大家好，我目前用的平台是DM8168 开发包DVRRDK_02.00.00.23 仿照multich_vcap_vdis.c修改的link参数，想要做到不用编解码，在osd添加图像算法，直接通过HDMI显示出来。链路如下：
/*
Capture (YUV422I) 16CH D1 60fps
|
|
|
IpcFramesOutvpss Link ---------IpcFramesIndsp Link----------algosd link
|
|
|
SW Mosaic
(SC5 YUV422I)
|
|
|
|
display link
Off-Chip HDMI
1080p60
*/
出现的问题：屏幕一片黑，没有视频，只是一闪一闪
修改的各个link参数如下：
