as an acceleration area includes beginning label B and terminates label E on video time axis to be played, by beginning label
B and end label E are shown in the form of visual marker on the broadcasting item of video to be played, if at beginning label B or opening
Begin to detect handover operation input by user between label B and end label E, then playing progress rate is directly switch into end label
E provides a kind of implementation being switched fast acceleration area, the duration of acceleration area is longer, the patient lower scene of user
Under have positive effect.If handover operation is not detected from after beginning label B, after time point where beginning label
Picture frame carries out default acceleration and plays, until detecting end label, the then picture frame after time point where being marked to end
Restore to current default speed to play.
