• 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 !

• ffmpeg slideshow not working

  4 février 2013, par Benjen

  I am trying to create a simple slideshow video based on two images ('ocean001.jpg' and 'ocean002.jpg'). I am using the command as listed in the ffmpeg documentation, but i always end up with a blank (e.g. black) video file 15 seconds in duration.

  I have checked to confirm that the two image files are the same size. Both are 1024x768px.There are also no errors reported.

  Can anyone tell me what I am doing wrong ?

  Here is the output of the command I am using :

  ffmpeg -f image2 -r 1/15 -i ocean%03d.jpg -vcodec libx264 out.mp4

  Below is the output of the above command :

• ffmpeg says "No JPEG data found in image" when reading image paths from Linux pipe

  18 septembre 2021, par user16945608

  I'm trying to convert a set of pictures into a video, and I want to read the file paths of the pictures from the pipe. The command I would like to run looks like this :

  


  find dir/*.JPG | sort | ffmpeg -f image2pipe -r 1 -vcodec mjpeg -s 6000x4000 -pix_fmt yuvj422p -i - -vcodec libx264 -s 1080x720 -r 20 -pix_fmt yuv420p out.mkv

  


  But I keep obtaining the No JPEG data found in image error. Here is the full log :

  The pictures are in the following format (with mediainfo) and the filenames are in the form DSC_1234.JPG :

  


  Format                                   : JPEG
Video
Format                                   : JPEG

Height                                   : 4 000 pixels

Color space                              : YUV
Chroma subsampling                       : 4:2:2
Bit depth                                : 8 bits
Compression mode                         : Lossy


  


  Also, I would like to avoid using a solution without piping the paths (with -f image2 -i DSC_%04d.JPG for example). Do you have any idea what's happening ?
