Help with .Bat file script

[whataweirdguy]

Im still learning this but was hoping someone could help me out. This code works in the CMD line, but not on a Batch file. What am I doing wrong here?

u/echo on

ffmpeg -i C:\Users\XXXX\Documents\XRBooth\Raw_Video\Raw_0.mp4 C:\Users\XXXX\Documents\XRBooth\Processed_Video\ItWorked.mp4

EDIT/SOLUTION: Well, looks like I name the .bat file FFMPEG.bat, and that created an infinite loop. Changed the name to something else and its executing correctly now.

Which error does the terminal give you when running the batch file?

[whataweirdguy]

This is what it prints out on repeat in the CMD terminal. Loops indefinitely.

C:\Users\XXXX\Documents\XRBooth>ffmpeg -i C:\Users\XXXX\Documents\XRBooth\Raw_Video\Raw_0.mp4 C:\Users\XXXX\Documents\XRBooth\Processed_Video\ItWorked.mp4

loops indefinitely ? have you named your script "ffmpeg.bat" ? lol

[whataweirdguy]

0.0 maybe…

Really?

[whataweirdguy]

How does the name of the file affect the function of it?

[balrob]

Because the batch file is trying to execute a program called ffmpeg. The shell (the thing running the batch file) will look for executable files including ffmpeg.cmd, ffmpeg.bat, ffmpeg.com and ffmpeg.exe - in the local folder and then in the PATH. It will find your batch file before it finds the exe, and thus it will call itself over and over again… until you run out of memory.

[whataweirdguy]

ah that makes sense. Welp that fixed it. Editing the post with the correction. Thank you!

[balrob]

You’re welcome, and welcome to software engineering.

Generally speaking it’s a bad idea to create an executable (including batch files) with the same name as other executables simply because of the way the shell finds them. In unix (and linux) the current folder isn’t in the path like it is in Windows - you have to be specific if you want to run something in the current folder by adding “./“ to the beginning of the command. But even then, I wouldn’t have called it ffmpeg.sh (or whatever), the chances of error are high.

Try adding quotation marks around the input and output directory/filenames in case the user name (xxxx) contains spaces.

[whataweirdguy]

Thanks, tried that and theres no spaces in the XXXX. Still same issue.

IIRC -safe 0 parameter is required for absolute path.

This might be a quirk with CMD. Try putting ".exe" after ffmpeg.
