TI中文支持网大家好，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

请教各位前辈哪里有问题？谢谢
Chris Meng：
你好，
你使用的软件版本过旧，建议升级到最新4.01。
你如果就采集加显示能正常么？下面的分辨率设置不对啊。
pCaptureInstPrm->standard = SYSTEM_STD_1080P_60;
weiliang huang：
回复 Chris Meng:
Chris Meng，你好
首先，感谢你的回答，如果只做cap+dis link分辨率是1080p60fps时确实会报运行错误，日志：
[m3vpss ] 15763: DISPLAY: 39: Field Separate Mode ENABLED for Que 0 !!!
[m3vpss ] 15764: Assertion @ Line: 771 in links_m3vpss/display/displayLink_drv.c: pObj->displayHndl != NULL : failed !!!
加了swms后，运行通过，日志如上。
你所说的分辨率是像usecase里的那样吗？pCaptureInstPrm->standard= SYSTEM_STD_MUX_4CH_D1;
另外官方例程里的VCAP+VENC+VDEC+VDIS – Progressive SD Encode + Decode的usecase是DVRRDK_02.00.00.23\dvr_rdk\mcfw\src_linux\mcfw_api\usecases\ti816x下的multich_progressive_vcap_venc_vdec_vdis.c吗？
我目前是想仿照usecase写个不带编解码的chain，在osd端加算法。
最后感谢你在百忙之中解答我的问题，感谢！
