【Parameter Description】

Parameter		Decription
MODULEPARAM	OnePack	Mode in which streams are obtained 0: Streams are obtained in multi-packet mode. 1: Streams are obtained in single-packet mode.
	H264eVBSource	Mode in which the VB is obtained for the reference frame and reconstruction frame 2: The private VBs are used. 3: The VBs are allocated by the user.
	PowerSaveEn	Low-power parameter control switch 0: The low-power parameters are disabled. 1: The low-power parameters are enabled.
	MiniBufMode	Mode of allocating the stream buffers 0: The stream buffers are allocated based on the resolution. 1: The lower limit for the stream buffer size is 32 KB. Users need to ensure that the size of the allocated stream buffer is appropriate.
