Dear TI 专家,
这是原本的chain (我有两颗镜头以及一个Panel):
Iss Capture -> Select_1 (后镜头) -> Framecopy(镜像) -> Merge_1 -> Select_2 ->VPE ->Display
-> Select_1 (前镜头) -> (Nothing) -> Merge_1
透过此chain可以看到前后镜头切换的效果且没有问题 (切到后镜头显示镜像，切到前镜头正常显示)
但是在将usecase : vip_single_cam_lane_detection 移植在前镜头的link上时却无法正常显示
==============================
如图，以下是修改移植后的chain =>红色框起部分 (备注: 我们板子上没有EVE Core , 所以拿掉了Alg_ImagePreProcess)
情况是 我目前只有一个Panel所以靠Select_2来切换前后镜头
前镜头想要达到可以做车道偏移警示的演算法
后镜头只想做到Framecopy(镜像)
目前可以透过某些方式达到前后镜头的切换
在切换时后镜头显示没有问题
但切到前镜头画面却出不来
===============================
所以我印出link的状态

发现前镜头那路的Vpe的link 在一开始的时候 就有 Out Drop FPS 的现象
不太明白VPE Link受到什么影响
想请问这如何改善这个问题呢?
请问我的link这样做有任何错误吗?或影响延迟的地方吗?
是否有哪个link会影响造成这个结果呢? 可能可以做哪些修改呢?
再麻烦各位专家了 谢谢!

Dear TI 专家,
(更新)
原本怀疑是演算法造成的延迟等状况
所以我做了一个测试
我将Alg_ImgPyramid,Alg_LaneDetect以及Alg_ObjectDraw link移除
前镜头的chain留下Vpe_1,Dup,Merge,Sync结果状况与现在相同
chains : Iss_capture -> select_1(前镜头) -> Vpe_1 -> dup ->Merge_1 -> Sync -> Merge_2 -> select_2 ->Vpe_2 -> display
-> select_1(后镜头) -> framecopy -> Merge_2 ->

Dear TI 专家,

接下来我又拿掉了Vpe_1链接结果还是一样，看起来链接塞住了
chains : Iss_capture -> select_1(前镜头) -> dup ->Merge_1 -> Sync -> Merge_2 -> select_2 ->Vpe_2 -> display
-> select_1(后镜头) -> framecopy -> Merge_2 ->

您好，
您的问题我们这边也是需要求助英文论坛的工程师，晚一点我们升级到英文论坛看下哈。

Dear Cherry,
(更新)
目前link无法正常执行的原因找到了，是初始化值错误的关系
看起来整个chain已经打通了
但是另一个问题产生
如下图目前是我完整的chain
后镜头(framecopy 那边的Link)呈现出来的画面是正常的
但是前镜头(lanedetect 那边的Link)画面很奇怪如下图
我在猜测是否更VPE link设定有相关呢?
原因如下先前我有一个案例
我将VPE放在framecopy前面结果导致画面呈现奇怪的状态
但放在framecopy后又变正常
然后此次在lanedetect前镜头的chain共会经历两个VPE
第一个VPE是用来转格式SYSTEM_DF_YUV420SP_UV 用于 pyramid后的演算法
第二个VPE是用来做两颗镜头的裁切功能
这有关连吗?或是可能什么样的问题造成的呢?
Best Regards,
David
