* Description:
* Decompress one frame, and output I420 or RGB24(in the future) decoded stream and its length.

* Parameter TYPE Description
* pSrc unsigned char* the h264 stream to decode
* srcLength int the length of h264 steam
* pDst unsigned char* buffer pointer of decoded data
* pDstInfo SBufferInfo& information provided to API including width, height, SW/HW option, etc
*
* return: if decode frame success return 0, otherwise corresponding error returned.
