• FFmpeg metadata tags for YouTube 3D side-by-side movies

  17 février 2021, par Some1Else

  YouTube requires specific metadata tags for 3D Side-By-Side format movies. If the tag is not there then YouTube does not give the anaglyph playback options for the end user.

  



  Their "help" is here
https://support.google.com/youtube/answer/7278886?hl=en-GB

  



  I am trying to get FFmpeg to add the MP4 tag when building my movie.

  



  Code that works now for a series of PNG files into a MP4.

  



  "ffmpeg.exe" -framerate 60 -i "VID%05d.PNG" -c:v libx264 -preset:v veryslow -profile:v high -crf 15 -s 1280x720 -pix_fmt yuvj420p -an -y "OUTPUT.MP4"


  



  But when I add the tag from the YouTube help page

  



  "ffmpeg.exe" -framerate 60 -i "VID%05d.PNG" -c:v libx264 -preset:v veryslow -profile:v high -crf 15 -s 1280x720 -pix_fmt yuvj420p -an -y -x264opts "frame-packing=3:frame-packing-interpret=1:frame-packing-quincunx=0:frame-packing-grid=0,0,0,0" "OUTPUT.MP4"


  



  I get this error from FFmpeg

  



  [libx264 @ 0000000002a8c3a0] bad option 'frame-packing-interpret': '1'


  



  This page (ignore the proselytising)

  



  http://www.pantherdynamics.yolasite.com/panther-dynamics-blog/uploading-3dsbs-content-to-youtube

  



  says you only need to use this tag

  



  -x264opts frame-packing=3


  



  Using that does make FFmpeg finish correctly, but the SBS is still ignored by YouTube

  



  The YouTube engineer blog post here

  



  https://youtube-eng.googleblog.com/2011/09/getting-3d-content-on-youtube_8.html

  



  links to an older supposed 3D movie that also does not give 3D options any more.

  So maybe even YouTube's own 3D movies are crippled ?

  



  What am I doing wrong ? Any FFmpeg gurus able to help ?

  


• Use FFMPEG to restream RTMP source to YouTube - no video stream in output

  5 février 2018, par Mike Miller

  I am attempting to grab the .m3u8 file from an nginx-rtmp server and pass it along to YouTube rtmp. I believe this to be possible (for example here : https://stackoverflow.com/a/11978820/1552594 although this is on the same host). The command I am using is :

  ffmpeg -analyzeduration 0 -i \
  
  http://source.rtmp.server/hls/stream.m3u8 -pix_fmt yuv420p \ 
  
  -f flv rtmp://a.rtmp.youtube.com/live2/xxxx-xxxx-xxxx-xxxx

  However the output contains only audio and YouTube doesn’t like it. The command produces following :

  

  As you can see no Video stream in output metadata, stream mapping shows only audio and the trace shows 0kb of Video for 651kb of Audio

  Any help much appreciated

  MORE INFO

  Improved version of the command lifted from this article :

  https://judge2020.com/restreaming-a-m3u8-hls-stream-to-youtube-using-ffmpeg/

  "Restreaming a m3u8 HLS stream to Youtube using FFMPEG" AKA exactly what I am trying to do.

  The command I am sending is now :

  ffmpeg -re -i "http://source.rtmp.server/hls/stream.m3u8" \ 
  
  -strict -2 -c:v copy -c:a aac -ar 44100 -ab 128k -ac 2 -flags \ 
  
  +global_header -bsf:a aac_adtstoasc -bufsize 3000k -f flv \ 
  
  "rtmp://a.rtmp.youtube.com/live2/xxx-xxxx-xxxx-xxxx"

  I got pretty much exactly the same response except with the Audio being read and output using aac codec.

  

  MORE MORE INFO

  I have found that adding a mapping can force the video stream into the output :

  ffmpeg -re -i "http://source.rtmp.server/hls/stream.m3u8" \
  
  -strict -2 -c:v copy -c:a -map 0:0 -map 0:1 -ar 44100 -ab 128k -ac 2 \ 
  
  -flags +global_header -bsf:a aac_adtstoasc -bufsize 1000k \
  
  -f flv "rtmp://a.rtmp.youtube.com/live2/xxxx-xxxx-xxxx-xxxx"

  This throws up the error that has presumably been resulting in the video stream being silently dropped :
