  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Transcoding to H264. PTS and DTS sync accross multiple output streams with different bitrates

    25 mars 2019, par timmytimmers

    I have a setup where I am transcoding live feeds from OTA broadcasts to H264 using the Nvidia NVENC encoder. I am also transcoding the audio to AAC. We are trying to output 3 cbr streams and various bitrates. The problem I am running into is that the PTS and DTS on the multiple outputs are not aligning which is critical for our use case. I am hoping there is an easy fix to this but I have not yet been able to locate one. Any thoughts on how to accomplish this ?

    These streams will be eventually mux’d back together for DRM insertion into a ABR stream. Without those values being in sync it will not be ABR compliant.

  • ffmpeg clean all noise background silences in a poscast

    23 mars 2019, par fireDevelop.com

    I have hundreds of podcast without music, just the voice and the room silence.
    In the silences, I have many clicks, respirations, etc...
    I need to clean all silences with a script, keeping intact the voice.

    In this picture you can see my dirty silences

    And here the result I want in all my audios

    When I use some scripts of sox. I don`t get the result I spect because the voice is affected by the script, the room-silence disappear and some clic still in the silences.

    Then in order to keep intact the voice, I want to do this :

    1. Delete all the silences longer than 3 seconds.

    1. Split all the audio and silences with in a sequence numbers. ie. :

      • 001-Silence-2.0seconds.wav
      • 002-voice.wav
      • 003-Silence-0.25seconds.wav
      • 004-voice.wav
      • 005-Silence-0.75seconds.wav
      • 006-voice.wav
      • ...
      • ...

    1. Before, run the script I created manually many files with silences of diferents silences I will use :

      • myManuallySilence-0.25seconds.wav
      • myManuallySilence-0.50seconds.wav
      • myManuallySilence-0.75seconds.wav
      • myManuallySilence-0.1seconds.wav
      • myManuallySilence-1.25seconds.wav
      • ...
      • ...
      • myManuallySilence-2.50seconds.wav
      • myManuallySilence-2.75seconds.wav
      • myManuallySilence-3.0seconds.wav
    1. the script will check the dirty silences duration and replace by the files myManuallySilence-x.xseconds.wav
    1. merge all files in one wav file, with the original voice and all the silences cleanned.

    At the moment I have only this script :

    # get the path of Adobe Audition and add timestamp in the output 
    
filename
    
fileName=out
    
current_time=$(date "+%Y.%m.%d-%H.%M.%S")
    
newFileName=$fileName.$current_time.wav
    
#yourPathAPP=/Applications/Adobe\ Audition\ CC\ 2019/Adobe\ Audition\ 
    
CC\ 2019.app
    
yourPathAPP=/Volumes/6TB/Applications/ocenaudio.app
    
# # 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 $newFileName noisered noise.prof 0.50
    
# # Split audio by noise
    
 sox -V3 $newFileName output.wav silence 1 00:00:02.000 - 80d 1 
    
 00:00:02.000 -80d : newfile : restart
    

    
# ####### (these settings worked for my computer mic - maybe we need to 
    
finetune them later) #######

    Is getting all the voice in separate files like this :
    output001.wav
    output002.wav
    output003.wav
    output004.wav
    ...
    output00x.wav

    Please, any suggestion will be appreciated.
    Thanks so much in advance !
