Abstract
The invention provides a multimedia accelerating system based on virtualization. The multimedia accelerating system based on the virtualization comprises a virtualized core layer, a decoding layer and a data source access layer, wherein the data source access layer is used for seeking out and accepting source data and then delivering the source data to the decoding layer after the source data are transcoded by a CODEC; the decoding layer is used for decoding received data source access layer data and then feeding the decoded data source access layer data back to the virtualized core layer for processing in an RTP package mode; the virtualized core layer is used for forwarding request and receipt data. The multimedia accelerating system based on the virtualization carries out audio and video coding and decoding by the utilization of a computer network processing accelerator card and the virtualization which are matched, greatly promotes hardware performance, promotes multimedia experience effect, and is simple, flexible and extensible in application.
Description
Technical field
The present invention relates to technical field of virtualization, relate in particular to a kind of based on virtualized multimedia accelerating system.
Background technology
Server virtualization, desktop virtual and applying virtualization are three big Intel Virtualization Technologies in now computer virtualized.It also is an important technology of following cloud computing.At present at the industry-by-industry in the whole world, begun the popularization of virtualized technology, and in the IT industry, coming into one's own gradually.
Current audio/video encoding/decoding is handled hard decoder and soft decoding dual mode, because the resolution of HD video is higher than the general format video far away, makes that the code check of HD video is very high.The compression ratio of adding VC-1 and H.264 encoding is very high, and the decoding operand is very big.So operational capability of directly using CPU decoding (being soft decoding) can greatly consume CPU, occupancy is often up to more than 90% during the soft solution of some older CPU, especially under the environment for use of virtual desktop, soft decoding relies on server CPU work, tends to cause the server machine of delaying so under the situation of multi-user concurrent.
And hard decoder is to rely on the video acceleration function of video card that HD video is decoded, the interior information that perhaps electric impulse signal is converted to its representative that digital coding is reduced into its representative, data etc. are enabled the support that hard solution needs video card, driving, decoder and player.
At present, each big virtual producer has agreement separately when handling multimedia, fancy price and cost performance make video card seldom be used in virtualized environment simultaneously, and therefore " hard decoder " truly is non-existent in present stage, and CPU is still in the very important effect of performance.In the face of situation like this, the utilance of Experience Degree and input cost, resource often allows the people feel contradiction.
Summary of the invention
The object of the present invention is to provide a kind of based on virtualized multimedia accelerating system, utilize computing network to handle accelerator card and cooperate and virtually carry out audio/video encoding/decoding and network packet processing etc. and accelerate in interior general-purpose computations, to improve the utilization of resources to greatest extent.
The objective of the invention is to be achieved through the following technical solutions.
A kind of based on virtualized multimedia accelerating system, comprising: virtual core layer, decoding layer, data source access layer;
The data source access layer is used for finding and accepting after the source data, through transferring to decoding layer behind the CODEC transcoding;
Decoding layer feeds back to virtual core layer processing for the form with the RTP bag after the data source access layer data decode that receives is finished;
Virtual core layer is used for request and receipt data are transmitted.
Preferably, described source data comprises files in stream media or network code stream.
The present invention compared with prior art, provided by the invention based on virtualized multimedia accelerating system, utilize computing network to handle accelerator card and cooperate the virtual audio/video encoding/decoding that carries out, improve hardware performance greatly, improved multimedia experience effect, and use simple, flexibly, can expand.

Based on virtualized multimedia accelerating system, comprising as shown in Figure 1: virtual core layer, decoding layer, data source access layer;
The data source access layer is used for finding and accepting source data (files in stream media, network code stream etc.) afterwards, through transferring to decoding layer behind the CODEC transcoding;
Decoding layer feeds back to virtual core layer processing for the form with the RTP bag after the data source access layer data decode that receives is finished;
Virtual core layer is used for request and receipt data are transmitted.
Provided by the invention based on virtualized multimedia accelerated method, utilize computing network to handle accelerator card and cooperate the virtual audio/video encoding/decoding that carries out, improve hardware performance greatly, improved multimedia experience effect, and use simple, flexibly, can expand.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
