OMX_U32 nPortIndex
 
OMX_U32 nQFactor
 

Detailed Description

Q Factor for JPEG compression, which controls the tradeoff between image quality and size. Q Factor provides a more simple means of controlling JPEG compression quality, without directly programming Quantization tables for chroma and luma

STRUCT MEMBERS: nSize : Size of the structure in bytes nVersion : OMX specification version information nPortIndex : Port that this structure applies to nQFactor : JPEG Q factor value in the range of 1-100. A factor of 1 produces the smallest, worst quality images, and a factor of 100 produces the largest, best quality images. A typical default is 75 for small good quality images
