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 the method flow diagram that transition plays between a kind of video according to an exemplary embodiment, such as Fig. 1 institutes
Show, the method that transition plays between the video, comprise the following steps S11-S13：
In step s 11, judge to whether there is video to be played in video play lists；
In step s 12, in the case of it video to be played be present in the video play lists, regarded what is played
The video content of frequency and next video to be played carries out transition processing；
In step s 13, the video content that progress transition processing is crossed is replaced into former video content.
In one embodiment, people usually can continuously watch multiple video contents, and either viewing has been downloaded offline
Video, or viewing Online Video, adjacent two videos, sometimes can be adjacent two because of this when transition plays
The audio-video frequency content difference of video is excessive, so as to cause user to produce lofty, unexpected viewing experience.The present embodiment
In technical scheme can the above-mentioned technical problem of adequate solution.
Judge to whether there is video to be played in video play lists.Further, when in the video play lists
When video is offline video, judge whether the quantity of the video to be played in the video play lists is more than positive integer one.When this
When video in video play lists is Online Video, judge that the video played whether there is associated video.
In the case of it video to be played be present in the video play lists, by the video played and next wait to broadcast
The video content for putting video carries out transition processing.Further, the last n frames of the video played and next are extracted
The preceding m frames of video to be played；The last n two field pictures of the video played are carried out at the gradual change of transparency from high to low
Reason；The preceding m two field pictures of next video to be played are carried out into the gradual change of transparency from low to high to handle.
The video content that progress transition processing is crossed is replaced into former video content.Further, it will pass through what gradual change treated
The last n two field pictures of the video played replace the last n frames of the former video played.Under being treated by gradual change
The preceding m two field pictures of one video to be played replace the preceding m two field pictures of former next video to be played.
Technical scheme in the present embodiment can effectively avoid lofty audio-video frequency content when transition plays between video
Change, so as to improve viewing experience of the user when continuously watching multiple videos.
In one embodiment, as shown in Fig. 2 step S11 comprises the following steps S21-S22：
In the step s 21, when the video in the video play lists is offline video, the video playback row are judged
Whether the quantity of the video to be played in table is more than positive integer one；
In step S22, when the video in the video play lists is Online Video, played described in judgement
Video whether there is associated video.
In one embodiment, when the video in the video play lists is offline video, often viewing is continuous by people
The variety show of acute or continuous more phases, judges whether the quantity of the video to be played in the video play lists is more than positive integer
One.The situation of Online Video needs to judge that the video played whether there is associated video, and associated video refers to this
The video that the video playback of broadcasting just plays at once after terminating.When meeting the above situation, the technical side in the application is enabled
Case, and for the resource for the system of saving, only the video played and next video to be played are handled accordingly.
In one embodiment, as shown in figure 3, step S12 comprises the following steps S31-S33：
In step S31, the last n frames of video and the preceding m of next video to be played played is extracted
Frame；

Processing；
In step S33, the preceding m two field pictures of next video to be played are subjected to the gradual change of transparency from low to high
Processing.
In one embodiment, after the decoding and decompression of video, video that this is being played is extracted most
The preceding m frames of n frames and next video to be played afterwards, wherein, the conclusion by multiple scientific validation is when m and n is 30
Wait, preferable technique effect and viewing experience can be obtained.The last n two field pictures of the video played are subjected to transparency
Gradual change processing from high to low, and the preceding m two field pictures of next video to be played are subjected to the gradual change of transparency from low to high
Processing.It is above-mentioned in addition to the gradual change processing of transparency, alternative technical scheme includes gradual change processing and the Marseille of fuzziness
Gram gradual change processing.
In one embodiment, as shown in figure 4, step S13 comprises the following steps S41-S42：
In step S41, the last n two field pictures of the video played treated by gradual change are replaced into original and broadcast
The last n frames for the video put；
In step S42, the preceding m two field pictures of the next video to be played treated by gradual change are replaced former next
The preceding m two field pictures of video to be played.
In one embodiment, the last n two field pictures of the video played treated by gradual change are being replaced into original just
In the last n frames of the video of broadcasting, the preceding m two field pictures of the next video to be played treated by gradual change are replaced former next
The preceding m two field pictures of individual video to be played, after the coding of video and encapsulation, by the image by gradual change processing with former video
Coded format is encapsulated into former video.Meanwhile the image being replaced is discarded.
In one embodiment, as shown in figure 5, also comprising the following steps S51-S52：
In step s 51, to corresponding to the last n two field pictures of the video played audio-frequency information carry out volume by
Small gradual change processing is arrived greatly；
In step S52, to corresponding to the preceding m two field pictures of next video to be played audio-frequency information carry out volume by
It is small to be handled to big gradual change.
In one embodiment, in order to reach the viewing effect that transition plays between more preferable video, while by audio-frequency information
Also gradual change processing is carried out, it is corresponding to the last n two field pictures of the video played after the decoding and decompression of video
Audio-frequency information carry out the descending gradual change processing of volume, and to corresponding to the preceding m two field pictures of next video to be played
Audio-frequency information carries out the ascending gradual change processing of volume.After coding and encapsulation by audio, by by gradual change processing
Audio-frequency information is encapsulated into former video with former audio coding formats.
In one embodiment, Fig. 6 is the device of transition broadcasting between a kind of video according to an exemplary embodiment
