Embodiment 1

[0037] figure 1 A schematic diagram of a video file generation process provided by an embodiment of the present invention, the process includes the following steps:

[0038] S101: Acquire and save each collected first video frame data according to the received recording instruction.

[0039] The video file generation method provided by the embodiment of the present invention is applied to an electronic device, and the electronic device may be an image acquisition device and a terminal including a mobile phone and other intelligent devices.

[0040] In this embodiment of the present invention, in order to generate a corresponding video file, a recording instruction may be sent to the electronic device, and after the electronic device receives the recording instruction, the electronic device acquires each first video frame data collected, and analyzes the acquired data for the first video frame. The data of each first video frame is saved.

[0041] The sending of the recording...

Embodiment 2

[0050] In order to accurately control the frame rate of the generated video file, on the basis of the above-mentioned embodiment, in the embodiment of the present invention, after acquiring and saving the collected data of each first video frame, the corresponding video file is generated. Before, the method further includes:

[0051] Determine the target time interval between two adjacent frames according to the preset frame rate;

[0052] Regarding the sequence in which the stored first video frame data is stored, if the video frame data is the first video frame data, the video frame data is stored unchanged; if the video frame data is not the first video frame data, then determine whether the time interval between the video frame data and the time stamp of the last saved video frame data is greater than the target time interval, if so, save the video frame data unchanged, otherwise, delete the video frame data.

[0053] In the embodiment of the present invention, in order ...

Embodiment 3

[0057] In order to generate a video file that meets user requirements, on the basis of the above embodiments, in this embodiment of the present invention, before acquiring and saving each first video frame data collected according to the received recording instruction, the The method also includes:

[0058] If the preview instruction is received, the collected second video frame data is displayed according to the screen refresh rate of the display device.

[0059] In the embodiment of the present invention, when there is a need to generate a video file, if you want to view the collected video frame data, you can send a preview instruction to the electronic device. After receiving the preview instruction, the electronic device displays the currently collected video frame data through the display device. The user observes the currently collected second video frame data through the display device, and when the video frame data meets the user's needs, can send a recording instruct...

Abstract

The embodiment of the invention provides a video file generation method and device, equipment and a medium, which are used for solving the problem that a generated video file cannot be played smoothly due to the influence of the screen refresh rate of display equipment for displaying in the prior art. In the embodiment of the invention, the electronic equipment obtains and stores each piece of collected first video frame data according to a received recording instruction, and if the electronic equipment receives a recording ending instruction, a corresponding video file is generated according to each piece of stored first video frame data and a timestamp corresponding to collection of each piece of first video frame data. In the embodiment of the invention, the video file is generated according to each piece of collected first video frame data, so that the generated video file is not influenced by the screen refresh rate of the display equipment for displaying, and the video file can be smoothly played on display equipment with other screen refresh rates.

Description

technical field [0001] The present invention relates to the technical field of data processing, and in particular, to a method, apparatus, device and medium for generating a video file. Background technique [0002] With the development of society, people usually record their lives by recording videos. In the prior art, in order to check the effect of video recording, the user usually previews the video through a display device when recording the video. [0003] Therefore, in the prior art, when a video file is generated, the video file is generated according to the video frame data correspondingly displayed when the display device performs a preview. However, due to the limitation of the screen refresh rate of the display device, when the video file is generated based on the video frame data previewed by the display device, it is generated according to the screen refresh rate of the display device. If other display devices with a screen refresh rate display the video file,...
