• Overlay system time with milliseconds in ffmpeg

  8 septembre 2017, par userDtrm

  I need to overlay the current system time with milliseconds in ffmpeg. The solutions I’ve come here across simply displays the pts or gmtime (doesn’t show milliseconds). Please find below the script that I’m currently using for this. This simply shows the pts time stamp.

  ffmpeg -f v4l2 -input_format yuyv422 -framerate 30 -s 640x480 -i /dev/video0 -filter_complex "drawtext=fontfile=/usr/share/fonts/truetype/freefont/FreeSerif.ttf: text='frame %{n}\\: %{pict_type}\\: pts=%{pts\\:hms}': x=100: y=50: fontsize=24: fontcolor=yellow@0.8: box=1: boxcolor=blue@0.9" -analyzeduration 5 -c:v libx264 -profile:v baseline -trellis 0 -subq 1 -level 32 -preset ultrafast -tune zerolatency -me_method epzs -r 50 -crf 20 -threads 0 -bufsize 1 -coder 0 -b_strategy 0 -bf 0 -sc_threshold 0 -x264-params vbv-maxrate=2000:vbv-bufsize=100:slice-max-size=200:keyint=10:min-keyint=10:partitions=-parti8x8-partp8x8:me=dia:qpmin=10:qpmax=51:qpstep=4:ref=1: -pix_fmt yuv420p -an -f mpegts - | nc -u 131.227.87.152 7001

  Can someone please let me know how to get the current system time with milliseconds into the ffmpeg output ?

  Thanks.

• 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 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
