The embodiment of the present invention provides a kind of method for processing video frequency, client and system, by the video in the time point both sides of suspending position is carried out to repeatedly sectional drawing by characteristic frequency, choose the picture having near the time point that suspends position and be presented in chronological order in the picture wall on video upper strata, make user very clear near video image corresponding to each time point time point of time-out position.User can accurately hold the playing progress rate of video by this picture wall, thereby accurately locates preedited time point, improves and gets editor's accuracy ready and get efficiency ready.Below be elaborated respectively.
Refer to Fig. 1, Fig. 1 is the schematic flow sheet of a kind of method for processing video frequency of providing of the embodiment of the present invention, and in embodiments of the present invention, the method comprises the following steps.
S101: in editing saving process, obtain the object time stamp that image shown in the time that editing video suspends is corresponding.
As one embodiment of the present invention, user is in editing saving process, while seeing interested broadcast point, suspend and treat editing video, client according to shown image acquisition in the time that editing video suspends to the rough position of getting ready, further, obtain this rough object time that the shown image in position is corresponding of getting ready and stab, be i.e. time out point.For example: user enters editing saving system and chooses recording task and play, beginning or end place in interested video end suspends, the mode that system arranges time-out comprises click " broadcasting/time-out " button, pulls progress bar or use correct time point location button, obtains the object time stamp that while time-out, shown picture is corresponding.As shown in Figure 7, Fig. 7 be the embodiment of the present invention provide a kind of video playback time status bar schematic diagram, in the figure, be provided with three kinds of suspended patterns that click " is play/suspended " button, pulls progress bar or use correct time point location button, facilitate user to input the rough position of getting ready.Generally, the real interested video location of user is positioned near this time out point, therefore, in embodiments of the present invention, client is by obtaining behind the time-out position of editing video, show fast near the video image this time-out position on video upper strata by the mode of picture wall, facilitate user further to choose accurately the interested position of getting ready by the video image in this picture wall.
S102: according to default parameter information and stamp of described object time, generate N bar sampling instruction, N is positive integer.
As one embodiment of the present invention, default parameter information comprises that sectional drawing frequency f, single sectional drawing count M and sectional drawing sum L, and single sectional drawing is counted the value of M in preset range, and preset range can be 10～25.Carry out video while getting ready, can pre-set this parameter information, arrange or by user's manually input in the status bar window of video playback by software.For example: be 1 of sectional drawing per second by software program by sectional drawing frequency f default setting, for example, carry out sectional drawing by characteristic frequency (1 width/second); Single sectional drawing is set in status bar window, and to count M be 13; Sectional drawing sum L is 60, as the numerical value of institute's mark in Fig. 2.Client is obtained the time-out position for the treatment of editing video, determines the times N of sampling instruction according to default parameter information, for example: M=13, when L=60, N=5, i.e. L=M*4+8; M=10, when L=40, N=4, i.e. L=M*4.Preferably, can be the frame per second that is set to video by software sectional drawing frequency f, single sectional drawing is counted M and is set to 13, by user, sectional drawing sum L is manually set.
Obtain after parameter N, according to the time out point getting and default parameter information, in the video of both sides, selected time-out position, generate N bar sampling instruction, so that N sectional drawing operation carried out in the time point both sides that server is selected user, each sectional drawing operate according to default sectional drawing frequency acquisition M pictures, until the picture being truncated to stops sectional drawing while being the total L of sectional drawing setting in advance.Wherein, every sampling instruction is separate, and server can directly carry out sectional drawing operation according to the entrained information of this sampling instruction while receiving a wherein sampling instruction.
As one preferred embodiment, obtain after parameter N, first according to object time stamp and parameter information, generate Article 1 sampling instruction.Concrete, point centered by object time stamp, obtains respectively (M-1)/2 sampling time stamp according to sectional drawing frequency f to both sides, generate the Article 1 sampling instruction of M the sampling time stamp that comprises object time stamp.Then according to first sampling time stamp of Article 1 sampling instruction, M sampling time stamp and default parameter information, obtain M sampling time and stab to one-sided respectively according to sectional drawing frequency f, generate the instruction of sampling of remaining N-1 bar.
For example: f=1 width/second, M=13, when L=60, calculate N=5, hypothetical target timestamp is 19:00:00, and point centered by object time stamp 19:00:00, obtains respectively (M-1)/2 sampling time stamp according to sectional drawing frequency f to both sides, i.e. (M-1)/2=6,6 sampling time stamps that get are to the left: 18:59:54, 18:59:55, 18:59:56, 18:59:57, 18:59:58, 18:59:59, corresponding, 6 sampling time stamps that get are to the right: 19:00:01, 19:00:02, 19:00:03, 19:00:04, 19:00:05, 19:00:06, therefore, can generate the Article 1 sampling instruction of M the sampling time stamp that comprises object time stamp, and server will carry out sectional drawing: 18:59:54 at following 13 sampling time stamp places after receiving Article 1 sampling instruction, 18:59:55, 18:59:56, 18:59:57, 18:59:58, 18:59:59, 19:00:00, 19:00:01, 19:00:02, 19:00:03, 19:00:04, 19:00:05, 19:00:06, meanwhile, often obtains a sampling time stamp and updates sectional drawing quantity, can mark sectional drawing quantity be 13 generating after Article 1 sampling instruction.What deserves to be explained is, if M=12, point centered by object time stamp 19:00:00, obtains 5 sampling time stamps to the left, obtains to the right 6 sampling time stamps or obtains to the right 6 sampling time stamps, obtains to the left 5 sampling time stamps.Obtain after Article 1 sampling instruction, if the sectional drawing quantity of institute's mark is less than sectional drawing sum L, generate remaining N-1 bar sampling instruction in the specified sampling time stamp both sides of Article 1 sampling instruction.For example: Article 2 sampling instruction is taking first sampling time stamp 18:59:54 of Article 1 sampling instruction as end caps, obtain to the left M sampling time stamp according to sectional drawing frequency f, can obtain the specified sampling time stamp of Article 2 sampling instruction is: 18:59:41,18:59:42,18:59:43,18:59:44,18:59:45,18:59:46,18:59:47,18:59:48,18:59:49,18:59:50,18:59:51,18:59:52,18:59:53, meanwhile, upgrading sectional drawing quantity is 26.Obtain after Article 2 sampling instruction, the sectional drawing quantity of institute's mark is still less than sectional drawing sum L, therefore, continues to obtain Article 3 sampling instruction.For example: Article 3 sampling instruction is stabbed 19:00:06 as initial end points taking M the sampling time of Article 1 sampling instruction, obtain to the right M sampling time stamp according to sectional drawing frequency f, can obtain the specified sampling time stamp of Article 3 sampling instruction is: 19:00:07,19:00:08,19:00:09,19:00:10,19:00:11,19:00:12,19:00:13,19:00:14,19:00:15,19:00:16,19:00:17,19:00:18,19:00:19, meanwhile, upgrading sectional drawing quantity is 39.Obtain after Article 3 sampling instruction, the sectional drawing quantity of institute's mark is still less than sectional drawing sum L, therefore, continues to obtain Article 4 sampling instruction.For example: Article 4 sampling instruction is taking the 1st sampling time stamp 18:59:41 of Article 2 sampling instruction as end caps, obtain to the left M sampling time stamp according to sectional drawing frequency f, can obtain the specified sampling time stamp of Article 4 sampling instruction is: 18:59:28～18:59:40, sampling interval is 1 second, meanwhile, upgrading sectional drawing quantity is 52.Obtain after Article 4 sampling instruction, the sectional drawing quantity of institute's mark is still less than sectional drawing sum L, therefore, continues to obtain Article 5 sampling instruction.For example: Article 5 sampling instruction is stabbed 19:00:19 as initial end points taking M the sampling time of Article 3 sampling instruction, obtain to the right sampling time stamp according to sectional drawing frequency f, making sectional drawing quantity is sectional drawing sum L, so, can obtain Article 5 sampling instruction and comprise 8 sampling time stamps, be respectively: 19:00:20,19:00:21,19:00:22,19:00:23,19:00:24,19:00:25,19:00:26,19:00:27, now, sectional drawing quantity is L, stops obtaining the step of sampling time stamp.As shown in Figure 8, Fig. 8 is a kind of view of obtaining sampling time stamp that the embodiment of the present invention provides.
Accordingly, can be also that client is stabbed according to default parameter information and object time, generate N bar sampling instruction, every sampling instruction notification server carries out sectional drawing according to the sectional drawing frequency of appointment within the time period of specifying.
What deserves to be explained is, suspend after video, user waits for that the time that picture wall shows comprises the time that time, network service time, the server of client tissue sampling instruction are carried out the time of sectional drawing, client parsing and shown, in the situation that configuration is identical, period of reservation of number is mainly carried out the Time dependent of sectional drawing by server, and server carry out sectional drawing time mainly with server sectional drawing quantity number relevant, after tested, time and the sectional drawing quantity of server execution sectional drawing are directly proportional substantially.For example: under equal conditions server intercepts 13 images and needs 1.3s, needs 7.4s while intercepting 60 images, needs 13.0s while intercepting 100 images.If user clicks time-out on video, server is only carried out a sectional drawing operation according to sectional drawing sum L, i.e. N=1, and sectional drawing sum L value will cause user's stand-by period very long when very large, generally wants 10s left and right, has a strong impact on user and experiences.Therefore, the embodiment of the present invention arranges separately respectively single sectional drawing and counts M and sectional drawing sum L, single sectional drawing is counted to M and be arranged in a suitable numerical value interval, for example: between 10～25, as M=13, sectional drawing sum L need to arrange according to user, conventionally, sectional drawing sum L is greater than 25.Wherein, single sectional drawing is counted M too hour, after the picture that client obtains to server Article 1 sampling instruction, cannot be paved with picture wall, when too large, the client awaits time is longer, therefore, M is arranged in a suitable numerical value interval, conventionally, in picture wall, generally can shows 10 pictures, concrete, determined by the resolution of client display screen; Meanwhile, too hour, user choice is few for sectional drawing sum L, and when too large, waste resource, therefore, can be arranged on sectional drawing sum L between 25～200.For example: M=13, when L=200, count according to set single sectional drawing that M and sectional drawing sum L is known need send 16 sampling instructions to server, L=M*15+5, server is carried out 16 sectional drawings operations.Preferably, server is carried out the specified sectional drawing operation of Article 1 sampling instruction that comprises object time stamp at first, often execute after the operation of a specified sectional drawing of sampling instruction, the picture being truncated to is issued to client, client after the sectional drawing picture of Article 1 sampling instruction, can in picture wall, show comprise time out point picture and near picture.Thereby, period of reservation of number only comprises the time of implementation of sectional drawing operation for the first time, and after sectional drawing result is returned for the first time, client Shows Picture in picture wall, when user selects interested picture in picture wall, the new picture that reception server sends over successively.
Preferably, the arranging of parameter M and parameter L meets N and is greater than 1, and while making user get one time ready, client sends at least 2 sampling instructions, and every sampling instruction is separate, thereby server is carried out at least 2 sectional drawings operations, saves the sectional drawing time.For example: in the situation that sectional drawing sum L is certain, if server is carried out 1 sectional drawing operation, client just can show after needing waiting for server to intercept L pictures, and the stand-by period is m second; If adopt the method for the embodiment of the present invention, suppose that client sends 5 sampling instructions, client can show after only needing waiting for server to intercept L/5 pictures, period of reservation of number is m/5 second, thereby has greatly shortened user's stand-by period.Generally, server is multithreading equipment, and client sends after N bar sampling instruction, the sectional drawing operation that server can this N bar sampling instruction of executed in parallel, shared time while being L/N pictures time that server is carried out sectional drawing operation.If server is single-threaded equipment, client sends after N bar sampling instruction, server can identify Article 1 sampling instruction according to entrained information in every sampling instruction, the preferential specified sectional drawing of Article 1 sampling instruction of carrying out operates, the picture being truncated to is returned to client to be shown, and other the specified operation of sampling instruction is carried out in continuation, and client is specified after associated picture to Article 1 sampling, in picture wall, load the picture of both sides, position, breakpoint, recognize in interested picture process user, the client associated picture of other sampling instruction that reception server sends over simultaneously, the stand-by period that is equivalent to subsequent sampling instruction sectional drawing is 0.No matter sectional drawing adds up to how many, user's stand-by period is server and intercepts Article 1 specified sampling time of instruction of sampling and stab the time that the picture that is associated spends, thereby has avoided the contradiction between sectional drawing sum and period of reservation of number.The method for processing video frequency that adopts the embodiment of the present invention to provide, user waits for that the time of sectional drawing is very short, gets efficiency ready high.
S103: send described N bar sampling instruction to server, so that described server is carried out the sectional drawing operation of specifying according to every sampling instruction, and the picture after intercepting and the timestamp being associated are sent to client.
Obtained after sampling instruction by S102, the sampling instruction getting is sent to server, preferred, request mark is set to sampling instruction, each sampling instruction of mark respectively simultaneously, receives after sampling instruction server, the sectional drawing operation of priority treatment Article 1 sampling instruction.Server intercepts picture according to sampling time stamp entrained in sampling instruction, and the picture after intercepting and the timestamp being associated are sent to client.
S104: receive the picture that described server sends, choose and there is the Image Display stabbing near the described object time in picture wall, in described picture wall, shown picture, to have centered by the picture of described object time stamp, is arranged according to the sequencing of timestamp.
As one embodiment of the present invention, after the picture that client sends over to server, by Image Display in the picture wall on video upper strata, conventionally, owing to being subject to the restriction of client display resolution, in picture wall, often can only show the picture of specific quantity, all pictures that are truncated to all can not be presented in picture wall.Suppose can only show 7 pictures in picture wall, after the picture that client sends over to server, obtain the associated picture of Article 1 sampling instruction, from 7 included pictures of Article 1 sampling instruction, choose to have centered by the picture of object time stamp, 7 pictures that arrange to both sides according to the sequencing of timestamp, get final product to such an extent that the corresponding timestamp of picture that is presented in picture wall is: 18:59:57, 18:59:58, 18:59:59, 19:00:00, 19:00:01, 19:00:02, 19:00:03, as shown in Figure 9, Fig. 9 is the interface schematic diagram of a kind of method for processing video frequency of providing of the embodiment of the present invention, the broadcasting pictures that video suspends is the object time to stab associated broadcasting pictures, in the picture wall of bottom, video upper strata, show the picture centered by the picture of object time stamp, get ready accurately for user.
In the described method for processing video frequency of the embodiment of the present invention, obtain the object time stamp that image shown in the time that editing video suspends is corresponding, according to default parameter information and object time stamp, generate N bar sampling instruction, N is positive integer, so that server is carried out the sectional drawing operation of specifying according to every sampling instruction, client is chosen the Image Display with close object time stamp in picture wall, makes user very clear near video image corresponding to each time point object time stamp.Thereby user can accurately hold the playing progress rate of video by picture wall, accurately locate preedited time point, improve the accuracy of getting editor ready, get efficiency ready high, and saved user's stand-by period.
Refer to Fig. 2, Fig. 2 is another schematic flow sheet of a kind of method for processing video frequency of providing of the embodiment of the present invention, and in embodiments of the present invention, the method comprises the following steps.
S201: in editing saving process, obtain the object time stamp that image shown in the time that editing video suspends is corresponding.
For example: user is in the process of watching video, obtain playing pictures corresponding to point-of-interest place or forward/backward if want to interested broadcast point, suspend the video of playing, according to the rough position of getting ready of input, obtain the object time that image shown in the time that editing video suspends is corresponding and stab.
S202: according to described object time stamp and described parameter information, centered by described object time stamp, point obtains respectively (M-1)/2 sampling time stamp to both sides, generates the Article 1 sampling instruction of M the sampling time stamp that comprises described object time stamp.
Preferably, default parameter information comprises that sectional drawing frequency f, single sectional drawing count M and sectional drawing sum L, and this parameter information can arrange by software in program, also can manually be inputted by user by the mode of window.Preferably, single sectional drawing is counted the value of M in preset range, for example: between 10～25, the numerical value that single sectional drawing is counted M and sectional drawing sum L meets N>1.Concrete, the embodiment of the present invention is not restricted this, and for convenience of description, the embodiment of the present invention is taking sectional drawing frequency f as 1 width/second, and it is 13 that single sectional drawing is counted M, and it is example that sectional drawing sum L is 60.If it is odd number that single sectional drawing is counted M, according to object time stamp and parameter information, centered by object time stamp, point obtains respectively (M-1)/2 sampling time stamp to both sides, generates the Article 1 sampling instruction of M the sampling time stamp that comprises object time stamp; If it is even number that single sectional drawing is counted M, according to object time stamp and parameter information, centered by object time stamp, point obtains respectively (M-1)/2 and (M-1)/2+1 sampling time stamp to single, generates the Article 1 sampling instruction of M the sampling time stamp that comprises object time stamp.For example: when M=10, point centered by object time stamp, obtains to the left 5 sampling times and stab, obtain to the right 4 sampling times stamps, or obtains to the left 4 sampling times and stab, obtain to the right 5 sampling times stamps.For convenience of description, the embodiment of the present invention take M as example as odd number.Preferably, for economizing on resources, the span of this parameter information can be set by software, for example: the span of single sectional drawing number is set to 10～25, and the span of sectional drawing sum is set to 25～200.
S203: according to first sampling time stamp of described Article 1 sampling instruction, M sampling time stamp and described parameter information, obtain M sampling time and stab to one-sided respectively, generate the instruction of sampling of remaining N-1 bar.
S204: send described N bar sampling instruction to server, so that described server is carried out the sectional drawing operation of specifying according to every sampling instruction, and the picture after intercepting and the timestamp being associated are sent to client.
Preferably, can be that client first sends Article 1 sampling instruction to server, after of short duration time delay, send all the other N-1 bar sampling instructions to server again, ensure the specified sectional drawing operation of server priority treatment Article 1 sampling instruction, further ensureing just to comprise in picture that client receives at first the object time stabs associated picture, thereby shortens user's stand-by period.What deserves to be explained is, the embodiment of the present invention does not limit the execution sequence of S204 and S203, also can be this Article 1 sampling instruction to be sent to server after client obtains Article 1 instruction, and then obtain remaining N-1 bar sampling instruction, then this N-1 bar sampling instruction is sent to server.
S205: receive the picture that described server sends, choose and there is the Image Display stabbing near the described object time in picture wall, in described picture wall, shown picture, to have centered by the picture of described object time stamp, is arranged according to the sequencing of timestamp.
S206: while receiving shifted left/right triggering command, left/right loads and shows a new picture.
