How to use VEYE MIPI 327 as "gst appsink"

Question

官方的gst演示是基于gst-launch的，下面的命令运行没问题，可以显示327的画面。

• 视频预览1080p HD(硬件加速)

gst-launch-1.0 v4l2src ! "video/x-raw,format=(string)UYVY, width=(int)1920, height=(int)1080" ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)I420" ! nvoverlaysink sync=false

我结合默认MIPI摄像头的gst appsink代码，尝试327+gst appsink+opencv，一直创建gst pipeline失败。

不知道有没有jetson nano上的imx327+opencv+gst appsink的示例？

多谢！

I think maybe Opencv do not support I420 data format input. Please try this:
v4l2src ! video/x-raw, format=(string)UYVY, width=(int)1920, height=(int)1080 ! nvvidconv ! video/x-raw(memory:NVMM), format=(string)I420 ！ nvvidconv ! video/x-raw, format=(string)BGRx ! videoconvert ! video/x-raw, format=(string)BGR ! appsink
