CallCmd() by StainlessS

CallCmd(clip,string "Command"="", string "Frames"="",string "Insert"="",int "Digits"=6,bool "Once"=true,int "Offset"=0,
bool "Hide"=false,bool "Debug"=false,string "Open"="",string "Close"="",int "Synchronous"=7)

Command (default"")
A command string that will be executed on each frame specified by the Frames arg. Can contain a single INSERT arg character
which will be replaced by a string representing the frame number with optional OFFSET. If the command naturally contains the
INSERT character then choose a different INSERT charcter or use two INSERT characters in the Command string to escape it
(one of them will be removed in the executed command).

Frames (default "")
String to specify the frames upon which the COMMAND arg is executed.
Comments beginning with '#' can occur in the FRAMES arg, SEMICOLON Cannot be used in a comment.
SEMICOLON ";" or NewLine [Chr(10)] is used as a frame specifier terminator.
COMMA "," specifies a frame range where the 2nd range end number can be '0' meaning last frame, and eg '-4' meaning 4 frames.
"0,0" Specifies ALL frames.
Example:
FRAMES="
1 # This is a comment, calls on frame 1.
3;5;7 # Calls on frames 3 and 5 and 7, SEMICOLON is SOFT End Of Line and terminates any COMMENT.
8 # Call Frame 8 ; 10 # *** IMPORTANT *** And because of SEMICOLON also calls on Frame 10.
14,16 # Calls on frames 14 to 16, COMMA specifies a frame range.
18,20;22 # Calls on Frame range 18 to 20 and frame 22.
24,-4 # Specifies frames 24 to 27, ie 4 frames starting at frame 24.
"

Insert (default "")
Single character which will be replaced in the Command arg string by frame number + OFFSET arg.
If the command naturally contains an INSERT character then choose a different INSERT arg charcter or use two INSERT characters
in the Command string to escape the naturally occuring one (one of them will be removed in the executed command).

Digits (default 6)
Minimum number of digits generated in inserted text that replaces the INSERT character in the COMMAND arg.

Once (default=true)
If true then only executes frame commands once on each frame, if replayed, does not exec 2nd time.

Offset (default 0)
Offset added to frame number when generating text inserted into a frame command replacing the INSERT character.

Hide (default false)
If true, hide black console window on command execution.

Debug (default false)
If true, sends debug info to DebugView Window.
DebugView (Highly recommended, allows viewing of info and warnings from the plugins and other programs)
http://technet.microsoft.com/en-gb/sysinternals/bb545027

Open (default "")
Command executed on plugin start up (Constructor), before first frame.
No string replacements, ie INSERT, DIGITS and OFFSET have no effect.

Close (default "")
Command executed on plugin close down (Destructor), after last frame.
No string replacements, ie INSERT, DIGITS and OFFSET have no effect.

Synchronous (default 7, range 0 - 7)
The Synchronous arg is a group of 3 bitflags,
bit 0 if set means wait for process to terminate before returning from the 'Open' command.
bit 1 if set means wait for process to terminate before returning from the 'Frames' commands.
bit 2 if set means wait for process to terminate before returning from the 'Close' command.
0 = All Asynchronous, ie dont wait at all.
1 = Wait only on 'Open' command.
2 = Wait only on 'Frames' commands.
3 = Wait on 'Open' and 'Frames' commands.
4 = Wait on 'Close' command.
5 = Wait on 'Open' and 'Close' commands.
6 = Wait on 'Frames' and 'Close' commands.
7 = Wait on ALL commands (default).

Beware, if you dont wait it is very possible that any future reliance upon output of command may fail due to the
output file being in use. Also, if debug true and waiting for process to complete, then will also show the process return
code on successful process creation (and completion) in DebugView, cannot do this if NOT waiting completion.

-----------------------------------------------------------------------------

CallCmd, does NOT replace single quotes with double quotes in Command string, was source of problems in Call().
Instead wrap eg filenames containing spaces in double-quotes using perhaps:

Function QuoteStr(String s) { return Chr(34) + s + Chr(34) }

or use triple and single double-quotes eg

CallCmd(BlankClip,Close="""d:\nicecho.exe @d:\report.txt "Appending" """)

---
Executing on each playing, on every frame, hiding console window, sending debug info to debugview, and converting
command string on frame eg 0 to "C:\PortableApps\ImageMagick\Mogrify.exe -flop C:\Temp\000000.tif"

CallCmd(clip,"C:\PortableApps\ImageMagick\Mogrify.exe -flop C:\Temp\#.tif", "0,0",Insert="#",Once=false,Hide=true,Debug=true)



At Open, executes delete on wildcard files silently, without asking confirmation.
CallCmd(Open="""cmd /c DEL /Q "C:\TEMP\test_*.tif" """)

To execute DOS type commands, in DOS console type "cmd /?" for cmd options, and eg DEL /? for delete options.

Works OK, deletes every frame after use and just before frame delivered to eg VDUB, no scriptclip.
Tried going backwards and jumping about, seems to still work without problems and no images left in TMPDIR.
If you set up a RAMDISK for temp files/file (and perhaps imagemagick), it might fly like a bat out of hell, then again it might not.
RAMDISK.SYS or similar, http://en.wikipedia.org/wiki/List_of_RAM_drive_software).
Would be interested in hearing if it made much (if any) difference.

EDIT: Actually, the DEL command seems to take quite a bit of time to execute, perhaps CMD.exe would need to be on ramdisk too,
or a better, a lightweight DEL type command obtained. It's disappointingly slow compared to the figures you gave for scriptclip
version, dont know why yet.

EDIT: See RT_Stats RT_FileDelete().

[martin53]

StainlessS,
hope you don't mind that I respond so late. I'm very much involved in my daytime job and the frame substitution filter. Same will apply in the future, i'm afraid.

Does C++ offer a "wait for return" switch for a shell call? With Visual Basic Script shell calls, I know such a switch.
I never mentioned it before, because all Calls I could imagine would not reasonably continue before the shell command was executed. But it's a different thing with the DEL command. That could well be finished asynchronously.

[StainlessS]

CallCmd waits for the process to both start and end (as Call did), I guess I could add an arg to return immediately,
It might well be the CMD.Exe that is slow to start though, I know it checks eg AutoRun type entries
in the registry and probably an amount of other startup stuff. (CMD /D disables AutoRun).
I'll add the arg soon.


EDIT: RAMDISK dont seem to be beneficial, guess that the ScriptClip single tif version is hitting the disk cache
all of the time and therefore gives better performance.

[jmac698]

What would be really cool is to call an external program on frames and be able to return an image. There are some pretty cool filters (research) that you could call that only work on one frame. Usually they only support one frame or simple bmps. There are a lot of extra steps to make them process video. Being able to simply embed a command line to serve frames to external image processing would be amazingly easier.

I think it's quite easy to code; just read out the current frame in a loop and write it as a temp file as a BMP (the format is quite simple to do), call the command, the command does "process -i in.bmp out.bmp" and have the program wait, then read out.bmp and return that to Avisynth. If you have everything setup for development, it's just a few more lines of code; except writing the .bmp part, but I've done that by hand, you can copy the header from any existing file and just change the width and height and file length values. All I remember is it starts with BM :)

One more feature, I might need at least 3 passes so next version have option to send each plane as separate calls (either r,g,b or y,u,v)

Oh you know how nice that would be.. instead of fiddling with command lines and loading the results in an image viewer, it can all be done in AvsP with instant preview, all it's features for script editing, user sliders! It's like istant gui for cmd line.

[StainlessS]

CallCmd() v1.01, New version, added 'Synchronous' arg.

@Jmac, oops you just clipped me.
Think that the suggested plug would be another filter.

a command line to serve frames to external image processing would be3 amazingly easier

I look forward to it with baited breath. :)

EDIT: I dont really see it as being any great improvement over using ImageWrite/CallCmd/ImageRead combo, just
a lot more work for YOU. ;)

Oops, someone had that idea... what's this "ScriptClip single tif version"

@Martin53,
trust you saw the MDepan stuff in RT_Stats (last post), together with the StrReplace problem that you would encounter

Can any DOS wizard assist here ?

What I want to do is execute a line like this


C:\WINDOWS\system32\cmd.exe /K "C:\BIN\ffprobe.exe -i D:\AVS\AVI\TEST.VOB"


Where

"C:\WINDOWS\system32\cmd.exe" is the DOS CLI

/K means keep console window open on completion (will eventually use /C ie close on completion)

"C:\BIN\ffprobe.exe -i D:\AVS\AVI\TEST.VOB" is command to be executed by the DOS CLI together with args for target executable.

What I want is to redirect output from ffprobe (written to DOS CLI console window via stderr or stdout) to a file,
is there a way to redirect output from a NON DOS command (DOS COMMAND being eg DIR) where the NON DOS
command does not provide a way to accomplish same thing.

thanks in advance :)

[martin53]

I don't own ffprobe.exe . But generally the job split is like this:
- All executables should write to the streams stdout, stderr etc., i.e. this is not restricted to cmd.exe-internal commands.
- Cmd.exe allows to redirect or pipe stdout to a file with the '>' operator overwriting or '>>' appending.

There is a Syntax '2>' to redirect "stream 2" stderr: Try 'NonexistentCommand 2>test' at the command line. The file 'test' will contain cmd.exe's error message.

You sure tried
'C:\WINDOWS\system32\cmd.exe /K "C:\BIN\ffprobe.exe -i D:\AVS\AVI\TEST.VOB" >Path\File'. What did happen instead of the expected behaviour?

EDIT: Many old compiler packs contained a program TEE.EXE. You pipe any program's output to TEE and give TEE a file name. TEE mirrors its input to both stdout and the file.

Use this:

C:\WINDOWS\system32\cmd.exe /K "C:\BIN\ffprobe.exe -i D:\AVS\AVI\TEST.VOB 2> file.txt"


P.S. Please don't refer to the NT CLI as "DOS". :rolleyes:

[martin53]

Cmd.exe does not expect everything after /C or /K to be one quoted string.
C:\WINDOWS\system32\cmd.exe /K C:\BIN\ffprobe.exe -i D:\AVS\AVI\TEST.VOB 2> file.txt
should work as well, and also
C:\WINDOWS\system32\cmd.exe /K C:\BIN\ffprobe.exe -i "D:\AVS\AVI path with spaces\TEST.VOB" 2> "D:\Output path with spaces\file name with spaces.txt"

[StainlessS]

Dang but you are correct.
Had already tried same but failed, musta screwed up somewhere and thought it down to cmd.exe needing executable string at END of line
(according to "CMD /?").

Thank you.

EDIT:

P.S. Please don't refer to the NT CLI as "DOS". :rolleyes:

I consider my bottom, justly smacked :)

[Groucho2004]

Cmd.exe does not expect everything after /C or /K to be one quoted string.
Typo, sorry. I'm sure Stainless figures it out.

I don't own ffprobe.exe

ffprobe.exe is part of ffmpeg, although may not always come with all packages.

Using string to CallCmd (EDIT: well actually RT_Call, but almost same thing)

C:\WINDOWS\system32\cmd.exe /K "C:\BIN\ffprobe.exe" -i D:\AVS\AVI\TEST.VOB 2> D:\AVS\AVI\TEST.TXT


obtains this in TEST.TXT

Quotes around both input and output files but not about ffprobe.exe, if ffprobe.exe path changed to "D:\A V S\AVI\"
then fails, could not find any combination of single/triple quotes that worked for all three paths.

EDITED:
One of the problems is that, enclosed in quotes, ffprobe complains about it's own file name being supplied as an arg to ffprobe,
perhaps it is only an ffprobe problem, and not a general prob.

[martin53]

Just updated to V1.02 as you proposed, but now cannot open my clip any more:
I just need CallCmd in destructor.
But V1.02 complains about the empty frames string and refuses to go on. Btw the V1.02 plugin has name 1.01 on mediafire - or I'm struggling with 1.01 and 1.02 was not published.

EDIT: not true. The new version complained about the other calls that were not yet corrected to the new syntax, but still read "-3" as frame identifier, instead of using the new 'Close=' parameter.

[StainlessS]

Sorry, yes v1.01 should have read v1.02, just forgot to rename the containing folder before zipping, shall re-upload now using correct name.



The new version complained about the other calls that were not yet corrected to the new syntax, but still read "-3" as frame identifier, instead of using the new 'Close=' parameter.

What script are you trying ?

EDITED:

EDIT: OOPS, now I understand, you mean your script still used old frames spec of -3, thought you meant that
the new version still worked with old spec, silly me.

[martin53]

StainlessS,
I got everything running :). I was trying to say that I used 3 calls, and only had converted one to the "close=" syntax. Therefore, the first of the other two remaining script lines produced the output you wrote: "...*NON PARSE* $-3 @ -3" - and I misunderstood this as an error message of the line I had already changed. After I also changed the other two lines, it was fine!

[vampiredom]

I simply MUST try this ... I would love to get rid of my crazy Call25Helper.exe hack. Unfortunately, I have been really short on time to test out new things. I will try this out and get back to you. Thanks, Stainless.

[StainlessS]

Vampiredom, There is also a compile/run time version in RT_Stats, not based on Frame number, Constructor, Destructor.

[vampiredom]

I finally got around to trying it, StainlessS. It works a treat. Excellent. I have no idea if this is even possible… but it there some way to have a function like this return a program's STDOUT to AviSynth as a string? That would be extremely useful.

[martin53]

return a program's STDOUT to AviSynth as a string?
What you can do today is redirect STDOUT to a file, and read the file from AviSynth. See here (http://forum.doom9.org/showthread.php?p=1653164#post1653164)

Thanks. Yeah, I already do stuff like this ... I often write Perl scripts and such that generate strings and write them out as AviSynth variables in a text file, Import() them in AviSynth, etc.

It would just be handy (and cleaner) to have AviSynth be able to read the STDOUT directly, I suppose. :)

StainlessS,
would you please help checking if there might be a new Win10-related issue.
I use a loop of AviSynth Script calls to a Thumbsheet-Creator function (http://forum.doom9.org/showthread.php?p=1710421#post1710421) to make thumbsheets of a set of clips.
The thumbsheet creator uses the ImageWriter function, and to compress the Jpegs and remove the frame number from the filename, CallCmd calls ImageMagick's 'convert' and command prompt's 'del' at the closedown of the modified script in line 63
CallCmd(Close=
\"Cmd.exe /c P:\PortableApps\ImageMagick\convert " + chr(34) + JpgName +"000000.jpg" +chr(34) + " -quality 75 " + chr(34) + JpgName + ".jpg" + chr(34) + " && del " + chr(34) + JpgName +"000000.jpg" +chr(34),
\Hide=true, Synchronous=7)
I used this regularly and without obvious flaws for many months, for a while with 32bit AviSynth+ r1779, and recently updated from Win7 (x64) to Win10.

Now I observe that the thumbsheets all need a suspicious time of exactly 30 seconds to be created, and by some random cause, the time switches to exactly 30 minutes(!) per thumbsheet.

I'm unsure if the 'synchronous' parameter might be broken in Win10, so CallCmd runs into some sort of timeout.

Will change the outmost loop to do these operations outside the AviSynth script and report more findings.

EDIT
After commenting out line in AVS script and adding the commands in the calling AU3 script, processing time is not as stable at 30" as before, and issue is still there. So seems not to come from the CallCmd line but maybe from VirtualDub (which is the portable version 1.10.4 being called directly without the 'portable wrapper' because that is not needed here) or AviSynth+ itself.

AVS script is executed from AutoIt via:
RunWait("P:\PortableApps\VirtualDubPortable\App\VirtualDub\vdub.exe " & $s2 & " /cmd VirtualDub.RunNullVideoPass(); /x", "", @SW_HIDE)

Mobile:

M53, I'm sorry, don't use/have win 10, me still happy on xp32.
Callcmd comes with source, you are perhaps best person to fix problem. If you have any questions on source then can post or PM and I'll do my best to assist.

[StainlessS]

You could perhaps try without HIDE, see if anything is waiting some keypress or something (or error message).

[StainlessS]

CallCmd v1.04, see first post.


v1.00, - 08 Oct 2012, Changed Frames spec, added Open,Close
v1.01, - 21 Oct 2012, Add Synchronous Arg.
v1.02, - 1 Jan 2013, Add error message on fail.
v1.03, , SetLastError(ERROR_SUCCESS) prior to call.
v1.04, - 3 Apr 2018, compile VS2008


Included Avsiynth v2.58, avs+ v2.6 x86, and Avs+ x64 dll's

[dani75]

Good morning everybody.
I just discovered CallCmd() (thanks to StainlessS) and I found it useful inside one of my scripts under AviSynth (still in 2.6.0) to call an executable I made. I installed the CallCmd_25_x86 library (my OS is W10 64 bits).
Unfortunately, I got a 0x00000057 issue. Therefore I replaced the original CallCmd I was working on by the following :
CallCmd(Last,Open=""" "cmd /C echo Hello world" """,Debug=True)
And I got the following on DebugView:
00000006 18.37546158 [10172] CallCmd: Constructor IN

[StainlessS]

Too many double quotes.

CallCmd(Last,Open="""cmd /C echo Hello world & pause""",Debug=True)


I've added "& pause" where "&" means new command, (ie multiple commands on single line), and "pause" to wait, so you can see it.
hit a key and it goes away.

EDIT: If you're on avs v2.60 x86, maybe should use "CallCmd_x86_1.04.dll" and rename to just "CallCmd.dll". [the one you are using is for avs v2.58]

[Groucho2004]

The intended pause does not work. EDIT: in my prev post you can see the pause, "Press any key to continue . . .".Oh, I see. I'll try to figure it out. I don't even know what this plugin is supposed to do...

Edit - It seems to work as intended with avsr.

[StainlessS]

I don't even know what this plugin is supposed to do
Plugin to execute command on selectable frames or at startup or closedown. Based on Call() by Nic.

I'll try also with avsr.

For "Hello world pt...", I was just kinda curious what the 'pt' thing stood for, presumably to represent Ampersand '&'.

EDIT: One of its main uses was to delete files prior to RT_Stats RT_FileDelete().
Also, eg call ImageMagick to operate on an image/frame, and then reload result into script + many other possibilities.

EDIT: also, can set to delete some file on clip destructor, ie delete temp files on clip/script closure.

[Groucho2004]

I'm using fputs() instead of vfprintf() in AVSMeter which is probably the problem. I made that change when some GUI capture didn't work (I think it was ripbot). I'm considering to revert that change.

[StainlessS]

(I think it was ripbot). I'm considering to revert that change.
I think was Ripbot too. [be careful not to break Ripbot, you know how emotional Atak_Snajpera can get ( :) )].

[Groucho2004]

I think was Ripbot too. [be careful not to break Ripbot, you know how emotional Atak_Snajpera can get ( :) )].Well then, maybe you can use avsr for the time being?

[Groucho2004]

I think was Ripbot too. [be careful not to break Ripbot, you know how emotional Atak_Snajpera can get ( :) )].I checked, ripbot is using a 3 year old version of AVSMeter so I think I can go ahead with that regression.

[StainlessS]
