• Writing metadata (Artist Name, Song Title, Year, Album, Duration, Genre) to mp3/m4a audio file using youtube-dl (subsequent AtomicParsely error)

  10 décembre 2016, par IRNotSmart

  I am extracting audio only from youtube videos using youtube-dl. I would like to write the metadata (i.e. Artist Name and Song Title, Year, Album, Duration, Genre) into the mp3/m4a file after downloading. My attempt to accomplish this starts with this code :

  @echo off
  
  youtube-dl --format m4a/mp3 --youtube-skip-dash-manifest --embed-thumbnail -o "%%(title)s.%%(ext)s" --metadata-from-title "%%(artist)s - %%(title)s" --add-metadata 2Y6Nne8RvaA
  
  pause

  This code produces the following output :

  Press any key to continue . . .

  As you can see, I am able to successfully able to add a few of the tags from the video, but not all of them and the Year is royally screwed up.
  

  What is this AtomicParsely error and how do I remedy it ? Do I need this program to correctly add all the Metadata to the file that I want, or can this be accomplished in another way ?

  Referencing Steven Penny’s post, FFmpeg metadata not showing in Windows ?, is solving this problem as simple as using an ffmpeg command ?

  When I do a google search for this song, the first link that shows is the exact link I’m using on YouTube, and the search shows pertinent metadata (see below). I’m not sure if this data is input manually by users, or if Google mined this from the video :
  

  I admit that I’m new to using youtube-dl and ffmpeg, but with the help of the commenters on StackOverflow, I’m learning more each day. This post is a follow-up to my previous question : Downloading YouTube to mp3 and writing metadata (artist/song title) to mp3 file using youtube-dl

• ffmpeg : Set "year" metadata equal to first 4 characters of another metadata variable (flac)

  10 février 2020, par Hello

  The flac files I am dealing with has an attributed named "Date released", whose value is in the format "YYYY-MM-DD".

  Is it possible for me to take the "YYYY" from this and set the year variable equal to it ?

      ffmpeg -i input.flac -metadata year= ??? -codec copy output.flac

  Bonus question, is it possible to do this in place without creating a new file ? Or would I have to create a new file and then delete the old one ?

• ffmpeg - How to increase performance ?

  7 mai 2017, par Thanh Dao

  I’m trying to speed up and add background to mp4 videos. It taken a lots of time.

  ffmpeg -i input.mp4 -filter_complex "[0:v]setpts=0.91*PTS[i]; [0:a]atempo=1.1000[p]" -map "[i]" -map "[p]" output-1.mp4 2>&1

  Above command take about 30 minutes to do. The size of input file about 30-40MB, is not too large.
  And next, I run below command to add background to video, take about 30 mins (Background’s resolution is 1280x720)

  ffmpeg -i output-1.mp4 -i background.png -filter_complex "overlay=0:0" output.mp4 2>&1

  It make my system very slow, and performance is very bad.
  What can I do to improve ?
