• Download hls m3u8 stream with ffmpeg comes only with video - no audio

  20 avril 2022, par Arthur Meier

  I want to download a hls m3u8 stream from an internet source. I was able to get the video as mp4-file. But there is no audio. I've tried already serveral ffmpeg instructions in the windows terminal but with no success. I've change from power shell to cmd and use some of this

  


  ffmpeg -i https://dms.redbull.tv/v4/dms/media/stv/AAEJ0EHC58GGJY1D7GWS/640x360@971824/personal_computer/chrome/at/playlist.m3u8 -c:v copy -c:a copy -t 30 -bsf:a aac_adtstoasc output.mp4

  


  or

  


  ffmpeg.exe -i "https://dms.redbull.tv/v4/dms/media/stv/AAEJ0EHC58GGJY1D7GWS/640x360@971824/personal_computer/chrome/at/playlist.m3u8" -map -codec:a libmp3lame -b:a 96k -bsf:a aac_adtstoasc -c copy output.mp4

  


  The m3u8 addresses I've got using the browser tools for developers from firefox by searching in the network analysis.

  


  I also tried to get the video converted and saved with vlc - but also had no success. For the profile, I tried "Video - H.264 + MP3 (MP4)" with the setting "Keep original audio track". But also with other choices, I have had no success.

  


  I hope someone here has a working solution :-))

  


• Displaying ffmpeg conversion progress

  29 mars 2014, par Hiigaran

  I'm trying to get an admin function made, in which I want to show a basic status of any file conversion(s) that may or may not be happening upon page load. I'm not entirely sure how to proceed with this, so here is what I have at the moment :

  exec("ffprobe -v quiet -print_format json -show_format '".$fileNameIn.".".$ext."' > /var/www/resources/ffmpegFormat.log");
  
  exec("/ffmpeg/ffmpeg -loglevel 'verbose' -i '".$fileNameIn.".".$ext."' '".$fileNameOut.".flac' null >/dev/null 2>/var/www/resources/ffmpeg.log &",$ffmpegOutput);

  My idea is to use ffprobe to output some information about the file to be converted, then use PHP in some way to read the output file (ffmpegFormat.log) for the total file duration. Once read, ffmpeg begins, while outputting to its own file (ffmpeg.log).

  I'm not looking for anything fancy, like live updates on the progress, so I'm content with simply having a script read the current duration from the last line of the ffmpeg.log file, compare it to the total duration from the ffmpegFormat.log file, and display a percentage only after a page load/refresh.

  I've placed a restriction on conversion to only one file at a time, for the sake of simplifying this progress indicator (and due to a lack of processing power on this computer).

  Assuming there's no simpler way than my idea, how can I do this ?

• 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 ---------------------------
  
      )
