Abstract

The invention discloses a video image display method, which comprises the following steps of: applying for a frame memory, and converting a frame memory address into a frame memory identifier; analyzing the video frame data, and placing the video frame data into a frame memory; transmitting the frame storage identifier to an application program for playing the video, calling a hardware rendering language through the application program, and transmitting the frame storage identifier to the hardware rendering language by the application program; data rendering is performed by the hardware rendering language using the frame data. According to the embodiment of the invention, smooth film watching can be realized without occupying too much memory, and the problem of poor film watching experience feeling under the condition of poor CPU computing power is also solved.

Description

technical field [0001] The invention relates to the technical field of video playing, in particular to a video image display method and device, computing equipment and a readable storage medium. Background technique [0002] Currently, there are two copies of video content when playing a video. One time is in the process of transferring to the player after FFmpeg applies for memory. Among them, when FFmpeg plays video, it initializes video memory in the data driver module (DRM), then applies for memory, and fills it with frame data. In the process of filling the frame data, there will be a large data copy operation of the CPU. After copying, the frame data will be transmitted to the player, and finally the player will send the frame data to the DRM through the rendering language OPenGL EGL to execute the underlying driver of the display. The working and final composite images are sent to the monitor to display the video, and there will also be data copies in the process of...
