Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the description of the present application, it is to 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 relative importance or implying any number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless otherwise specified.
First, the application scenario that the present invention can provide is introduced, such as synchronous playing of files between a host and other machines of a video conference system through the machines.
The first embodiment of the present invention:
please refer to fig. 1-3.
As shown in fig. 1, the present embodiment provides a file synchronized playing method for a video conference, which at least includes the following steps:
s1, actively mounting the matched machine needing to be accessed to the host machine through the host machine, summarizing all the file lists mounted in the matched machine of the host machine into a file total list, and sending the file total list to each matched machine through the host machine to be used as a current remote file list of each matched machine.
In a preferred embodiment, the active mount of the host computer to be accessed to the machine allocation machine specifically includes:
the host mounts the file system of the machine allocation into a local system of the host in a Samba or NFS mode;
and sending the file total list provided by the machine-mounted host computer to a remote file list corresponding to each machine-mounted host computer.
Specifically, as for step S1, the process of file list synchronization is mainly performed, and as shown in fig. 2, the process includes file list synchronization of the host and the machine. For the host part, firstly, a matched machine (such as a tablet computer) which is accessed into the host is actively mounted; and providing Samba \ NFS service, mounting a platform accessed to the host, mounting a file system of the matched machine to the local host in a Samba or NFS mode, and aggregating file lists of all matched machines mounted to the local host into an overall list to be provided to each matched machine in the video conference system.
And for the machine matching part, the Samba \ NFS service is also provided, the host is enabled to mount, and the file list provided by the host and the current remote file list are actively mounted. The file list of the local machine allocation is provided to the host for gathering through the Samba/NFS service, and all the file lists in the whole system are mounted to the remote file list of the local machine allocation machine through the Samba/NFS service provided by the mounting host, so that the file list synchronization of each machine allocation machine in the system is realized, and the effect of sharing files in the whole video conference system can be realized even if the network cannot be directly connected.
For the Samba \ NFS service, the file system is essentially based on network access, that is, an operating system interface can be used to access a file of another device through a network, so for the host, the usb disk directory a on the computer (tablet) connected to the host needs to be associated with the local directory B of the host, and the 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. Generally, the kernel of the current operating system supports Samba and NFS services, and what an application program needs to do is to specify a local directory and obtain a shared directory to be mounted to a device.
And S2, after the host receives a play control request initiated by a first machine, searching a file to be controlled corresponding to the play control request in the file general list through the host, and sending the play control request to other machines through an RPC remote call mode.
In a preferred embodiment, after the host receives the play control request initiated by the first machine, the method further includes:
and the first machine allocation machine sends a notice for initiating a play control request to the host machine in an RPC remote call mode.
Specifically, for step S2, when the first accessory initiates a play or control request, the RPC remote call mode is used to call and notify the host, the host searches for a corresponding file in the local file list, and the RPC remote call mode is also used to notify the request to other accessory terminals.
As shown in fig. 3, this embodiment provides a flowchart of the principle of file synchronized playing.
In a specific embodiment, all accessories are connected to a host through a network, a multimedia file list is transferred through the host, and a samba server is utilized to exchange file list data with different accessories; in the whole system, any terminal can access the file list of other equipment. When one terminal plays, the host is informed to play, and the host informs each other terminal to enter a playing state. When any terminal carries out fast forward or fast backward operation, the host tells other terminals to carry out the same operation.
Where RPC remote invocation essentially exchanges data between two devices over a network via the TCP \ UDP protocol, i.e., when two devices A, B exist, the networks are intercommunicated. 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 status notification and data exchange between A, B through the network can be conveniently realized through RPC remote call. Currently, wider RPCs are used to implement the swift of Apache and the ProtoBuf of Google, and in the embodiment of the present invention, the specific implementation of RPCs is not limited, and only this technology is used to implement notification and data synchronization between different devices.
And S3, after the other machines receive the playing control request, searching the files to be controlled corresponding to the playing control request in the corresponding remote file list, sending playing control instructions to the playing systems corresponding to the other machines, and after corresponding playing service processing is carried out, sending the playing state to the host through an RPC remote calling mode.
Specifically, in step S3, after the other matching machines receive the play control request sent by the host machine for forwarding the first matching machine, the file to be played or controlled is searched in the remote file list of the local matching machine, and the file is notified to the play system of the local matching machine, and after the corresponding service processing is performed, the play state is called and notified to the host machine of the video conference system in an RPC remote call manner.
And S4, recording the corresponding final state after the host receives the playing state of each machine, and synchronously playing the file according to the playing operation of the first machine through the playing system of the host.
Specifically, in step S4, after the host receives the play status of each match machine, the host records the final status, calls the play system of the host to play, and feeds back the final play status to the operation initiating end (the first match machine), thereby synchronizing the play status of the entire video conference system.
In a preferred embodiment, before the host receives the play control request initiated by the first machine, the method further includes:
when the first machine matching detects that a USB flash disk is accessed, a USB flash disk packing directory A is obtained through an operating system of the first machine matching, and a USB flash disk access notification and path information are sent to a host by adopting an RPC remote call mode;
after the host receives the USB flash disk access notification, a corresponding path is distributed 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 file of the first accessory, and a directory and a file list of the USB flash disk are obtained.
In a preferred embodiment, before the host receives the play control request initiated by the first machine, the method further includes:
when detecting that any machine is connected with the USB flash disk, obtaining a USB flash disk packing directory A through the machine matching of the connected USB flash disk, and sending a USB flash disk access notice and path information to the host by adopting an RPC remote call mode.
Specifically, when any machine is started, the Samba \ NFS service is started, whether equipment is plugged or not is detected through an operating system of the machine, and if the equipment is plugged or not, whether the equipment is accessed to a USB flash disk is detected; when the USB flash disk is detected to be accessed, an accessible USB flash disk root directory A is obtained through an operating system interface, the accessory informs a host computer of the access of the USB flash disk, and meanwhile, the path is informed to the host computer through an RPC interface; after receiving that a new U disk is accessed to the computer, the host allocates and creates a local directory slave1 for mapping the U disk directory of the computer; calling an operating system interface to complete the mapping of the directory slave1 and the machine allocation directory A, namely completing the mounting association with the path of the machine allocation by using a Samba \ Nfs interface of the operating system; and finally, calling an operating system interface to traverse the directory slave1, traversing all files of the machine-matched U disk, and acquiring a file list UST-1.
In a preferred embodiment, before the host receives the play control request initiated by the first machine, the method further includes:
when the host is detected to be accessed to the U disk, the host allocates and creates a corresponding path for the U disk file, and the corresponding path is mounted and associated with each matched path through an operating system interface.
Specifically, when the video conference system is accessed to one distribution machine, the host can acquire a file LIST and assemble all distribution machine file LISTs into a subordinate file LIST-SLAVE; meanwhile, when the host accesses the U disk, the directory and the file LIST of the U disk are obtained through an operating system interface, and all the file LISTs of the U disk directly connected to the host are assembled into a host file LIST LIST-MASTER; and finally, summarizing the subordinate file LIST-SLAVE and the host file LIST-MASTER into a file total LIST, providing the file total LIST to each matched machine which has access to the video conference system, and using the file total LIST as a remote file LIST of each matched machine, so that when the host machine plays and synchronizes files of the matched machine, the matched machine can directly search corresponding files to be played or controlled in the remote file LIST.
In a preferred embodiment, the playing service processing in step S3 specifically includes:
inquiring whether the machine matching control program can be played or not through the player of the machine matching;
if so, judging the current playing state of the host through the machine matching control program and returning to the player of the machine matching so as to enable the player of the machine matching to start synchronous playing according to the current playing state of the host, and recording the playing state and type of the machine matching through the control program of the machine matching;
after the control program of the host machine receives the synchronous playing starting notice sent by the control program of the machine matching, the state of the host machine is judged to determine whether synchronous playing can be carried out, if not, a playing failure notice is sent to the machine matching;
if yes, the playing path is converted into a host playing path according to the playing control instruction, and a player of the host is informed to carry out synchronous playing.
In a preferred embodiment, the processing of the play service in step S3 further includes:
and after the player of the host judges that synchronous playing can be started, returning the set playing result to the machine allocation machine so that the control program of the machine allocation machine updates the playing information according to the playing result and updates the playing state of the host.
Specifically, whether the video can be played or not is inquired for a distribution control program by controlling a player in a distribution machine of an initiating end, the host playing state in the video conference system is currently played by the distribution control program, and the playing state is returned to the distribution player; after the machine matching player starts playing, recording related data such as playing state, type and the like through a machine matching control program, and informing a host computer of starting playing; the host control program inquires the state of the host computer and determines whether the playing can be carried out; if the player can not be played, the player is informed of the playing failure and the result to the machine allocation 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 to enter a playing state, wherein the host player needs to judge whether to play or not and judge the layout or other operations required to be prepared for video playing; when the host player judges that the playing can be started, the set playing result is sent to the host control program, the host control program returns the playing result, and the playing information is updated, such as fast forward, zoom ratio and the like; and the machine matching control program updates the current host playing state, and completes the machine matching and informs the state to the host through RPC calling.
In a preferred embodiment, in step S4, after the host receives the playing status of each machine, the corresponding final status is recorded, and the file is synchronously played according to the playing operation of the first machine through the playing system of the host, specifically:
sending the collected current playing operation and playing state of the player of the machine matching to the control program of the host through the control program of the machine matching;

and calling an operating system interface through the host to record the final operating state of the host and sending the final operating state to other machines so that the other machines update the playing state according to the final operating state in each period to finish the synchronous playing of the file.
Specifically, when a player of the distribution machine at the initiating end is controlled to perform playing operations such as amplification/fast forwarding to a distribution machine control program, the distribution machine control program judges the current state and sends the same playing operations such as amplification/fast forwarding to a host machine control program of the video conference system, and after the host machine control program judges the current state, the host machine control program sends an in-operation state notification to the distribution machine control program and notifies the host machine player to perform corresponding related operations; synchronizing the interfaces of the host player, and calling a system operation interface to operate after synchronization is completed; the host control program calls the relevant interface of the operating system, records the last operating state and the video playing progress synchronized once in each period, sends the operating result to the machine matching control program and updates the current playing state; the machine allocation control program updates the current playing state according to the operation result to complete the playing control operation; it should be noted that, in the process of synchronizing the interfaces of the host player, the host needs to perform interface synchronization on the accessed other machines (except the machine at the control initiating end) according to the operation instruction received by the host, including file operation synchronization and video schedule synchronization, so as to achieve the technical effect of performing file or video synchronous playing or control on the host and the other machines of the video conference system through any machine.
