  The text above is the output infomation in the shell, and I don't know how to get more detailed information.
What does "Error 5" means ?

  


• Delay in video playback. Not able to identify the cause - AWS S3 region / ffmpeg / Videojs

  17 septembre 2016, par Himansu Kisan

  We are not able to identify the cause for random behavior while playing video on our website. (Sorry, cant share a link since the videos are for registered users only)
  The videos sometimes plays instantly and sometimes it takes over 1 minute to start. Not sure what we are doing wrong.

  We are using AWS S3 Oregon region (not the closest to target region, but it is cheaper) to store video files.
  The video files are encoded using ffmpeg. Below is the syntax

  ffmpeg -i input.mts -codec:v libx264 -threads 4 -movflags +faststart -profile:v high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale="trunc(oh*a/2)*2:720" "output.mp4"

  ffmpeg -i input.mts -codec:v libvpx -threads 4 -quality good -cpu-used 5 -b:v 500k -maxrate 500k -bufsize 1000k -qmin 10 -qmax 42 -vf scale="trunc(oh*a/2)*2:720" -codec:a libvorbis -b:a 128k "output.webm"

  On website, we are using Videojs 5.10.8.
  Below is the code snippet

   <video class="video-js vjs-default-skin vjs-big-play-centered" preload="none" controls="controls" poster="abcd.jpg" style="width:100%;height:100%;min-height:360px;" data-setup="{&quot;autoplay&quot;:true}">
  
  <source src="abcd.mp4" type="video/mp4"></source>
  
  <source src="adcd.webm" type="video/webm"></source>
  
  <p class="vjs-no-js">
