[0075] refer to image 3 , which is a schematic diagram of the functional modules of the video recording device provided by the first embodiment of the present invention. As mentioned above, the video recording device can be installed in various mobile terminals with video recording function, and can also be installed in fixed terminals with video recording function. The video recording device comprises a queue generation module 31, a recording module 32, a storage control module 33 and a file generation module 34, wherein:

[0076] The queue generating module 31 is used to generate a data cache queue, and the generated data cache queue is used to store video recording data obtained during video recording.

[0077] When the queue generation module 31 generates the data cache queue, it can be generated according to a user-defined queue generation instruction; it can also be generated according to a queue generation rule preset in the device, for example, the generation rule ca...

[0084] In the video recording device provided by the second embodiment of the present invention, the storage control module 33 is specifically configured to compress the video recording data acquired by the recording module 32 into data frames and store them in the data buffer queue. Therefore, the length of the data buffer queue in this embodiment may be in units of data frames. For example, based on the frame rate of 30FPS, when the data cache queue length is 1200 frames, the queue can memorize (cache) the images within the previous 40s at the longest.

[0085] see Figure 4 As shown, in the present embodiment, the queue generation module 31 includes a video data cache queue generation submodule 311 and an audio data cache queue generation submodule 312; wherein the video data cache queue generation submodule 311 is used to generate the video data cache subqueue; Buffer queue generation sub-module 312 is used to generate audio data cache sub-queue; video data cache sub-queu...

[0097] refer to Figure 5 , which is a basic flowchart of the video recording method provided by the third embodiment of the present invention. It includes:

[0098] S501: Generate a data cache queue.

[0099] The data cache queue generated in this step is used to store video recording data obtained during video recording. The data cache queue can be generated according to a user-definable queue generation instruction, or can be generated according to a queue generation rule preset in the device. For example, the generation rule is to automatically generate a data buffer queue with a preset length after the video recording function is detected and before the video recording is performed. It should be understood that, in this embodiment, the length of the data cache queue can be preset before the device leaves the factory, or can be flexibly set by the user according to his own needs. For example, after the user estimates the duration of the content segment he is currently ...

Abstract

This invention discloses a video recording method, device, and a terminal. The method comprises the following steps: before recording the video, generating a data cache queue; and, after recording the video to acquire video recording data, storing the acquired data into the data cache queue. The following storing principle is adopted during the storing process: when the data cache queue is full, deleting the video recording data firstly stored in the current data cache queue, and storing the newly acquired video recording data in sequence; and after receiving a recording stop instruction of a user to stop recording, extracting the video recording data from the data cache queue to generate a video file. The method provided by this invention has the following beneficial effects: the acquired video file only contains the video data during the recent user interesting period before recording is finished; the storage space is greatly reduced; the resource utilization rate is improved; the intelligence of the video recording function is improved; and, the satisfaction degree of the user experience is further improved.

Description

technical field [0001] The present invention relates to the field of intelligent terminals, and more specifically, to a video recording method, device and terminal. Background technique [0002] With the advancement of technology, mobile terminals have entered every aspect of people's lives. Mobile terminals are widely used in people's daily work, entertainment, leisure and so on. [0003] Because of the portability of the mobile terminal, more and more users like to use the mobile terminal to watch some live videos or record interesting video content through the video recording function at any time. Watching live video with a mobile terminal is not limited by time and place, as long as there is a mobile terminal that can connect to the network, as long as the live video time is up, the user can watch the live video. When many users watch live video, they prefer to record the live video so that they can share the live video with relatives and friends again, instead of re-d...
