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, comprising the following steps: receiving frame data; adding a frame header and a frame tail to the frame data; obtaining actual pixel points of the frame data according to the frame header and frame tail, and removing the frame header and frame tail; Compare the actual number of pixels with the standard number of pixels to determine whether there is data loss in the frame data; in response to data loss in the frame data, determine the number of pixels to be supplemented according to the difference between the actual number of pixels and the standard number of pixels; The number of pixels of the frame data is complemented by pixels for compression, and returns to the step of receiving the frame data. The invention also discloses a computer device and a readable storage medium. The scheme proposed by the present invention judges whether the frame data is missing data by detecting the frame head and frame tail marks, and complements the frames with missing data, so as to avoid the loss of pixels in one frame or several frames, resulting in abnormal video display Phenomenon.

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 traditional SoC systems with video compression functions, such as figure 1 As shown, the graphics card (VGA IP) outputs RGB raw data. The raw data does not have frame header and frame end flag information. The latter module can only rely on the resolution information to obtain fixed data (for example, the resolution is 1024x768, then it is considered that the first group of 1024x768 pixels obtained is the first frame of data, and the second group of 1024x768 pixels is the second frame of data...), but due to the huge amount of video data, at 1024x768, 60fps (frame per second ), RGB888 calculation, the data volume in one second will reach 1024x768x60x3=135MB, and the data volume in one minute will reach 8GB. Such a huge amount of data will be processed asynchronously through ASYNC befo...
