运行无报错，但lcd没有显示摄像头画面。

文件系统是烧写的是2021-12月发布的出厂文件系统。kernel和设备树是我自己修改编的。请问有谁知道这个报错的原因吗？有的麻烦回复一下，谢谢！！！

摄像头输出配置的分辨率对吗

ov5640需要用出厂内核，你自己的内核 可能没调试好。播放视频 是直接gst-paly-1.0 + 视频文件

1.内核配置已经加过对ov5640的支持了，driver/media下的源码也是替换了最新发布的内核源码，设备也已经识别到了，就是使用命令播放失败，log也暂时看不出问题点。
2.目前播放视频是用的gst-player-1.0+文件名，不过只有声音，lcd没有显示视频，感觉和解码有关

上边那个命令中有设置输出的大小和格式， width=(int)1024, height=(int)768, 这个大小ov5640也支持该分辨率。

是不是你的lcd没起来，没驱动起来？
