It should be noted that, most of the existing pip playing methods are: when the picture-in-picture playing is required, the picture-in-picture player acquires picture-in-picture video data to play and displays the picture-in-picture video data on a page in a picture-in-picture mode, then the picture-in-picture player is directly closed when the picture-in-picture playing is not required, and when the picture-in-picture playing is required to be started again, the picture-in-picture player is restarted to acquire the picture-in-picture video data again.
In step S1 of the embodiment of the present invention, a MediaPlayer manager is first created, and the MediaPlayer manager is used to manage MediaPlayer, and when the operation is specific, a MediaPlayer member variable may be set in the MediaPlayer manager, which is used to correspond to MediaPlayer, and the MediaPlayer manager has built-in getInstance () method, and has built-in common methods related to MediaPlayer, such as: initializing a MediaPlayer, playing stream address acquisition, pausing play, stopping play, destroying MediaPlayer, and listening to MediaPlayer, etc.
Wherein getInstance () is a function with which instances of classes can be created in java using singleton schema, i.e., the MediaPlayer manager can create MediaPlayer with getInstance ();
the MediaPlayer is used as a media player of an Android system, provides functions such as playing, pausing, stopping, setting a monitor and the like of network video, and a MediaPlayer manager secondarily packages the functions, so that the MediaPlayer is prevented from being directly operated from the outside, all operations of the MediaPlayer are ensured to be synchronously executed in HandlerThread, and asynchronous operation is avoided.
In step S2, the live broadcast room is opened, and when video playing is performed in the live broadcast room, the live broadcast room sends an HTTP request data stream address, at this time, a MediaPlayer manager is used to initialize a MediaPlayer, obtain a live broadcast video data stream address, perform background parsing using the MediaPlayer, and initialize an Activity component while the MediaPlayer loads a video data stream;
initializing the Activity component, specifically: when a user opens a live broadcast room, namely opens an Activity component, the Activity component as a component of the Android system can actively call methods such as onCreate (), onStart (), onResume (), and the like in sequence, the onCreate () as the first method for initializing and calling the Activity component can perform some initialization operations inside, for example, a view is created and displayed on the Activity component, Surface used by the MediaPlayer is generated in the view, and the interface is presented to the user after the onResume () call is completed;
while onCreate (), onStart (), onResume () are all common functions;
onCreate () is a special function in Android to "represent that a window is being generated", which does not produce a window, but sets the properties of the window such as style, position color, etc. before the window is displayed;
onResume () is used to get the user focus for the Activity component and then interact with the user;
onStart () is used to launch an Activity component;
in step S3, based on the Activity component, a first Surface window is created by using the textview control and the Surface texture control, where the first Surface window is used for performing picture output during background parsing of the MediaPlayer, that is, displaying a video played by the MediaPlayer and performing picture output, and visually, a video picture displayed by the first Surface window is a video played by the MediaPlayer.
The operation step of playing the live video in the live broadcast room, and then in step S4, the operation of playing the live video in picture-in-picture is started:
in step S4, when it is necessary to start picture-in-picture play, closing the first Surface window, and creating a second Surface window by using WindowManager, where the second Surface window is used to display the live video data analyzed by MediaPlayer in picture-in-picture form, and it should be noted that, although the first Surface window is closed, the operation of MediaPlayer acquiring and analyzing the live video data is not stopped but continuously performed, but only the background analysis of the picture-in-picture video data is performed by the picture-in-picture player at this time, that is, only the first Surface window is closed, and the image display is not performed by using the first Surface window, but the second Surface window is used to display the live video data analyzed by MediaPlayer in picture-in picture form;
then, in step S5, when the picture-in-picture playing operation is stopped, the second Surface window is closed, the first Surface window is created again based on the Activity component, and the live video data analyzed by the MediaPlayer is displayed;
it should be noted that, in step S4, only the display operation of the first Surface window is stopped, and the analysis operation of the live video data of the MediaPlayer is not stopped, so that when the picture-in-picture video display is needed again in the following, the live video data still analyzed in the background is directly displayed without restarting the player or re-acquiring the live video data;
therefore, when the live video playing needs to be carried out in the picture-in-picture playing, the embodiment of the invention has the advantages that the video playing and the video displaying of the live video are independent, and the background continuously analyzes the live video data in the switching process of the two display windows, so that the playing smoothness during the picture-in-picture playing is ensured, and the guarantee is provided for the video watching of a user.
In an embodiment of the present invention, the method further comprises the steps of:
when the next picture-in-picture playing work is needed, initializing the WindowManager again, and recreating the second Surface window based on the WindowManager;
that is, before the next picture-in-picture play operation, if there is no other control command, the MediaPlayer continues to perform analysis in the background, that is, video play, but does not perform display, but actually, an operation of restarting the first Surface window to perform display is performed, and when the next picture-in-picture play operation is required, video display is performed again through the second Surface window, that is, windows manager is initialized again, and the second Surface window is created again based on windows manager.
It should be noted that, in the embodiment of the present invention, creating the first Surface window based on the Activity component specifically includes the following steps:
creating a surfaceTexture control in the Activity component by using a TextureView control;
a first Surface window is created using a Surface texture control.
The MediaPlayer manager is used for controlling the MediaPlayer to perform initialization, pause, stop, destroy, monitor and play.
Further, in the embodiment of the present invention, a handler thread is configured in the MediaPlayer manager, and is used for executing all operations of the MediaPlayer manager, so as to avoid blocking the UI thread;
namely, the MediaPlayer manager performs operations given by the MediaPlayer manager for the MediaPlayer by HandlerThread at the time of initializing, pausing, stopping, destroying, listening, and playing the MediaPlayer.
Based on the same inventive concept, the application provides another picture-in-picture playing method in the live broadcast room corresponding to the embodiment, which is detailed in the embodiment two.
