  • Concatenating on Windows throws "Invalid data found when processing input" while it works on Mac and Linux

    15 février 2020, par miguelmorin

    I need to run a command with a nightly build of FFMPEG to report a bug on the concat protocol. I found it difficult to compile from source with libx264 support on Linux, and I want to spare my Mac computer, so I use the nightly build on Windows from Zeranoe.

    I call this command to concatenate the files :

    ffmpeg -safe 0 concat -i files_to_combine -vcodec libx264 show.mp4

    where files_to_combine is :

    file ./short_DSC_0013.MOV
    
file ./short_DSC_0014.MOV
    
file ./short_DSC_0015.MOV
    
file ./short_DSC_0016.MOV
    
file ./short_DSC_0017.MOV
    
file ./short_DSC_0018.MOV
    
file ./short_DSC_0019.MOV

    I call this command from the directory containing the video files and files_to_combine.

    On Windows with a nightly build, I get the error :

    files_to_combine : Invalid data found when processing input

    I changed file ./DSC_0013.MOV to these options, all with the same error :

    file 'short_DSC_0013.MOV'
    
file '.\short_DSC_0013.MOV'
    
file 'F:\short_DSC_0013.MOV'

    How can I debug this error, or what is the syntax for concatenating on Windows with a nightly build ?

    Update with log-level 48

    I ran the same command with -v 48 and got :

    F :\brain squids>C :\Users\migue\Desktop\ffmpeg-20200211-f15007a-win64-static\bin\ffmpeg.exe -v 48 -i files_to_combine -vcodec libx264 show.mp4

    Update because of wrong command

    I had mistyped the command. The right command has a -f in front of concat, which I found because the accepted answer was able to make the command work in a similar environment :

    ffmpeg -safe 0 -f concat -i files_to_combine -vcodec libx264 show.mp4
