Description
Technical field
The present invention relates to the video playback technical field, concretely, relate to a kind of computer multi-video player method and device.
Background technology
Watch video, become the main application of PC.Particularly get into today of huge numbers of families in the Internet, network and Internet video become the brand-new channel of multimedia information dissemination.No matter various video contents are the individual videos of being made by domestic consumer, and the video frequency program of still being made by professional media can both let Internet user all over the world pass through network download or online playing whenever and wherever possible.
Original vision signal need could guarantee under the prerequisite that guarantees the audio frequency and video quality to greatest extent through overcompression, coding, reduces the size of video file, reduces the bandwidth requirement in the Network Transmission.And, on user's computer, need decoding be reduced into the video that to watch through the video of overcompression and coding.
The Code And Decode algorithm of video is comparatively complicated; Particularly high to those compression ratios, the video that the audio frequency and video quality is high is if adopt the mode encoding and decoding of software; Can consume a large amount of system resource, the disposal ability of CPU, the size of internal memory are all had very high requirement.For this reason, make in a large number at needs, during transmission of video, need coded hardware equipment; And,, all can adopt decoding chip to reduce video like STB, MP4 player or the like at some Embedded equipment.
Initial video all is to propagate with the mode of file basically, and the copy that the user need download to video file fully afterwards could begin to watch, and because video file is bigger, therefore needs to wait for for a long time.For this reason, based on network streaming media video arises at the historic moment, and watches streaming media video while the user can download.The birth of streaming media video lets network TV IPTV become the field that telecom operators and video content merchant emphasis drop in recent years.The user is can be on broadband network online to watch various videos.In addition, along with popularizing of video DV equipment, domestic consumer also can make individual video as professional media.Therefore diverse network video sharing website also has been born.What no matter the user used is any Video service, and the video pictures that can watch decoded, be reduced into to the video content of which kind of form that obtains, final video all will through " video player ".
Current, the main operational mode of the video player of main flow comprises: the pattern of stand-alone utility pattern (window scheme), embedded web page browser and played in full screen pattern.
Under window scheme, as common computer applied algorithm, the user can use functions such as the menu, Play Control button, minimax window of player.
The pattern of embedded web page browser is slightly different with window scheme, and button and right-click menu that some control of video are play are retained, and minimize, function such as menu all is removed.For the various websites that Internet video content and service are provided, can both see on webpage, having embedded video player that the user can watch corresponding video content in browsing page information in the overwhelming majority.
No matter be window scheme or embedded web page pattern, the user can promptly let video pictures monopolize whole display space full frameization of video.In the screen mode toggle, video scaling, control (time-out, F.F. etc.) function all can be superimposed upon on the video pictures, and the user need not withdraw from screen mode toggle can realize the control to video.Screen mode toggle is that the user is watching conventional video such as TV, film to experience for a long time.Under full frame situation, the concern of video council sole user, full frame requirement to video quality simultaneously is also very high.
All in the market video players have all adopted as above three kinds of patterns.Explain that the network user has formed the acquired behavior pattern that Internet video is watched gradually on the one hand, explain also that on the other hand this simple video pattern of watching exists the crucial more difficult problems that can't overcome, and comprising:
(1) single video
In arbitrary moment of these video players, in a player, can only play one section video.When the user need obtain a plurality of video content, can only realize through the mode of opening video window more.A plurality of video windows can cause such as sound and be mingled in together, take more system resource or the like problem.User experience can only use confusion to describe.And, at present on the PC that specific video card is not installed, can not when video of played in full screen, on screen, play another video simultaneously, the mode with pure software of promptly being difficult to realizes the picture-in-picture (PIP) under full frame.
(2) video and information separated
A large amount of picture, text and Flash content on the network only could coexist with video in webpage.And video to a great extent, because its particularity, is huge to the attraction of user's attentiveness, therefore is difficult to go the content of noticing that these are relevant again.Under the play mode of full frame or window, the user can't get access to the information of other types when watching video in addition.
The above problem that the conventional video player exists has limited the generation of innovation Video Applications and service greatly, has especially hindered the development of web advertisement video market.
Advertisement is one of successful business model of the Internet.The legacy network advertisement is main with picture, Flash and content of text, and the brand strength that video ads can transmit is that traditional approach is incomparable.But present video ads pattern comprises following dual mode:
(1) video (like Yahoo Movie) that in the program video playing process, breaks for commercialsy
Identical with television advertising, video ads inserts in the process of playing programs, replaces original video fully.For this mode, on the one hand the user experiences poor, and user's the behavior of normally watching is interrupted, and often during advertisement video is play, the user can shift it and watch and a little do other things.On the other hand, the commercial breaks video can only have two kinds of implementations:
Just advertisement is sheared into when 1) programming video
This just need drop into a large amount of human and material resources in the video editing in early stage, in case and video production just can't be made amendment to ad content after accomplishing.
2) often only, program video intercuts when playing beginning and finish
So wasted a large amount of effective advertisement opportunity and time, and beginning and when finishing user's attentiveness be difficult to and can be placed on the video fully.And such advertisement putting comparatively speaking and watch and still isolating between the process of program, and the user can't select, so user experience and bad.
(2) video ads (like iCast) appears on the page
When the user mixes browsing page, rise video ads automatically.The large-area web page contents that sheltered from, the user does not select.Therefore user experience is poor, and most this type of advertisement all can can't be ejected by browser or tool bar shielding.
In addition, Internet video is that infinite channel can be arranged in theory, and this point is different with the channel of traditional tv fixed qty.But individual for the user, its attentiveness is limited.And the various contents of broadcasting in the Internet video channel of these magnanimity under the situation of single video, do not let the user enjoy the right of selection fully.
Along with watch popular shared in the increase-volume of the network bandwidth, the decline of cost of video storage with video; " video " become the new focus in the Internet; Yet the above defective that conventional video playing programs and video ads are thrown in; Greatly limit the generation of the application and service of video playback, also hindered the innovation and the development of Video service business model.

Embodiment
For making the object of the invention, technical scheme and advantage clearer, specific embodiment of the present invention is elaborated below in conjunction with accompanying drawing.
Embodiment 1
Present embodiment is to use Direct3D (the being called for short D3D) technology of Microsoft, utilizes Direct3D can handle the ability of a plurality of Drawing Objects simultaneously, realizes that a plurality of videos show (picture-in-picture function) simultaneously under full screen.
In the present embodiment; Realize that the basic principle that the computer video picture-in-picture shows is: describe the position and the size of a video/picture/literal with two or more triangles, the power function that then these leg-of-mutton data is input to D3D shows them.
The video of computer generally is 4: 3 a rectangle; Can represent that the texture object (texture) that the data bitmap of video uses D3D to support is described, and carries out related with above-mentioned two triangles this texture with the right-angled triangle that two hypotenuses link to each other; Then the function of these data inputs D3D; Just can demonstrate a frame video, show follow-up frame of video continuously, just can obtain the picture of video playback with assigned address and size.
Utilize same operation principle, just can on a secondary picture, put into different a plurality of video/picture/literal, describe with a series of triangle, the function of disposable then input D3D shows.Constantly this action of cycle repeats just can obtain the effect that a plurality of video/picture/the literal weave in shows simultaneously.
Utilize the characteristics of video per second 25 frames, the display refresh rates of D3D also was arranged to for 25 frame/seconds, can obtain smooth broadcasting pictures, also controlled the consumption of CPU and internal memory well.This is because the disposal ability of D3D can show a lot of triangles simultaneously and add texture within one second; And a video/picture/literal object just can be described with two triangles by our system; The object that on screen, occurs simultaneously generally is no more than 50, and (too many object can cause picture chaotic; Seldom occur in the reality); So the number of triangles that per second need show in the time of in fact most of is 50*2*25=2500, only account for the 2500/3000000=0.08% of machine (like notebook computer) the D3D triangle disposal ability of low configuration.And the bitmap size of a frame video generally is 640*480, and the bitmap that need handle video a second is counted and is 640*480*25=7.68M, only accounts for the 7.68M/242.6M=3.17% of machine (like notebook computer) the D3D texture processing ability of low configuration.This shows that D3D can be competent at fully for handling the so high dynamic dataflow of plurality of video.
D3D support window and full frame two kinds of display modes, and can between two kinds of patterns, switch at any time, the function of two kinds of display mode supports is consistent.Because the mode that we realize is directly to utilize D3D to realize the function that many videos and picture and text superpose, these functions all are the same at window with performance under full frame.
D3D supports mouse function under window and screen mode toggle, in video display process, when computer is received the incident of click; According to the coordinate position of mouse, in the picture list object, to search, the picture object all includes information such as position size; Can judge in view of the above mouse is to have clicked which object; If the related action of this object definition, Play System can be carried out this action, and this action can be the function of wide range; Such as certain object is shown/hide other objects of generation/destruction etc.So just can to the user mutual function be provided for the user provides further information.
Our system's per second shows that before each the demonstration, attributes such as leg-of-mutton position size and texture can change, so picture/Word message that system can provide real-time update to show changes the position size, make functions such as animation effect 25 times.
Though be to adopt the D3D function to realize that the picture-in-picture of many videos shows that the present invention is not limited to this in the present embodiment.Adopt OpenGL, DirectShow etc. can a plurality of visual objects to be handled equally with similar computer graphical of D3D and video processing interface, and come out in same screen displayed, the effect that just reaches is difficult to compare mutually with D3D.
As adopt other 3D technology, like OpenGL, can reach the repertoire that D3D realizes our system too, but OpenGL towards be the professional user, hardware is had higher requirements.In addition; The control VMR9 that Microsoft provides in DirectShow SDK (Video Mixing Render 9); Also can realize the demonstration that on screen, superposes of the decoded video flowing of two-way; But VMR9 has more problem on using, and perhaps changes size such as being difficult to smoothly the small video window moved, has bigger efficiency etc. when showing than multi-object.
Fig. 1 is a schematic flow sheet of in same screen, realizing many video playback of the present invention.As shown in Figure 1, can comprise the steps:
(1) reads XML (eXtensible Markup Language, extend markup language) configuration file
Available XML configuration file comes many video playback are configured in the present embodiment.When various content of multimedia show in a concentrated interactive interface simultaneously, not only need coordinate various contents synchronously, substep shows, and need process user mutual, respond to users action or the like.Therefore need define template, playing plan and script in advance, so that video content and other multimedia messagess are controlled, and be responsible for communicating by letter, at any time the control signal of process user with service end.Can come predefined template, playing plan and script etc. are configured through the XML configuration file.Also comprise a plurality of (comprising two) source of media information that needs are play in the said configuration file.
Said configuration also can realize through manual configuration or through input command is capable.
(2) generate interface element according to configuration file, and the various attributes of interface element are set.
Corresponding to the number of the medium that will play, generate the interface element of same number.At this, said interface element comprises big or small position, transparency, the animation effect interface display parameters such as (as are fade-in fade-out, rotate) of video, and the attribute that interface element is set also promptly is provided with said interface display parameter.The interface element that is provided with can send the unit that will carry out video display to the formation form.Just can control the display effect of medium when the media play of correspondence according to the interface element that is provided with.
(3) generating medium according to the configuration in the configuration file reads Control Parameter, medium source address is set (like URL; URL; Be network address), and (comprise media file and Media Stream etc., these medium both can be positioned at local computing to read corresponding medium according to setting; Also can be positioned at far-end server), and separately the medium bag is decoded into video requency frame data and tonepulse modulating data.Corresponding to a plurality of medium, be decoded into corresponding multi-channel video frame data and tonepulse modulating data altogether.As show at the same time under the situation of 2 videos, then will 2 media decodes be become 2 road video datas and 2 road voice datas according to 2 source of media corresponding address.
At this, it is the parameter that is used to control medium time for reading or frequency that described medium read Control Parameter.As, control the medium that generate auxiliary form and whenever read broadcast once at a distance from 5 minutes, perhaps when connecting, downloading and cushioning, read broadcast etc. at the main viewfinder medium.This parameter can make amendment and be provided with as required easily.
(4) according to the setting of interface element, the multi-channel video frame data that decoding is generated show at the different forms of same screen.The concrete step that shows is as shown in Figure 2.
Video represents in the unit continual inspection interface element formation whether the interface element that need represent is arranged; After video represents the unit and finds that the element that need represent is arranged; To display parameters be set according to interfacial structure unit designated parameters, the interface element that from formation, will represent then takes out.
Video represents the unit will resolve into triangle by the interface displayed element, if the interface element that represents is a video, video represents the unit will obtain the data bitmap of frame of video from carry out unit that source of media reads, and will convert thereof into texture object.
Video represents the unit according to the display parameters that obtained, data texturing, and leg-of-mutton texture, position, size are set.Calling the D3D interface then will be outputed in the middle of the picture buffer by the interface element display frame that various triangles constitute.
At this moment video represents the unit and will check whether the demonstration of previous frame picture has pass by 1/25 second, if not then wait for, if pass by 1/25 second, then calls the D3D interface display frame in the picture buffer is outputed on the computer screen.
Video represents device can constantly repeat process shown in Figure 2, lets smooth the playing back of video.
In the different forms that shown, as main viewfinder, other form is as auxiliary form with one of them form.As can be with the display size that is provided with big form is as main viewfinder.
(5) select as required the audio data decoder of some source of media is play.
Usually, with main viewfinder in frame of video corresponding audio decoded data play output.
Through step as above, just realized having many video playback effect of picture-in-picture function.Not only can avoid the dullness of single video, can not cause mixing of sound again; And when playing main video, if media contents such as commercial breaks need not when making main video media, advertisement to be sheared into, and play at any time; And, owing to the position size that can control the advertisement page, transparency etc., in time when playing main video media, play, can not influence very much the viewing effect of main video media yet, therefore improved user experience greatly.
Utilize the 3D technology; Many video broadcasting methods of the present invention can be supported at least two video window experience seamless, mutual superposition smoothly (picture-in-picture function): be divided into main video window and auxilliary video window like picture, the sound that the user hears is sound played in the main video window.
The present invention can also on the video playback interface, superpose a plurality of auxiliary videos, Flash, picture and content of text, and the setting through interface element can be supported in the roll titles that superposes on the video (comprising literal, picture).The content of captions and relevant parameter all can be provided with.
The present invention also can be switched main video window and auxilliary video window through shortcut is set, and is about to the main video frequency program of broadcast simultaneously and the broadcast position of auxilliary video content and exchanges.Auxilliary video content broadcast accomplish after, the main program video all will come back to the main broadcaster and put window and play.
The present invention intercuts video ads when also being supported in the P2P connection, downloading and cushioning.When client end of playing back connects or during switching channels first, can be because connect, download and buffering and cause main video window not have play content.This moment, client was thrown in the arrangement of planning according to auxiliary video, broadcasted advertisement at main video window, showed the progress that connects, downloads and cushion simultaneously.After main video frequency program cushions completion, directly play, and automatically advertisement video is switched to auxilliary video window continuation broadcast at main video window, finish playing until auxiliary video.
The present invention supports hyperlink equally.On the content (literal and picture) of advertisement video, picture, roll titles, can specify hyperlink.After the user clicks auxiliary video window, picture and word content, eject new browser window and open corresponding link.
In the process of switching major-minor video window, the appearance of auxiliary video content, the present invention supports various scenes to switch effects.As: 1. be fade-in fade-out, 2. spring into ejection, 3. fly into the switching of the effect that flies out.
The present invention also supports full frame and window is play.When the user double-clicks in the video playback position, automatically switch to window or played in full screen mode.
The present invention can be the shortcut that the user provides mouse action and keyboard, does following action: switch main video window and auxiliary video window 1.; 2. the switching between full frame and window is play; 3. switch the broadcast address (channel switching) of main program video.Channel like each program video can be superimposed upon on the main program video window with written form, and the shortcut through click corresponding channel or operation keyboard can carry out the switching of channel.
The present invention also can provide independent client application.User directly running client program can watch main video flowing and correspondent advertisement to throw in content.The operating system that needs to support comprises: WindowsXP and Windows 2003.
In addition, but in the client embedded web page.But client Embed is in webpage, and embedded client can be play main video frequency program and advertisement putting content equally.Support same interactive operation (mouse and keyboard shortcut etc.).In addition, the user can realize that through the channel link of clicking in the page channel switches.
Many video broadcasting methods of the as above picture-in-picture of present embodiment can be realized with software, hardware or way of hardware and software combination.As producing the new video player that carries out many video playback according to as above step, to run on the computer through software.Video player of the present invention can comprise like lower module (being shown as example with the picture-in-picture that comprises 2 videos describes):
