• Ffmpeg converted videos (longer than 30s) not playing in chrome

  3 février 2016, par Razvan Ilin

  As the title says, I’m having issues with converted videos that are over 30s. They are not playing in chrome but they do work in all other browsers. The thing is, if the video is less than 30s than it plays fine in chrome too.

  The input file is mpeg4 encoded and I’m trying to convert it using the h264 codec. The conversion is done on a linux server with the help of a drupal module which converts the video on upload automatically.

  This is the command and output :

  /opt/ffmpeg/ffmpeg -i '/var/www/html/website/videos/original/2016-02-02-16-52-44-758_1.mp4' -strict experimental -vcodec 'libx264' -pix_fmt 'yuv420p' -vprofile 'baseline' -an -pass '1' -passlogfile '/tmp/1454496233-56b1d9e99deb8-multipass'  -y /tmp/1454496233-56b1d9e99dd6f.mp4

  I also tried with the latest version of ffmpeg but I have the same problem.
  Does anyone have any ideas on why this is happening ?

  Note that this is a log from doing a two-pass encoding (it was the only way to get a log from drupal). The two-pass encoding works if I specify a bitrate in the ffmpeg command, but as I said, it doesn’t work on chrome but works on all other browsers.

• ffmpeg image sequence from text file not rendering correctly

  4 juillet 2018, par Rich

  I’ve been working with ffmpeg and I have got it to work perfectly quite a few times, but as of recent I am running into an issue where all the images from my text file arent used.

  My text file looks like -

  ffconcat version 1.0
  
  file 'gallery-house-77-west-55th-street-01.jpg'
  
  duration 4.44
  
  file 'img03.jpg'
  
  duration 4.44
  
  file 'inside.png'
  
  duration 4.44
  
  file 'placeholder.png'

  (amount of files, file names and extensions will always vary)

  And I’ve tried several combinations but as of now my ffmpeg function looks like —

  ffmpeg -i audio.mp3 -safe 0 -f concat -i paths.txt -c:a copy -c:v libx264 \
  
  -vf "scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:(ow-iw)/2:(oh-ih)/2,fps=25,format=yuv420p" -vsync vfr -movflags +faststart -y output.mp4 2>&1');

  When trying to run it, the video seems to convert but has various weird behaviors - sometimes only the middle file(image) in the list is shown or the first 2 only are shown/rendered.

  The audio is playing correctly though.

  I’ve tried setting the framerate for the input and I also tried setting it for the output but it leads to more strange behavior.

  This is what is echoed when running my above ffmpeg command -

  Any ideas whats causing the image sequence to fail ?

  EDIT

  After some more debugging I think it may be related to the fact that all the files dont have the same extension. How can I make it so that it doesn’t have to be that way or is that already a default setting and the issue is else where ?

• Frame rate very high for a muxer not efficiently supporting it

  23 avril 2014, par DevDave

  I got an error when trying to run the following command with FFMpeg :
