[detailed description of the invention]
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
Disclosure embodiment provides a kind of files in stream media control method based on cloud desktop and system, processes the excessive problem causing virtual machine card to pause of pressure of event in order to solve cloud desktop server, thus improving the user experience of cloud desktop. As it is shown in figure 1, the method comprising the steps of S10-S30:
In step slo, receive the call instruction of first terminal, this call instruction comprises the files in stream media information that needs call.
First terminal is teacher side, it is possible to being PC (PersonalComputer, personal computer), files in stream media information is stored in PC this locality, or in other storage devices can being connected with this PC, then call instruction is sent to local by PC; First terminal can also be cloud terminal, and files in stream media information is stored in cloud desktop server, then call instruction sends to cloud desktop server from the first cloud terminal.
This call instruction is to the relevant information of the files in stream media called required for containing, such as, video name, video duration, video playback initial time and end time, video type are and video playback form etc., and this files in stream media information can need storage voluntarily according to user and adjust, and can be set according to the needs of user in the first cloud terminal and select.
In step S20, call the files in stream media of correspondence according to this files in stream media information in call instruction, and according to default encoding and decoding standard, this files in stream media is carried out encoding and decoding.
When first terminal is PC, then called files in stream media by PC in this locality; When first terminal is cloud terminal, then called files in stream media by cloud desktop server at cloud desktop server.
The files in stream media called can be various different forms, carries out unified codec according to encoding and decoding standard set in advance so that the files in stream media of all different-formats becomes consolidation form after output generation. Described encoding and decoding standard set in advance can be set according to the needs of user and select.
In certain embodiments, this step S20 includes: call in this files in stream media information the files in stream media that video format is avi, flv, mov, rmvb or MP4 of record, and according to H.264 standard by files in stream media that these files in stream media encoding and decoding are H.264 form.Namely, in said process, encoding and decoding standard set in advance is H.264 standard, carry out under the standard after encoding and decoding, the files in stream media of output is all H.264 form by encoding and decoding, make output file form consistent, in order to this second cloud terminal in following steps S30 is decoded and shows.
In step s 30, this files in stream media after encoding and decoding is sent to the second cloud terminal, makes this second cloud terminal that this files in stream media after encoding and decoding is decoded and is shown. In this step S30, block the files in stream media decoding timed by originally cloud desktop server pressure being caused excessive and display process has been unloaded to this second cloud terminal and has performed, namely, by making this second cloud terminal be decoded and show, alleviate the operating pressure of cloud desktop server, thus greatly reducing the burden of cloud desktop server, and then solving the problems such as files in stream media broadcasting card, improve the user experience of cloud desktop.
In certain embodiments, as in figure 2 it is shown, also include step S40 before the step S10 of the method:
In step s 40, after logging in this first terminal by first user name set in advance and first password certification, this call instruction is sent.
In certain embodiments, when first terminal is cloud terminal (i.e. the first cloud terminal), cloud desktop server runs teacher's virtual machine (corresponding first cloud terminal), need the teacher carrying out imparting knowledge to students can be logged in by this first cloud terminal, and this login process needs to carry out the certification of username and password, obtain secret information (contents of the need for confidentiality such as such as paper) to prevent other staff from passing through after this first cloud terminal logs in. And this first user name set in advance and first password can carry out sets itself as required for each section purpose teacher. In the present embodiment, after logging in, teacher can call files in stream media as required in cloud desktop server, now selects the corresponding information of the files in stream media of files in stream media and its needs display needing to call, it is possible to send call instruction.
In certain embodiments, as it is shown on figure 3, also include step S50 before the step S10 of the method:
In step s 50, log in this second cloud terminal by the second user name set in advance and the second cipher authentication, or directly log in this second cloud terminal by authentication-exempt mode; Wherein, this second cloud terminal is one or more.
In certain embodiments, described second cloud terminal is student side. namely, cloud desktop server runs one or more student's virtual machine (corresponding second cloud terminal), need the student carrying out learning can be logged in by this second cloud terminal, and in this login process, if each student has student's virtual machine of each self-retaining, then can set that login process needs to carry out the certification of username and password, to ensure that each student can use the computer of oneself, and then ensure the safety of each self-information and the order of study, and this second user name set in advance and the second password can carry out sets itself as required for students, intelligible, if every student is all without student's virtual machine of each self-retaining, it is that random selecting learns, at this point it is possible to directly log in this second cloud terminal by authentication-exempt mode, in order to save login time, improve learning efficiency.
The said method that the embodiment of the present invention provides, by being processed by cloud desktop server under original state thus cause cloud desktop server process event pressure excessive and block time files in stream media decoding and display process be unloaded to cloud terminal perform, thus, when needs carry out the broadcasting of large-scale stream media file cocurrent, it not all of coding and the decoding process of independently being undertaken by cloud desktop server, but process display stream medium file (such as video) is decoded by cloud terminals share, so greatly reduce the burden of cloud desktop server, and then solve the problems such as files in stream media broadcasting card, improve the user experience of cloud desktop.
