DvppGetOutParameter

Syntax	*int32_t DvppGetOutParameter(void in, void* out, int32_t cmd)**
Function	Obtains the output buffer size of the JPEGD/JPEGE/PNGD module.
Input	in pointer, which varies according to the module. For details, see Table 1. out pointer, which varies according to the module. For details, see Table 1. Command word (CMD)
Output	Output buffer size of each module: For the JPEGE function, the output buffer size is the value of jpgSize in the sJpegeOut struct. For the JPEGD function, the output buffer size is the value of yuvDataSize in the JpegdOut struct. For the PNGD function, the output buffer size is the value of outputSize in the PngOutputInfoAPI struct.
Return Value	0: success –1: failure
Instructions	The caller calls the DvppGetOutParameter function, passes the in and out pointers and the correct CMD command word. The calling example is as follows: For details about the JPEGD module, see Implementing the JPEGD Function. For details about the JPEGE module, see Implementing the JPEGE Function. For details about the PNGD module, see Implementing the PNGD Function.
Restriction	None
