AIO-3399J开发HDMI-IN功能无法使能
本帖最后由 yong.qian 于 2022-9-15 15:01 编辑系统启动时HDMI-IN芯片驱动相关的信息firefly@firefly:~$ dmesg | grep 35874

系统启动后，系统中video类的设备文件firefly@firefly:~$ v4l2-ctl --list-devices
rkisp1-statistics (platform: rkisp1):
/dev/video3
/dev/video4
/dev/video8

下面是系统启动的hdmi采集脚本，目前无法正确获取到device_id：
firefly@firefly:~$ cat /usr/local/bin/test_hdmirx.sh
#!/bin/bash
device_id=$(v4l2-ctl --list-devices | grep -A1 hdmirx | grep -v hdmirx | awk -F ' ' '{print $NF}')
v4l2-ctl -d $device_id --set-dv-bt-timings query
width=$(v4l2-ctl -d $device_id --get-dv-timings | grep "Active width" |awk -F ' ' '{print $NF}')
heigh=$(v4l2-ctl -d $device_id --get-dv-timings | grep "Active heigh" |awk -F ' ' '{print $NF}')
trap 'onCtrlC' INT
function onCtrlC () {
echo 'Ctrl+C is captured'
killall gst-launch-1.0
exit 0
}
export XDG_RUNTIME_DIR=/run/user/1000

echo " exit"
while true

sleep 10
