  • Batch Script to Download Video with youtube-dl and Convert with FFmpeg

    24 octobre 2019, par Matt McManis

    I’m trying to

    1. Using a single batch script to
    2. Download an mp4 video using youtube-dl
    3. Save the video’s original title to a batch variable
    4. Convert the video to webm with FFmpeg

    I want to keep the original title, so it needs to read the title with youtube-dl, save it to a variable, and use that variable for FFmpeg input/output filename.

    CMD Batch

    1. Download Video

    youtube-dl -f best "https://www.youtube.com/watch?v=TWNhqCHw0qc" -o "C:\Users\Matt\Downloads\%%(title)s.mp4" --merge-output-format mp4

    2. Download Video using Loop

    This is used to save the title to a variable %%a.

    for /f "delims=" %%a in ('youtube-dl -f best "https://www.youtube.com/watch?v=TWNhqCHw0qc" -o @"C:\Users\Matt\Downloads\%%(title)s.mp4" --merge-output-format mp4') do (echo example)

    3. Final Script
    Download Video, Save Title, Convert with FFmpeg

    Sorted

    for /f "delims=" %%a in ('
    
    youtube-dl 
    
    -f best "https://www.youtube.com/watch?v=TWNhqCHw0qc" 
    
    -o @"C:\Users\Matt\Downloads\%%(title)s.mp4" 
    
    --merge-output-format mp4
    
    ')
    

    
do (ffmpeg -y 
    
    -i "C:\Users\Matt\Downloads\%%a.mp4" 
    
    -c:v libvpx -b:v 1300K -crf 16 -pix_fmt yuv420p 
    
    -map 0:v:0? -sn 
    
    -c:a libvorbis -q:a 6 -ac 2 -map 0:a:0? 
    
    -f webm
    
    "C:\Users\Matt\Downloads\%%a.webm"
    
    )

    Inline

    for /f "delims=" %%a in ('youtube-dl -f best "https://www.youtube.com/watch?v=TWNhqCHw0qc" -o @"C:\Users\Matt\Downloads\%%(title)s.mp4" --merge-output-format mp4') do (ffmpeg -y -i "C:\Users\Matt\Downloads\%%a.mp4" -c:v libvpx -b:v 1300K -crf 16 -pix_fmt yuv420p -map 0:v:0? -sn -c:a libvorbis -q:a 6 -ac 2 -map 0:a:0? -f webm "C:\Users\Matt\Downloads\%%a.webm")

    Error

    Before the script can ever reach FFmpeg, youtube-dl fails to download the file. It says the file has already been downloaded, even when there is no file in the directory.

    [download] @C#\Users\Matt\Downloads\Color Balloons.mp4 has already
    been downloaded
