• Bash script for re-encode file if re-encoded file does not already exist for all in directory

  25 octobre 2022, par steve

  I have a bash script that takes 1 argument (a file) and runs an ffmpeg command to create a duplicate of the file encoded with a different codec.

  


  #!/bin/bash

ffmpeg -i "$1" -vn -acodec aac "$(basename "${1/.wav}").aac"


  


  I just want to modify this bash script so instead of taking an argument, it instead just checks for all files in the directory to see if the re-encoded file already exists, and if it does not, creates it. Does anyone know how to do this ?

  


  Thanks for your help

  


  EDIT : the solution below is working with slight modification :

  


  #!/bin/bash

for file in ./*.wav; do
    [ -e "$file" ] || continue # check if any file exists
    if [[ ! -f "${file}.aac" ]]; then
       ffmpeg -i "${file}" -vn -acodec aac "$(basename "${file}").aac"
    fi;
done;


  


• .exe file, works different than .py file

  29 août 2024, par r_b

  I've made the YouTube Dowbloader App. Everything is working properly (run in PyCharm), but when I try to make it into an executable with pyinstaller, it does not work.

  


  This is the link to the repo :

  


  YouTube Downloader

  


  Command for making exe file :
pyinstaller project.spec

  


  project.spec file :

  


  # project.spec
# -*- mode: python ; coding: utf-8 -*-

block_cipher = None

a = Analysis(
    ['gui.py'],
    pathex=['.'],
    binaries=[],
    datas=[('static_files/*', 'static_files')],
    hiddenimports=[],
    hookspath=[],
    runtime_hooks=[],
    excludes=[],
    win_no_prefer_redirects=False,
    win_private_assemblies=False,
    cipher=block_cipher,
)
pyz = PYZ(a.pure, a.zipped_data, cipher=block_cipher)

exe = EXE(
    pyz,
    a.scripts,
    [],
    exclude_binaries=True,
    name='YouTube Downloader',
    debug=False,
    bootloader_ignore_signals=False,
    strip=False,
    upx=True,
    upx_exclude=[],
    runtime_tmpdir=None,
    console=False,
    icon='static_files/logo.ico'
)
coll = COLLECT(
    exe,
    a.binaries,
    a.zipfiles,
    a.datas,
    strip=False,
    upx=True,
    upx_exclude=[],
    name='YouTube Downloader'
)

app = BUNDLE(
    coll,
    name='YouTube Downloader',
    icon='static_files/logo.ico',
    bundle_identifier=None
)


  


  The file structure :

  


  project/
├── backend.py
├── gui.py
├── temp_mp3 # temporary mp3 for Audio player
├── static_files/
│   ├── icon.ico
│   ├── image1.png
│   ├── image2.png
│   └── setup.json  # setup.json file
└── project.spec

  After searching and fetching the YouTube URL, the app downloads an MP3 file (in temp_mp3) for the audio player section.

  


  And here is the difference between .exe and the .py, when I run .exe the APP downloads the audio segment from the URL in .webm format and stops there. Even if the format is different, it should be converted to MP3 (in PyCharm does).

  


  Find possible problem with moviepy/ffmpeg.exe (library for converting files).

  


  project.spec

  


  a = Analysis(
    ['gui.py'],
    pathex=['.'],
    binaries=[('C:\\path\\to\\ffmpeg\\bin\\ffmpeg.exe', 'ffmpeg')],
    datas=[('static_files/*', 'static_files')],


  


  Added binaries => path to ffmpeg.exe , but it still doesn't work.
