• FFMPEG "Segmentation fault" with network stream source

  23 décembre 2023, par user11186466

  I use release : 4.2.2 (static) from "https://johnvansickle.com/ffmpeg/"

  



  Final code will be on "Amazon AWS lambda"

  



  Goal : use a url stream and add watermak

  



  Link to video : ​https://feoval.fr/519.mp4

  



  Link to Watermak : ​https://feoval.fr/watermark.png

  



  ./ffmpeg -i "https://feoval.fr/519.mp4" -i "./watermark.png" -filter_complex "overlay=W-w-10:H-h-10:format=rgb" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4


  



  return "Segmentation fault"

  



  I have the same error on my computer and on AWS Lambda server

  



  ./ffmpeg -i "https://feoval.fr/519.mp4" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4


  



  work (but not watermak)

  



  ./ffmpeg -i "./519.mp4" -i "./watermark.png" -filter_complex "overlay=W-w-10:H-h-10:format=rgb" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4


  



  work (but not with stream)

  



  Thanks you very much !

• 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 :

  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
