Problems solved by technology

During the saving process, use the stop function of MediaRecorder to stop recording, and the driving record will stop. When calling the start function again, you need to restart the camera and other work. The driving record will not work during the period from stop to start, and will not work. This period of time usually lasts for 1–3s, and the video during this period cannot be recorded and saved
[0006] That is to say, when the driving recorder in the prior art performs video recording in the driving process, because it saves the file every once in a while, there will be a short period of time when the file is saved. The video cannot be recorded and saved, so it cannot be obtained. To a complete video recording file, it is likely to lead to the loss of key video information, which cannot meet the requirements of seamless video recording

Embodiment 1

[0052] Embodiment 1 of the present invention provides a video recording method, the process of which is as follows figure 1 shown, including the following steps:

[0053] Step S101: After the video recording starts, cache the latest video data for a specified time length.

[0054] During the driving process or other processes that require video recording, when the video recording function is activated, the cache function is also activated to cache the video data recorded in a certain period of time before the current recording moment, that is, to cache the latest video data for a certain period of time.

[0055] Step S102: When the storage period expires, according to the cached video data, determine the missing video data between the current video file saved and the next video file to be created.

[0056] Save the video data according to a certain storage period, such as 1 second, 3 seconds, 5 seconds, 8 seconds, etc. to save the video file at any selected time length. When ...

Embodiment 2

[0073] Embodiment 2 of the present invention provides a specific implementation process of the above-mentioned video recording method, which is used in the process of driving recording, and its flow is as follows figure 2 shown, including the following steps:

[0074] Step S201: Start the driving recorder.

[0075] After starting up, start the driving recorder for driving image recording.

[0076] Step S202: start video recording.

[0077] Start the recording function and start recording.

[0078] The video recording application interface set in the applications layer can be called to start the recording function, and the caching function can be started at the same time as the recording is started.

[0079] The functional interfaces for driving recording video set in the applications layer may include: video application interface Digital Video Recorder (Digital Video Recorder, DVR) and launcher / system user interface / setting (Launcher / system UI / Setting) interface.

Abstract

The invention discloses a video recording method, device and equipment. The method comprises the following steps: after video recording is started, caching latest video data of a specified time length; when the storage period expires, determining missing video data between the stored current video file and the created next video file according to the cached video data; and acquiring missing videodata from the cached video data, and supplementing the missing video data into the stored current video file or the created next video file. According to the invention, the completeness of video recording in the driving process can be ensured, the lack of video recording is avoided, the equipment power consumption is not increased, and the effect of saving more electricity for equipment is achieved.

Description

technical field [0001] The invention relates to the technical field of multimedia navigation, in particular to a video recording method, device and equipment. Background technique [0002] Along with the development of multimedia technology, the driving recorder that is used to record the image and sound on the way of recording the vehicle to obtain the driving record video is more and more widely used. [0003] At present, there are mainly two kinds of driving recorders: intelligent driving recorder and special driving recorder. The main difference between professional driving recorder and intelligent driving recorder is: professional driving recorder only has one function of driving record, while intelligent driving recorder also has some other functions. Functions, such as: online music, weather, navigation and other functions. [0004] Professional driving recorders are generally solutions customized by driving recorder chip manufacturers using the Linux system. The har...
