In order to solve the above technical problems, the embodiment of the invention provides a kind of video cache processing method, the method can be with Server side is applied to, Fig. 1 shows the schematic flow sheet of video cache processing method according to an embodiment of the invention.Ginseng See Fig. 1, the method at least includes step S102 to step S108.
Step S102, receives the video playback request from client, according to the video mark included in video playback request Knowledge finds video content corresponding with video labeling.
In the step, client can be arbitrary video player, such as " 360 video display are complete works of ", " youku.com ", " iqiyi.com Video " etc., or any browser, such as " 360 secure browser ", " QQ browsers ", " Google's browser ".The present invention Embodiment is not specifically limited to client, as long as belong to the embodiment of the present invention with the client for playing video capability Protection domain.
In this step, video labeling can be video name, video address or keyword related to video etc..Example Such as, if video labeling is video address, after client receives the URL addresses of a certain video of user input, will can be somebody's turn to do URL addresses are sent to server, so as to by the server by utilizing corresponding video content of URL address searches.If again for example, video Video name is designated, after client receives video name " Opening Ceremony of the Games in 2016 " of user input, this is regarded Frequency title " Opening Ceremony of the Games in 2016 " is sent to server, so as to by whois lookup to " Opening Ceremony of the Games in 2016 " Video content.
Step S104, transcoding successively is carried out to the video content for finding according to video time line, and generation client can The Video Quality Metric content of identification is simultaneously cached, and the Video Quality Metric content that will have been cached is sent to client successively by transcoding order With by client terminal playing video.
In this step, video time line is the time sequencing of video playback.Server is suitable according to the time of video playback The video content that ordered pair finds carries out transcoding successively, and the Video Quality Metric content generated after transcoding can be recognized by client.Example Such as, the video that whois lookup is arrived is WMV forms, and currently used " 360 video display the are complete works of " player of user cannot play WMV The video of form.Now, in order that " 360 video display are complete works of " player can smoothly play the video, server is in by video Hold and send to before " 360 video display are complete works of ", can be first MP4 or AVI format video by the video code conversion of WMV forms, so that can So that " 360 video display are complete works of " player is capable of identify that and plays the video.
Step S106, when the video jump request of the point of the random time from client is received, from regarding for having cached The video time point of random time point hit is determined in the video time line of frequency converted contents.
In this step, the video jump request of the random time point of client can be triggered by user, when user will Current video playing progress rate in video progress bar is dragged to when sometime putting, when can trigger user end to server and sending this Between put video jump request.For example, current video has been played 30 minutes, now, corresponding time point is on video progress bar 30:00, if user wants viewing from 40:During the video content of 00 beginning, then video progress bar can be dragged to 40:00 when Between put position at so that trigger user end to server send 40:The video jump request at 00 moment, when server receives this During video jump request, 40 are determined from the video time line of buffered Video Quality Metric content:Video at 00 moment Time point.
Step S108, transfers in the partial video conversion in the Video Quality Metric content for having cached with random time point as starting point Hold and send to client, with by client by currently playing video jump to the corresponding video location of random time point after Continued broadcasting is put.
In the embodiment of the present invention, when user drags to currently playing video progress bar, if the time point of dragging Time point in the video time line of the Video Quality Metric content that hit has been cached, then server can directly by with the time point The partial video converted contents of starting point are sent to client, with by client at time point position continue broadcasting and regard Frequently, save client waiting for server carries out the time of real-time transcoding to the video content for needing redirect broadcasting, so as to save The stand-by period of user, improve the operating experience of user.
Further, the Video Quality Metric content caching after transcoding can also effectively be mitigated into client in server side Caching burden, saved the spatial cache of client.
Step S104 is seen above, in one embodiment of the invention, the Video Quality Metric content that client is capable of identify that will be generated And after caching, the content of at least one of can also be cached, such as the key frame of Video Quality Metric content, key frame exist The start time point and deadline of corresponding time point and Video Quality Metric content on video time line on video time line Point.Wherein, in the key frame of buffered video converted contents, can be with key frame more visible in selecting video converted contents Hold.
Step S106 and foregoing embodiments are seen above, in one embodiment of the invention, can also be come as follows Determine the video time point of random time point hit.
If by judging to find, random time point is located at starting of the Video Quality Metric content for having cached on video time line Between time point and stop time point, then when can determine the video of the Video Quality Metric content that the hit of random time point has been cached Video time point in top-stitching.
If by judging to find, random time point is not located at the Video Quality Metric content for having cached on video time line Start time point and stop time point between, then the random time point and the miss Video Quality Metric for having cached can be determined Video time point in the video time line of content.
For example, random time point is 20:00, the time span of the Video Quality Metric content for having cached is 30 seconds 28 minutes, and The start time point of the Video Quality Metric content for having cached is 0:00th, stop time point is 28:30, then determine random time point 20:00 hit caching, and the video time point of hit is 20:00.Again for example, random time point is 29:00, the video for having cached The start time point of converted contents is 0:00th, stop time point is 28:30, then determine random time point 29:00 does not hit Caching.
Step S108 and foregoing embodiments are seen above, in one embodiment of the invention, transfers what is cached in server Partial video converted contents in Video Quality Metric content with random time point as starting point, and the partial video transferred is changed interior Hold and send during to client, server can first find the corresponding pass of random time point from the Video Quality Metric content for having cached Key frame, then transfers the partial video converted contents with the corresponding key frame of random time point as starting point, and send to client again End, so that currently playing video content to be jumped to continue at the corresponding key frame position of random time point by client playing Video.
In order to clearly embody the scheme of the embodiment of the present invention, now with the embodiment under a concrete scene to this hair It is bright to be introduced.In this embodiment, client is " 360 video display are complete works of ", and the video content of broadcasting is for " Olympic Games in 2016 are opened Curtain formula ".
When input video title " Opening Ceremony of the Games in 2016 " in input frame of the user " 360 video display are complete works of ", " 360 video display are complete works of " corresponding server receives the video playback request of its transmission, and searches " the opening of the Olympics in 2016 The video content of formula ".Then, server is carried out according to video time line to " Opening Ceremony of the Games in the 2016 " video for finding Transcoding successively, the Video Quality Metric content of " Opening Ceremony of the Games in 2016 " that generation " 360 video display are complete works of " can be recognized simultaneously is cached, And then the Video Quality Metric content that will have been cached is sent to " 360 video display are complete works of " successively by transcoding order, " 360 video display are complete works of " connects " Opening Ceremony of the Games in the 2016 " video after transcoding is received, and is played out.
If current video has been played 30 minutes, the progress bar of video is in 30:At 00 position, now, user will be current Time on the progress bar of " Opening Ceremony of the Games in the 2016 " video played is dragged to 40:At 00 position, so as to trigger " 360 video display are complete works of " sends 40 to server:The video jump request at 00 time point.When server is received from " 360 video display The 40 of complete works ":After the video jump request at 00 time point, can first " the opening of the Olympics in 2016 from after the transcoding for having cached Determine 40 in the video time line of formula ":The video time point that 00 time point was hit.If " 2016 after the transcoding for having cached The start time point of Opening Ceremony of the Games " is 0:00th, stop time point is 50:00.So, server can transfer what is cached With 40 in " Opening Ceremony of the Games in 2016 " video after transcoding:00 for the partial video of starting point and transmission is to " 360 video display are big Entirely ".When " 360 video display are complete works of " is received with 40:00 for after starting point " Opening Ceremony of the Games in 2016 " video, meeting automatically ought " Opening Ceremony of the Games in the 2016 " video of preceding broadcasting is from 30:00 time point jumps to 40 at position:At 00 time point position, And with 40:00 time was that starting point continues to play video.
The embodiment of the present invention additionally provides another video cache processing method, and the method can apply to server side, Fig. 2 shows the schematic flow sheet of video cache processing method in accordance with another embodiment of the present invention.Referring to Fig. 2, the method At least include step S202 to step S216.
Step S202, receives the video playback request from client, according to the video mark included in video playback request Knowledge finds video content corresponding with video labeling.
In this step, the embodiment of the present invention is not specifically limited to client, as long as with video playback capability Client (such as browser, video player) belongs to the protection domain of the embodiment of the present invention.
Step S204, transcoding successively is carried out to the video content for finding according to video time line, and generation client can The Video Quality Metric content of identification is simultaneously cached, the Video Quality Metric content that will have been cached by transcoding order send successively to client with by Client terminal playing video.
In the step, the Video Quality Metric content that server will have been cached sends during to client successively, will first can delay The Video Quality Metric content deposited is packaged into the form of chunk, is then sent successively to client in the way of chunk bags again.
In the step, after the Video Quality Metric content caching that the client of generation is capable of identify that, can also by it is following extremely One of few content is cached in the form of a list, and such as the key frame of Video Quality Metric content, key frame are on video time line The start time point and stop time point of corresponding time point and Video Quality Metric content on video time line etc..Wherein, exist During the key frame of buffered video converted contents, can be with keyframe content more visible in selecting video converted contents.
Step S206, when the video jump request of the point of the random time from client is received, judges random time Whether point hits the video time point in the video time line of the Video Quality Metric content for having cached.If so, then continuing executing with step S208, if it is not, then performing step S212.
