编解码器的xvid静态库的c++封装 编码： m_vdo_enc->Encode(pBuffer) // 这里pBuffer是BGR24的320x240的数据 编码如果成功，就会自动调用PostEncHandler函数，就可以得到编码后的结果 解码： m_vdo_dec->Decode(xvid, xvid_len) // 传入的存有xvid数据的buffer和长度 解码成功后，会自动调用PostDecHandler，注意对于流媒体数据而言，在这个函数中还有

The receiver’s roles are to receive a single frame and store in the BRAM. After that, a flag is initialised to run the customised frame buffer that reads the pixels BRAM and writes them at the VGA port. Once a pixel is written to the VGA port
