Batch file question

[theredbaron]

Sounds like the problem is, AutoXVid.exe's isn't a "blocking" program. It's main thread may return control before the operation is complete.

Does AutoXVid.exe actually make use of stderror? It could be that every time the EXE executes it returns a code, indicating its current status. Which you could check, in a loop

Does AutoXVid.exe generate an output file? It seems that it does. Can you test for that? You know, if not exist whatever.txt goto keeptrying?

Are those actual commands i can throw into the batch ('if not exist' / 'goto' / 'keeptrying')?

Si senor. To wit, fire up Ye Olde Notepad and type in the following:

Code:

@echo off

:tryagain

echo Still waiting...

if not exist whatchoodoinhere.sem goto tryagain

pause

Save the file as test.cmd. Or test.bat, if you swing that way. No matter. Now double-click it. Watch the message scroll endlessly in the console window. Leave the console window open. Let it scroll.

Now, in the same folder, right-click and select New->Text Document. Rename it to whatchoodoinhere.sem. Notice the scrolling list in the console window has paused. No, it's not magic! It's a legacy batch processing syntax interpreted by cmd.exe (The Artist Formerly Known as command.com). You might find this topic useful.

@echo off

:tryagain

echo Still waiting...

if not exist whatchoodoinhere.sem goto tryagain

pause

Although maybe not the cleansest way, this will work. However, this can result in 100% cpu. I would just add a sleep call in the loop (even only 1 or 2 seconds), this will make it more sane.

I use this in PostProcessing.bat to check if the video is in use (by comskip, or just being watched) before doing other stuff...

Code:

:rename
timeout 30
move "%~dpnx1" "%~dp1-%~nx1"
if %ERRORLEVEL% == 1 goto rename:
move "%~dp1-%~nx1" "%~dpnx1"
REM RenameRecording -t %1 > rename.log

I posted a link to "timeout.exe" in this thread.

It will work? For what? Showing someone an example of the if syntax? You know, it just might...lol.

However, this can result in 100% cpu.

Is that the new one from AMD?

Sane? No comment. lol

But sleep.exe...yes, good old pointless sleep.exe. I wonder if a little Microsoftie got brownie points for "creating" that unnecessary utility.


Use this instead. Impress your friends:[INDENT]ping -n 6 127.0.0.1 > nul

[/INDENT]That'll pause your batch file for 5 seconds. Very politely. Does other cool stuff too.

EDIT

Maybe you should just stick to posting stuff that may be of help to people.
I've read many of your posts and a lot of them border on flaming people.
I don't think the gbpvr community needs that.

Do you always sound like a d*ck or just in your posts?

I don't know. But I'm usually right. Not always, but usually. So who cares what I sound like?

I prefer a falsetto "a la Sting" when I sing, but that's only because I don't have the pipes to stay on key in the lower registers. Unless I'm in the shower. Now that thing is magical, that shower. I can sing like a nightingale in there. But with words, of course. And you know, actual songs.

But whistling in the shower...hmm...it hadn't occurred to me.

Honestly though, if you're a serious tinkerer and you want to do cool pre- or post-processing stuff that's launched from batch files or whatever, Windows Scripting is the ticket.

But if people want to use batch files, I'll help them out. The ping method I described above doesn't require any non-standard stuff. You don't have to worry about finding sleep.exe somewhere and putting it in your path or anything.

Oh, and as a sort of post script: It's a forum on the Web. You can't see me smiling as I chug my Newcastle getting ready to head out for the evening. If you promise to take me with a grain of salt, I promise to keep helping out. Deal? :-)

So I've got a little personality? Heaven forbid!

I also have a tremendous amount of relevant programming knowledge and experience, and I like this project. And I want to help out. It's a simple system that works really well despite itself. I love that!

I hope for the sake of sub (and whoever else) that it continues to grow and improve. It's become a staple on my kids' computers. So just deal, mmmkay?

I appreciate your help guys. I will try all these things this weekend. I might also try StaxRip (which has native command line support) to transcode

Let us know how it goes.
Assuming the file is in-use while being transcoded, post #14 is a working solution for your direct question.
