• How to download/convert multiple streams to multiple outputs with FFmpeg ?

  16 avril 2016, par Website Newbie

  Let’s say I have 20 different online stream videos (playlist.m3u8) and I want every video to output to their own .avi files. How can I do that in single file, so I don’t have to download and convert every single one separately ?

  I found a -map command online, but didn’t get straight answer to this.

  Will this be a working code ?

  ffmpeg -i 1playlist.m3u8 -vf scale=768:-1 -vcodec libx264 -crf 24 -acodec copy -map 0 1.avi \
  
  -i 2playlist.m3u8 -vf scale=768:-1 -vcodec libx264 -crf 24 -acodec copy -map 1 2.avi \
  
  -i 3playlist.m3u8 -vf scale=768:-1 -vcodec libx264 -crf 24 -acodec copy -map 2 3.avi

• Running ffmpeg with Mac's Automator to remove metadata

  11 février 2019, par sd100

  Hi so I am having problems running ffmpeg on a folder of movie files with Mac’s automator. My goal is to select a folder and right click/select service and automatically the script should run on only movie files (of mp4 type).

  So I have a Automator workflow receives files or folders in finder. Then I have "Selected Finder items" and then run shell script (code below).

  This works but firstly it gives the ffmpeg verbose output in the results window in the mac which I have to press ok. I tried the "-hide_banner -loglevel panic" but the script doesn’t work then.

  Secondly the "Selected finder items" works but I want to only select a folder and automatically the automator script should go in the folder and run the shell script on only mp4 files (movie).

  Is there anyway to set both requirements ? Any advise would be appreciated !

  Code I’ve tried :

  for f in "$@"
  do
  /usr/local/bin/ffmpeg -i "$f" -map_metadata -1 -c:v copy -c:a copy "$f%.mp4"-new.mp4 ;
  done

  Also am trying to move all converted mp4 files to a directory in the current directory with shell code like this :

  for f in *.mp4 ; do ffmpeg -i "$f" -map_metadata -1 -c:v copy -c:a copy "converted/$f" ; done

  This doesn’t work either in automator as I don’t know how to move the ffmpeg output files into another directory via automator.

• Compress videofiles from context menu in Windows 11 using ffmpeg

  11 janvier 2023, par Rayearth

  I'd looking for an easy way to just right click on a folder in Windows and be able to loop through video files and compress them with ffmpeg with prepared command settings.

  


  Been able to prepare the reg file to import but I think I'm missing something important here (working directory reference I think). How should I pass the working dir path inside a command like that for this mechanism to work ?

  


  Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\Shell\Compress_videos]
@="Compress videos"

[HKEY_CLASSES_ROOT\Directory\Shell\Compress_videos\command]
@="cmd /c for \"%E\" in (.mp4, .mkv, .mov, .avi) do forfiles /m *\"%E\" /c \"cmd /c C:\\Windows\\System32\\ffmpeg.exe -hide_banner -y -hwaccel cuda -i @path -c:v hevc_nvenc -b:v 8000k -c:a copy @fname_compressed.mp4\""
