• How can I save the downloaded and converted audios to a specific folder

  19 décembre 2022, par Retire Young

  I'm trying to download Videos from a specific playlist and converting it to a m4a file for further downloading. The process works perfectly but the files are being saved in the same folder where my Phyton script is located. I choose a specific Output Folder but the files don't appear there.
Any ways to save the files in the desired folder ?

  


  An error message reads as follows : "input.mp4: No such file or directory"
In my Code block, I censored the playlist link and the user name on the path. Just imagine a working playlist link instead. Thanks in advance !

  


  import os
import subprocess


  


  Replace with the URL of the YouTube playlist

  


  playlist_url = "PLAYLISTLINK"

  


  Set the output directory for the downloaded files

  


  output_dir = "/Users/USER/Documents/VideoBot/Output"

  


  Use youtube-dl to download the latest video in the playlist

  


  subprocess.run(["youtube-dl", "-f", "bestaudio[ext=m4a]", "--playlist-start", "1", "--playlist-end", "1", playlist_url])

  


  Extract the audio from the downloaded video using ffmpeg

  


  subprocess.run(["ffmpeg", "-i", "input.mp4", "-vn", "-acodec", "copy", "output.m4a"])

  


  Move the extracted audio file to the output directory

  


  os.rename("output.m4a", os.path.join(output_dir, "output.m4a"))

  


• ERROR : opus not found using pkg-config in msys64 on Windows

  10 août 2022, par prostargamer

  I'm trying to build ffmpeg.

  


  I downloaded msys2 x64 from the official website. This is the latest version.
  
Executed "pacman-Syu", rebooted msys and executed "pacman-Su".

  


  In your file build_ffmpeg_win.sh ffmpeg installs the following packages using pacman :
  

  


  pacman --noconfirm -Sy
pacman --noconfirm -S msys/make
pacman --noconfirm -S mingw64/mingw-w64-x86_64-opus
pacman --noconfirm -S pkg-config
pacman --noconfirm -S diffutils
pacman --noconfirm -S mingw-w64-x86_64-pkg-config


  


  Then I run "pacman -Qet" in order to get the list of packages :

  


  $ pacman -Qet
base 2020.12-1
diffutils 3.8-1
make 4.3-1
mingw-w64-x86_64-opus 1.3.1-4
pkg-config 0.29.2-4


  


  The opus package is installed.

  


  However, when I try to run "build_ffmpeg_win.sh", then I get the following error at the stage ./configure : "ERROR : opus not found using pkg-config"

  


  The following folders and files are located in the "msys64\mingw64\lib" folder :

  


  pkgconfig (folder)
libopus.a
libopus.dll.a


  


  There is an opus.pc file in the msys64\mingw64\lib\pkgconfig folder, the contents of which refer to /mingw64/lib and /mingw64/include.
pkg-config knows about opus, but for some reason this error occurs during ./configure.

  


  How can I solve this problem ?

  


• pyInstaller : Pack binary executable inside project's executable to run

  18 décembre 2023, par zur

  TLDR ;

  


  I would like to pack the ffmpeg executable inside my own executable. Currently I am getting

  


  FileNotFoundError: [Errno 2] No such file or directory: 'ffmpeg'
Skipping ./testFile202312061352.mp4 due to FileNotFoundError: [Errno 2] No such file or directory: 'ffmpeg'


  


  Details :

  


  I am creating executable file using following command :

  


  pyinstaller cli.py \&#xA;  --onefile \&#xA;  --add-binary /Users/<machineuser>/anaconda3/envs/my_env/bin/ffmpeg:bin&#xA;</machineuser>

  


  The code that uses ffmpeg is not authored by me. And I would like to keep that part the same.

  


  When I run from command line while conda environment is active I can successfully run it as python (or perhaps anaconda) knows where the binaries are. I have a pretty empty cli.py. That seems to be the entry point and I hope if it is possible I can set the bin directory's path there ...

  


  I am able to successfully run the application like following :

  


  (my_env) machineUser folder % "dist/cli_mac_001202312051431" ./testFile202312061352.mp4


  


  I would like to run like following :

  


  (base) machineUser folder % "dist/cli_mac_001202312051431" ./testFile202312061352.mp4


  


  I would like to keep the world out side my executable's tmp folder the same. I would not want to change something that will be "left behind" after the exec is terminated.

  


  Question :

  


  Can some one please mention how to modify the pyinstaller command or what to change in cli.py to achieve it successfully ?
