• FFMPEG "Segmentation fault" with stream source and watermark

  4 mars 2020, par Magikey

  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

• "Pixel format 'yuvj420p' is not supported" when converting image to video using CUDA hardware acceleration

  11 février 2020, par laurent

  I’m trying to convert an image to a video using CUDA hardware acceleration but I can’t get it to work.

  The basic command I have is this one :

  ffmpeg -y -hwaccel cuvid -i tests/MediaSamples/portrait_0.jpg -t 10 out.mp4

  And I’m getting this error :

  [AVHWFramesContext @ 0x32d3f00] Pixel format 'yuvj420p' is not supported
  
  [mjpeg @ 0x2d18480] Error initializing a CUDA frame pool
  
  cuvid hwaccel requested for input stream #0:0, but cannot be initialized.
  
  Error while decoding stream #0:0: Invalid argument

  I’ve tried setting the pixel format like so, but that didn’t help :

  ffmpeg -y -hwaccel cuvid -pix_fmt yuv420p -i tests/MediaSamples/portrait_0.jpg -t 10 out.mp4

  I’ve also tried many other flags but can’t get anything to work. Any idea what the issue might be ?
