[DM642]SEED的DDK，如何配置才能同时采集2路以上视频呢？

如何

本帖最后由古董于 2013-9-16 11:59 编辑

第一路是能正常采集的，第二路是参考DDK说明及仿第一路配置的--不正常.
1.BIOS配置
第一路是能正常采集的,第二路有问题.

2.第一路的配置参数：
VPORTCAP_Params SEEDVPM642_vCapParamsChan = {
&nbsp; &nbsp; VPORT_MODE_BT656_8BIT, /* cmode:3 工作模式BT656_8bit */
&nbsp; &nbsp; VPORT_FLDOP_FRAME,&nbsp; &nbsp;&nbsp;&nbsp;/* fldOp:3 帧或场的操作模式，这里选择帧模式 */&nbsp; &nbsp;
&nbsp; &nbsp; VPORT_SCALING_ENABLE, /* scale:1&nbsp;&nbsp;水平方向上缩小1/2使用*/&nbsp; &nbsp;
&nbsp; &nbsp; VPORT_RESMPL_DISABLE,&nbsp;&nbsp;/* resmpl:1 */
