H.264 encoding algorithm, because of its high compression ratio and excellent image quality, has become one of the most widely used video coding standards. In the H.264 encoding algorithm, intra-frame and inter-frame mode selection is an important step. This paper aims to study the H.264 intra-frame mode selection algorithm, explore the schemes to optimize its performance, and implement it on the DSP platform.Firstly, we study the H.264 standard, understand the principles and implementation process of intra-frame and inter-frame mode selection. Secondly, we investigate the current mainstream intra-frame mode selection algorithms and analyze their advantages and disadvantages. Then, we propose a machine learning-based intra-frame mode selection algorithm, which is trained on a large data set to improve the model's identification accuracy of image features. Finally, we implement the optimized intra-frame mode selection algorithm on the DSP platform, test its running speed and image quality, and evaluate the practical application value and practicality of the algorithm.Keywords: H.264 encoding; intra-frame and inter-frame mode selection; machine learning; DSP platform.
