• Crontab starts again befor the process of conversion in ffmpeg ends(depending on time supose /2 minutes) How to Control that ?

  18 décembre 2016, par A Sahra

  I am running a bash .sh file every two minutes with crontab. the problem is that when crontab runs bash file the process of ffmpeg video conversion starts,the conversion time varies depending on length of videos, i have set the crontab to run every two minutes. crontab runs again after two minutes before end of ffmpeg conversion.

  How to Figure out :

  control of crontab and conversion process so the crontab doesn’t starts again until process of conversion is not completed.

  #!/bin/bash
  
  # set PATH to check existance of video file in this directory
  
  checkfiles=/home/webuser/public_html/shareportal/convert_Up_videos/*
  
  checkforfiles=/home/webuser/public_html/shareportal/convert_Up_videos
  
  movetodire=/home/webuser/public_html/shareportal/uploaded_videos/
  
  conversionprocessdir=/home/webuser/public_html/shareportal/conversion_process/

  blockpath=/home/webuser/public_html/shareportal/block.txt
  
  processid=/home/webuser/public_html/shareportal/processid.txt
  
  #format of output video file
  
  webm='webm'
  
  if [ "$(ls -A $checkforfiles)" ]
  
  then 
  
  #check directory for files to convert
  
  for f in $checkfiles
  
      do  
  
          fullfilename="$f"
  
          filename=$(basename "$f")
  
          filewithoutextforimage="${filename%.*}"
  
          nametofile=$filewithoutextforimage | cut -c1-10;
  
          echo $filewithoutextforimage | cut -c1-10 1> $blockpath 2>&1
  
      filewithoutext="${f%.*}"
  
      fileextention="${f##*.}"
  
      image_path='/home/webuser/public_html/shareportal/video_images/'$filewithoutextforimage'.png'
  
      outputfilename=$conversionprocessdir"$filewithoutextforimage.webm"
  
      #ffmpeg conversion process starts here
  
      if (ffmpeg -i "$f" "$outputfilename" 1>> $blockpath 2>&1) 
  
      then 
  
          #Extract Image of video file on provided time stamp
  
          if (ffmpeg -ss 00:00:06 -i "$f" -vframes:v 1 "$image_path") 
  
          then
  
              echo "Image Extracted"
  
          else
  
              echo "Could not Extract Image"
  
          fi
  
          echo "Video Converted";
  
      else
  
          echo "Could Not Convert Video"
  
      fi
  
      #conversion Ends!!
  
      mv "$outputfilename" $movetodire
  
      mv "$fullfilename" $movetoArchive
  
  done

• Improve hls VOD mode hls performance problem.

  19 août 2018, par Ronak Patel

  Improve hls VOD mode hls performance problem.
  This fixes the creation of the hls manifest in hlsenc.c by writing the
  
  entire manifest at the end for VOD playlists. Live & Event Playlists are unaffected.
  
  This also fixes the behavior with HLS_TEMP_FILE to work correctly when
  
   hlsflags temp_file is specified, instead of always relying on use_rename, which caused these problems.
  Files that would previously take over a week to fragment now take
  
  1 minute on the same hardware. This was a 153 hour audio file (2.2GB of audio).
