M210 RTK V2-OSDK 3.8 / 3.8.1和视频流不起作用（样本不起作用）

Question

我已经使用M210 RTK V2（Frimware 1.0.0450）和Zenmuse X4S成功执行了有关遥测，FPV摄像机等的所有OSDK 3.8 / 3.8.1示例。但是，我已经在Ubuntu 16.04中测试了OSDK 3.8和3.8.1，但无法成功使用预制的主摄像机样本（在这种情况下，是用于检索主摄像机图像的camera-stream-callback-sample）。

问题是（OSDK 3.8.1）camera-stream-callback-sample无法正常工作（RC已打开）。它给出了以下错误：

对于OSDK 3.8，结果如下

我不知道该怎么办，因为它是带有受支持的M210RTK V2和Zenmuse X4S的官方OSDK。我已经测试了FPV，并且可以成功运行。

有人可以提供帮助吗？先感谢您。

解决方案：在具有M210 RTK V2的Ubuntu 16.04和OSDK 3.8.1中（所有清单均已满足且RC已打开），必须按以下方式调用示例：

./camera-stream-callback-sample UserConfig.txt /dev/ttyACM0

希望有帮助。
