• ffmpeg : create .mp4 from .mp3 and .jpg

  28 juin 2021, par user292344

  I've searched for the best way to do this and nothing seems to work. I'm using Ubuntu 20.04.

  This is the command that I'm using :

  


  ffmpeg -y -hide_banner -loop 1 -i test.jpg -i test.mp3 -c:v libx264 -tune stillimage -c:a aac -b:a 192k -pix_fmt yuv420p -shortest out.mp4

  


  The result won't play in VLC. And it takes a very long time for the command to finish. Also the test.jpg image had an odd number y dimension, so I made it even with imagick by reducing that size by 1.

  


  How do you do this 'correctly' ?

  


• avfilter/vidstab : add option for file format specification

  22 octobre 2023, par Gyan Doshi

  avfilter/vidstab : add option for file format specification
  The vidstab library added support in Nov 2020 for writing/reading
  
  the transforms data in binary in addition to ASCII. The library default
  
  was changed to binary format but no changes were made to the AVfilters
  
  resulting in data file for writing or reading being always opened as text.
  
  This effectively broke the filters.
  Option added to vidstabdetect to specify file format and open files in
  
  both filters with the correct attributes.

• TCP Connection refused error when using FFMPEG for audio stream to HTTP on macOS

  26 novembre 2020, par freddy

  I'm trying to stream my microphone input via HTTP using ffmpeg, so I can stream it in HTML. I run the following ffmpeg command :

  


  ffmpeg -f avfoundation -i ":1" -c:a libmp3lame -f mp3 -r 30 http://localhost:809

  


  It, however, crashes with the following error message :

  I've had success with streaming on that port using VLC, but it for some reason won't work using ffmpeg. Any ideas on how to fix this ?
