尝试编译了SDK中的sample_vnc想测试一下开发板的编码能力，不过遇到如下错误：
[root@milkv]~# ./sample_venc -c 265 -w 1920 -h 1080 -i /media/user/test.yuv -o enc

我看了一下内核模块的情况：

好像主要模块都加载了。
有朋友能帮忙看看到底问题在哪里，谢谢。

你可以尝试注释venc相关编译，比如说venc下有makefile，你可以注释一下

不太理解，创建通道失败应该注释掉谁？注释掉这句后面怎么工作？

这个明显是驱动有问题 这个ioctl估计都没实现，我这边也是同样的错误，其他的sample没一个能用的
