Last week, Xiao Bai for everyone to share a short video app source development function mechanism of the article, the article for you to build a short video platform needs to use some of the basic functions of the implementation mechanism. Let's start with a brief review of the important functional mechanisms mentioned in the previous article. Br/>1. Recommendation mechanism, we can take "recommended value

1, the graphics driver version and the graphics card is not compatible, graphics driver version is very many, not the latest graphics driver is suitable for your graphics card, some old graphics instead of using the older version of the driver more stable, such a situation is recommended to download when the display of the graphics driver, or to the graphics card official website under the appropriate driver. 2, some non-public version of the driver will automatically overclocking the graphics

This paper records a non-reference video quality evaluation algorithm. This is our own laboratory in the first two years of a sister-in-the-job, the algorithm is still relatively accurate, in this record. Note the premise of this algorithm is high-definition video. And it's a coding method of H. The method mainly uses the parameters of two code stream to evaluate the quality: Quantization factor (QP) and
