Hi @pan87232494 I recommend reading the recent updates of the issues, there is some usuful information over there.

Also, can you please try:
ffplay -f video4linux2 -list_formats all /dev/video0

you might need the ffmpeg package.

bingrui pan · Answer 2 · Tue Oct 30 2018 10:41:26 GMT+0800 (China Standard Time)

many thanks for your replay. I did go through issue list, and tried method of changing avconv -f video4linux2 ... to avconv -f v4l2 -standard pal ... , but still not work.

here is output

I tried one more time using your install.sh to setup on clean env, raspbian image and boot/config, keep the same. And the raspbian lite image is not able to boot in my raspberry Pi 3B+, would you please provide a workground will appreciated.
pi 2 --- USB TTL Serial cable----- pi0 ---------micro usb ------ pi0 (as client) or a window 10 PC
|------------------easycap--------------s video convert-----------|

then I see green lines get displayed when I use pi0 as client, but still not working, and I get black image from test output

finally , I get video displayed. but seems keyboard is not pass through from web to pi0, from pi0 to the machine is ok.
debuging now
seems due to key.php from
root@raspberrypi:/var/log/lighttpd# tail -f error.log
2018-10-30 17:21:27: (mod_fastcgi.c.2543) FastCGI-stderr: PHP Parse error: syntax error, unexpected 'system' (T_STRING) in /opt/diy-ipmi/Pi3/html/key.php on line 6

----below is command to make video work
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install dkms
reboot
and mplayer tv:// -tv device=/dev/video0 -hardframedrop will see video come out.

It is strange, at begining web monitor display is black( include, everytime i refresh page) , I have to start mplayer through vnc, then “ctrl c" to cancel it. then the video is switched to the web display.

Ben Curtis · Answer 7 · Tue Oct 30 2018 23:35:34 GMT+0800 (China Standard Time)

What is in your /etc/ipmi.conf? And have you tried sending keypresses from the command line (see README)?

bingrui pan · Answer 8 · Thu Nov 01 2018 15:24:48 GMT+0800 (China Standard Time)

yes, I send command from Pi0 to the machine is ok (screen usb0).
but not able to send from web page, not familly with php.
/etc/ipmi.conf
[Server 1]
TTY=/dev/ttyUSB0

Ben Curtis · Answer 9 · Thu Nov 01 2018 22:05:53 GMT+0800 (China Standard Time)

OK, that's good then. Something is probably showing up in the PHP logs. Can you tail them while attempting the commands? And just to be sure, you are "typing" on the webpage, not "clicking" on the letters, right?
