Design and Implementation of Embedded Media Player Based on Qt
WangJianMin, ZhangHongZhuang （Computer and Information Engineering Department, Shijiazhuang Railway Institute, Shijiazhuang，Hebei ,050043） Abstract: In this thesis, based on the requirement of wireless multimedia terminal system, through comparison of structure features of several popular media players, the author proposes a framework for embedded media player. Also with emphasis on analysis of the existing audio and video synchronization algorithms in MPEG-2, this method can enhance the performance of audio and video synchronization of embedded media player. On this basis, the author designs and makes media player based on Qt and embedded system.
