Concatenating on Windows throws "Invalid data found when processing input" while it works on Mac and Linux
15 février 2020, par miguelmorinI 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.MOVI 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 ffmpeg version git-2020-02-11-f15007a Copyright (c) 2000-2020 the FFmpeg developers built with gcc 9.2.1 (GCC) 20200122 configuration : —enable-gpl —enable-version3 —enable-sdl2 —enable-fontconfig —enable-gnutls —enable-iconv —enable-libass —enable-libdav1d —enable-libbluray —enable-libfreetype —enable-libmp3lame —enable-libopencore-amrnb —enable-libopencore-amrwb —enable-libopenjpeg —enable-libopus —enable-libshine —enable-libsnappy —enable-libsoxr —enable-libtheora —enable-libtwolame —enable-libvpx —enable-libwavpack —enable-libwebp —enable-libx264 —enable-libx265 —enable-libxml2 —enable-libzimg —enable-lzma —enable-zlib —enable-gmp —enable-libvidstab —enable-libvorbis —enable-libvo-amrwbenc —enable-libmysofa —enable-libspeex —enable-libxvid —enable-libaom —enable-libmfx —enable-ffnvcodec —enable-cuvid —enable-d3d11va —enable-nvenc —enable-nvdec —enable-dxva2 —enable-avisynth —enable-libopenmpt —enable-amf libavutil 56. 39.100 / 56. 39.100 libavcodec 58. 68.102 / 58. 68.102 libavformat 58. 38.100 / 58. 38.100 libavdevice 58. 9.103 / 58. 9.103 libavfilter 7. 75.100 / 7. 75.100 libswscale 5. 6.100 / 5. 6.100 libswresample 3. 6.100 / 3. 6.100 libpostproc 55. 6.100 / 55. 6.100 Splitting the commandline.

Update because of wrong command
I had mistyped the command. The right command has a
