• Install ffmpeg on elastic beanstalk using ebextensions config

  18 mai 2017, par user3581244

  I’m attempting to install an up to date version of ffmpeg on an elastic beanstalk instance on amazon servers. I’ve created my config file and added these container_commands :

      container_commands:
  
          01-ffmpeg:
  
              command: wget -O/usr/local/bin/ffmpeg http://ffmpeg.gusari.org/static/64bit/ffmpeg.static.64bit.2014-03-05.tar.gz
  
              leader_only: false
  
          02-ffmpeg:
  
              command: tar -xzf /usr/local/bin/ffmpeg
  
              leader_only: false
  
          03-ffmpeg:
  
              command: ln -s /usr/local/bin/ffmpeg /usr/bin/ffmpeg
  
              leader_only: false

  Command 01 and 03 seems to work perfectly but 02 doesn’t seem to work so ffmpeg doesn’t unzip. Any ideas what the issue might be ?

  Thanks,
  Helen

• Removing file in windows batch script not working

  13 février 2020, par BluePrint

  I’m trying to create a batch script for trimming 25 seconds from the beginning of all mp4 files in a folder. The batch script is located in the same folder as the files, and there is a folder called trimmed in the same folder. This is my script so far :

  @echo off
  
  setlocal DisableDelayedExpansion
  
  
  
  :promptdel
  
  set /p delorig=Delete original file (default no)? [Y/N]: 
  
  
  
  if not defined delorig (
  
    set delorig=N
  
  )
  
  
  
  set "vartwo="&for /f "delims=YNyn" %%i in ("%delorig%") do set vartwo=%%i
  
  
  
  if defined vartwo (
  
    echo Please state Y or N!
  
    goto :promptdel
  
  )
  
  
  
  for %%a in ("*.mp4") do (
  
    echo Starting %%a
  
  
  
    rem "Need to rename since file names may contain whitespaces"
  
    ren "%%a" "working.mp4"
  
    ffmpeg -loglevel panic -hide_banner -i "working.mp4" -ss 00:00:25.000 -c:v copy -c:a copy "trimmed\%%a"
  
    ren "working.mp4" "%%a"
  
  
  
    echo %delorig%
  
    if %delorig% == "Y" (del "%%a" /f /q)
  
    if %delorig% == "y" (del "%%a" /f /q)
  
  
  
    echo %%a finished!
  
  )
  
  
  
  pause

  My problem is that the original file does not get removed regardless of if I input y/Y or n/N. What am I doing wrong ?

• FFMPEG : How to merge two sounds with good quality ?

  26 avril 2021, par Mahmoud Eidarous

  I'm trying to merge a recorded sound with an audio file and make it sound like an original song.

  


  I'm using this command

  


  ffmpeg -i audiofile.mp3 -i recorded_file.wav -filter_complex "[0:a]aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=0.5[a1]; [1:a]aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=7[a2]; [a1][a2]amerge=inputs=2,pan=stereo|c0code>

  


  This command does achieve the merge, but the quality of the output song is very bad.

  


  I tried to manipulate the volume values but still the quality is bad.

  


  I believe a filter is required on the recorded sound or something...

  


  Any help to make the output sound like an original song would be really appreciated.
