Digital video generally adopts the H264 standard that the analog signal of camera input is carried out digital coding, in order to reduce transmission and to preserve required bandwidth and the memory space of digital video signal, signal behind the coding is divided into I frame and P frame, the I frame is key frame, do not have the I frame, the follow-up P frame that receives can't be decoded and be reverted to analog signal and carry out video playback.The sequence of general digital video signal be an I frame heel with several P frame, the I frame has been preserved the complete information of piece image, the size behind the coding is bigger, the P frame is preserved with respect to the I frame, the information that image changes, so size is less.
When the terminal use need check a certain video, generally be to file an application to streaming media server, if streaming media server is being transmitted this passage video, then increase and be transmitted to this user, if streaming media server is not being transmitted this passage video, then streaming media server is submitted the preview video application to the camera passage of user's appointment.Terminal use end can dispose prediction scheme, and a prediction scheme comprises a plurality of camera passages, and the user can once watch a plurality of video playback by prediction scheme, and when prediction scheme time during to point, taking turn switches to next group prediction scheme and carries out the picture demonstration automatically.But, following problem can appear in this processing mode: when the prediction scheme time point then, the application of next the group video channel of preview of filing an application to streaming media server, because application constantly, just the I frame arrives, and may cause existing on the screen some seconds no video (and blank screen), simultaneously, also there is the network delay reason, causes on the screen some seconds no video.
[summary of the invention]
The technical problem to be solved in the present invention is to provide a kind of method of video taking turn seamless switching picture, and present technique reaches the seamless switching of picture by catching nearest I frame.
The present invention is achieved in that
A kind of method of video taking turn seamless switching picture comprises the steps:
Step 1, terminal use hold the configuration prediction scheme, dispose the demonstration time of described prediction scheme, and described prediction scheme comprises a plurality of video flowing passages; The prediction scheme of described prediction scheme for showing, the video flowing passage of a plurality of video flowing passages that comprise in the prediction scheme for showing;
Step 2, is set the prior notice time that prediction scheme is switched, when the described prior notice time then, client notification streams media server is ready;
Step 3, described streaming media server are preserved I frame nearest in the video that each camera is taken in the described prediction scheme and P frame subsequently;
Step 4, switching time, then described streaming media server at first sent described nearest I frame, sent the remaining P frame of this nearest I frame correspondence again, thus the seamless switching of picture when having realized the video taking turn.
Further, when the terminal use required streaming media server to close a certain video flowing, described streaming media server checked whether the passage of this video flowing correspondence is contained in the described prediction scheme, if then the passage of this video flowing correspondence is not done and closed.
Further, in the described step 2, the prior notice time is 15 seconds, switches preceding 15 seconds in prediction scheme, and client notification streams media server is ready.
The present invention has following advantage:
The present invention by prior notice time of switching in prediction scheme then, client prior notice streaming media server is ready, described streaming media server is preserved nearest I frame in the video that each camera is taken in the described prediction scheme; Switching time, then described streaming media server at first sent described nearest I frame, sent the remaining P frame of this nearest I frame correspondence again, thus the seamless switching of picture when having realized the video taking turn.
[description of drawings]
