  • bash loop through list of file paths - characters get removed when sending to ffmpeg [duplicate]

    9 octobre 2018, par Brad Johnson

    This question already has an answer here :

    I have a text file that contains a list of paths to flac files I want to convert to wav. Here is a small section of it :

    /mnt/nfs/Music/Rob D/1995 - Clubbed To Death/Rob D - 02 - Clubbed To Death _Kurayamino Variation_.flac
    
/mnt/nfs/Music/Blonde Redhead/2000 - Melody of Certain Damaged Lemons/11 - For the Damaged Coda.flac
    
/mnt/nfs/Music/I Monster/2001 - Daydream In Blue/01 - Daydream In Blue.flac
    
/mnt/nfs/Music/Moby/2002 - Extreme Ways/01 - Extreme Ways.flac
    
/mnt/nfs/Music/RJD2/2002 - Deadringer/01 - The Horror.flac
    
/mnt/nfs/Music/RJD2/2002 - Deadringer/03 - Smoke & Mirrors.flac
    
/mnt/nfs/Music/RJD2/2002 - Deadringer/06 - Ghostwriter.flac
    
/mnt/nfs/Music/RJD2/2002 - Deadringer/10 - Chicken-Bone Circuit.flac
    
/mnt/nfs/Music/FC Kahuna/2003 - Hayling/01 - Hayling _Original_.flac
    
/mnt/nfs/Music/Lamb/2003 - Between Darkness and Wonder/04 - Angelica.flac

    I’m trying to loop through it like so :

    while read -r line; do
    
 wavfile=$(basename "$line")
    
 wavfile="${wavfile%.*}"
    
 ffmpeg -i "$line" "$2/$wavfile.wav"
    
done <$1

    ...where $1 is where I would pass the name of the text file and $2 is the destination directory.

    Here is the output with the irrelevant ffmpeg junk pruned out :

    Input #0, flac, from '/mnt/nfs/Music/Rob D/1995 - Clubbed To Death/Rob D - 02 - Clubbed To Death _Kurayamino Variation_.flac':

    If you pay attention to the paths that ffmpeg reports don’t exist, you’ll see that a seemingly random number of characters has been removed from the beginning. This appears to happen on even numbered lines, but odd numbered lines work. I can only reproduce this behavior when using ffmpeg. If I replace the ffmpeg line with a simple echo statement, every file path is shown to be correct. How can this be ?

    Other suggestions of accomplishing this are also welcome, however I do need the files processed in the order by which I have them listed in the file.

  • Python and FFmpeg Automation Giving Error

    22 mars 2020, par Tech

    I have a list of videos in a folder. I want to use ffmpeg for all of them at once. But my script is giving an error. I couldn’t find why.

    My video list like these :

    713 - The.Devils.Advocate.1997.1080p.BluRay.x264.mp4’
    714 -The.Terminal.2004.1080p.BluRay.x264.mp4’
    363-The.King’s.Speech.2010.1080p.BluRay.x264-.mp4"

    My code is here :

    import os
    

    
path = './'
    

    
for filename in os.listdir(path):
    
    if (filename.endswith(".mp4")): #or .avi, .mpeg, whatever.
    
        folder_name = str(filename)[0:3]
    
        try:
    
            os.mkdir(folder_name)
    

    
        os.system("ffmpeg -i " + filename + " -codec: copy -start_number 0 -hls_time 10 -hls_list_size 0 -f hls " + folder_name + "/HD.m3u8")
    
    else:
    
        continue

    And I’m getting this error :

      File "hlsyarat.py", line 12
    
    os.system("ffmpeg -i " + filename + " -codec: copy -start_number 0 -hls_time 10 -hls_list_size 0 -f hls " + folder_name + "/HD.m3u8")
    
     ^

  • FFMpeg concatenation with large list of inputs — how to minimize command line length

    27 août 2020, par huitlacoche

    I have a python tool that concatentates several mp4s together into a single movie file using FFMPEG run from a subprocess call. The issue is that an arbitrarily large number of inputs in the command string will hit the windows CLI character max.

    


    ffmpeg -y -i a.mp4 -i b.mp4 -i c.mp4 -f lavfi -t 0.1 -i anullsrc  -filter_complex '[0]scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:(ow-iw)/2: (oh- ih)/2,setsar=1[0:v];[1]scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:(owiw)/2:(oh-ih)/2,setsar=1[1:v];[2]scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:(ow- iw)/2:(oh-ih)/2,setsar=1[2:v]; [0:v][3:a][1:v][3:a][2:v][3:a]concat=n=3:v=1:a=1[v][a]' -c:v libx264 -map [v] -map [a] output.mp4

    


    Assuming 3 input movies that may or may have audio (hence the null audio source).
This works fine assuming there are no more than 30-50 input files. Often the input files have rather long filepaths and can get long very quickly.

    


    After doing a bit of reading I tried a simple :

    


    ffmpeg -f concat -i files.txt -c copy output.mp4

    


    Which works if I can guarantee that all the files are the same codec/resolution/etc, but this cannot be guaranteed.
I'm not clear on how to translate my filter_complex to work with a text file of inputs. Finding a specific enough solution has proven elusive.

    


    I'd be perfectly fine assigning the input paths to a temporary environment variable but in my use case this doesn't seem to work either. The subprocess call doesn't seem to translate wildcard %MYVAR% calls to environment variables.

    


    I feel like there has to be an answer to this problem. If anyone can suggest a solution I would greatly appreciate it.

    


    Thanks !
