      我刷了这系统
      使用这个命令来播放usb摄像头 800w像素
      9027ebb2-4e17-47ad-97ad-582159dd359a-image.png
      和这个
      75f8e032-8217-43ba-b7eb-110c5a8f8133-image.png
      都不能播放
      错误是这个
      036344a3-0ec6-495b-9494-40d097eeb6ce-image.png

      但是第一条命令 在0302的系统中是可以正常播放800w像素的摄像头的

              @jugg 确认摄像头支持的格式,分辨率,帧率?是否OK

                  @jugg 我现在的机器是0303的固件,测试1080p/25fps没有发现问题。等会更新固件测一下。

                      @jugg 我这边测试0306的固件也是正常的。两路1080P/25FPS。

                      gst-launch-1.0 v4l2src device=/dev/video20 ! image/jpeg, width=1920, height=1080, framerate=25/1 ! jpegparse ! mppjpegdec ! videoconvert ! fpsdisplaysink sync=false signal-fps-measurements=true
                      
                      gst-launch-1.0 v4l2src device=/dev/video22 ! image/jpeg, width=1920, height=1080, framerate=25/1 ! jpegparse ! mppjpegdec ! videoconvert ! fpsdisplaysink sync=false signal-fps-measurements=true

                          @jugg 不好意思,手上目前没有4K的设备,要晚一点才能测试。你可以尝试修改如下配置:
                          /etc/profile.d/gst.sh
                          默认的最大分辨率改为你目前sensor的最大分辨率。
                          export GST_V4L2SRC_MAX_RESOLUTION=3840x2160

                            @jugg 实际测试4K 3840*2160 30fps MJPG格式没有问题。
