  • Change youtube-dl download output (Windows)

    13 avril 2016, par Inforcer25

    I hope you can help me.

    I am using youtube-dl on windows (youtube-dl.exe)
    Downloading the video works great and also just the audio. But what i want is for it to save the audio file in a different place eg. C :\Users*******\Desktop

    I made a batch file with this code :

    :audio
    
cls
    
echo.
    
echo.
    
echo Your audio vill be downloaded and saved as a .mp3 format
    
echo.
    
echo.
    
set /p audio=Enter Video URL here:
    
cls
    
youtube-dl.exe --extract-audio --audio-format mp3 --output C:\Users\*******\Desktop\(ext)s.%(ext)s %audio%
    
pause
    
cls
    
echo.
    
echo.
    
echo.
    
echo.
    
echo Your audio has now been downloaded.
    
ping localhost -n 3 >nul
    
exit

    and then it gives me this

    Usage: youtube-dl.exe [OPTIONS] URL [URL...]
    

    
youtube-dl.exe: error: You must provide at least one URL.
    
Type youtube-dl --help to see a list of all options.
    
Press any key to continue . . .

    It works fine if i use this but it saves it in the same folder.

    :audio
    
cls
    
echo.
    
echo.
    
echo Your audio vill be downloaded and saved as a .mp3 format
    
echo.
    
echo.
    
set /p audio=Enter Video URL here:
    
cls
    
youtube-dl.exe --extract-audio --audio-format mp3 %audio%
    
pause
    
cls
    
echo.
    
echo.
    
echo.
    
echo.
    
echo Your audio has now been downloaded.
    
ping localhost -n 3 >nul
    
exit

    Also please keep in mind that it also uses ffprobe.exe and ffmpeg.exe (They are both in the same folder as youtube-dl.exe

    when i execute buid_android.sh script without —enable-libx264 \ line everything is going well and i can get .a files on android/arm/ folder. but with this line it fails and show the following error in the console :

    If you think configure made a mistake, make sure you are using the
    latest version from Git. If the latest version fails, report the
    problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on
    irc.freenode.net. Include the log file "config.log" produced by
    configure as this will help

    it seems like it can’t find where the libraries are, as i get a lot of the following errors in config.log file :
