• What does -inf LUFS mean in the output of ffmpeg ?

  17 novembre 2020, par Bailey Brightman

  I've looked through the documentation but havent been able to figure out exactly what this means. Could it be an issue with the command I'm running ?

  


  Heres the command :
-i ${filePath} -af loudnorm=I=-16:dual_mono=true:TP=-1.5:LRA=11:print_format=summary -f null - 2>&1
And heres part of the output I'm getting :

  


  Output Integrated:    -inf LUFS
Output True Peak:    -17.2 dBTP
Output LRA:            0.0 LU
Output Threshold:    -70.0 LUFS


  


  I'm trying to use this information to ensure that audio is lower than a set LUFS Value

  


• Android : How to save two overlapped videos as one using mediacodec ?

  27 avril 2015, par Seba Niepodam

  I want to do something similar to this on android.

  I want to load video from file and display it twice with some transformations (mostly resize). And i want to encode it as one video file.

  Is it possible to do it in native android ? With mediacodec or in any other way ?

  I know there is a ffmpeg but i have trouble compiling it and working with Xamarin.
