Anyway, it works with two cameras. Tested it for around 50 photos in a row without any issues.
I figured out that I can set a custom save folder by changing the command line folder to the desired location before starting interactive mode and rsint.
Yes, most of the normal remoteshoot options should work with rsint.

In chdkptp changeset 482 I improved the timeout behavior. It now defaults to 60 seconds, and can be adjusted using the -cmdwait option to rsint.  So
 rsint -cmdwait=5
will time out after 5 seconds.

When it does time out, the camera script will end and rsint will exit the next time you enter something.

You must update extras/rsint.lua and chdku.lua to use this. You also need to update your CHDK build to 3342 or later.

I updated and it is working. I first tried setting a custom save path once in rsint mode like this
Code: [Select]
s 'C:\test\file'But that freezes chdkptp and the camera. I can press the shutter button on the camera to escape the freeze. But no file is saved to the target location.

Then I realized that the folder goes as parameter to rsint, like so
Code: [Select]
rsint C:\testThat works and saves each image with the filename format IMG_3410, IMG_3411, etcetera in the folder C:\test

After I ran the test , I was wondering if it was possible to run the test from chkptp and how to do it. ( including the settings of the camera )

Further to my question I ran into a problem
Here is the log of the command  loadfile("A/CHDK/SCRIPTS/MF_TEST.LUA")()
For this to work, you need to set the menu parameters (a, b, c etc) before calling the script. Anyway, waterwingz script isn't designed to work in ptp, so other things might go wrong too.

It's not obvious to me why playing the dump failed.

Thanks for the answers.

Running the script in ptp was an interesting experiment to test the frame dump , display and "extract".

Since playing the dump succeeded after a PC reboot  and when  the camera was now longer connected , it may not be an important issue .

reyalp, is it possible to later on add a parameter for custom filenames for each image by passing parameters to each individual "s" command?

That's a good idea, I'll see if I can find a reasonable way of doing it.

I was trying to connect to a A2200 chdk build  1.3.0.3152 and chdkptp build r438
using a .bat file
"chdkptp.exe" -g -c -r="C:\Users\exavue\Desktop\reader\rs.lua"
where  rs.lua is :
rec
rs
quit

The connect fails when executed with the batch file but succeed when executed from the console .

Any clue on the source of the problem.

Thanks

The connect fails when executed with the batch file but succeed when executed from the console .
A few things:
1) What does "connect fails" mean? What actually happens?

2) Are you sure that this fails when run as a batch file, but works from the command line? I think the above should not work at all, whether from a batch file or command line. -r is processed before the connect option, and before the GUI is fully started. Processing it before the GUI is intentional, so you can set settings that need to set before the GUI is started. Doing it before the connect may be a bug, but in the case of the GUI, the connect should happen only after the GUI is started. The -r and .chdkptprc functionality is mainly intended for settings.

You can get around this using the "source" command with -e, like
chdkptp -g -c -e="source C:\Users\exavue\Desktop\reader\rs.lua"

or simply by using multiple -e commands for each command.

edit: I guess by "bat file" you maybe meant the -r option, not a .bat file?

3) Note that quit doesn't actually quit in the gui, so it will stay open. This is a bug. You could get around this using lua code to tell IUP to quit. You could use !os.exit() but I'm not sure everything would be cleaned up normally.
edit: actually quit works in the GUI if typed in the input, but not in a command file or -e command.

4) If you just want to run a command and quit, starting the GUI probably isn't a good idea, even if it worked, it will just slow things down. Just take the -g out of your command.

5) The file you run with -r is not a lua file, it's a chdkptp command file. chdkptp doesn't care what extension you use, but calling it .lua might confuse someone, or be a sign of confusion.

6) Using rec when you are already in rec mode is an error, so if you ran this multiple times without switching back to play, it would fail after the first one. There is supposed to be a setting to ignore errors, but I haven't implemented it yet.

The CLI commands aren't meant for heavy duty scripting, you can use Lua for that.

I modified the bat as suggested first  by removing the call to GUI second by using e instead of r :
1)----------------------------
if rssansg.bat is :

"chdkptp.exe"  -c -r="rs.lua"

if rs.lua is :

list
rec
rs
quit

then

rssansg.bat execution gives :

chdkptp.exe"  -c -r="C:\Users\exavue\Desktop\reader\rs.lua"

Note: The GUI is very useful to monitor the image ( and debug )

It seems to me there is a timing problem .
When the CHDKPTP commands are typed from the console in the GUI , it works but then they are included in the "rs.lua"  , the "connect" command may not not have the time to complete before the next command tries to execute.
Update : it seems to be true also for the "rec" command in the rsconnect.lua example

If the quit actually worked, you'd never have a chance to see it. While a command file is being run, you probably can't interact with the GUI, and the live view wouldn't update until it's finished.

I have no idea why a batch file would behave differently from typing the commands in a command prompt.

I'll look into these issues if I get a chance, but as I said I never intended cli command files to be used for serious scripting. You would probably be better off doing this kind of stuff in Lua.

If you can explain what you are actually trying to do, I might be able to suggest better approaches, or tell you whether it is possible.

I want to build a series of high level commands stored as a batch file to control the camera from the PC
by example : {connect , rec , remoteshoot ,disconnect }
{connect , rec , video , download }
{connect,liveview}
then I can display the image or the video  on the PC screen .

updates:

1)the problem is :
with the batch file , the command has not the time to finish its task before the next command is issued , hence the error message.


2)the PC OS is Windows 7 or higher.

3)the time necessary for a specific command to complete its task is "variable"
