为什么无法在Imx8mp evk设备上捕获USB视频？

我想再次讨论一下我现在正在努力解决的问题。
我有一个连接了 imx8mp evk 的 usb 捕获设备，我无法使用 GStreamer 和 Qv4l2 捕获视频，bsp 版本是 5.15，下面是崩溃日志

oot@imx8mpevk:~# gst-launch-1.0 -v v4l2src device=/dev/video0 ! waylandsink
将管道设置为暂停...
错误：来自元素 /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: 设备 '/dev/video0' 不是捕获设备。
附加调试信息：
../git/sys/v4l2/v4l2_calls.c(638): gst_v4l2_open (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src0:
