Abstract

The invention discloses a method for reducing video coding time delay, so as to effectively reduce coding time delay in image video coding. The method comprises steps that: two video frame buffers are placed in handling the video coding, one frame of image data is collected by each video frame buffer in turns, one video frame buffer collects one frame of image data and the other video frame buffer collects the next frame of image data; and when CPU completes the video coding of one frame of image in one video frame buffer, the CPU continues to handle the video coding of the next frame of image in the other video frame buffer and the work is cycled.

Description

technical field

[0001] The present invention relates to a video coding processing method, in particular to a method for reducing video coding time delay,

[0002] It belongs to the technical field of digital video processing. Background technique

[0003] In video communication, video encoding usually consists of several parts: 1) Video acquisition: According to the video acquisition of each frame, the digital signal is stored in the video buffer in the form of data. 2) Video encoding: The original uncompressed video data is compressed by the CPU, and encoding requires reference frames, so the reference frames are cached. 3) Video output. In an embedded system, the processing power of the CPU is limited. For some advanced formats, such as H.264 and AVS video encoding, it is difficult to process in real time and requires a certain amount of processing time. In addition, due to the need for reference frames, the processing time of the CPU is increased, resulting in increase...
