TI中文支持网现通过FPGA 将相机输出数据转换成bt656格式，分辨率是720*576， 现在通过dm8168来进行采集，8168端的代码如下：
static void mcfw_chain_init(UInt32 scaleWidth, UInt32 scaleHeight)

// Set the scale parameters.

for (i=1; i < DEI_LINK_MAX_CH; i++)
prm_dei.outScaleFactor[DEI_LINK_OUT_QUE_DEI_SC][i] = prm_dei.outScaleFactor[DEI_LINK_OUT_QUE_DEI_SC][0];
prm_dei.enableOut[DEI_LINK_OUT_QUE_DEI_SC] = TRUE; prm_dei.outQueParams[DEI_LINK_OUT_QUE_DEI_SC].nextLink = gVdisModuleContext.displayId[0];

#endif
/* Display link init */

/* create link */
System_linkCreate(gVcapModuleContext.captureId, &prm_capture, sizeof(prm_capture));
System_linkCreate(gVcapModuleContext.deiId[0], &prm_dei, sizeof(prm_dei));
System_linkCreate(gVdisModuleContext.displayId[0], &prm_dis, sizeof(prm_dis));
/* setting frames from which channel should be display */

prm_switch_ch.activeChId = 0;
System_linkControl(gVdisModuleContext.displayId[0], DISPLAY_LINK_CMD_SWITCH_CH, &prm_switch_ch, sizeof(prm_switch_ch), TRUE);
}
请问下以上代码该怎么进行修改？
Chris Meng：
你好，
主要修改包括采集的VIP通道，采集的分辨率，采集的位宽，同步特性等。
