Embodiment
The preferred embodiments of the present invention are illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein preferred real
Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
Fig. 1 is a kind of method flow diagram of intelligence broadcasting video according to an exemplary embodiment, as shown in figure 1,
This intelligently plays the method for video, comprises the following steps S11-S13：
In step s 11, former video is subjected to default processing, generates key frame images set；
In step s 12, while former video is played in big window, the key frame figure is synchronously shown in wicket
Image set closes；
In step s 13, the playing status synchronism of the former video in the big window is implemented in the institute in wicket
State key frame images set.
In one embodiment, user is when video is edited, it is often necessary to editing video.In traditional editing mode
In, it is to need substantial amounts of troublesome operation that purpose frame of video is accurately determined during editing video.In general editing is grasped
During work, the multiple adjustment of user near a time point again and again is generally required, could accurately orient mesh
Mark frame of video.Technical scheme in the present embodiment can be appropriate processing above mentioned problem.
Former video is subjected to default processing, generates key frame images set.Further, at interval of default first frame
Number, extracts video frame images in former video.The video frame images extracted are zoomed in and out into processing.By regarding by scaling processing
The image collection that the generation of frequency two field picture can be shown.The image collection that confirming this can show is key frame images set.
While former video is played in big window, the key frame images set is synchronously shown in wicket.Further
, obtain the broadcasting speed that the former video is played in big window.According to the broadcasting of default first frame number and the former video
Speed, calculate the broadcasting speed of the key frame images set.Confirm that the broadcasting speed of the key frame images set is broadcast for first
Put speed.While former video is played in big window, the key is synchronously played with first broadcasting speed in wicket
Two field picture set.
The playing status synchronism of former video in the big window is implemented in the key frame images set in wicket.
Further, the broadcast state of the former video in the big window is obtained in real time.By the broadcast state of the former video by adaptation
After reason, the displaying instruction of the key frame images set is generated.Instructed according to the displaying of the key frame images set small to be illustrated in
The key frame images set in window.
Technical scheme in the present embodiment can be fast accurately determine the accurate location of purpose frame of video, so as to be lifted
Usage experience of the user in editing video.
In one embodiment, as shown in Fig. 2 step S11 comprises the following steps S21-S24：
In the step s 21, at interval of default first frame number, video frame images in former video are extracted；
In step S22, the video frame images extracted are zoomed in and out into processing；
In step S23, the image collection that can be shown will be generated by the video frame images for scaling processing；
In step s 24, the image collection that can be shown described in confirmation is key frame images set.
In one embodiment, since the first frame video image of former video, at interval of default first frame number, such as
6 frames, extract video frame images in former video.Those video frame images extracted are played in wicket, the reduction figure passed through
The memory space of the required occupancy of those video frame images extracted is reduced as the mode of pixel, is seen not influenceing user
While seeing effect, the data volume of key frame images set is effectively reduced.Video frame images by scaling processing are given birth to
Into the image collection that can be shown, the image collection sorts to show image with default image in preset speed, and this is default
Image sequence is the sequencing of video frame images in former video and determined.The image collection that confirming this can show is
Key frame images set, in case synchronously being shown in wicket.
In one embodiment, as shown in figure 3, step S12 comprises the following steps S31-S34：
In step S31, the broadcasting speed that the former video is played in big window is obtained；
In step s 32, according to default first frame number and the broadcasting speed of the former video, the pass is calculated
The broadcasting speed of key two field picture set；
In step S33, the broadcasting speed for confirming the key frame images set is the first broadcasting speed；
In step S34, while former video is played in big window, come in wicket with first broadcasting speed
It is synchronous to play the key frame images set.
In one embodiment, obtain and the broadcasting speed of the former video played in big window, according to this default
The broadcasting speed of one frame number and the former video, calculates the broadcasting speed of the key frame images set, confirms the key frame images
The broadcasting speed of set is the first broadcasting speed, while former video is played in big window, first is broadcast with this in wicket
Speed is put synchronously to play the key frame images set, is just regarded by the playing progress rate of the such scheme key frame images with original
The playing progress rate of frequency is synchronous.For example, the broadcasting speed of former video is 30 frames/second, default first frame number is 6 frames, by original
The broadcasting speed of video is 30 frames/second divided by default first frame number is 6 frames, can be calculated the first of key frame images set
Broadcasting speed is 5 frames/second, can meet what is played with former audio video synchronization with the speed of 5 frames/second to play key frame images set
Technical purpose.
In one embodiment, as shown in figure 4, step S13 comprises the following steps S41-S43：
In step S41, the broadcast state of the former video in the big window is obtained in real time；
In step S42, by the broadcast state of the former video after adaptation processing, the key frame images collection is generated
The displaying instruction of conjunction；
In step S43, the pass in wicket is illustrated according to the displaying instruction of the key frame images set
Key two field picture set.
In one embodiment, the broadcast state of former video includes pause, F.F., rewind, progress redirect etc..By the original
The broadcast state of video generates the displaying instruction of the key frame images set after adaptation processing.According to the key frame images
The displaying of set is instructed to be illustrated in the key frame images set in wicket.For example, the broadcast state of former video is 3 speeds
F.F., then the displaying instruction as 3 speed F.F.s of key frame images set, the key of the synchronous displaying by wicket
Two field picture set is with the former 3 speed F.F.s for showing speed.For another example the broadcast state of former video is jump to aggregate scheduling 85%
Place, then the displaying instruction of key frame images set is key at the 85% of the displaying progress for jumping to key frame images set
The displaying image of two field picture set is the key frame images at the 85% of displaying progress immediately.
