Problems solved by technology

Interfaces 3 and 4 will occupy DDR for a long time, because video data will continue to be generated, which will cause DDR interface access competition. General system software (accessing DDR through interface 5) may not occupy the DDR interface, resulting in Software runs stuck

Abstract

The invention discloses a video compression method. The method comprises the following steps: receiving frame data; adding a frame header and a frame tail to the frame data; obtaining the number of actual pixel points of the frame data according to the frame header and the frame tail, and removing the frame header and the frame tail; comparing the actual pixel point number with the standard pixelpoint number to judge whether data loss exists in the frame data or not; in response to data loss in the frame data, determining the number of pixel points to be supplemented according to the difference between the actual number of pixel points and the standard number of pixel points; and supplementing the pixel points to the frame data according to the number of the pixel points to be supplemented so as to compress the frame data, and returning to the step of receiving the frame data. The invention further discloses computer equipment and a readable storage medium. According to the scheme provided by the invention, whether the frame data is lost or not is judged by detecting the frame header and the frame tail mark, and the frame with the lost data is complemented, so that the phenomenonof abnormal video display caused by pixel point loss of one or more frames is avoided.

Description

technical field [0001] The present invention relates to the field of video processing, in particular to a video compression method, device and storage medium. Background technique [0002] In a traditional SoC system with video compression function, such as figure 1 As shown, the graphics card (VGA IP) outputs RGB raw data, which does not include frame header and frame tail flag information, and the post-stage module can only rely on resolution information to obtain fixed data (for example, the resolution is 1024x768, it is considered that the first group of 1024x768 pixels obtained is the first frame data, and the second group of 1024x768 pixels is the second frame data...), but due to the huge amount of video data, at 1024x768, 60fps (frame per second ), RGB888 calculation, the amount of data in one second will reach 1024x768x60x3=135MB, and the amount of data in one minute will reach 8GB. Such a huge amount of data will be processed asynchronously through ASYNC before b...
