• How to disable slf4j log in java

  12 février, par Model123123

  Sorry for my poor English.

  


  I'm using ffmpeg-cli-wrapper library in java

  


  [main] INFO net.bramp.ffmpeg.RunProcessFunction - .\ffprobe.exe -version

  


  [main] INFO net.bramp.ffmpeg.RunProcessFunction - .\ffprobe.exe -v quiet -print_format json -show_error -show_format -show_streams -show_chapters

  


  How to remove this log ?

  


  try this :

  


  


  1. java.util.logging.Logger.getLogger("net.bramp.ffmpeg").setLevel(Level.OFF) ;

     


  


  2. /logger name="net.bramp.ffmpeg" level="OFF"/ in logback.xml

     


  


  


  but not work...

• ffmpeg from .mp3 to .al appears to slow and deepen the audio

  6 juillet 2020, par Darpeh

  I have an mp3 input file that is 22050Hz and 48kb/s. I need to convert it to a .al file in order to stream it to a camera on my network for output.

  


  ffmpeg -i file.mp3 file.al 


  


  creates a file that does play but the bitrate of the output is 176kb/s and it clearly slower/deeper sounding. I have tried -b:a 48k and -filter:a without success but I could be doing it wrong.

  


  Documentation states that this is the format I need : PCM ADPCM G.711A G.711.Mu G.726 G.729 MPEG2 AMR AAC

  


• FFmpeg av_register_all() memory leak

  1er septembre 2015, par Joe Allen

  I made a conversion function and I started to figure out the memory leaks.I started by make a small program to figure out the leaks but for some reason av_register_all() is also getting a memory leak. Is there something that I am suppose to free ?

  main.cpp :
