Analysis of source code hotspots of Shandong Bugu Technology live broadcast system: different chips realize high-quality encoding and rendering video GPU acceleration function

  With the rapid development of modern technology, the source code platform of the live broadcast system has been developed and built, which has brought great changes to people's lifestyles. The functions of the source code platform of the live broadcast system, such as friends, short videos, live broadcasts, and communities, have attracted many people more and more. The more enthusiastic you are to watch videos, watch live broadcasts, and share your life on the platform. The user's love also urges the source code platform of the live broadcast system to develop to higher quality. As the core of the source code platform of the live broadcast system, the image quality and system performance need to be maintained and improved. However, different chips may cause the image quality and system performance to decrease. This has also become a hot issue in the development of the source code platform of the live broadcast system. Through the unremitting efforts of the developers, the GPU acceleration function has been developed and released. Image quality and system performance. Now let's analyze the GPU acceleration function in detail.

 

• Benefits of GPU Acceleration

1. The GPU function has the ability to process video data in parallel. The source code platform of the live broadcast system has a huge user base, so it needs to process a large amount of image and video data. image and video processing tasks, thereby improving the performance of the platform, reducing stuttering, and achieving high-quality image and video effects.
2. The GPU acceleration function can accelerate the processing of images and videos. Relying on this capability, the source code platform of the live broadcast system can process and render high-resolution images and videos in real time, which can provide users with higher quality image quality requirements and high-resolution images. The image quality can be output to multiple screens to meet the needs of users with multiple screens.
3. The source code platform of the live broadcast system has many image functions, such as beautification, special effects, etc. These functions often require real-time performance, and the GPU acceleration function has the ability to process image data in real time, which can assist the platform to better access these image functions.
4. The GPU acceleration function can hand over part of the graphics computing tasks to the GPU, reduce the burden on the CPU, and release more CPU resources to handle other tasks. This can improve the performance and response speed of the entire system, and ensure the stability and fluency of the live broadcast platform.

• GPU acceleration function deployment reference code

import cv2
video = cv2.VideoCapture('input.mp4')
fourcc = cv2.VideoWriter_fourcc(*'XVID')
output = cv2.VideoWriter('output.mp4', fourcc, 30.0, (640, 480))
while True:
    ret, frame = video.read()
    if not ret:
        break   
    output.write(frame)  
    cv2.imshow('Processed Frame', frame)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break
video.release()
output.release()
cv2.destroyAllWindows()

• in conclusion

  All in all, for the source code of the live broadcast system, the GPU acceleration function is an important means to improve the real-time image quality and viewing experience, and it is one of the indispensable and important functional technologies.
