Hello there, i am completely newbee in scriptwriting and i hope if someone could help me.

I have SX50HS and i use chdkptp to connect and control camera. I need to make a remote video. In other words i just need to press video button and release it in some time.
It works fine in gui mode of chdkptp, but i would like to automatically launch a video in a cli mode. i have been trying it about a week already.

I tried to wrote a script which press("video") and then release it, but in cli mode when i turn camera to rec mode and then tryng to execute a script (.loadfile("A:/CHDK/Scripts/Extention/video.lua")() or exec(video.lua())) cli writes "I/O error" and camera shutdown.

Now i am lack of new ideas how to fix this problem.
Hoping you will help me.
Thanks a lot anyway!

PS i also tried video50.lua script from topic: https://chdk.setepontos.com/index.php?topic=12898.0.
The result is still the same, camera is turning off and cli reports about error. Maybe i am just doing wrong with cli command to execute a script, but a have tried it many times in different syntax according to the manual.

The shutdown and I/O error means the camera crashed. A romlog might help understand what caused the crash: http://chdk.wikia.com/wiki/Debugging#Camera_crash_logs_.28romlog.29

The camera does not use a ":" in the path after the drive letter, so the command should be

Code: [Select]

.loadfile("A/CHDK/Scripts/Extention/video.lua")()

I don't know if this is the cause of your problems, but in some cases a bad path might cause a crash.

If the path issue wasn't the problem, I'd suggest trying a process of elimination. Start with a very simple script, like print 'hello world', and if that doesn't crash, start adding the other parts.

FWIW, in chdkptp you can also run a camera side script that's stored on your PC using

Code: [Select]
