固件类型：官方提供的固件
固件文件名称：ROC-RK3588S-PC_Buildroot_v1.0.2a_221103
固件下载地址：rk3588_repo_sdk_v1.0.2a.7z

通过v4l2-ctl对摄像头进行取流测试，但输出文件大小为0，没有保存任何数据。
使用SDK版本为：rk3588_repo_sdk_v1.0.2a.7z， Bundle：rk3588-v1.0.2a-to-v1.0.2b.7z； rk3588-v1.0.2b-to-v1.0.2c.7z
编译为BuildRoot系统和Debian系统测试结果相同。

测试命令如下：
v4l2-ctl -d /dev/video0 --set-fmt-video=width=640,height=480,pixelformat=NV12 --stream-mmap=3 --stream-to=/tmp/out2.yuv --stream-count=20 --stream-poll --verbose

v4l2-utils 好像需要 1.16.5 之前的版本才能取得到流，你可以用 gstreamer 取一下流看看可不可以

我试了gstreamer，命令如下：
firefly@firefly:~$ gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=NV12,width=800,height=600,framerate=30/1 ! kmssink

输出结果如下：
Setting pipeline to PAUSED …
Using mplane plugin for capture
Pipeline is live and does not need PREROLL …
Pipeline is PREROLLED …
Setting pipeline to PLAYING …
New clock: GstSystemClock
ERROR: from element /GstPipeline:pipeline0/GstKMSSink:kmssink0: GStreamer encountered a general resource error.

好像还是不行。
另外，我在Debian的固件中使用V4L2 TestBench工具，能够看到摄像头图像，也能够把图像保存到文件中。
那很奇怪，使用v4l2-ctl为什么不行？而且我自己写了一个通过v4l2的取流的程序，读取的buffer为空。

kmssink 指定plane-id 或者用 waylandsink

请问楼主问题解决了吗
