ffmpeg - escaping single quotes doesn't work [duplicate]
18 septembre 2022, par XorOrNorI've written a small python script for mass converting audio files. It uses ffmpeg. The problem is it doesn't work for files with single quotes in their filenames.


script :



import os
import subprocess
import sys
from multiprocessing.pool import ThreadPool as Pool

source_dir="/home/kris/Music/test"
output_dir="/home/kris/Music/test_opus"

def worker(file):

 try: 
 dirname=os.path.dirname(file)
 file=file.replace("'","\\\\'")
 filename=file.split('.flac')[0]
 
 input_file=f"'{source_dir}/{file}'"
 output_file=f"'{output_dir}/{filename}.opus'"
 cmd="ffmpeg -n -i "+input_file+" -c:a libopus -b:a 320k "+output_file
 print(cmd)
 result = subprocess.call(cmd,stdout=subprocess.PIPE,shell=True)
 except:
 print('item error')
 

def start(): 
 threads=os.cpu_count() 
 pool = Pool(threads)
 files=os.listdir(source_dir)
 for item in files:
 pool.apply_async(worker, (item,))

 pool.close()
 pool.join()
 
start()



Testing :


- 

-
Filename :
I'm a file.flac

-
When escaping single quote
'with double backslashes\\-file=file.replace("'","\\\\'")the cmd for ffmpeg is :







ffmpeg -n -i '/home/kris/Music/test/I\\'m a file.flac' -c:a libopus -b:a 320k '/home/kris/Music/test_opus/I\\'m a file.opus'


ffmpeg returns an error :
/home/kris/Music/test/I\\m: No such file or directory

- 

- When escaping single quote
'with a single backslash\-file=file.replace("'","\\'")the cmd for ffmpeg is :




ffmpeg -n -i '/home/kris/Music/test/I\'m a file.flac' -c:a libopus -b:a 320k '/home/kris/Music/test_opus/I\'m a file.opus'


I got an error :


/bin/sh: 1: Syntax error: Unterminated quoted string


According to ffmpeg docs : https://ffmpeg.org/ffmpeg-utils.html#toc-Examples escaping with single backslash should work.
