• Encoding for HLS using FFMPEG results in have a decreasing DTS

  29 décembre 2014, par Luuk D. Jansen

  I am trying to encode video for HTS live streaming, but am having problems with validating the stream using Apple Media Validator (mediastreamvalidator).
  (my test file : http://dominicansinteractive.idoms.org/media/9536/playlist.m3u8)

  The output is :

  --------------------------------------------------------------------------------
  
  http://dominicansinteractive.idoms.org/media/9536/199/prog_index.m3u8
  
  --------------------------------------------------------------------------------
  
  
  
  Playlist Validation: 
  
  
  
      OK
  
  
  
  Segments:
  
  
  
  segment_00000.ts:
  
  
  
      ERROR: (-1) Decreasing DTS were detected in track 0
  
      ERROR: (-1) Decreasing DTS were detected in track 1

      Average segment structural overhead: 206525.83 bps (9.58 %)

  The second segment doesn’t seem to have the problem :

  This seems to be a serious problem for HLS, so I am looking if there is a way to fix this.

  When looking with FFMPEG at the encoded file I get (encoder output/command at the bottom of the email) :

  This problem does not occur with the BASELINE profile, but does with MAIN.

• Error converting .flv to .avi with ffmpeg

  5 juillet 2012, par user1504396

  When i try the 2d code, with a 5 minutes 7 second video, I get a 28 minutes 29 seconds video, What did I do wrong ?

  Here is the ffmpeg output :

  [Me@Hewlett-Packard Downloads]$ ffmpeg -i "0042473.flv" -s 400x240 -aspect 2:1 -r 20 -vcodec mjpeg -qscale 1 -acodec adpcm_ima_wav -ac 2 "VID_0001.AVI"

  Where is my problem ?

• Extract Video Frames In Python

  22 avril 2017, par TheNone

  I want to extract video frames and save them as image.

  import os, sys
  
  from PIL import Image
  
  
  
  a, b, c = os.popen3("ffmpeg -i test.avi")
  
  out = c.read()
  
  dp = out.index("Duration: ")
  
  duration = out[dp+10:dp+out[dp:].index(",")]
  
  hh, mm, ss = map(float, duration.split(":"))
  
  total = (hh*60 + mm)*60 + ss
  
  for i in xrange(9):
  
      t = (i + 1) * total / 10
  
      os.system("ffmpeg -i test.avi -ss %0.3fs frame%i.png" % (t, i))

  But I have this error :

  Note, the names of encoders and decoders dont always match, so there are
  
  several cases where the above table shows encoder only or decoder only entries
  
  even though both encoding and decoding are supported for example, the h263
  
  decoder corresponds to the h263 and h263p encoders, for file formats its even
  
  worse

  What is wrong in my code ? Thanks in advance
