px30-android8.1-USB攝像頭錄製視訊異常
kernel中 定義CONFIG_ROCKCHIP_RGA2=y
dts中rk_rga開啟
&rk_rga {
status = "okay";
};
將附件v4l2-ctl推到板子/vendor/bin/目錄，然後輸入如下命令：
v4l2-ctl:
v4l2-ctl --verbose -d /dev/videoX --set-fmt-video=width=640,height=480,pixelformat='MJPG' --stream-mmap=4 --set-selection=target=crop,flags=0,top=0,left=0,width=640,height=480
videoX 可以通過 grep -H ‘’ /sys/class/video4linux/video*/name 檢視。 使用
v4l2-ctl -d /dev/videoX --list-formats-ext 可檢視攝像頭支援的格式及幀率資訊
px30_android-8.1\device\rockchip\rk3326\rk3326_m2g\media_profiles_default.xml
在media_profiles_V1_0.xml中刪掉720x480的制式，以下解析度都支援，可以在media_profiles_V1_0.xml中自己新增上。
(640x480) (160x120) (320x240) (352x288) (800x600) (1280x720)
(1280x1024)
