我想要回灌拿图片回灌rdk x5的vse，但是我扫了下 VSE/GDC 实体块里是否标注了 m2m / device node，但好像没有
sunrise@ubuntu:/app/cdev_demo/v4l2$ for md in /dev/media*; do
media-ctl -d “$md” -p | awk -v md=“$md” ’
/^- entity [0-9]+: / {show=($0 ~ /vs-vse|vs-arm-gdc/i); if (show) print “====”, md, “====”, $0}
show && /subtype/ {print " " $0}
show && /device node/ {print " " $0}
’
done

你好，V4L2在我们手册有一个拿图片回灌的案例，您看看这个案例对您现在做的事情有没有什么帮助呢？这块在手册的直达链接是：V4L2使用 | RDK DOC
