Specific embodiment
Below in conjunction with attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete
Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Usually exist
The component of the embodiment of the present invention described and illustrated in attached drawing can be arranged and be designed with a variety of different configurations herein.Cause
This, is not intended to limit claimed invention to the detailed description of the embodiment of the present invention provided in the accompanying drawings below
Range, but it is merely representative of selected embodiment of the invention.Based on the embodiment of the present invention, those skilled in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
In the related technology, according to the demand of user, sometimes, user's expectation is on the same screen, while playing multiple views
Frequency picture.But the player on mobile terminal is merely able to play the same video in the same time, watches other views if necessary
If frequency, then needs to stop playing current video, the broadcasting of another video can be started.If being different player
Carry out video playing if, then due to system the problem of, on current screen, synchronization can only be by a player current
Video playing is carried out on screen, other have been started up, but to carry out the player of video playing on current screen, are then in
Halted state can not play video pictures and sound.
But in fact, user is to need to show that video pictures compare simultaneously sometimes, such as two production lines, or
Two monitored pictures of person can effectively compare two videos and draw only in the case where two videos are compared
Face.Otherwise, if can not show video pictures that needs play on current screen simultaneously, (some video can not be complete in other words
Played out on current screen), then it is difficult to effective opposite multiple videos and compares.
For another example, when song is rehearsed, in general, a personnel can only be responsible for the performance of a musical instrument, if it is desired to reach
It to the effect of (instrumental) ensemble, then has to be recorded to simultaneously in a video, but such mode needs personnel's set specified to one
Position.It is time-consuming and laborious, if personnel are not gathered to a specified position, but the video of each personnel is recorded respectively, then
When playing in the later period, the problem of due to player, it can not be completed at the same time broadcasting on mobile terminals, also can not just generate conjunction
The effect played.
In view of this, this application provides mobile terminal video playback methods, as shown in Figure 1, including the following steps:
S101 obtains the position selection instruction of each video to be played；
S102 judges whether region corresponding to each position selection instruction meets preset status requirement；If so, holding
Row step S103；
S103 on corresponding region, is played each simultaneously respectively according to the position selection instruction of each video to be played
Video to be played.
In step S101, video to be played is that user it is expected the video played on the display screen of mobile terminal.Certainly, it is
It can be realized Video Composition broadcasting, be necessarily required to select multiple videos to be played, and then accessed position selection instruction
It is also multiple, that is, each video to be played corresponds to a position selection instruction.
There are two types of the generation forms of position selection instruction, and one is users by touch screen, or passes through mobile cursor
Region one by one is irised out, each region (or multiple regions) generates a position selection instruction, that is, represents wait broadcast
Putting video will play out in the area video.Another form of position selection instruction is: system (on mobile terminal) is being shielded
The region of the multiple piecemeals of screen display is touched on curtain as shown in Fig. 2, system is divided good by this multiple regions, user by
Touch operation is carried out on these ready-portioned regions, and then generates corresponding electric signal, is with the selected region of informing system
Which.Both modes are compared, and the freedom degree of first way is stronger, but serious forgiveness is lower, and user is easy manual
When irising out region, follow-up process is caused mistake occur two region overlappings, or the region irised out is excessively scattered, and
Lead to the imperfect of broadcasting pictures.The second way, can to a certain extent constraint user operation, simplify system processing
Difficulty and calculation amount, but freedom degree is poor, for the video of certain Special Categories, the effect of display such as first way.
For first way, step S101, the position selection instruction for obtaining each video to be played includes:
Acquire the sliding touching instruction of user on the screen；
If sliding touching instruction forms a closed figures, the region which is irised out is selected as position
The corresponding region of instruction.
Step S102, needs to judge whether region corresponding to each position selection instruction meets preset status requirement,
It meets the requirements and can be understood as two aspects, one of them is, judges whether weigh between region corresponding to the selection instruction of position
It is folded.Description such as hereinbefore, if according to the generating mode of the first position selection instruction, corresponding to each position selection instruction
Region be it is irregular, then should first judge whether these regions are overlapped at this time, the video played is mutual to avoid occurring
The problem of interference.Specific judgment mode can be the edge function for first calculating region corresponding to each position selection instruction,
Judge whether these functions intersect later, that is, can determine whether these regions are overlapped.Life for second of position selection instruction
At mode, since system has pre-generated multiple regions as shown in Figure 2, the boundary in these regions is adjacent, but is being carried out
When regional choice, user may make a position selection instruction while correspond to multiple regions, at this point, in order to avoid occurring
Overlap problem first can carry out label to each region, later by comparing the mark of region corresponding to each position selection instruction
Number it may recognize that the phenomenon that whether overlapping having occurred between region corresponding to the selection instruction of position.It is specific as shown in table 1,
Table 1
| Number | Video to be played | Position selection instruction | Region |
| 1 | Video 1 | Instruct A | No. 1 |
| 2 | Video 2 | Instruct B | No. 2, No. 3 |
| 3 | Video 3 | Instruct C | No. 3, No. 4 |
| 4 | Video 4 | Instruct D | No. 5 |
The region seen instruction B and instruct C that can be apparent from table 1 is that have overlapped part, at this time should
Stop current process, or re-execute the steps S101.
When step S102 is judged as NO, that is, there is no phase mutual respect between region corresponding to the selection instruction of position
When folded part, available table table 2 as shown in Table 2
| Number | Video to be played | Position selection instruction | Region |
| 1 | Video 1 | Instruct A | No. 1 |
| 2 | Video 2 | Instruct B | No. 2 |
| 3 | Video 3 | Instruct C | No. 4 |
| 4 | Video 4 | Instruct D | No. 5 |
System can carry out the broadcasting of video according to as shown in the table in table 2 on corresponding position.Table 2 is corresponded to, is
System can play video 1 on No. 1 region, and video 2 is played on No. 2 regions, video 3 be played on No. 4 regions, No. 5 positions
It sets and plays video 4, so as to complete the broadcasting of video.When needing to illustrate, video playing be include two parts content,
A part is vision signal (image), and a part is audio signal, this two parts can be exported simultaneously with two parts.
When carrying out music class Video Composition, must occur that audio signal, vision signal can according to
The needs at family selectively play out.It should be noted that region corresponding to the selection instruction of position only defines video
The output position of signal, but there is no the output position for constraining audio signal, audio signal can according to need, by leaning near position
The sound equipment of areas adjacent corresponding to selection instruction carries out the output of audio signal.
Judge whether region corresponding to each position selection instruction meets preset status requirement, meeting the requirements can manage
Solution for two aspect, wherein second is that, judge whether the region of video actual play has exceeded the maximum magnitude of screen, that is,
Whether the actual play region of video covers the position other than screen.
Specifically, zoom factor can be carried in the selection instruction of position, be also possible to user by it is independent instruct to
System assigns zoom factor, and system is getting zoom factor, needs to calculate the actual play region of video later, and then check
Whether the actual play region has exceeded the range of screen.It can also be that user after video is set play position, and drags
It moves the play position to be adjusted, actual play region is finally made to have exceeded the boundary of screen, this equally will affect video
Normal play.
Further, in mobile terminal video playback method provided herein, before step S103, that is, step is played
Before further include following steps:
Judge whether the broadcasting direction of video to be played is consistent with reference direction；
If it is not, the broadcasting direction of video to be played is then rotated, until consistent with reference direction.
Video, if playing angle difference, is difficult to play enough paired observation effects when playing out, because
This, execute play step before, should the broadcasting direction to video be adjusted.In fact, playing direction is to receive recording
What direction was influenced, therefore, when carrying out video acquisition or video acquisition, preferably while getting the recording of video
Direction, the recording direction can be personnel's input of recorded video, be also possible to system automatic identification.It needs to illustrate
It is that when needing system automatic identification, can be through image capturing software and carry out the extraction of feature picture, Zhi Hougen
The broadcasting direction of the video is judged according to the upright direction of personage.It is of course also possible to be user after watching video, manually into
Row plays the definition in direction.
It, can be targetedly to broadcasting direction and standard side after judging whether broadcasting direction and reference direction are consistent
It is had rotated to inconsistent video pictures.Specifically, being rotated (alternatively to each frame image of video
It is rotated to direction is played with the inconsistent image frame of reference direction).
Further, before step S101, that is, it further includes as follows for obtaining before the position selection instruction of each video to be played
Step:
S11 obtains layout and establishes instruction；
S12 is searched in the database, location layout mode corresponding with layout foundation instruction；
S13, according to location layout mode, display position selects information on the screen.
In step S11, system needs to receive layout foundation instruction provided by user, and layout, which is established corresponding to instruction, is
The generation method of second of position selection instruction.Before executing step S11, location layout mode and layout can be pre-established
The incidence relation of instruction is established, it is one-to-one relationship that location layout mode and layout, which establish instruction,.And every kind of position cloth
Office's mode is different, specifically, containing two attribute in location layout mode, the first attribute is the position in region
(position of characteristic point), the second attribute are the sizes (after connecting characteristic point, the size in the region irised out) in region.Such as figure
Shown in 3A and Fig. 3 B, provide two kinds of location layout modes, can intuitively find out Fig. 3 A by entire screen divide in order to 2*2 this
Four regions, Fig. 3 B divide entire screen for this nine regions 3*3.Certainly, there are also other for the mode of specific region division
Type is only indicated using two kinds of characteristic modes herein.
As shown in table 3,
Table 3
| Number | Layout establishes instruction | Location layout mode |
| 1 | Instruction 1 | Mode A |
| 2 | Instruction 2 | Mode B |
| 3 | Instruction 3 | Mode C |
| 4 | Instruction 4 | Mode D |
Layout is established instruction and is corresponded with location layout mode, is established and is instructed according to layout accessed by step S11
Location layout mode can directly be found, in turn, can according to location layout mode on the screen display position select information.
Position selection information as shown in Figure 3A can be to be shown in each area, and shown content is not phase in each region
With.
To assist user to carry out the selection in region.
Further, mobile terminal video playback method provided herein, further includes:
Video amplifier multiple is obtained from the selection instruction of position；
Whether actual play area is judged with location layout mode, the area of ready-portioned play area is consistent,
Actual play area is calculated according to the former broadcasting area and video amplifier multiple of video to be played；
If being consistent, thens follow the steps respectively while playing each video to be played.
It is, user, which can according to need to system, assigns the amplification that specified video carries out how many multiples.Wherein,
Whether actual play area is judged with location layout mode, and the area of ready-portioned play area is consistent, and refers to, judges
Whether actual play area is adapted with location layout mode, and can location layout mode kind provide the area of such area in other words
Domain plays out.As shown in Figure 4 A, which is divided into this nine regions 3*3, and is respectively toward to 9 regions and is marked
Number, respectively No. 1-9.When video amplifier multiple is 1, actual play area is that the former area that plays (is defaulted as a region
Area), at this point, any one region of the screen can carry the playing task of the video.When playing multiple is 2
It waits (actual play area=2*2=4), also just needs 2*2, the broadcasting of the video is completed in four adjacent regions jointly, such as
1,2,4,5 this four regions being capable of function completion video playing.When playing multiple is 4, then 4*4,16 regions are needed
Playing task is completed jointly, at this point, just illustrate actual play area and location layout mode kind, ready-portioned broadcast area
The area in domain is not consistent and (has exceeded maximum area), should stop process at this time.
When be judged as be consistent when, then can execute step S103.
Further, as shown in Figure 4 A, screen is divided into multiple play area, at this point, video amplifier multiple should
Less than or equal to the evolution of the total amount of play area, to guarantee that video can be played normally.As shown in Figure 4 A, video amplifier
Multiple square be equal to actual play area, it may be assumed that
If screen is divided into multiple play area by location layout mode, and multiple play area are arranged according to square matrix formula,
Then judge actual play area whether in location layout mode, the area of ready-portioned play area has been consistent includes:
Video amplifier multiple is obtained from the selection instruction of position；
Judge whether video amplifier multiple is less than or equal to the evolution of play area total amount, if so, thening follow the steps simultaneously
Play corresponding video to be played.
As shown in Figure 4 B, in Figure 4 A by amplified video, after 4 regions in the upper left corner play, become in Fig. 4 B,
No. 0 region, i.e., No. 0 region in figure 4b amplify after video playing.As shown in Figure 4 C, amplified video is being schemed
In 4A, after 4 regions in the lower right corner play, become in Fig. 4 C, No. 4 regions, i.e., after No. 4 regions in figure 4b amplify
Video playing.
Specifically, can be instructed according to the special efficacy got, when carrying out video playing to vision signal or audio
Signal performs corresponding processing, that is, step exports the vision signal of each video to be played and audio signal includes:
If getting the instruction of the first special efficacy, when exporting the vision signal of video to be played, instructed according to the first special efficacy
Vision signal is adjusted；
If getting the instruction of the second special efficacy, when exporting the audio signal of video to be played, instructed according to the second special efficacy
Audio signal is adjusted.
