• unconnected output - FFMPEG

  9 avril 2018, par Hernan Quintero

  Im trying to make my first apple Service.

  I want FFMPEG to extract 5.1 Audio from a video with this command line :

  ffmpeg -i infile \
  
  -filter_complex "channelsplit=channel_layout=5.1[FL][FR][FC][LFE][BL] 
  
  [BR]" \
  
  -map "[FL]" front_left.wav \
  
  -map "[FR]" front_right.wav \
  
  -map "[FC]" front_center.wav \
  
  -map "[LFE]" lfe.wav \
  
  -map "[BL]" back_left.wav \
  
  -map "[BR]" back_right.wav

  It works very good from the Terminal, but when I try to make a Service in Automator I get the following error :

  Filter channelsplit:BR has an unconnected output

  This is the command line for the service :

  on run {input, parameters}
  
  tell application "Terminal"
  
      activate
  
      set filesString to ""
  
      repeat with file_ in input
  
          set filesString to filesString & " " & quoted form of (POSIX path of file_)
  
      end repeat
  
      do script "for f in" & filesString & "; do
  
  /usr/local/bin/ffmpeg -i \"$f\" -filter_complex 
  
  channelsplit=channel_layout=5.1[FL][FR][FC][LFE][BL][BR] 
  
  -map [FL] front_left.wav 
  
  -map [FR] front_right.wav 
  
  -map [FC] front_center.wav 
  
  -map [LFE] lfe.wav 
  
  -map [BL] back_left.wav 
  
  -map [BR] back_right.wav 
  
  done"
  
  end tell
  
  return input
  
  end run

  Could you guys help me to figure out what I’m doing wrong ?

  Thank you very much.

• MPG to MP4 Video Conversion after Azure Media Services Retirement [closed]

  30 juillet 2024, par Yousef

  I'm hosting a C# Blazor Application in Azure App Service and was leveraging Azure Media Services to transcode mpg videos to mp4 in Jobs. However, Azure Media Services was retired last month and the services are going to stop next week so I have to find an alternative.
I have looked at multiple alternatives but couldn't find a simple conversion tool.
In Azure Media Services I was using the following configuration


  


  I can't seem to find the same configuration in the tools I have looked at. I tried Bitmovin but the encoding takes 5 - 10 Minutes (unlike Azure Media Services which takes 2 minutes) and the result of the encoding is a folder with 4 mp4 segments that are not part of the original mpg video.

  


  I tried ffmpeg locally but I can't get it to work in an Azure App Service.

  


  Does anyone have any suggestion of an alternative to Azure Media Service when it comes to Transcoding mpg videos to mp4 in a background task ?

  


• Compiling FFMPEG for android NDK r9d

  17 juillet 2014, par jawad bin zafar

  I am working on a project in which I need to use FFMPEG for video editing. I have a very short time and compiling takes to much time of me. I have search many tutorial on the web and but no one seem to be working. Some have missing configure file some have command which are broken etc.

  My Question is weather it is necessary to compile FFMPEG with you NDK or we can use a precompile library or we can sign a compile library with our NDK signature.

  Any one knows a working step by step guide to compile and use the compile library into your project.

  Thanks
