• Cut audio / Video using ffmpeg on the server [on hold]

  8 décembre 2016, par Mohammed Hussein

  I am rebuilding a project that I built with meteor js from scratch using asp.net mvc and c#

  the project is basically used to cut audio and video given the start time and the end time using ffmpeg on the server,

  but I am facing a problem in both projects,

  if during the process of cutting the audio / video file i lost my internet connection the operation doesn’t complete. what i want is that the operation should complete and write the changes to the database and create the new file on the server despite the fact that i am no longer connected .

  is that possible to do or not ?

      If you think configure made a mistake, make sure you are using the latest
  
      version from Git.  If the latest version fails, report the problem to the
  
      ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
  
      Include the log file "config.log" produced by configure as this will help
  
      solving the problem.

• How to write command line argument input redirection within a bash script ?

  3 septembre 2013, par Serg ikS

  I'm putting together a bash script to run movie rendering jobs. ffmpeg expects a multi-line text file as one of the arguments for concatenation filter to join several files into one. Like this :

  ffmpeg -f concat -i mylist.txt -c copy output

  There's also an option to write it all in a single line like so :

  ffmpeg -f concat -i <(printf "file '%s'\n" A.mp4 B.mp4) -c copy Output.mp4

  How do I write the latter for into a bash script, substituting the file names from other variables ? Tryed splitting the variables, but its not the one that works. $A and $B variables contains paths to input files.

  #!/bin/bash
  
  ...
  
  TMP_LIST=$(printf "file '%s'\n" ${A} ${B})
  
  APPEND="${FFMPEG} -f concat -i <<< {${TMP_LIST}} -c copy ${OUTPUT}"
  
  # run the concatenation:
  
  $APPEND
