• Stream two vides in a row over http?

  24 juillet 2014, par Zlatko

  I have two video files (mpg) and I want to stream them back to a client (mobile devices) but as one video : the first one appended to the second one.

  I know I can use ffmpeg to concat them :

  ffmpeg -i "concat:input1.mpg|input2.mpg|input3.mpg" -c copy output.mpg

  What I want is to avoid creating that concatenated file because I have potentially dozens of files to play, and I want to stream them and stop when the user closes the window and not create that one big output chunk.

  For what it’s worth, I plan to stream those with Node.js.

• Roadmap #3582 : Simplifier l’utilsation des documents

  22 février 2016, par b b

  Merci pour le retour, je mentionnais ressource car, amha, il pourrait grandement simplifier l’usage des documents. Ce que je verrais bien comme plan :

  1. intégration de medocs en 3.2 par ex, première phase de simplification, puisque le plugin permet d’utiliser un raccourci unique
  2. intégration de ressource en 3.3 par ex, toujours un raccourci unique, avec les avantages du principe de ressource en bonus

• How to take metadata from .mp3 file and put it to a video as a text using FFmpeg ?

  6 décembre 2020, par Grrzly

  In my previously opened topic :

  


  How to make FFmpeg automatically inject mp3 audio tracks in the single cycled muted video


  


  I've got detailed explanation from @llogan how to broadcast looped short muted video on youtube automatically injecting audio tracks in it without interrupting a translation.

  


  I plan to enhance the flow and the next question I faced with is how to dynamically put an additional text to the broadcast.

  


  Prerequisites :

  


  

  1. youtube broadcast is up and running by ffmpeg

  


  2. short 3 min video is paying in infinity loop

  


  3. audio tracks from playlist are automatically taken by "ffmpeg concat" and injected in the video one by one

  


  


  this is a basic command to start translation :

  


  


  ffmpeg -re -fflags +genpts -stream_loop -1 -i video.mp4 -re -f concat
-i input.txt -map 0:v -map 1:a -c:v libx264 -tune stillimage -vf format=yuv420p -c:a copy -g 20 -b:v 2000k -maxrate 2000k -bufsize
8000k -f flv rtmp ://a.rtmp.youtube.com/live2/my-key

  


  


  Improvements I want to bring

  


  

  1. I plan to store some metadata in audio files (basically it's an artist name and a song name)

  


  2. At the moment a particular song starts playing artist/song name should be taken from metadata and displayed on the video as text during the whole song is playing.

  


  3. When the current song finishes and a new one starts playing the previous artist/song text should be replaced with the new one etc

  


  


  My question is how to properly take metadata and add it to the existing broadcast config using ffmpeg ?
