Embodiment 1

[0029] Figure 1A It is a flow chart of a video data encoding method provided by Embodiment 1 of the present invention. The embodiment of the present invention is applicable to the case of encoding video data. The method can be executed by a video data encoding device, and the device can use software and / or implemented in the form of hardware, and integrated in the device performing the method, specifically, such as Figure 1A As shown, the method may include the following steps:

[0030] S101. Acquire video data.

[0031] In the embodiment of the present invention, the video data may be the original image sequence collected by the image acquisition device, and the image acquisition device may be a terminal equipped with a camera, such as a mobile phone, a video camera and other mobile electronic devices, of course, it may also be a terminal with a camera. Fixed electronic equipment, such as a fixed surveillance camera, etc.

Embodiment 2

[0044] figure 2 It is a flow chart of a video data encoding method provided by Embodiment 2 of the present invention. The embodiment of the present invention is optimized on the basis of the foregoing Embodiment 1. Specifically, as figure 2 As shown, the method may include the following steps:

[0045] S201. Acquire video data, where the video data includes a time stamp.

[0046] In the embodiment of the present invention, the video data may include multiple video frames and time stamps. For example, during the live broadcast of the user, the camera captures the user's image to obtain multiple video frames and the time point at which each video frame is captured, and the time points of the multiple video frames The time series formed by collecting time points is a time stamp.

[0047] S202. Acquire a target frame rate, a target code rate, a target frame number of a group of pictures, and an encoding period of a group of pictures.

[0048] In practical applications, the us...

Abstract

The embodiment of the present invention discloses a video data encoding method, device, equipment, and storage medium, which are applied to an encoder. The video data encoding method includes: acquiring video data; configuring encoding parameters of the encoder; determining a group of pictures according to the encoding parameters A first time interval between two adjacent video frames; encoding the video data according to the encoding parameters, so as to adjust the number of video frames in the group of pictures according to the first time interval. In the embodiment of the present invention, when the smallest unit of the encoding period is fixed, the time interval between two adjacent video frames in the group of pictures is adjusted by configuring the encoding parameters, so as to adjust the video in the group of pictures generated by encoding in the encoding period. The number of frames realizes group-of-picture encoding of any frame size, without a soft encoder for encoding, and meets the encoding requirements of a group of pictures containing fewer video frames, so that specific frames can be quickly decoded when decoding video data, reducing decoding time .

Description

technical field [0001] Embodiments of the present invention relate to the technical field of video encoding, and in particular, to a video data encoding method, video data encoding device, device, and storage medium. Background technique [0002] After the video recording device records images, the encoder encodes the recorded images to form video data, and the video data is decoded and played to display video images on the terminal. [0003] In the encoder of some systems, the encoded video frames include I frames, P frames and B frames, and the video frames between two I frames form a GOP (Group Of Pictures), that is, a GOP contains multiple video frames. Under the premise that the code rate remains unchanged, the more video frames contained in the GOP, the better the image quality of the video, but the GOP contains too many video frames. When decoding the P frame or B frame in the GOP, it needs to be decoded first. To obtain the I frame in the GOP and the previous N pre...
