Description
Technical field
The invention belongs to net cast technical fields, more particularly, to a kind of Video Rendering method based on GPU and are
System.
Background technique
Currently, net cast platform is very universal, user can watch them by net cast platform and wish to see
TV, film and game live streaming for seeing etc..Video Rendering is a kind of very common method for processing video frequency in net cast, is used
In the computer resource for saving user.Generally default using CPU render mode at present, but since CPU also needs to handle greatly
The other operations of amount, are used for Video Rendering, virtually can cause waste unnecessary to the computer resource of user.
Summary of the invention
Aiming at the above defects or improvement requirements of the prior art, the present invention provides a kind of Video Rendering sides based on GPU
Method and system, it is intended that the technology for solving waste user computer resource brought by existing simple CPU rendering mode is asked
Topic.
To achieve the above object, according to one aspect of the present invention, a kind of Video Rendering method based on GPU is provided,
The following steps are included:
(1) judge whether the browser between user opens net cast supports GPU to render, be transferred to step if supporting
(2), otherwise video is rendered using conventional CPU render mode；
(2) judge whether the type of browser between user opens net cast is Chrome browser, if it is into
Enter step (3), otherwise enters step (5)；
(3) default plays the video between net cast using CPU rendering, and sends rendering type selection command to user,
It is to select to render the video between playing net cast with GPU, or select to use CPU wash with watercolours that user is indicated in the rendering type instruction
Dye plays the video between net cast；
(4) it receives from user according to the rendering selected rendering type of type selection command, and according to the rendering type
The video between net cast is played, process terminates；
(5) default plays the video between net cast using GPU rendering.
Preferably, step (1) is rendered particular by the development language detection browser GPU of the player between net cast
Availability.
It is another aspect of this invention to provide that providing a kind of Video Rendering system based on GPU, comprising:
First module, judges whether the browser between user opens net cast supports GPU to render, and is transferred to if supporting
Otherwise second module renders video using conventional CPU render mode；
Second module, for judging whether the type of the browser between user opens net cast is Chrome browser,
If yes then enter third module, otherwise enter the 5th module；
Third module uses CPU rendering to play the video between net cast, and sends rendering type to user for defaulting
Selection instruction, it is to select to render the video between playing net cast, or choosing with GPU that user is indicated in the rendering type instruction
Select the video rendered between playing net cast with CPU；
4th module, for receiving from user according to the rendering selected rendering type of type selection command, and according to
The rendering type plays the video between net cast, and process terminates；
5th module uses GPU rendering to play the video between net cast for defaulting.
Preferably, the first module detects browser GPU wash with watercolours particular by the development language of the player between net cast
The availability of dye.
In general, through the invention it is contemplated above technical scheme is compared with the prior art, can obtain down and show
Beneficial effect:
(1) by the present invention in that realizing Video Rendering with GPU, by GPU in terms of video processing the advantages of performs to maximum
Change, and solves merely the technical issues of by waste user computer resource brought by CPU rendering mode；
(2) present invention selects different Video Rendering modes according to the type of different browsers, to reach user's broadcasting
Experience optimal effect.
Detailed description of the invention
Fig. 1 is the flow chart of the Video Rendering method the present invention is based on GPU.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.As long as in addition, technical characteristic involved in the various embodiments of the present invention described below
Not constituting a conflict with each other can be combined with each other.
As shown in Figure 1, the present invention is based on the Video Rendering method of GPU the following steps are included:
(1) judge whether the browser between user opens net cast supports GPU to render, be transferred to step if supporting
(2), otherwise video is rendered using conventional CPU render mode；Specifically, this step passes through broadcasting between net cast
Put development language (be in the present invention using Actionscript 3.0) the detection browsing of device (such as Flash player)
The availability of device GPU rendering；
Processing by GPU to software Graphics image can reduce the burden of CPU, so that application software can be with more
Fast speed is processed, that is to say, that can raise speed.
(2) judge whether the type of browser between user opens net cast is Chrome browser, if it is into
Enter step (3), otherwise enters step (5)；
(3) default plays the video between net cast using CPU rendering, and sends rendering type selection command to user,
It is to select to render the video between playing net cast with GPU, or select to use CPU wash with watercolours that user is indicated in the rendering type instruction
Dye plays the video between net cast；
(4) it receives from user according to the rendering selected rendering type of type selection command, and according to the rendering type
The video between net cast is played, process terminates；
(5) default plays the video between net cast using GPU rendering.
Specific implementation of the present invention is as follows:
(1) automatic mode: when entering direct broadcasting room, pass through the computer programming language of flash player exploitation
ActionScript3.0 provides stage.stageVideos.length！=0 (plays what external video can be used
StageVideo list object) interface detection current browser it is available with the presence or absence of GPU, if it does not exist, just use routine CPU wash with watercolours
Dye mode, while " opening GPU rendering " option being made in player right-click menu to set ash, it can not click；If it exists, then
Pass through flashActionScript3.0 technical interface Capabilities.manufacturer.toLowerCase ()
.indexOf("google")！=-1 (manufacturer when operation version or the AIR operation of Flash Player) is current to detect
The version of flashplayer in browser, if detecting is version built in chrome browser, default never call GPU (because
Under chrome, if opening GPU rendering, in the configuration video card operation of a part of computer, the bad effect for pulling screen barrage is had
Occur, so default is to close), while " opening GPU rendering " option being made in player right-click menu to be the state that can be clicked,
Otherwise there is available GPU then to default unlatching under non-chrome browser and call GPU rendering, and make in player right-click menu
" closing GPU rendering " option is the state that can be clicked.
(2) it manual mode: in video playing, if default opens GPU rendering automatically, can also be turned off manually
GPU rendering switches to CPU rendering；At chrome, default be close GPU render, once CPU exorbitant expenditure, can open
GPU rendering, reduces the consumption of CPU.Whole operation step is: clicking popup menu option by right key on a player, has and " close
The option of the two one of GPU rendering " or " opening GPU rendering ", chooses option to click, will send instruction to player and cut
Another rendering play mode is changed to, for example is switched to GPU render mode from CPU, or be switched to GPU rendering mould from CPU
Formula, video flowing will play out under selected render mode.
As it will be easily appreciated by one skilled in the art that the foregoing is merely illustrative of the preferred embodiments of the present invention, not to
The limitation present invention, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should all include
Within protection scope of the present invention.
