• 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 "buffer queue overflow, dropping" with trim and atrim filters

  I tried with other stackoverflow questions but none of them worked. Also I think it is partially because the trim timings are mixed. That is start time can be anywhere between 0-end. When I make it strictly increasing it is working fine.

• Syntax error : "(" unexpected — with !(*.sh) in bash script

  Regards,

  I want to run a sh file :

  #!/bin/bash
  
  for f in !(*.sh); do ffmpeg -i "$f" -vf yadif=0:-1 -threads 0 -c:v libx264 -pix_fmt yuv420p -r 29.97 -b:v 3000k -s 1280x720 -preset:v slow -profile:v Main -level 3.1 -bf 2 -movflags faststart /mnt/media/out-mp4/"${f%.mxf}.mp4"; rm $f; done

  However I get the following error :

  2: task1.sh: Syntax error: "(" unexpected

  If I try directly on the command line it works perfectly.

  the path and permissions are already reviewed

  Any idea what might be happening ?

  Thank you a lot
