Embodiment 1

[0056] Embodiment 1 of the present application provides a data writing method, which will be described in detail below with reference to the accompanying drawings.

[0057] see image 3 , which is a flowchart of a data writing method provided by this application. The data writing method is applied to video recording, and the method includes:

[0058] Step 301: Initialize control frames and data frames.

[0059] In a possible implementation manner, when using the OBS to record video, it is first necessary to initialize the control frame Script Tag Data, the audio data frame Audio Tag, and the video data frame Video Tag. The control frame Script TagData is used to store video duration information and video size information filesize; the audio data frame AudioTag is used to store audio data; the video data frame Video Tag is used to store video data.

[0060] After the control frame Script Tag Data is initialized, the initial values ​​of the video duration information duration...

Embodiment 2

[0076] Embodiment 2 of the present application provides a data writing system, which will be described in detail below with reference to the accompanying drawings.

[0077] see Figure 5 , which is a schematic diagram of a data writing system provided by this application. The data writing system is applied to video recording, and the system includes: a processor 501 and an input module 502 .

[0078] The processor 501 is configured to initialize a control frame and a data frame; wherein, the control frame is used to store video duration information; and the data frame is used to store audio data and video data.

[0079] The input module 502 is configured to encode the collected audio data and video data and write them into the data frame.

[0080] The processor 501 is further configured to generate current video duration information; write the current video duration information into the control frame every preset time, so as to update the video duration information stored in...

Embodiment 3

[0091] Embodiment 3 of the present application provides a terminal device, and the terminal device includes the data writing system described in Embodiment 2 of the present application.

[0092] In this embodiment, the terminal device configured with the data writing system described in Embodiment 3 of the present application can ensure that most of the content of the video file can be played normally even if an unexpected situation occurs during the video recording process, so that The video data and audio data that cannot be played normally are controlled within the preset time to reduce the impact of emergencies in the video recording project.

Abstract

The present application discloses a data writing method, system and terminal equipment, which are applied to video recording. The method includes: initializing a control frame and a data frame; wherein, the control frame is used to store video duration information; the data The frame is used to store audio data and video data; the collected audio data and video data are coded and written into the data frame; the current video duration information is generated; every preset time, the current video duration information is written into The control frame is configured to update the video duration information stored in the control frame. In the process of video recording, after an unexpected situation occurs, it can ensure that most of the content of the video file can be played normally, so that the video data and audio data that cannot be played normally can be controlled within the preset time, reducing the occurrence of unexpected events in the video recording project. The influence of development status.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a data writing method, system and terminal equipment. Background technique [0002] OBS is a software for video recording. OBS is similar to a broadcasting station and supports switching between multiple scenes. OBS can record scenes as video files in FLV streaming media format. [0003] However, during the process of using OBS to record video files, unexpected situations may occur, such as: OBS software crashes, antivirus software kills the process, or the computer system crashes. Unforeseen circumstances will cause some data in the recording process to not be written into the video file, and the following problems will occur: [0004] (1) The built-in player of Windows cannot play the recorded video files; (2) Some specific players can play the recorded video files, but during the playback process, the duration of the video files cannot be obtained and cannot...
