Problems solved by technology

However, the existing cross-terminal screen recording generally requires that the encoder in the second terminal and the stream mixer in the first terminal be developed based on the same framework, and when the encoder in the second terminal and the stream mixer in the first terminal When developed based on different frameworks, the screen recording data synthesized by the mixed stream of the first terminal cannot be played normally
In other words, the existing cross-terminal screen recording can only be applied between terminals with the same type of encoder and mixer, and cannot be applied between terminals with different types of encoders and mixers

Embodiment 1

[0142] see Figure 4 , Figure 4 A schematic flow chart of a cross-terminal screen recording method provided in this embodiment, which can be applied to figure 2 The application scenario shown. Such as Figure 4 As shown, the method may include:

[0143] S401. The first terminal sends screen recording request information to the second terminal.

[0144] It should be understood that after the Bluetooth connection and the WiFi connection between the first terminal 100 and the second terminal 200 are successfully established, when the user needs to record the content being presented by the second terminal 200 through the first terminal 100, the user can pass The first terminal 100 sends screen recording request information to the second terminal 200, and at this time, the first terminal 100 can send screen recording request information to the second terminal 200 based on Bluetooth communication, and the screen recording request information is used to instruct the second term...

Embodiment 2

[0172] In Embodiment 1, the first terminal 100 / second terminal 200 performs the target audio data and the target audio data by searching for the corresponding relationship between the original audio structure and the target audio structure and the corresponding relationship between the original video data and the target video data. The extraction and conversion of video data, that is, the corresponding relationship between the original audio structure corresponding to different encoders and the target audio structure corresponding to different mixers needs to be configured in the first terminal 100 / second terminal 200 in advance, and different codecs need to be configured. The corresponding relationship between the original video structure corresponding to the encoder and the target video structure corresponding to different stream mixers, and when there are many types of encoders and / or stream mixers, that is, when the original audio structure, target audio structure, original ...

Embodiment 3

[0204] Such as Figure 7 As shown, in this embodiment, the MFSM module can be set in the second terminal 200 to perform the intermediate conversion of the target audio data and the target video data, and the MFSM module can be set in the first terminal 100 to convert the data obtained by the intermediate conversion into Target audio data and target video data to simplify the configuration of the corresponding relationship between the first terminal 100 and the second terminal 200, reduce the development workload and subsequent update workload of the development staff, and effectively reduce the target audio structure and target video The search time of the structure can effectively increase the conversion speed of the target audio data and the target video data, and improve the stream mixing efficiency of the stream mixer.

[0205] see Figure 8 , Figure 8 A schematic flowchart of a cross-terminal screen recording method provided in this embodiment, which can also be applie...

Abstract

The invention is suitable for the technical field of terminals, and particularly relates to a cross-terminal screen recording method, terminal equipment and a computer readable storage medium. According to the method, original audio data and original video data encoded by an encoder in a second terminal can be converted according to a target audio structure and a target video structure corresponding to a flow mixer in a first terminal, so that target audio data and target video data required by flow mixing of the flow mixer in the first terminal are obtained; therefore, the stream mixer can mix streams to obtain screen recording data which can be normally played, compatibility between encoders of different types and the stream mixer is achieved, the problem that cross-terminal screen recording cannot be applied to terminals with encoders of different types and stream mixers is solved, the application range of cross-terminal screen recording is widened, and the invention has high usability and practicability.

Description

technical field [0001] The present application belongs to the technical field of terminals, and in particular relates to a cross-terminal screen recording method, a terminal device and a computer-readable storage medium. Background technique [0002] Cross-terminal screen recording refers to the process of using the first terminal to record the screen being presented by the second terminal and saving it in the first terminal. In the current cross-terminal screen recording, the second terminal generally collects audio and video in real time for the picture it is presenting, and sends the collected audio and video to the first terminal after being encoded by an encoder in the second terminal. After the first terminal receives the encoded audio and video, it can mix the audio and video through the stream mixer in the first terminal to synthesize the screen recording data and save it in the first terminal, so that the first terminal can share the picture being presented by the s...
