        @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!
