系统启动后，系统中video类的设备文件

1. firefly@firefly:~$ v4l2-ctl --list-devices
   
2. rkisp1-statistics (platform: rkisp1):
   
3.         /dev/video3

下面是系统启动的hdmi采集脚本，目前无法正确获取到device_id：

1. firefly@firefly:~$ cat /usr/local/bin/test_hdmirx.sh
   
2. #!/bin/bash
   
3. 
   
4. device_id=$(v4l2-ctl --list-devices | grep -A1 hdmirx | grep -v hdmirx | awk -F ' ' '{print $NF}')
   
5. 
   
6. v4l2-ctl -d $device_id --set-dv-bt-timings query
   
7. 
   
8. width=$(v4l2-ctl -d $device_id --get-dv-timings | grep "Active width" |awk -F ' ' '{print $NF}')
   
9. heigh=$(v4l2-ctl -d $device_id --get-dv-timings | grep "Active heigh" |awk -F ' ' '{print $NF}')
   
10. 
    
11. trap 'onCtrlC' INT
    
12. function onCtrlC () {
    
13.         echo 'Ctrl+C is captured'
    
14.         killall gst-launch-1.0
    
15.         exit 0
    
16. }
    
17. 
    
18. export XDG_RUNTIME_DIR=/run/user/1000
    
19. gst-launch-1.0 alsasrc device=hw:2,0 ! audioconvert ! audioresample ! queue !  alsasink device="hw:1,0" &
    
20. gst-launch-1.0 v4l2src device=$device_id ! queue ! video/x-raw,format=RGB ! capssetter replace = true caps="video/x-raw,format=BGR,width=$width,height=$heigh" ! glimagesink &
    
21. 
    
22. echo "[Ctrl + C] exit"
    
23. while true
    
24. do
    
25.         sleep 10
    
26. done
