• UnsupportedAudioFileException in LIUM Speaker Diarization after re-sampling

  14 septembre 2016, par RAVI D PARIKH

  I am trying to configure LIUM tool for speaker diarization. This question is a follow up of UnsupportedAudioFileException in LIUM Speaker Diarization

  I have tried re sampling the file using sox and ffmpeg

  I am new to any sorts of programming and i have followed all steps described in LIUM quick start guide and the above link. I still get the same error. I think my input file has issues related to header as mentioned by Nikolay Shmyrev in the above link however i have no clue on how to solve it.

  My code is as below :

  java –jar  C:\Users\Ravi\Desktop\LIUM_SpkDiarization-8.4.1.jar \ --fInputMask= C:\Users\Ravi\Desktop\converted_f2.wav--sOutputMask= C:\Users\Ravi\Desktop\converted_converted_2.seg -–help --doCEClustering

  Error :

  10:52.037 SEVERE AudioFeatureSetFa  FileNotFoundException
  
  java.io.FileNotFoundException:
  
          at java.io.FileInputStream.open0(Native Method)
  
          at java.io.FileInputStream.open(Unknown Source)

          at fr.lium.spkDiarization.libFeature.AudioFeatureSetFactory.MakeFeature(AudioFeatureSetFactory.java:207)
  
  </init>

  The input file is at https://drive.google.com/file/d/0B7Fqe9EX5JbgT09BcXpSREd4em8/view?usp=sharing

  Input File Name:converted_f2.wav

  I have put the command and the full output of the prompt in a word document at

  https://drive.google.com/file/d/0B7Fqe9EX5JbgUUl6THNCZFgxRnM/view?usp=sharing

  The inpiut file has correct sampling rate and other parameters and thus i am not able to understand the cause of the error.
  Thanks a lot for the help

  Regards,
  Ravi

• create max quality Frame with FFMPEG from ProRes Clip

  5 août 2021, par Josef Zugarov

  I want to extract a frame from a ProRes Clip, recorded with a Blackmagic URSA Mini Pro 4.6K Gen 2 camera with ffmpeg.
I noticed the following : When I import the ProRes Clip into Davinci I can recover some highlights, which are out of the displayed range by lowering the gain paramater.
As you can see in the waveform the thrid peak has information in all channels.

  


  After I extracted the frame with ffmpeg, I couldn't recover the highlights anymore.
Waveform : Values are clipped till the fifth peak.

  


  I used the following command :
ffmpeg  -ss 00:00:01 -i 0volt.mov -vf zscale=t=input,zscale=c=input -frames:v 1  TIFFs\0volt.tiff -v verbose

  


  Here is the output of the ffmpeg command line : https://pastebin.com/a36ML3tL

  


  Do you have any hint, how the original quality and dynanmic range by extracting a TIFF-Frame with ffmpeg can be retained ?

  


  Thank you !
