The above technical solutions of the embodiments of the present invention are described in detail below with reference to application examples:
the application example of the invention aims to enable the anchor to be live in a plurality of live broadcast platforms at the same time.
As shown in fig. 1, for example, in a terminal device a, after a live application App1 in the terminal device a is started, if an operating system of the terminal device a is Android, a Camera Service in the Android operating system is CameraService, after App1 establishes a connection with a Camera Service in the Android operating system of the terminal device a, the Camera device of the terminal device a is started through the CameraService, and an image is previewed in real time through the Camera device; storing the real-time Preview data of the real-time Preview image into a preset Preview Buffer area, such as a Preview Buffer, through a Camera Service, and sending the real-time Preview data stored in the Preview Buffer to an App1 through the Camera Service; app1 displays a live preview image in a corresponding window interface of App1 according to the received live preview data; subsequently, if it is monitored that the live application programs App2 and App3 are connected with the Camera Service, acquiring real-time Preview data from the Preview Buffer through the Camera Service, and respectively sending the real-time Preview data to App2 and App 3; app2 and App3 display live preview images in respective corresponding window interfaces of App2 and App3 according to the respective received live preview data. The predetermined preview buffer may be a preview buffer in an operating system, or may be a preview buffer created by a developer, which is not limited herein.
In a preferred embodiment, before the first application establishes a connection with a camera service of an operating system, the method includes: starting a camera service of an operating system and establishing connection between the camera service and camera equipment; the method comprises the steps of establishing connection between a first application program and a camera service of an operating system after receiving a request of establishing connection between the first application program and the camera service of the operating system, wherein the request is sent by the first application program.
For example, in a terminal device a, an operating system of the terminal device a is Android, and after the terminal device a is started, a Camera Service of the Android operating system is started, and a connection between the Camera Service and a Camera device of the terminal device a is established; and after receiving a request for establishing connection with the Camera Service, which is sent by the live application App1, establishing connection between the App1 and the Camera Service.
In a preferred embodiment, after it is monitored that at least one second application program is connected to the system camera service, the step 104 acquires the real-time preview data from the predetermined preview buffer through the camera service, and respectively sends the real-time preview data to the at least one second application program, including: monitoring a connection state of the camera service, and after the first application program is connected with the camera service, acquiring the real-time preview data from the preset preview buffer area through the camera service and copying at least one piece of real-time preview data if at least one second application program is monitored to be connected with the camera service; and respectively sending the copied at least one piece of real-time preview data to the at least one second application program through the camera service.
For example, in the terminal device a, an operating system of the terminal device a is Android, a connection state of CameraService is monitored, after a connection between a live application App1 and CameraService is established, if it is monitored that the live application App2 and App3 are connected with CameraService, then real-time Preview data is obtained from a predetermined Preview Buffer, such as Preview Buffer, through the CameraService, and two pieces of real-time Preview data are copied; and respectively sending the copied two pieces of real-time preview data to App2 and App3 through Camera Service. Referring to fig. 3, a schematic flow chart of acquiring live preview data by each application program is shown.
In a preferred embodiment, the method further comprises: according to the started application program window component Activities of each application program, a plurality of Task stacks Task corresponding to each Activities are created; and sequentially determining the Activity corresponding to each application program as the Activity of the system main window based on the created tasks at a preset frequency so as to sequentially display the respective pictures of the windows.
For example, in the terminal device a, an operating system of the terminal device a is Android, and Task stacks Task corresponding to the Activity of App1, Task corresponding to the Activity of App2, and Task corresponding to the Activity of App3 are created according to the Activity of application window components App1, App2, and App3 that have been started; subsequently, based on the two created tasks, repeatedly and sequentially determining the activities corresponding to App1, App2 and App3 as the activities of the system main window within each minute at a predetermined frequency, such as 10 times per minute, so as to sequentially display the respective screens of the multiple windows. It should be noted that, on one hand, the selection of the user can be received according to the different requirements of the user, and the window picture of any application program can be determined to be watched; on the other hand, the display mode of the window interface of each application program may be based on the multi-window technology of the Android sound, and the display mode is performed in a picture-in-picture multi-window mode, which is not limited herein. The storage structure diagram of each Task storage Activity refers to fig. 4.
It should be noted that, as can be understood by those skilled in the art, Activity is one of the four most basic and common components in Android. Activity is an application component that provides a screen through which a user can interact in order to perform a task, and in an Android application, an Activity is typically a separate screen on which controls can be displayed and in which the user's events can be monitored and processed in response. A Task is a container with a stack structure that contains a stack of activities, and multiple Activity instances can be placed, and an application is launched following a first-in-last-out principle, for which the system creates a Task.
Through this embodiment, through establishing a plurality of tasks, when each live application switches to the backstage, avoided the condition of live broadcast service interruption to take place, simultaneously, realized the window interface of each application of carousel in the system home window for the anchor can compromise the live broadcast effect of a plurality of live broadcast platforms simultaneously when live, thereby improved the live broadcast experience of anchor.
In a preferred embodiment, the method further comprises: monitoring the running state of each application program; and when monitoring that each application program exits the operation, closing the camera equipment through the camera service.
For example, in the terminal device a, when it is monitored that the applications App1, App2, and App3 exit the operation, the Camera device of the terminal device a is turned off by Camera Service.
By means of the method and the device for realizing live broadcast, the fact that the application programs acquire the real-time preview picture in the respective running process is guaranteed, the situation that other application programs cannot acquire the real-time preview picture due to the fact that any application program exits from running is avoided, and important precondition guarantee is provided for the fact that the anchor broadcast can be simultaneously live broadcast in a plurality of live broadcast platforms.
