The schematic flow sheet of a kind of video-splicing method that Fig. 1 provides for the embodiment of the present invention;
The structural representation of a kind of video-splicing device that Fig. 2 provides for the embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The schematic flow sheet of a kind of video-splicing method that Fig. 1 provides for the embodiment of the present invention, can comprise:
S101: obtain at least two video-frequency bands to be spliced;
S102: the regulating command receiving user's input;
Described regulating command is for setting splicing playing duration or the splicing broadcasting speed of each video-frequency band to be spliced of acquisition;
S103: according to splicing playing duration or the splicing broadcasting speed of the described video-frequency band of described setting, described video-frequency band is regulated;
S104: the described video-frequency band after described adjustment is spliced into a video, to make in described spliced video, described video-frequency band according to described setting splicing playing duration or splicing broadcasting speed play.
Exemplary, suppose that the video-frequency band to be spliced obtained is video-frequency band A and video-frequency band B, wherein, the former broadcasting speed of video-frequency band A is v1 frame/second, and duration is the former broadcasting speed of t1, video-frequency band B is v2 frame/second, and duration is t2;
In actual applications, the splicing playing duration that user can input each video-frequency band to be spliced sets splicing reproduction time, and the splicing broadcasting speed that also can input each video-frequency band to be spliced sets splicing broadcasting speed.
When user inputs the splicing playing duration of each video-frequency band to be spliced, the splicing playing duration of the video-frequency band A of the user's input supposing to receive is the splicing playing duration of t3, video-frequency band B is t4.
Can judge that whether former playing duration t1 is equal with the splicing playing duration t3 of acquisition for video-frequency band A;
If t3 equals t1, then without the need to adjusting video-frequency band A.
If t3 is not equal to t1, then according to the splicing playing duration of the video frame number of video-frequency band A and video-frequency band A, the broadcasting speed of video-frequency band A in spliced video can be calculated; The broadcasting speed of video-frequency band A is adjusted to the broadcasting speed in spliced video calculated.
Obtain the video frame number m of video-frequency band A, be t3 according to the video frame number m of video-frequency band A and splicing playing duration, calculate the broadcasting speed=m/t3 of video-frequency band A in spliced video (frame/second), the broadcasting speed of video-frequency band A is adjusted to m/t3 (frame/second), such as, the video frame number of video-frequency band A is 200, splicing reproduction time is 8 seconds, then broadcasting speed=200 frame/8 of video-frequency band A in spliced video second=25 frames/second, the broadcasting speed of video-frequency band A is adjusted to 25 frames/second.
If t3 is not equal to t1, according to the former playing duration of video-frequency band A and the former broadcasting speed splicing playing duration and video-frequency band A, the broadcasting speed of video-frequency band A in spliced video can also be calculated; The broadcasting speed of video-frequency band A is adjusted to the broadcasting speed in spliced video calculated.
Concrete, when not changing the video frame number of video-frequency band A,
The splicing broadcasting speed of the splicing playing duration * video-frequency band A of the former broadcasting speed=video-frequency band A of the former playing duration * video-frequency band A of the video frame number=video-frequency band A of video-frequency band A;
Splicing playing duration=the t1*v1/t3 (frame/second) of the former broadcasting speed/video-frequency band A of the former playing duration * video-frequency band A of the splicing broadcasting speed=video-frequency band A of video-frequency band A, namely in the changeless situation of video frame number of video, the playing duration of video and the inversely proportional relation of broadcasting speed, playing duration is longer, broadcasting speed is slower, playing duration is shorter, broadcasting speed is faster, such as, the former playing duration of video-frequency band A is 100 seconds, former broadcasting speed is 10 frames/second, and splicing playing duration is 200 seconds, then splicing broadcasting speed is 5 frames/second.
If t3 is not equal to t1, when t3 is greater than t1, under the prerequisite of broadcasting speed not changing video-frequency band A, frame of video can also be carried out to video-frequency band A and insert process, with the splicing playing duration making the playing duration of video-frequency band A be adjusted to setting.
Concrete, suppose t3=100 second, t1=50 second, the former frame of video of video-frequency band A is respectively P1, P2 ... P50 amounts to 50 frames, frame of video is carried out to video-frequency band A and inserts process, with the splicing playing duration making the playing duration of video-frequency band A be adjusted to setting, in actual applications, a frame of video can be inserted and insert a frame of video before the first frame of video P1 of video-frequency band A in adjacent two frame of video of video-frequency band A, the frame of video of video-frequency band A being adjusted to and carrying out the frame of video after inserting frame of video process; In order to ensure seamlessly transitting of picture, the pixel value of a certain pixel of the frame of video of insertion can be the mean value of the pixel value of adjacent two these pixels of frame of video; In actual applications, can also insert the frame of video identical with this frame of video before or after a certain frame of video of video-frequency band A, such as, the frame of video inserting frame of video backsight frequency range A is respectively P1, P1, P2, P2 ... P50, P50 amount to 100 frames.
When t3 is less than t1, under the prerequisite of broadcasting speed not changing video-frequency band A, frame of video pump-and-treat system can also be carried out to video-frequency band A, with the splicing playing duration making the playing duration of video-frequency band A be adjusted to setting.
Concrete, suppose t3=25 second, t1=50 second, the former frame of video of video-frequency band A is respectively P1, P2 ... P50 amounts to 50 frames, frame of video pump-and-treat system is carried out to video-frequency band A, with the splicing playing duration making the playing duration of video-frequency band A be adjusted to setting, in actual applications, all odd video frames of video-frequency band A can be extracted out or the extraction of all even video frames, the frame of video of video-frequency band A is adjusted to and carry out the frame of video after extracting frame of video process out; Such as, the frame of video of extracting all odd video frame backsight frequency range A out is respectively P2, P4, P6 ... P50 amounts to 25 frames, and the frame of video of extracting all even video frame backsight frequency range A out is respectively P1, P3, P5 ... P49 amounts to 25 frames.
It should be noted that, the present invention does not limit the insertion of frame of video and the concrete methods of realizing of extraction, and any mode in the cards all can be applied in the present invention.
When user inputs the splicing broadcasting speed of each video-frequency band to be spliced, according to splicing playing duration or the splicing broadcasting speed of the described video-frequency band of described setting, described video-frequency band is regulated, can judge that whether the former broadcasting speed of this video-frequency band is identical with the splicing broadcasting speed of the video-frequency band of described setting; If not, the splicing broadcasting speed of this video-frequency band is adjusted to the splicing broadcasting speed of described setting.
Exemplary, suppose that the splicing broadcasting speed of the video-frequency band A of the user's input received is v3 frame/second, the splicing broadcasting speed of video-frequency band B is v4 frame/second.
Can judge that whether former broadcasting speed v1 is equal with the splicing broadcasting speed v3 of acquisition for video-frequency band A;
If v3 equals v1, then without the need to adjusting video-frequency band A.
If v3 is not equal to v1, then the splicing broadcasting speed of video-frequency band A is adjusted to v3, such as, the former broadcasting speed v1 of video-frequency band A is 20 frames/second, the splicing broadcasting speed v3 receiving the video-frequency band A of user's input is 25 frames/second, then the splicing broadcasting speed of video-frequency band A is directly adjusted to 25 frames/second.
Adjustment for video-frequency band B can with reference to the above-mentioned adjustment for video-frequency band A, and the present invention no longer repeats the adjustment for video-frequency band B.
It should be noted that, to be above-mentionedly described for video-frequency band A and video-frequency band B, be only an instantiation of the present invention, do not form limitation of the invention.
