• ffmpeg resize logo depending on video resolution with multiple outputs

  30 août 2022, par Panama Jack

  I'm having a tough time trying to get a logo above text in the lower right corner of my videos. The problem is depending on the video size and resolution the logo (image) is too big or too small. Sometimes it overlaps the text. How can I make it so that no matter what the resolution or ratio is, it scales proportionately and always above the text ? For example, videos of 1920x1080 at 16:9 or 1080x1920 9:16, or 1280x720 16:9 or 720x1280 9:16 and so on. Basically, it will always scale correctly on all outputs. Sometimes there might be more outputs but in this code sample there are 3 hls files. I tried scale2ref but can't get that to work and it makes my file sizes much bigger.

  


  Here's my current code.

  Yop, testé à l’instant sur SPIP 3.2.7 SVN, j’ai bien les logos (pb de cache ou autre chez toi ?).

  Hello :)
  Oui oui, je t’ai même fait une copie d’écran des réglages de spip et de la version de gd dans php si besoin.
