TI中文支持网老师您好，我现在在用DM368 EVM的板子做视频编码，板子上有分量输入的接口，并且dvsdk的demo里面有选择分量输入的选项，但是我分量输入的时候demo运行报错：Error: Failed to create capture device. Is video input connected? 请问老师是什么原因，是需要配置什么东西吗？

Zhao Xin，
请问你的输入是720p么？

Starting the Standalone Demo on DM365
With the DM365 EVM boards when you connect the EVM hardware, a pre-loaded example runs automatically on your video display. This example captures 720p component video and displays it as-is (i.e. without processing) to the connected HD display. The example runs automatically with no connection to a workstation in the default boot configuration. The DM365 EVM does not run the DVSDK demo out of flash out of the box.
