SOLVED RAW-MIPI-SC535M格式取流设置问题

 您好, 
 我使用了RAW-MIPI-SC535M这款相机执行preview_3588.sh脚本时遇到了问题。脚本的gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=GRAY8,width=$WIDTH,height=$HEIGHT ! autovideosink这一行在报错,完整的报错信息如下:
 Just use 2432*2048@30fps, I2C bus is 7 as a sample. Please modify these values if needed.
 Start MV Camera Preview!

 我希望知道报错的原因以及修改方式,感谢!

 @毛宪历 请问你使用的主板型号是什么?

 @veye_xumm RK3588S-PC,firefly5.10,基于Ubuntu20.04。同时还有一个附带的情况,就是我在C++中使用系统调用(v4l2框架)连接/dev/video0时可以连接,但使用ioctl查询设备支持的模式时发现获取的v4l2_capability.capabilities = 0x84201000,并没有明确的指向某个功能。我想这应该是一个共同的原因引起的,您有什么建议吗?

 @毛宪历 
 这个板子上,请使用如下命令进行测试先:python3 ./v4l2dev_2_opencv_show_grey.py --width 2432 --height 2048 --fps 50 --i2c 7
