The design and implementation of an embedded high definition player

For the problems that MPlayer encountered when decoding high definition video on the embedded platform of Intel´s CE3100, a novel dual-core player is designed according to the features of CE3100. The dual-core player includes one soft core player based on software decoder and one hard core player based on hardware decoder. Then, a main control center is introduced in the front of the player. The control center is responsible for analyzing and getting attributes of various types of media files, and determining to start soft core player or hard core player according to these attributes, which includes codec, bit rate, resolution and so on. At the same time, the implementation of the player is introduced in details. Eventually, it shows the performance and advantage of the player through comparative experiment.
