@hujun 驱动的这个warning不用管它，不影响使用。
建议参考这个链接的6.7.1，6.7.2部分，完整执行一下。

@veye_xumm 已经反复执行过几遍，显示器上已经没有图片显示，并且也使用过保存图片的命令，生成了图片，却在yuv player中无法播放。

操作系统吧hdmi输出休眠了吧？加上个鼠标动一下就可以了。

看一下part8.

严格按照步骤走，肯定没问题。你可以把你的执行步骤先后顺序描述一下，我看一下。

看你截图的这个小于号，应该是已经接收到一张了。
只是你的命令要接收5张，所以还在等待继续触发。

你理解错了，这个命令是抓取图片保存到文件中，不是显示到屏幕上的。

@veye_xumm 好的，非常感谢您的帮助。
另外我想询问，mv系列的相机，可否使用GitHub中上面这个v4l2文件夹中Python的demo，我在其它贴子上说，不支持。如果可以，有相关手册吗？

@hujun MV系列的不行。因为MV系列输出的是raw数据，不能直接显示到屏幕上去。
不过MV系列支持一种纯粹为了调试用的格式，就是UYVY数据格式。
你可以参考一下我们在jetson平台写的gstreamer命令行试试：

但是话还得说回来，mv系列的东西做实时预览，并没有实际用途吧？

@veye_xumm 是的，我们并不是想实现实时预览。我们想通过qt控制MV相机，实现采集图片。最后由qt实现一系列的图像处理，点云生成的操作。目前问题是，无法在qt中调用，因为所用的都是命令行。

@hujun qt直接参考我们c语言的demo，打开/dev/video0获取数据即可。

@veye_xumm 这篇文档我看了很久，您指的c语音demo是yavta文件夹中的c程序吗？
