Refer to Fig. 3, in one embodiment, described Media Stream control method for playing back also comprises the steps.
Step S50: the motion monitoring described predetermine one.
In the present embodiment, incoming event causes the motion of predetermine one, may cause different functions, and monitor the motion of predetermine one, motion that just can be different according to predetermine one, starts corresponding function.Concrete, be exemplified as: predetermine one is moved to another location from current location, if this another position is the border of display, then may trigger the hidden function of predetermine one; Predetermine one is moved to the toolbar of software from current location, then predetermine one may be made to be embedded in toolbar; Predetermine one is rotated, then may trigger the function that progress regulates.Certainly, also only can monitor whether predetermine one there occurs rotation, find that predetermine one there occurs rotation, then trigger progress regulatory function.
Step S60: when described predetermine one rotates, regulates current playing progress rate.
In the present embodiment, predetermine one rotates, then trigger progress regulatory function.Predetermine one response incoming event rotates, and can be the geometry center rotating relative to predetermine one, the angle of rotation can be arbitrarily angled.When the rotation direction of predetermine one is clockwise, can for regulate progress forward, the end be towards current played file regulates playing progress rate, and the rotation direction of predetermine one is for be counterclockwise, for to regulate progress backward, the initial adjustment playing progress rate towards current played file can be.

Step S62: regulate playing progress rate according to described current operation angle.
In the present embodiment, adjustment playing progress rate can be carried out in the rotation process of predetermine one, namely calculate a current operation angle at interval of a set time, adjust progress immediately, also can terminate for the rotation of predetermine one, after calculating rotational angle, then regulate playing progress rate.The amplitude of accommodation of playing progress rate, can determine according to the size of rotational angle.
Refer to Fig. 6, in one embodiment, described step S62 also comprises following sub-step.
Step S621: current operation angle is compared with references angle.
Step S623: described current operation angle is greater than described references angle, playing progress rate is regulated the first scheduled duration.
In the present embodiment, references angle for the angle value pre-set, if current operation angle is greater than references angle, can show that needs regulate for playing progress rate, if current operation angle is less than references angle, does not regulate playing progress rate.In the process that video or audio file are play, user may misoperation cause predetermine one to rotate accidentally, by arranging references angle, can to a certain degree avoid this misoperation to cause regulating playing progress rate.The value of references angle can be 5 degree, 10 degree, 15 degree or 20 degree, and certainly, the value of references angle can also have other value, will not enumerate as space is limited at this.
In the present embodiment, the first scheduled duration is the amplitude regulated playing progress rate, its time span can specified for any one, such as 1 second, 2 seconds, 3 seconds ... 15 seconds, 16 seconds ... 30 seconds etc., no longer enumerate as space is limited at this.In the process regulating playing progress rate, in conjunction with the rotation direction of predetermine one, playing progress rate can be regulated forward or backward.Concrete, be exemplified as: rotate if predetermine one is clockwise direction, direction then towards current played file end regulates playing progress rate, by the time coordinate of current broadcasting increase the first scheduled duration adjusted after time coordinate, if after current time coordinate increases by the first scheduled duration, be more than or equal to the total length of current played file, then the time coordinate after regulating is the time coordinate at most end.If predetermine one is counterclockwise rotate, then regulate playing progress rate towards the direction that current played file starts, by the time coordinate of current broadcasting reduce the first scheduled duration adjusted after time coordinate, if after current time coordinate reduces the first scheduled duration, be less than or equal to zero, time coordinate after then regulating is zero, namely plays from the beginning of current played file.
In the present embodiment, described step S62 can also comprise sub-step S625: described current operation angle is less than described references angle, playing progress rate is regulated the second scheduled duration, and the second scheduled duration is less than the first scheduled duration.Current operation angle is less than references angle, show that needs carry out adjustment by a small margin for playing progress rate, so the second scheduled duration can be less than the first scheduled duration, so degree of regulation can be improved, moreover realize to carry out accurate adjustment and coarse adjustment to playing progress rate by the difference of predetermine one rotational angle, improve the experience of user.Regulated by playing progress rate the second scheduled duration also can in conjunction with the rotation direction of predetermine one, principle, with the description of aforementioned adjustment first scheduled duration, no longer repeats as space is limited at this.The value of the second scheduled duration is less than in the first scheduled duration, specifically can set according to actual conditions.
Refer to Fig. 7, in one embodiment, described step S62 can also comprise following sub-step.
Step S622: the rotational angle of described predetermine one has span, the data in described span are corresponding with a time coordinate of current played file respectively, obtain the time coordinate that current operation angle is corresponding.
Step S624: regulate playing progress rate to the time coordinate corresponding with described current operation angle.
In the present embodiment, the rotation of predetermine one can be rotate around a center of circle, then can define a maximum rotation angle, can think span from 0 degree to maximum rotation angle.The value of maximum rotation angle can be 180 degree, 360 degree, 540 degree or 720 degree etc., will not enumerate as space is limited at this.
In the present embodiment, each rotational angle of predetermine one is corresponding with a time coordinate of current played file, then in the process of current played file broadcasting, predetermine one itself also rotates along with playing progress rate, so can show the progress of broadcasting to user.When predetermine one is because of after the control command of input rotates, playing progress rate is adjusted to rotate after time coordinate corresponding to rotational angle.In the present embodiment, if the maximum rotation angle of predetermine one is A, then the span of rotational angle is from 0 to A, if there is overall time length L in current played file, if current operation angle is C, if time coordinate corresponding to current operation angle is T, then the time coordinate that current operation angle is corresponding can be expressed as following formula.
In above formula, current operation angle C is the rotational angle of predetermine one relative to original position, and wherein original position can be the state of predetermine one when current played file starts to play.
can show that predetermine one often rotates 1 degree, need by playing progress rate regulate duration, by current operation angle C with
do product and just can draw the time coordinate that current operation angle is corresponding.
Refer to Fig. 8, in one embodiment, described S62 can also comprise following sub-step.
Step S626: the rotational angle of described predetermine one has at least one angular range, at least one angular range described is a corresponding scheduled duration respectively, judges the angular range residing for described current operation angle.
Step S628: playing progress rate is regulated the scheduled duration that described angular range is corresponding.
In the present embodiment, predetermine one can have at least one angular range, can for being an angular range at interval of a predetermined angle angle value.Such as being exemplified as, is an angular range at interval of 20 degree, then 0 degree to 19 degree can be the first angular range, and 20 degree to 39 degree can be the second angular range, and 40 degree to 59 degree can be angular extent, by that analogy, no longer enumerates as space is limited at this.
In the present embodiment, the corresponding scheduled duration of each angular range, such as be exemplified as, the scheduled duration that first angular range is corresponding is 10 seconds, the scheduled duration that second angular range is corresponding is 20 seconds, scheduled duration corresponding to angular extent is 30 seconds, by that analogy, no longer enumerates as space is limited.
Be appreciated that; the angle at interval is not limited to 20 degree; it can also be 10 degree, 30 degree or 40 degree etc.; the scheduled duration that each angular range is corresponding is not limited to aforementioned citing; it can also be arranged to other numerical value; those skilled in the art also may make other and change under the enlightenment of present techniques marrow, as long as but its function and effect and the application same or similar, all should be covered by the application's protection range.
In the present embodiment, by judging the angular range residing for current operation angle, just can obtain the scheduled duration needing to regulate, thus further playing progress rate can be regulated scheduled duration.Concrete is exemplified as, and suppose predetermine one current operation 30 degree, current operation angle is in the second angular range, and the scheduled duration that the second angular range is corresponding is 20 seconds, then in conjunction with the rotation direction of predetermine one, playing progress rate is regulated 20 seconds forward or backward.
In an execution mode of the application, can be: when described predetermine one rotates that playing progress rate is regulated the 3rd scheduled duration in described step S60.
In the present embodiment, the 3rd scheduled duration is the amplitude regulated playing progress rate, its time span can specified for any one, such as 1 second, 2 seconds, 3 seconds ... 15 seconds, 16 seconds ... 30 seconds etc., no longer enumerate as space is limited at this.Predetermine one occurs once to rotate, and in conjunction with rotation direction, playing progress rate is regulated the 3rd scheduled duration forward or backward.Wherein, from predetermined, turn to predetermine one rotation to terminate can think once to rotate.The scheme that present embodiment provides, only judges whether predetermine one rotates and regulate playing progress rate, does not consider the angle of rotating, so makes Media Stream control method for playing back more simple.
Refer to Fig. 9, in one embodiment, described step S60 can comprise following sub-step.
Step S63: the current operation angle and the current operation speed that calculate described predetermine one.
In the present embodiment, about the computational methods of current operation angle, the description carried out in the foregoing embodiment, no longer repeats to introduce at this as space is limited.
In the present embodiment, the angular speed that current operation speed can be rotated for predetermine one also can be the linear velocity of some parts on predetermine one.Described angular speed is the angle that turns within the unit interval of predetermine one or radian, its speed rotated after can indicating the corresponding control command of predetermine one.Concrete, be exemplified as: angular speed can be the quotient of the time of current pivot angle degree and cost, namely sets angular speed as ω, if current operation angle is α, if the time of cost is t, then can be angular velocity omega=α/t, now the unit of angular velocity omega be angle/second.Certainly, also according to existing formula, angular velocity omega can be converted into international unit radian per second further.Described linear velocity can be the ratio of any portion on predetermine one, the arc length turned in predetermine one rotation process and time used.
In the present embodiment, current operation angle can be the some moment in predetermine one rotation process, the angle that predetermine one rotates relative to initial position, also can for predetermine one be after completing and once rotating, from rotating initial position to the angle of rotating end position corotation and crossing.Current operation speed can be the velocity of rotation in the some moment in predetermine one rotation process, also can for predetermine one be after completing once rotation, calculate the average rotation speed of predetermine one in rotation process, using average rotation speed as current operation speed.
Step S64: regulate playing progress rate according to described current operation angle and current operation speed.
In the present embodiment, in predetermine one rotation process, a current operation angle and current operation speed can be calculated at interval of a set time, and regulates playing progress rate immediately; Also after predetermine one rotation terminates, current operation angle can be calculated, in the rotation process of predetermine one, calculates a current operation speed at interval of a set time.When regulating playing progress rate, in conjunction with the rotation direction of predetermine one, playing progress rate can be regulated forward or backward, specifically describes in aforementioned embodiments, no longer repeat at this.
Refer to Figure 10, in one embodiment, described step S64 also comprises following sub-step.
Step S641: described current operation angle is compared with threshold value.
In the present embodiment, threshold value can be an angle value of setting, when current operation angle is not more than threshold value, does not regulate playing progress rate, when current operation angle is greater than threshold value, regulates playing progress rate.In the process that video or audio file are play, user may misoperation cause predetermine one to rotate accidentally, by arranging threshold value, can to a certain degree avoid this misoperation to cause regulating playing progress rate.The value of threshold value can be 5 degree, 10 degree, 15 degree or 20 degree, and certainly, the value of threshold value can also have other value, will not enumerate as space is limited at this.
Step S643: described current operation angle is greater than threshold value, searches the coefficient corresponding with current operation speed in coefficient list.
In the present embodiment, coefficient list can be predefined data list, and in it, corresponding record has velocity of rotation and coefficient.A corresponding coefficient can be all set for each velocity of rotation, it is interval that several velocities of rotation also can be set, the interval corresponding coefficient of each velocity of rotation.Concrete, take velocity of rotation as angular speed be example, see the following form 1 citing.
Table 1 coefficient list
| Velocity of rotation scope | Coefficient |
| Current operation speed < 5 degree/second | 1 |
| 5 degree/second≤20 degree/second of current operation speed < | 1.5 |
| 20 degree/second≤current operation speed < 50 degree/second | 1.8 |
| 50 degree/second≤100 degree/second of current operation speed < | 2.2 |
| 100 degree/second≤200 degree/second of current operation speed < | 2.6 |
| 200 degree/second≤current operation speed | 3 |
Coefficient list can store in one file in the mode of list, also can store in tables of data in a database, can also directly be integrated in the code segment of program.
Step S645: the 4th scheduled duration and described coefficient are done product and draws adjustment duration.
In the present embodiment, the 4th scheduled duration can for the time span of specifying pre-set, such as 1 second, 2 seconds, 3 seconds ... 15 seconds, 16 seconds ... 30 seconds etc., no longer enumerate as space is limited at this.4th scheduled duration and coefficient are done product to calculate and adjust duration, realize to change according to the velocity of rotation speed of predetermine one the amplitude of accommodation of playing progress rate.So, realize when needs significantly adjust playing progress rate, can quick rotation predetermine one, now because velocity of rotation is very fast, the coefficient of its correspondence is comparatively large, the adjustment duration calculated can corresponding comparatively greatly, can realize regulating playing progress rate faster.When adjusting playing progress rate by a small margin, now can slow rotation predetermine one, now because velocity of rotation is comparatively slow, the coefficient of its correspondence is less, and the adjustment duration that technology draws is corresponding less, realizes having higher degree of regulation.
Step S647: playing progress rate is regulated adjustment duration.
In the present embodiment, in the process regulating playing progress rate, in conjunction with the rotation direction of predetermine one, playing progress rate can be regulated forward or backward.Concrete, be exemplified as: rotate if predetermine one is clockwise direction, direction then towards current played file end regulates playing progress rate, by current broadcasting time coordinate increase adjustment duration adjusted after time coordinate, if after current time coordinate increases adjustment duration, be more than or equal to the total length of current played file, then the time coordinate after regulating is the time coordinate at most end.If predetermine one is counterclockwise rotate, then regulate playing progress rate towards the direction that current played file starts, by current broadcasting time coordinate reduce adjustment duration adjusted after time coordinate, if after current time coordinate reduces to regulate duration, be less than or equal to zero, time coordinate after then regulating is zero, namely plays from the beginning of current played file.
Refer to Figure 11, in one embodiment, the rotational angle of described predetermine one has span, and the data in described span are a corresponding scheduled duration respectively, and described step S64 also comprises following sub-step.
Step S642: obtain the scheduled duration that described current operation angle is corresponding, obtains the coefficient corresponding with current operation speed.
In the present embodiment, predetermine one can have at least one angular range, can for being an angular range at interval of a predetermined angle angle value.Such as being exemplified as, is an angular range at interval of 20 degree, then 0 degree to 19 degree can be the first angular range, and 20 degree to 39 degree can be the second angular range, and 40 degree to 59 degree can be angular extent, by that analogy, no longer enumerates as space is limited at this.
In the present embodiment, the corresponding scheduled duration of each angular range, such as be exemplified as, the scheduled duration that first angular range is corresponding is 10 seconds, the scheduled duration that second angular range is corresponding is 20 seconds, scheduled duration corresponding to angular extent is 30 seconds, by that analogy, no longer enumerates as space is limited.
Be appreciated that; the angle at interval is not limited to 20 degree; it can also be 10 degree, 30 degree or 40 degree etc.; the scheduled duration that each angular range is corresponding is not limited to aforementioned citing; it can also be arranged to other numerical value; those skilled in the art also may make other and change under the enlightenment of present techniques marrow, as long as but its function and effect and the application same or similar, all should be covered by the application's protection range.
In the present embodiment, can by corresponding with scheduled duration for angular range storage in one file, also can, by the two corresponding stored tables of data in a database, can also directly be integrated in the code segment of program.
In the present embodiment, can coefficient list be pre-set, in coefficient list, record velocity of rotation and coefficient.A corresponding coefficient can be all set for each velocity of rotation, it is interval that some velocities of rotation also can be set, the interval corresponding coefficient of each velocity of rotation.Coefficient list can store in one file in the mode of list, also can store in tables of data in a database, can also directly be integrated in the code segment of program.
Step S644: described scheduled duration and described coefficient are done product and draws adjustment duration.
Step S647: playing progress rate is regulated adjustment duration.
In the present embodiment, scheduled duration can according to the rotational angle of predetermine one different and respective change, coefficient can according to the velocity of rotation of predetermine one different and respective change, realize the adjustment of playing progress rate more flexible.Be exemplified as, in twice operation, predetermine one have rotated identical rotational angle, but the velocity of rotation of predetermine one is different, when namely first time rotates, velocity of rotation is slower, when second time is rotated, velocity of rotation is very fast, and the adjustment duration that now this secondary operation obtains may be different.Predetermine one have rotated identical angle, then the corresponding scheduled duration of rotational angle is identical, but owing to there being different velocities of rotation in secondary operation, make coefficient possibility different, in first time rotation, the coefficient of the less correspondence of velocity of rotation may be less, in second time rotation, the coefficient of the larger correspondence of velocity of rotation may be comparatively large, so when calculating adjustment duration, rotating the adjustment duration drawn for the first time and may be less than the adjustment duration rotating for the second time and draw.In like manner, in twice operation, predetermine one has identical velocity of rotation, but rotational angle is different, and namely the rotational angle of first time rotation is less, and the rotational angle that second time is rotated is comparatively large, and the adjustment duration that now this secondary operation obtains also may be different.The velocity of rotation of predetermine one is identical, coefficient then in this secondary operation is identical, but because rotational angle in this secondary operation is different, in first time rotation, rotational angle is less, corresponding scheduled duration may be less, and in second time rotation, rotational angle is comparatively large, and corresponding scheduled duration may be larger, when so calculating adjustment duration, rotate the adjustment duration drawn for the first time and may be less than the adjustment duration rotating for the second time and draw.
In the present embodiment, can regulate playing progress rate in conjunction with the rotation direction of predetermine one, the concrete scheme regulating playing progress rate, is described in the foregoing embodiment, no longer repeats as space is limited at this.
