• Web page with script

  28 April 2017, by Peter

  please be patient with me, I have never been very much into the coding (only at the university just a little) but here is one thing I would love to have. I havent done any research before asking before I dont even know what to search for :) but here is what I would like to do:

  I have synology device with multicast TV stream connected to it. I have installed ffmpeg and everytime I want to record a TV show I have to do it from CLI so I was thinking it would be nice to run this ffmpeg from the web page. I mean I would click the TV channel from the drop down menu, set the name of a file, set the time and click RUN and then the command (ffmpeg -i http://MULTICAST_STREAM-variable -acodec copy -vcodec copy /var/services/homes/xxx/NAME_OF_TV_SHOW.mpg) will execute on my synology...Is something like this possible? (I hope it is)...What exactly should I search for?

  Thank you very much

• Batch-file script to automatically add an mp3 track to the same mp4 video in ffmpeg [closed]

  15 January, by Poro

  I have several video and audio files:

  


  

  • file 01.mp3

  


  • file 01.mkv

  


  • file 02.mp3

  


  • file 02.mkv

  


  • file 03.mp3

  


  • file 03.mkv

  


  


  what should be the script for ffmpeg to take each video file and add an additional second audio track with the same name (file 01.mkv + file 01.mp3)?

  


  it's a main question

  


  But ultimately I need to get each video (let's say it's mp4) with 3 audio streams:

  


  

  1. mixed stream from mp3 (100%) + mkv (10% volume) - by default

  


  2. stream from mp3 file (100%)

  


  3. and last stream from mkv (100% volume)

  


  


  I would like to write all these commands in one batch-file

  


  I already use .bat files to automatically convert to another format (for example):

  


  for %%i in (*.mkv) do (
ffmpeg -y -i "%%i" -c copy "%%~ni.mp4"
)


  


  As far as I understand, for the audio track task I need to set a variable for .mp3 (besides %%i ) and make it compare to the .mkv name, but I don't understand how to do it correctly.

  


  to manually add a track, I use (for example):

  


  ffmpeg -i video.mkv -i audio.mp3 -map 0 -map 1:a -c:v copy -shortest output.mkv


  


  to change the track order and set the default track, I use (for example):

  


  ffmpeg -i input.mkv -map 0:v:0
-map 0:a:2 -map 0:a:0 -map 0:a:1 -map 0:a:3
-map 0:s -c copy
-disposition:a:0 default
reordered.mp4


  


  It takes a lot of time to do all this work with a lot of files. it would be great to delegate it to a machine.

  


• need script to delete after convert, ffmpeg

  6 February 2017, by Gsharks

  I’m a virgin to this whole CMD scene. I can really use some help.
  I just want to delete the file after it converts.
  Heres what I have so far:
  update: I figured how to delete after conversion, but its after everything is converted, I want to delete the file RIGHT AFTER EACH CONVERT...

  dir/b/s *.mkv >mkvlist.txt
  
  for /F "delims=;" %%F in (mkvlist.txt) do ffmpeg.exe  -i "%%F" -vcodec copy -acodec copy "%%~dF%%~pF%%~nF.mp4"
  
  del mkvlist.txt del *.mkv
