在使用微雪的DSI屏显示imx307实时预览的指令时，指令被正常运行，但是屏幕却没有图像显示的问题

@clemente 摄像头图像和DSI屏只有一个能正常运行，屏亮摄像头图像就不显示，或者把屏关了摄像头图像就能实时显示到HDMI了

@veye_xumm 是的，我看过了这篇文章，我换成了V4l2模式来驱动摄像头，但是产生了一个新的疑问，V4l2模式下似乎帧率是非常低的，我甚至认为它只有10帧不到，请问这是正常现象吗
-
@veye_xumm 我尝试修改不同的分辨率和帧率，发现只有480p能勉强达到流畅的效果，1080p和720p帧率都非常的低。在此先谢谢您的解惑。

主要是由于用软件做的图像格式转换导致的。
你可以试一下v4l2convert，这个是用了硬件的转换。gst-launch-1.0 v4l2src io-mode=dmabuf device=/dev/video0 ! "video/x-raw,format=(string)UYVY, width=(int)1920, height=(int)1080,framerate=(fraction)30/1" ! v4l2convert capture-io-mode=dmabuf output-io-mode=dmabuf ! autovideosink sync=false -v -
@veye_xumm 我尝试了这个新的指令，稍微有一点改善，但是不是很明显，延时和帧率还是不理想，这是最好的方案了吗，我想知道有没有更好的解决方案，再次谢谢！
