hi 是什么解决办法呢 能发下么 应该是学校的统一要求 还有一个问题就是目录的点太稀疏了 谢谢

Have you install opencv to system library path?

Do you use TinkerOS? You might need update video packages from https://github.com/rockchip-linux/rk-rootfs-build/tree/master/packages/armhf/video, because i have fix some bugs in gstreamer-rockchip/mpp/gstreamer-rockchip-extra when writing this program......

And make sure your kernel have RGA enabled.

There are so problems in dwc2 usb port.. Could you try a lower resultion?

Did you use `output-io-mode=dmabuf-import`?

It's due to`dmabuf-import `.. I'm not sure why it failed. Using `output-io-mode=dmabuf` have a bad impact on performance.

It's fixed now, please update gstreamer-rockchip-extra. https://github.com/rockchip-linux/gstreamer-rockchip-extra/commit/11648d7e2a222c2ece0dd0e79e696606d03989ec

For mipi camera, you don't need to use mppvideodec, replace it with "video/x-raw,format=NV12,width=(int)1920,height=(int)1080"

autovideosink换成具体的sink测试吧
