Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart of a video delivery method according to an embodiment of the present disclosure. As shown in fig. 1, the video delivery method includes the following steps:
102, generating a control interface image according to information of at least one video source connected currently;
in this step, the generated control interface image is used to receive a control instruction sent by the user through a reverse control operation, and the corresponding control instruction is used to control switching of the video delivery source, selection of the video delivery source, delivery, suspension, termination, and the like of the video delivery source.
In one embodiment, generating the control interface image according to information of the currently connected at least one video source includes:
at the initial stage of video delivery, generating a control interface image according to the information of at least one currently connected video source; or the like, or, alternatively,
in the video delivery process, a request for generating a control interface image sent by a receiving terminal with master control authority is obtained, and the control interface image is generated according to the request for generating the control interface image sent by the receiving terminal with master control authority.
In this embodiment, the control interface image may be generated automatically by the sending end and sent to the receiving end at the initial stage of video delivery, where the connection is established but the delivery source is not determined; or, the control interface image may be generated by the sending end by triggering a user-defined shortcut key when the receiving end with the master control authority needs to control the release source in the video release process.
in this step, according to a specific setting, the control interface image can be selected to be sent to one or all of the plurality of receiving terminals.
In one embodiment, sending the generated control interface image to the receiving end comprises:
when the generated control interface image is sent to a receiving end, the receiving end is the receiving end with the master control authority to the control interface image;
and when the generated control interface image is sent to all the receiving ends, the master control authority is transferred among all the receiving ends by setting a master control authority preemption mechanism.
In this embodiment, if it is set to send the generated control interface image to one receiving end, the control interface image may be sent to the receiving end having the master authority. The receiving end with the master control authority can be specified in advance, and the information of the receiving end is notified to the sending end or written into the storage unit of the sending end, so that after the sending end is connected with all the receiving ends, the receiving end with the master control authority can be distinguished, and then the generated control interface image is sent to the receiving end. The receiving end can select, switch and perform other operations on the delivery source. And the receiving end without the master control authority displays a default picture before the video delivery is not carried out by the delivery source.
If the generated control interface image is set to be sent to all the receiving ends, only the receiving end with the master control authority can operate the control interface image, that is, the sending end can filter the operations of other receiving ends, and only the operation executed by the receiving end with the master control authority can be executed. In this scenario, a master control right preemption mechanism may be set to implement the transfer of control rights.
In one embodiment, as shown in fig. 2, when the generated control interface image is sent to all the receiving terminals, implementing transfer of the master control authority between all the receiving terminals by setting a master control authority preemption mechanism includes:
and step 204, if the current receiving ends have the receiving ends with the master control authority, forwarding the master control authority switching message to the receiving ends with the master control authority.
In this embodiment, a default switching combination key needs to be set, such as: setting a Ctrl + Shift + F6 combined key as an application master control authority, a Ctrl + Shift + F7 combined key as a abandoning master control authority, and a Ctrl + Shift + F8 combined key as a rejection master control request.
When the sending end receives the combined key message sent by a certain receiving end, the sending end checks whether the receiving ends with the master control authority exist in all the current connecting receiving ends, and if not, the receiving ends applying for the master control obtain the master control authority. If the receiving end with the master control authority exists, the message applying for master control is forwarded to the receiving end with the master control authority by the sending end. At this time, the user may be reminded that there is another user who wants to apply for the master control right in some hardware or software manners, for example, a manner that an indicator lamp on the receiving end is changed by blinking or a state prompting small window is operated by the sending end may be used, and a specific implementation manner may be set according to actual needs, which is not limited in this disclosure. After the master control receiving end user sees the switching request, the user can choose to give up the current master control authority or refuse the master control switching request. When the abandoning master control is carried out, the receiving end applying for the master control obtains the master control right, the sending end does not filter the control data of the sending end, and meanwhile, the receiving end abandoning the master control is brought into a filter list; when the master control switching request is rejected, the receiving end applying for master control fails to acquire the master control right.
In an embodiment, as shown in fig. 3, if there is a receiving end with master control authority in the current receiving ends, the method further includes:
and step 304, if the message returned by the receiving end with the master control authority is the master control authority switching refusal, determining not to distribute the master control authority to the receiving end which sends the master control authority switching message.
In this step, after receiving the image of the control interface, the receiving end with the master control authority can operate the image of the control interface based on a reverse control mode, and after being received by the sending end, the corresponding operation is executed at the sending end, so that switching of the delivery source, selection of the delivery source, delivery, suspension, termination and the like of the delivery source are realized.
During specific implementation, the sending end can always keep service connection with all the releasing sources, or only keep service connection with the releasing source selected by the current user; in these two cases, the sending end responds to the control command of the receiving end with the master control authority in different ways. The difference is that when the sending end keeps service connection with all the releasing sources all the time, and when the releasing sources are switched or selected, the sending end only needs to collect, encode and send the images of the corresponding releasing sources to the receiving end, and stops collecting the images of other releasing sources; when the sending end only keeps service connection with the releasing source selected by the current user, when the user switches the releasing sources, or selects one releasing source, the sending end needs to disconnect the connection (if any) with the current releasing source and establish service connection with the releasing source selected by the user, then the image is collected and coded from the corresponding releasing source, and the coded image is sent to the receiving end.
And 104, receiving a control instruction sent by a receiving terminal with the master control authority, and performing corresponding operation according to the control instruction.
Preferably, the receiving end may send the control instruction to the sending end through a preset shortcut combination key, in addition to sending the control instruction to the sending end based on the reverse control of the control interface image.
