Description
Technical field
The invention belongs to communication technical field, more particularly to a kind of video screen spinning solution and device.
Background technology
With flourishing for mobile Internet industry, increasing user replaces computer with mobile phone, wherein very big by one
Groups of people like seeing video with mobile phone, seen a film.But it is due to the limitation of mobile terminal, video can not be seen as computer
See, so by serial of methods, allowing user to have more preferable experience, just become the problem of developer.
Although the app of some present main flows has the function of played in full screen, but is all based on the vertical setting of types direction-locking of system
Function, and sometimes user only want to watch the app when can be by screen transverse screen played in full screen, when mobile phone falls back on backstage
When, other application is not influenceed, this is unable to handle, because this function is system level, thus have impact on it
He is app.There are following two defects in it：
1st, only set, screen transverse screen could be played, it is impossible to accurately know the current screen court of mobile phone by system
To automatic Rotation screen；
2nd, in said system application, if exiting current video playback, the setting that screen transverse screen is played also exists, if
Into other app, it is not necessary to which screen transverse screen is played, it is necessary to which change system is set again, and progress vertical setting of types direction-locking causes user
Operational inconvenience.
The content of the invention
In order to solve the above mentioned problem of prior art presence, the invention provides a kind of video screen spinning solution and dress
Put, there was only the technical problem that ability rotating mobile screen is set by system to solve mobile terminal in the prior art.

Embodiment
The present invention provides a kind of method and apparatus, and hand could be rotated to solve of the prior art only set by system
The technical problem of machine screen.
Technical scheme in the embodiment of the present application is solves above-mentioned technical problem, and general thought is as follows：Not by being
In the case of level operations of uniting, mobile phone direction, and automatic rotating mobile screen are calculated according to gyroscope.
In order to be better understood from above-mentioned technical proposal, below by accompanying drawing and specific embodiment to technical solution of the present invention
It is described in detail, it should be understood that the specific features in the embodiment of the present invention and embodiment are to the detailed of technical solution of the present invention
Thin explanation, rather than the restriction to technical solution of the present invention, in the case where not conflicting, the embodiment of the present invention and embodiment
In technical characteristic can be mutually combined.
Embodiment 1
As shown in figure 1, the present embodiment provides a kind of method video screen spinning solution, applied to mobile phone, including following step
Suddenly：
Screen three-dimensional data when S1, acquisition current video broadcasting；
S2, screen three-dimensional data when being played according to the current video, calculate and obtain current screen direction；
S3, according to the current screen towards Rotation screen.
Being only wanted in view of user can be by screen transverse screen played in full screen when app videos are watched, therefore the present embodiment
Screen three-dimensional data is only just obtained in video playback；Acquisition current screen direction is calculated according to screen three-dimensional data, can be with
Accurately know the current screen direction of mobile phone；According to current screen towards Rotation screen, it is not necessary to set by system, equally
The effect of transverse screen broadcasting can be obtained, and when exiting video playback, it is not required that system setting is changed again, can be reached certainly
The technique effect of dynamic Rotation screen.
As a kind of preferred scheme of above-described embodiment, step S1 can be obtained using 3-axis acceleration sensor works as forward sight
Acceleration of the screen on three-dimensional when frequency is played.3-axis acceleration sensor is such as gyroscope.
As another preferred scheme of above-described embodiment, step S1 can be the dimension of screen three of calling mobile phone system
According to.
Found in further investigation of the present inventor in the research present invention, some that can be carried by calling mobile phone system
Method persistently obtains the data of gyroscope.For example, iPhone system carries gyroscope, three dimensions of mobile phone can be known
According to, that is to say, that we can be according to the x in its coordinate system, y, tri- values of z, to judge the direction of equipment.
The main function of gyroscope, is to be based on conservation of angular momentum principle, along some specific reference axis measurement rotation speed
Rate.In use, the rotor of gyroscope points to a fixed direction, when the motion of moving object all the time when telling rotation
When predetermined direction is deviateed in direction, gyroscope can just be felt out.
That is, we can by force be drawn by a global variable by Video Controller to screen three-dimensional data
With, it is possible to ensure that the data of gyroscope can be continuously obtained during app is run.So it is also an advantage that, allows video
Controller strongly reference he, when we exit video playback interface, Video Controller can be destroyed, then his institute's strongly reference
All objects can all destroy, can so save many memory headrooms, allow app more lightweights, processing speed is faster.
Preferably, screen three-dimensional data when being played according to the current video, calculates and obtains current screen direction,
Including：When entering new app video playbacks every time, give tacit consent to the current screen and be oriented portrait layout upward, three-dimensional data is respectively
x、y、z；Three-dimensional data is persistently obtained, when z absolute value is less than critical value, starts to calculate, and make the following judgment：If y
Absolute value be more than x absolute value, judge that current screen towards being endways, if now y values are more than 0, represents currently to shield in z
Curtain is directed downward, and y values are less than 0, represents current screen direction upward；If y absolute value is less than x absolute value, judge current
Screen, towards being horizontal, if now x values are more than 0, represent current screen direction towards a left side, x values are less than 0, represents current screen in z
Curtain direction is towards the right side.
Specific algorithm is as follows：
A. the value of an enumeration type is defined：Value, carrys out recording equipment direction, the value acquiescence be portrait layout upward；
B. start to calculate (0.5 is critical value, represents equipment and starts rotation) when z absolute value is less than 0.5
C. judge, if y absolute value is more than x absolute value, then it is endways to prove equipment, now only needs to compare
If whether y values are more than 0. y values and are more than 0, device orientation is represented down, y values are less than 0, represent device orientation upward；
If d. y absolute value is less than x absolute value, then it is horizontal to prove equipment, now needs whether to compare x values
If being more than 0 more than 0. x values, device orientation is represented towards a left side, x values are less than 0, represent device orientation towards the right side.
Preferably, it is towards Rotation screen according to current screen：Call the screen control interface of the mobile terminal system, root
According to the current screen towards Rotation screen.Found by the further investigation of the present inventor, carry gyroscope for cell phone system, obtain
Know that cell phone apparatus after, can pass through [[UIDevicecurrentDevice] setValue:valueforKey:@"
Orientation "] method carrys out Rotation screen.
It is emphasized that above method step is not necessarily performed according to number order, why it is intended merely to numbering
The convenience of statement, as long as the purpose of the present invention can be realized, changing in any step should all be protected in the claim of the present invention
In the range of.
