Video recording method and video recording device

Abstract

The present invention relates to a video recording method and device, wherein the video recording method includes: step 11, taking a screenshot of a specific image, and storing the intercepted picture in a specific disk; step 12, according to the available space of the disk size, set the maximum number of screenshots; Step 13, when the number of the pictures in the disk reaches the maximum number of screenshots, generate a temporary video from the picture, and clear the picture from the disk; Step 14 , and synthesize the temporary video obtained by multiple synthesis into the result video. The advantage of the present invention is that, by controlling the quantity, size and quality of the exported pictures, under the condition of limited disk space, the export of pictures and the synthesis of videos can be completed, and the control of the quality, length and other aspects of the final video can be easily realized.

Description

technical field [0001] The invention relates to the field of video processing, in particular to a video recording method and a video recording device. Background technique [0002] In many scenarios, the user often needs to record the image output by the display screen into a video to meet the needs of repeatedly viewing the image. [0003] Most of the current video recording methods are realized by calling the interface provided by the operating system or the display driver. These methods usually need to write complex underlying codes to obtain the image data in the display buffer, and also involve the implementation of the encoding algorithm for video generation. etc. If you want to integrate this method into existing program modules, you often need to carry out a large transformation on it. [0004] In order to avoid the defects of the above-mentioned video recording method, other video recording methods (such as the program FFmpeg) are also proposed in the prior art, wh...

Problems solved by technology

However, this approach also has serious flaws:

[0005] The exported picture will occupy the storage space of the disk. For a disk with limited available space, it is easy to have no space to store the exported picture, or no space to store the video synthesized from the picture.

[0006] It can be seen that the above-mentioned existing video recording scheme obviously still has inconvenience and defects, and needs to be further improved urgently.
