In some embodiments, the web page main page 41 may also be a non-video playing page, such as a detail introduction page of a certain video as shown in fig. 2E. The main page of the web page shown in fig. 2E does not include a video frame. In fig. 2E, when the user presses any one of the pause key, the start key, the fast forward key, the fast rewind key, and the like on the control device to select the playback control function, the display device ignores the video playback control command input by the user by pressing the above key because the current home page does not include a video frame.
The video playing control method of the above embodiment implements the logic principle as follows:
when the browser loads a webpage, a JavaScript-based Player Controller module can be injected into the loaded webpage through plug-in mechanisms such as NPAPI/PPAPI and the like, the Player Controller module registers a callback interface to the browser kernel, and receives a message transmitted to the Player Controller module by the bottom layer system through the browser kernel through the callback interface. The function of the Player Controller module is to control the playing of the VIDEO in the web page through the interface of the VIDEO control of the standard HTML 5. The message of interest to the Player Controller module may be play, pause, play pause, stop, rewind, forward, etc.
As shown in fig. 3A, the browser web page loads and initializes the logic diagram of the Player Controller module, when the browser is started, the browser starts the module to load the web page, and then the browser parsing module parses the loaded web page and loads the Player Controller module. And after the webpage is analyzed, rendering the webpage by the browser rendering module, and displaying the webpage after rendering. Meanwhile, the Player Controller module recalls the registration message to the browser message processing module.
The video playing control method shown in fig. 3B is a schematic diagram of the logic principle. The key receiving module acquires a video playing pause control instruction which is input by a user through pressing a play pause key on the control device and corresponds to the play pause key, and sends the video playing pause control instruction to the command analysis module. Here, since the key receiving module may receive different play control commands, the key receiving module includes: at least one of a play instruction, a pause instruction, a play pause instruction, a stop instruction, a rewind instruction, and a fast forward instruction. The command analysis module may analyze the instructions to generate corresponding messages.
With the above embodiment, the command analysis module analyzes the video pause control command and converts the video pause control command into a play pause message. And sends the play pause message to the browser message processing module, and finally calls back to the Player Controller module. Specifically, a message interface is received through the browser, and a play pause message is sent to the browser kernel. And the PlayERController module acquires the play pause message through a callback interface of the browser kernel. And the Player Controller module controls the playing of the video element in the current webpage according to the play pause message.
Here, the control device sets the play pause function on the same key, and the Player Controller module acquires a play pause message. The playauxe message needs to be analyzed according to the state of the video element in the current webpage, and then the corresponding broadcast control operation is performed on the video element. And if the video element in the current webpage is in the playing state, the Player Controller module controls the video element in the current webpage to pause playing according to the play pause message. And if the video element in the current webpage is in a pause playing state, the Player Controller module controls the video element in the current webpage to play according to the play pause message.
Fig. 3C is a schematic diagram of a logic principle of another video playing control method. The key receiving module acquires a video playing fast forward control instruction corresponding to a Forwards key which is input by a user through pressing the Forwards key on the control device, and sends the video playing fast forward control instruction to the command analysis module. And the command analysis module analyzes the video fast forward control command and converts the video fast forward control command into a Forwards message. And Forwards messages are sent to the browser message processing module, and finally the messages are called back to the Player Controller module. Specifically, a message interface is received through the browser, and a Forwards message is sent to the browser kernel. The Player Controller module obtains Forwards messages through a callback interface of the browser kernel. The Player Controller module controls fast forwarding of the video element in the current web page according to the Forwards message.
In some embodiments, when the browser fills the Player Controller module, the Player Controller module is initialized and obtains the video tag in the non-hidden state in the current webpage. And if the video label in the non-hidden state exists in the current webpage, storing the video element corresponding to the video label to the Player Controller module. If the current webpage does not have the video label in the non-hidden state, the Player Controller module is acquired to be null. When the Player Controller module obtains the play pause message, it first determines whether the Player Controller module stores a video element. And if the video element is stored in the Player Controller module, controlling the video element to pause playing. If no video element is stored in the Player Controller module, the processing of the pause message is skipped. If the video element is not stored in the Player Controller module, it indicates that the current web page does not have any action related to video playing, for example, the web page with plain text does not have a video frame.
Here, since the content contained in the web page may change over time (for example, the current web page does not have an action related to video playing at a certain time, and an action related to video playing occurs after the user refreshes the web page), the Player Controller module needs to retrieve a video tag in a non-hidden state in the current web page each time the user presses a key related to video playing control on the control device.
In the above embodiment, a video playing control instruction corresponding to a key input by a user by pressing the key on the control device is obtained, and the playing of the video element in the current webpage is controlled according to the video playing control instruction. When the user needs to control the video playing in the webpage, the focus does not need to be moved to the control. The expected video playing control effect can be achieved only by pressing the corresponding video playing control key on the control device, the operation is simple, and the user experience degree of the video playing control is improved.
