• Streaming to YouTube using FFmpeg Problems

  12 septembre 2022, par jason

  I am trying to stream to a live event I have created inside of YouTube. I am trying to stream a already created video. The command I am using is noted below.

  



  The problem I have is that YouTube is showing the Streaming status as good (picture attached) and it seems to be receiving the data. But there is no sound and no picture in the live event. I'm not sure what the issue could be.

  



  ffmpeg -re -y -i input.mp4 -vcodec libx264 -b:v 600k -r 25 -s 640x360 -filter:v yadif -ab 64k -ac 1 -ar 44100 -f flv "rtmp://a.rtmp.youtube.com/live2/KEY"


  



  Image showing YouTube streaming status :

  



  

  



  Console output :

  Edit -

  



  I have now tested the following codes but I still dotn get any picture or sound.. but the health status in youtube still shows good

  



  I ran this command first

  



  ffmpeg -i input.mp4 -vcodec libx264 -preset medium -maxrate 3000k -bufsize 6000k -vf "scale=1280:-1,format=yuv420p" -g 50 -acodec libmp3lame -b:a 128k -ac 2 -ar 44100 file.flv


  



  and then I ran this

  



  ffmpeg -re -i file.flv -codec copy -f flv rtmp://a.rtmp.youtube.com/live2/<key>&#xA;</key>

  



  I still didnt get any picture

  



  I also tried the full command in 1

  



  ffmpeg -re -i input.mp4 -vcodec libx264 -preset veryfast -maxrate 3000k -bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 -ar 44100 -f flv rtmp://a.rtmp.youtube.com/live2/<key>  &#xA;</key>

  



  still no joy

  


• 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 :

  [youtube] 2Y6Nne8RvaA: Downloading webpage
  
  [youtube] 2Y6Nne8RvaA: Extracting video information
  
  [youtube] 2Y6Nne8RvaA: Downloading thumbnail ...

  [ffmpeg] Adding metadata to 'Kungs vs Cookin' on 3 Burners - This Girl.m4a'
  
  ERROR: AtomicParsley was not found. Please install.
  
  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

• Anomalie #3708 (Nouveau) : .select dans menu lateral

  18 février 2016, par Maïeul Rouquette

  Dans SPIP 3.1
  le fichier form.css.html contient la ligne

  .lat .formulaire_spip select  width:auto ;padding:1px 0 ;
  

  ce qui surcharge la propriété width de

  .formulaire_spip select  font-size:1em ;padding : 3px ; width : 100% ; -webkit-box-sizing : border-box ; -moz-box-sizing : border-box ;-ms-box-sizing : border-box ; box-sizing : border-box ;
  

  Conséquent : un select dans la colonne de gauche peut dépasser. Cf par exemple le "presse-papier" de SPIP bible (voir http://contrib.spip.net/SPIP-Bible-5#forum486046).
