Description
Technical Field
The invention relates to the technical field of video screen projection, in particular to a method for performing video screen projection by conveniently and compatibly using multiple applications.
Background
With the popularization of intelligent mobile devices, the frequency of watching videos at a mobile end is very high, but the screen of the mobile end is generally small, so that the eyesight is damaged for a long time. Currently, the video of the mobile phone can be projected to a television for playing through a DLNA protocol. However, many video software do not provide the screen projection function, mainly because each application needs to do the screen projection function with time and cost.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide a method for video screen projection by being convenient and compatible with multiple applications, only one application which is specially responsible for screen projection needs to be installed at a mobile terminal, and when an external application needs to project a screen, only data capable of projecting the screen needs to be simply transmitted to the application, so that the screen projection function can be quickly realized.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for video screen projection by being convenient and compatible with multiple applications comprises the following specific processes:
s1, installing a screen projection application in the mobile equipment, wherein the screen projection application is used for projecting a video to be projected by an external application installed in the mobile equipment into the screen projection equipment; a screen projection service is developed in the screen projection application;
s2, when the external application in the mobile equipment needs to perform video screen projection, screen projection data are transmitted to the screen projection application, and the screen projection data comprise screen projection types and screen projection contents; the screen projection service of the screen projection application judges whether the screen projection service is a supported screen projection type according to the screen projection type transmitted by the external application, if so, a screen projection equipment selection interface is started, screen projection equipment capable of projecting screens is searched and displayed on the screen projection equipment selection interface, a user automatically starts the screen projection interface after selecting the screen projection equipment, and the screen projection application starts to project screen projection contents to the selected screen projection equipment.
Further, in the method, the screen projection types supported by the screen projection application include url, live and vid.
Further, in the method, the screen projection application realizes screen projection based on a DLNA screen projection protocol.
Further, in the method, if a plurality of screen-casting contents need to be subjected to screen casting, the external application sequentially transmits corresponding screen-casting data to the screen-casting applications, the screen-casting service generates a queue from first to last according to the transmission time of the screen-casting data, and after one screen-casting content is subjected to screen casting, the next screen-casting content is automatically subjected to screen casting until all screen casting is finished or the user manually exits.
The invention has the beneficial effects that: by utilizing the invention, the screen projection requirements of each application of the mobile terminal can be realized only by installing one screen projection application in the mobile terminal without developing the screen projection function of each application, and the invention is easy to realize and strong in practicability.
Detailed Description
The present invention will be further described below, and it should be noted that the present embodiment is based on the technical solution, and a detailed implementation manner and a specific operation process are provided, but the protection scope of the present invention is not limited to the present embodiment.
The embodiment provides a method for video screen projection by being convenient and compatible with multiple applications, which comprises the following specific processes:
s1, installing a screen projection application in the mobile equipment, wherein the screen projection application is used for projecting a video to be projected by an external application installed in the mobile equipment into the screen projection equipment; and screen projection service is developed in the screen projection application.
The types of projection supported by the projection application may include url, live, vid, etc. Wherein url is the most common screen projection mode, and is a video playing address; live is live screen projection; vid is a specially customized playback format. And screen projection types, various self-defined formats and the like can be continuously increased according to needs, so that screen projection compatibility is continuously enhanced.
It should be noted that the screen projection application implements screen projection based on the DLNA screen projection protocol.
S2, when the external application in the mobile equipment needs to perform video screen projection, screen projection data are transmitted to the screen projection application, and the screen projection data comprise screen projection types and screen projection contents; the screen projection service of the screen projection application judges whether the screen projection service is a supported screen projection type according to the screen projection type transmitted by the external application, if so, a screen projection equipment selection interface is started, screen projection equipment capable of projecting screens is searched and displayed on the screen projection equipment selection interface, a user automatically starts the screen projection interface after selecting the screen projection equipment, and the screen projection application starts to project screen projection contents to the selected screen projection equipment.
In the method, the screen projection service is used for receiving screen projection data of an external application and processing logic of a screen projection process, so that the screen projection can be processed in a background, and a foreground interface only needs to display corresponding screen projection information, such as screen projection name, progress, state and the like.
It should be noted that the screen-shot content may be a file name (vid type), url (url type), and a live stream address (live type) according to the screen-shot type.
Further, in the method, if a plurality of screen-casting contents need to be subjected to screen casting, the external application sequentially transmits corresponding screen-casting data to the screen-casting applications, the screen-casting service generates a queue from first to last according to the transmission time of the screen-casting data, and after one screen-casting content is subjected to screen casting, the next screen-casting content is automatically subjected to screen casting until all screen casting is finished or the user manually exits. This can satisfy some continuous broadcasting requirements.
Various corresponding changes and modifications can be made by those skilled in the art based on the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
