Description
Technical field
The present invention relates to field of computer technology, specifically provide it is a kind of based on SPICE protocol accelerate video method and be
System.
Background technology
Cloud desktop is a kind of important cloud computing application, it by system desktop, using desktop etc. as high in the clouds service to
User provides, and generally accesses cross-platform entire desktop system by client or other any equipment being connected with network
Wherein application program.Traditional computer desktop and PC are closely related, and separate unit host is limited in occupation mode
Resource constraint and spatial position, and installation, upgrading and the backup etc. of computer desktop are required for user oneself to complete.With tradition
Desktop application compare, cloud desktop can reinforce the dynamic allocation of the Unified Device management of computer terminal, safety management and resource,
Improve confidentiality and the safety of data information.
Cloud desktop is generally transmitted by the cloud resource pond, cloud terminal and the desktop of connection cloud resource pond and cloud terminal that virtualize
Agreement three parts form.Desktop transport protocol is the core of cloud desktop, and desktop transport protocol directly determines desktop function and display
Effect and network broadband occupancy situation, current main desktop cloud transport protocol have RDP, ICA, PCoIP, SPICE etc..Wherein
SPICE (simple protocol of independent computation environment, Simple Protocol for independent Computing
Environment it is) an open remote computing solutions, which provides the solution interacted with virtual desktop
Scheme, and increasing income completely, client can by the protocol access remote system desktop and using local device (such as
Keyboard, mouse and USB).By SPICE, we can access remote system as using local computer, in this way can be
CPU intensive work transfers long-range high-performance machine to from client, possesses on cloud desktop be widely applied at home.Cloud is whole at present
End generally uses the thin client of X86 or ARM frameworks.Wherein ARM has that low in energy consumption, noise is small, maintenance is simple compared with X86-based terminal
The characteristics of, and be widely used.But since the CPU of ARM frameworks is weak to multimedia processing capability, answered when there is HD video
The problems such as used time, there are video delay is serious, and audio and video are asynchronous and influence its user experience.
Invention content
The technical assignment of the present invention is in view of the above problems, to provide a kind of reduction ARM terminal video results of broadcast
The method for accelerating video based on SPICE protocol of difference and Caton phenomenon.
The further technical assignment of the present invention is to provide a kind of system accelerating video based on SPICE protocol.
To achieve the above object, the present invention provides following technical solutions：
A method of accelerate video, the method for accelerating video to install on a host server based on SPICE protocol
Qemu-kvm environment and virtual machine, and video player is installed in virtual machine, it is installed in terminal identical with host server
System, and SPICE clients are installed, terminal connects the remote virtual machine desktop of host server by SPICE clients, realizes
Video acceleration.
Preferably, the host server is CentOS6.4 systems.
Preferably, the terminal uses IM X 53.
Video processing unit VPU and graphics processing unit IPU, video processing unit VPU are integrated on 53 platforms of IM X
It is responsible for the decoding of video, video format is supported to have H264, VC-1, MPEG-1/2, MPEG4, MJPEG etc., highest to support 1080p's
Video decodes, and highest supports code check to be up to 40M bps.VPU has the ability to handle completely, can be used for doing the hard of client with VPU
Decoding.Meanwhile it being decoded into yuv format data flow and being rendered into some operations such as color conversion, stretching, contracting during display
It is also bigger the calculation amounts such as to put, is also taken very much with CPU to handle, and is handled using IPU then very fast, the time is in 1-
Between 2ms, almost it can be ignored.So SPICE protocol client end CPU decoding and flow for displaying are optimized, with VPU come
It does MJPEG decodings and IPU images is shown, decoding and the display efficiency of client can be increased substantially.
Preferably, the SPICE client releases are 0.12.0, SPICE clients use SPICE-client
v0.11。
Preferably, installing Window7 virtual machines in the host server.
Preferably, the method for accelerating video specifically includes following steps：
S1：Qemu-kvm environment and virtual machine are installed on a host server, video is installed in mounted virtual machine
Player；
S2：System identical with host server is installed in terminal, and SPICE clients are installed；
S3：After host server is provided with terminal, the remote dummy of host server is connected by SPICE clients
Machine desktop makes terminal be established with host server and connects, realizes video acceleration.
A kind of system accelerating video based on SPICE protocol, including host server and terminal, in the host server
Qemu-kvm environment and virtual machine to be installed, video player is installed in virtual machine, the terminal installs CentOS6.4 systems, and
SPICE clients are installed, terminal connects the remote virtual machine desktop of host server by SPICE clients.
Preferably, it is 0.12.0 that the terminal, which uses IM X 53, SPICE client releases, SPICE clients use
SPICE-client v0.11。
Preferably, installing Window7 virtual machines in the host server.
It is compared with prior art, of the invention that accelerate the method for video to have based on SPICE protocol following prominent beneficial
Effect：After the method based on SPICE protocol acceleration video is using hardware decoding, decoding time is greatly reduced compared with CPU, it is right
1080p HD videos, decoding time can control within 12m s, and from the point of view of actual test effect, video playing is smooth, virtual machine
Desktop operating experience is good, can solve video delay seriously, the nonsynchronous problem of audio and video brings good experience to user
Effect has good application value.
