Extracting audio to files with different names

[civilwargeeky]

Hello! So I am using youtube-dl in a larger application. This application keeps track of song names, and calls youtube-dl using subprocess.call likesubprocess.call("youtube-dl.exe "+options,shell=True) in a thread that I made. This works fine, the first time. If I change the file name of an output song, ffmpeg crashes and fails to process the song.

Here is my program output (run 1, file name: Testing1)

Hmm... Upon further investigation it seems only to happen with files that I had previously deleted in testing. For example naming the file "Testing6" resulted in no error, though it seems to be somewhat random. It may be some error with ffmpeg and not youtube-dl

After thinking about it today, I realized this bug is probably due to my testing in a coding environment hardlinked to be synced by Dropbox, and the files weren't being "fully" deleted as far as the operating system was concerned for a while after deletion.
I tested this by moving the program to another directory, and confirmed.
Sorry for wasting any time. My sleep-deprived self of course thought it was the utility I was using :P
