• Use ffmpeg Windows batch script on OS X

  3 novembre 2015, par andisk

  I got an ffmpeg batch script written by someone. The script takes all video clips of a specific folder, cuts off first and last frame, converts the clips to ProRes and saves them in a new folder. I got it running under Windows (just have to double-click the *.bat file and it does what it’s supposed to do).
  But now I need that same script running on a mac. I’ve installed ffmpeg over homebrew. Then I tried to make a Automator-Service, but with no success. Best thing would be if I could just right click on the folder with the videos, go to services and click on convert. I’m not really into coding and scripting, but the people who should use the script are happy when they find the power switch of the computer..
  Can anyone help me with this ?
  Cheers andisk

  Edit : Here’s the code

      `@echo off
  
  
  
  
  
      mkdir tmp
  
      mkdir converted
  
  
  
  
  
      set pathtofind=%~dp0
  
      echo Searching for files in %pathtofind%%1\
  
  
  
  
  
      setlocal enableextensions
  
      setlocal ENABLEDELAYEDEXPANSION
  
  
  
  
  
  
  
      for %%f in (%pathtofind%%1\*) do (
  
              echo Handling file %%f
  
              ffmpeg -y -loglevel quiet -i %%f tmp\%%d.png
  
              set count=0
  
              for %%x in (tmp\*) do set /a count +=1
  
              echo Deleting frames 1 and !count!
  
              del tmp\1.png
  
              del tmp\!count!.png
  
              echo Saving %%~nf.mov
  
              ffmpeg -y -loglevel verbose -f image2 -r 24 -i tmp\%%d.png -vcodec prores -profile:v 1 -r 24 converted\%%~nf.mov
  
              del /q tmp\*.*
  
  
  
              echo ---------------------------
  
      )
  
  
  
  
  
      rd tmp`

• Time issues in ffmpeg script (MP4 to MP3 conversion)

  16 février 2018, par Alex

  I use the code below as script on my Debian PC to create MP3 files from MP4 video files for adding to podcast app on android phone.

  But each time I click pause/forward time position (not indication) is set up in random way after resuming. Please help improve the code below to solve this problem.

  for f in *.mp4; do
  
    ffmpeg -i "$f" -map 0:a -codec:a libmp3lame -b:a 96k "${f%.mp4}.mp3"
  
  done
  
  for f in *.mp3; do
  
    vbrfix -always -makevbr -lameinfo "$f" "${f%.mp3}.mp3"
  
    rm -rf vbrfix.log vbrfix.tmp
  
  done

• PHP thumbnail list for video files in directory / playback on click (VLC)

  10 mai 2017, par MikeSkril

  Basically I’m looking for a very simple media server.

  I have a server running on a local machine (Ubuntu). There are video files in var/www/movies which I want to index within a web browser.

  I need to show a thumbnail for each file (ffmpeg ?) and a click on the thumbnail would open/play the video file with VLC.

  Anybody knows of an existing script that I could build on, or would I have to start from scratch ?
