Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the description of the present application, it should be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or number of technical features indicated. Thus, a feature defining "a first", "a second", etc. may explicitly or implicitly include one or more such feature. In the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.
Firstly, the application can provide application scenes, such as synchronous playing of files to a host computer and other distribution machines of a video conference system through the distribution machines.
First embodiment of the present application:
please refer to fig. 1-3.
As shown in fig. 1, this embodiment provides a file synchronous playing method for video conferences, which at least includes the following steps:
s1, actively mounting a matched machine which needs to be accessed to a host through the host, summarizing all file lists mounted in the matched machine of the host into a file total list, and sending the file total list to each matched machine through the host to serve as a current remote file list of each matched machine.
In a preferred embodiment, the active mounting of the host through the host requires accessing the host, specifically:
the host computer adopts a Samba or NFS mode to mount the file system of the distribution machine to the local system of the host computer;
and mounting the provided file total list of the host to the remote file list corresponding to each host through the host.
Specifically, for step S1, mainly the file list synchronization process, as shown in fig. 2, includes two parts of file list synchronization of the host and the slave. For the host part, firstly, a host (such as a tablet computer) accessed to the host is actively mounted; and providing Samba/NFS service, allowing a platform accessed to the host to mount, mounting the file system of the slave to the host locally by means of Samba or NFS, and integrating the file lists of all the slave mounted to the host locally into a total list, and providing the total list to each slave in the video conference system.
For the machine matching part, samba\NFS service is also provided, so that the host is used for mounting and actively mounting the file list and the current remote file list provided by the host. The file list of each machine in the system is synchronized, and even if a network cannot be directly connected, the effect of sharing files in the whole video conference system can be achieved.
For samba\nfs service, the file system is based on network access, that is, an operating system interface is used to access a file of another device through a network, so for a host, a usb disk directory a on a host (tablet computer) needs to be associated with a local directory B of the host, and an application program on the host operates the file in the directory B, which is equivalent to operating the usb disk directory a on the tablet computer. Generally, the current kernel of the operating system supports Samba and NFS services, and an application program needs to specify a local directory and acquire a shared directory which is wanted to be mounted on the device.
S2, after the host receives the first distribution machine to initiate the play control request, searching a file to be controlled corresponding to the play control request in the file total list through the host, and sending the play control request to other distribution machines through an RPC remote calling mode.
In a preferred embodiment, after the host receives the first play control request from the first slave, the method further includes:
and the first slave machine sends a notification for initiating the play control request to the host machine in an RPC remote calling mode.
Specifically, for step S2, when the first accessory initiates a play or control request, the first accessory calls and notifies the host through the RPC remote call mode, searches the corresponding file in the file list of the host, and also notifies the request to other accessory terminals through the RPC remote call mode.
As shown in fig. 3, the present embodiment provides a flow chart of the file synchronous playing principle.
In a specific embodiment, all accessories are connected to a host through a network, a multimedia file list is transferred through the host, and file list data exchange is carried out between the samba server and different accessories; in the whole system, any one terminal can access the file list of other devices. When one terminal plays, the host is told to play, and the host notifies each other terminal to enter a play state. When any terminal performs fast forward or fast backward operation, the host also tells other terminals to perform the same operation.
Wherein the RPC remote invocation essentially exchanges data between two devices on the network via the TCP/UDP protocol, i.e. when there are two devices A, B, the network is interworking. The purpose of calling Interface1 on device A and responding Interface1 call on device B can be achieved by defining RPC Interface and data structure between A and B. The remote invocation of RPC can conveniently realize state notification and data exchange between A, B through a network. The ProtoBuf of Thrift, google with Apache is realized by using a relatively wide RPC at present, the specific realization of the RPC is not limited in the embodiment of the application, and the notification and the data synchronization among different devices are realized by using the technology.
And S3, after the other distribution machine receives the play control request, searching a file to be controlled corresponding to the play control request in a remote file list corresponding to the play control request, sending a play control instruction to a play system corresponding to the other distribution machine, and sending a play state to the host machine in an RPC remote calling mode after corresponding play service processing.
Specifically, for step S3, after the other slave machines receive the play control request sent by the first slave machine and forwarded by the host machine, the slave machine searches a remote file list of the slave machine for a file to be played or controlled, notifies the file to be played or controlled to a play system of the slave machine, and after performing corresponding service processing, invokes and notifies the play state to the host machine of the video conference system in an RPC remote invoking mode.
S4, after the host receives the playing states of the distribution machines, the corresponding final states are recorded, and the synchronous playing of the files is carried out through the playing system of the host according to the playing operation of the first distribution machine.
Specifically, for step S4, after the host receives the playing states of each slave machine, the final state is recorded, and the playing system of the host is called to play, and meanwhile, the final playing state is fed back to the operation initiating terminal (the first slave machine), so that the playing state of the whole video conference system is synchronized.
In a preferred embodiment, before the host receives the first play control request initiated by the first slave, the method further includes:
when the first distribution machine detects that the U disk is accessed, the operation system of the first distribution machine acquires a U disk root directory A, and sends a U disk access notification and path information to a host by adopting an RPC remote calling mode;
after the host receives the USB flash disk access notification, a corresponding path is allocated and created according to the path information, an operating system interface is called according to the path to complete the mounting association of the USB flash disk files of the first accessory, and the catalog and the file list of the USB flash disk are obtained.
In a preferred embodiment, before the host receives the first play control request initiated by the first slave, the method further includes:
when any machine is detected to be connected with the USB flash disk, the USB flash disk root directory A is obtained through the machine connected with the USB flash disk, and the remote RPC calling mode is adopted to send the USB flash disk access notification and the path information to the host.
Specifically, when any of the auxiliary machines is started, a Samba/NFS service is started, whether equipment is plugged or not is detected through an operating system of the auxiliary machine, and if so, whether the U disk is accessed or not is detected; when the access to the USB flash disk is detected, an accessible USB flash disk root directory A is obtained through an operating system interface, the accessory informs a host of the access to the USB flash disk, and simultaneously informs a host of a path through an RPC interface; after receiving that a new USB flash disk is accessed to a host, the host allocates and creates a local directory slave1 for mapping the USB flash disk directory of the host; an operating system interface is called to finish the mapping of the catalog slave1 and the distribution machine catalog A, namely, the path of the distribution machine is connected with the mounting association by utilizing a Samba/Nfs interface of the operating system; and finally, an operating system interface traversal directory slave1 is called, all files of the U disk of the slave machine are traversed, and a file list UST-1 is obtained.
In a preferred embodiment, before the host receives the first play control request initiated by the first slave, the method further includes:
when the host is detected to be connected to the USB flash disk, the corresponding paths are distributed and created for the USB flash disk file through the host, and the paths of the various distribution machines are associated in a mounting mode through an operating system interface.
Specifically, when a video conference system is accessed to one SLAVE machine, a host machine can acquire a file LIST, and all the SLAVE machine file LISTs are assembled into a SLAVE file LIST-SLAVE; meanwhile, when the host accesses the USB flash disk, the catalog and the file LIST of the USB flash disk are obtained through an operating system interface, and all the file LISTs of the USB flash disk directly connected to the host are assembled into a host file LIST LIST-MASTER; and finally, integrating the SLAVE file LIST with the host file LIST-MASTER to form a file total LIST, providing the file total LIST to each SLAVE machine which is accessed to the video conference system and serving as a remote file LIST of each SLAVE machine, so that when the SLAVE machine plays and synchronizes files through the host machine, the SLAVE machine can directly search the corresponding files to be played or controlled in the remote file LIST.
In a preferred embodiment, the processing of the playing service in the step S3 specifically includes:
inquiring whether the player of the distribution machine can play the control program of the distribution machine or not through the player of the distribution machine;

after the control program of the host receives the synchronous play starting notification sent by the control program of the slave machine, judging the state of the host to determine whether synchronous play can be performed or not, and if not, sending a play failure notification to the slave machine;
if yes, converting the playing path into a host playing path according to the playing control instruction, and informing a player of the host to synchronously play.

and after the player of the host computer judges that synchronous playing can be started, returning the set playing result to the distribution machine so that the control program of the distribution machine updates the playing information according to the playing result and updates the playing state of the host computer.
Specifically, firstly, inquiring whether the video can be played or not to a distribution machine control program by controlling a player in a distribution machine of an initiating terminal, and returning the play state to the distribution machine player by the distribution machine control program when the host in the video conference system is in a play state; after the player of the distribution machine starts to play, the distribution machine control program records the relevant data such as the playing state, the type and the like, and informs the host to start playing; the host control program queries the state of the host computer and determines whether the host computer can play the host computer; if the playing is judged to be unable to be played, notifying a playing failure and a result to a distribution machine of the control initiating terminal; if the video can be played, converting the path into a local path according to the playing control request and the playing file information, and informing the host player of entering a playing state, and likewise, judging whether playing is carried out or not and judging the layout or other operations of the video to be prepared for playing; when the inside of the host player judges that the playing can be started, the set playing result is sent to a host control program, and the host control program returns the playing result and updates playing information such as fast forward, zoom ratio and the like; the control program of the distribution machine updates the current playing state of the host machine, and the distribution machine is completed to inform the state to the host machine through RPC call.
