基于预测的网络视频流平滑回放

Network Video Stream Smooth Playback Based on Prediction

以公开源码为基础,利用Microsoft Visual C++实现了一个基于预测的二级缓冲区结构的视频播放器。通过本地流媒体文件播放实验及实际网络流媒体文件播放实验,表明这种基于预测的视频流回放模型可以平滑回放速率,提高回放质量。

Through Rewriting and optimizing the open codes with Microsoft Visual C＋＋, realizes a video player with double buffer structure prototype. By using the MPEG-4 streaming file as testing data source, experiments under different conditions, include local playback and real network stream playback. The experiment results show that the forecasting model can smooth multimedia streaming playback, and improve the quality of playback.
