[0037] The working principle of the embodiment for one-key screen recording of a video is as follows:

[0038] The embodiment is operated in a hardware combined with software mode; wherein the hardware part includes an image processing unit, a screen display terminal and a screen control terminal; the software part is all prior art, including two classes of MediaProjection and MediaCodec based on an Android system to realize. First, a MediaProjection object is obtained through a MediaProjectionManager class, and the object is used to capture video content on the screen; after obtaining user authorization, a virtual screen VirtualDisplay is created, which is used as an output buffer of screen content. Then, image data on the screen is transmitted to MediaCodec for encoding and compression, and finally a video file is generated. Similar to the Windows system, the screen recording of the Android system also needs to consider factors such as the sampling frequency, encoding format and resolution of the image, to ensure the video quality and smoothness of the recording.

[0039] The working principle of the embodiment for the user to annotate a video through the functional circuits of the image processing unit is as follows:

[0040] When the user uses the annotation function during the screen recording process, the screen recording software creates an independent layer with multiple keys on the screen, which corresponds to the functions of the circuits of the image processing unit, and is used to display the content of the annotation; the layer is located above the screen image and does not affect the original content of the screen image. The user performs annotation operation on the screen, such as drawing lines, adding text, using graphic tools, etc., and the software records the operation track and input text information of the user in real time, and converts the information into graphic data and displays it on the annotation layer; the specific processing and operation are performed by the functional circuits.

[0041] For example, when the user draws a straight line on the screen by using a mouse or touch, the software records the moving track of the mouse or touch, and then draws a corresponding straight line on the annotation layer.

[0042] Data storage and transmission: the annotated graphic data is stored and transmitted together with the video data of the screen recording (stored in the storage circuit). During storage, the annotation data is embedded in the video file and becomes part of the video. In this way, when playing the screen recording video, the annotation content is displayed together with the screen image.

[0043] During transmission, if it is a live screen recording, the annotation data is transmitted together with the video data through the network to the server, and then distributed to the audience's device for playing. If it is a local recording and sharing of the video file, the annotation data is packaged together with the video data into a file, so that the annotation content can be correctly displayed when playing on other devices.

[0044] In summary, the one-key recording and annotation device provided by the present application sets up an image processing unit, a screen display terminal and a screen control terminal that work together. Through the improvement of the circuit structure of the image processing unit, the operation process is greatly simplified by the mutual cooperation between the circuits, so that the physical keys provided on the screen display terminal in cooperation with the image processing unit can be conveniently operated to start, pause, stop and the like. The present application can be widely applied to the manufacture of interactive video image processing equipment. The present application sets up a plurality of recording key modules corresponding to each functional circuit, and the physical keys have one-key recording function. The user only needs to click one button to start or end the video recording work, so that the video recording is efficient and fast, and the recording work can be easily completed without professional screen recording knowledge or skills.

[0045] The one-key recording and annotation device provided by the present application can be a smart phone or a smart tablet with a capacitive touch screen, or a capacitive touch screen matched with an LED display and attached to the surface of the LED display screen. It can be operated on multiple screens, and it is more convenient to add text, shapes and the like in the video to explain and describe the video content. The use of multiple control ends in the combination of recording and annotation greatly improves the work efficiency of video production, optimizes the user experience, improves the user satisfaction, and promotes the interaction and communication between the user and the platform.
