• FFMpeg copy stream SEI type 162 error

  13 juillet 2015, par Vishal Shah

  I am using FFMpeg to copy an RTSP stream to an RTMP stream. Both of which are network streams. This is the command I am using.

  ffmpeg -re -i rtsp ://url.to/rtsp/stream -c copy -f flv rtmp ://target.rtmp/uri/stream

  I am receiving data on the youtube live control room. But After a point I get an error like this in my FFMpeg console and then the data transfer on youtube live stops.

  SEI type 162 size 1496 truncated at 1280

  Can someone throw light on what this error means and how to resolve it ?

  Note that the RTSP stream is over the network

• SoX - Remove noise only in silences

  15 mars 2019, par fireDevelop.com

  Please, I need to clean ONLY the noise in the silences of hundreds podcast, NOT in the audio voice. To do this I use this script :

  # First denoise audio
  
  
  
  ## Get noise sample
  
  ffmpeg -i in.wav -vn -ss 00:00:00 -t 00:00:01 noise-sample.wav
  
  
  
  ## Create noise profile
  
  sox noise-sample.wav -n noiseprof noise.prof
  
  
  
  ## Clean audio from noise
  
  sox in.wav clean.wav noisered noise.prof 0.21
  
  
  
  # Split audio by noise
  
  sox -V3 clean.wav output.wav silence 1 0.2 0.4% 1 0.2 0.4% : newfile : restart
  
  
  
  ####### (these settings worked for my computer mic - maybe we need to finetune them later) #######

  Here you can see my audio :
  My audio
  Please how can I said to the script don’t touch the audio voice ? If I run this script the audio voice is affected by the filter, and I want keep intact because sound good.

  Note, I don’t want a complete silence like -60db, I prefer keep some silence room, like gssgsssgsssss :)

  Thanks so much.

• Manage multipe IP cameras at the same time

  4 juin 2015, par Alessio

  How I can manage multiple GoPro cameras at the same time ? I want to stream three videos of three GoPro cameras at the same time and record the videos on the hard disk.

  I have written a tool in Java for one GoPro and it works correctly.

  Help me please !

  This is the code :
