• Use ffmpeg to edit metadata titles for multiple files

  19 mars 2017, par Nicholas Wireman

  I’d like to be able to add/edit video metadata titles to multiple files at once or with a single command, but I don’t know how to tell ffmpeg to do this.

  I read a similar post on the Ubuntu Forums, but I have never used string manipulation in Linux before, so the commands I’m seeing in the post are way out of my comprehension at the moment, and much of the discussion goes over my head.

  I’ve got all of my video files in a filename format that includes the show name, the episode number, and episode title. For example :

  show_name - episode_number - episode_title.extension

  Bleach - 001 - A Shinigami Is Born !.avi

  Is there a simple way to read the title and episode number from the filename and put it into a metadata tag without having to go through each and every file manually ?

  EDIT 1 : So I found out that I can iterate through files in a directory, and echo the filename, and I was told by a friend to try bash to parse the strings and return values from that to use in the ffmpeg command line. The problem is, I have absolutely no idea how to do this. The string manipulation in bash is very confusing on first look, and I can’t seem to get it to output what I want into my variables. My test bash :

   for file in "Bleach - 206 - The Past Chapter Begins! The Truth from 110 Years Ago.mkv"; do   extension=${file##*.} showName=${file%% *} episode=${file:9:3}; echo Extension: $extension Show: $showName Episode: $episode;    done

  That outputs

  Extension : mkv Show : Bleach Episode : 206

  Which are all the variables I’m going to need, I just don’t know how to move those to be run in ffmpeg now.

  EDIT 2 : I believe I was able, through much trial and error, to find a bash command that would do exactly what I wanted.

  for file in *; do   newname=${file:0:-4}_2 ext=${file##*.} filename=${file} showname=${file%% *} episode=${file:9:3} nameext=${file##*- } title=${nameext%.*};     ffmpeg -i "$filename" -metadata title="$title" -metadata track=$episode -metadata album=$showname -c copy "$newname.$ext";    mv -f "$newname.$ext" "$filename";    done

  This lets me parse the information from the filename, copy it to some variables, and then run ffmpeg using those variables. It outputs to a second file, then moves that file to the original location, overwriting the original. One could remove that section out if you’re not sure about how it’s going to parse your files, but I’m glad I was able to get a solution that works for me.

  7 décembre 2016, par denis -

  Je profite de #3148 pour revenir sur une demande qui doit sans doute être assez spécifique.

  On utilise beaucoup les dans les rubriques et on aimerait avoir la possibilité d’avoir par défaut les bonnes urls selon la traduction

  Pour ceci 05. Réveillon

  On a par défaut uniquement l’url /reveillon

  Ce qui serait évidemment bien c’est de pouvoir avoir les 3 et donc une arborescence de ce type.

  mmaldec : correct package buffering accounting
  The assert in ffmmal_stop_decoder() could trigger sometimes. The
  
  packets_buffered counter was indeed not correctly maintained, and
  
  packets were not subtracted from it if they were still in the waiting
  
  queue.
  For some reason, this happened especially with VC-1.
