• VLC cant read some audiotracks created by ffmpeg

  18 juin 2021, par skanarr

  I have two different .mkv files of the same movie. One contains the English, German, Italian, Spanish and French audio and subtitle tracks, the other contains Japanese Audio and Subtitle tracks. Since I want to have all tracks in one file I tried to 'merge' them using ffmpeg.

  


  $ ffmpeg -i Movie.mkv -i Movie_jp.mkv -map 0:v -map 0:a -map 1:a:2 -map 0:s map 1:s:1 -map 1:s:2 -map 1:s:3 -c:v copy -c:a copy -c:s copy tmp.mkv


  


  Full Command Output from ffmpeg
That is the command I used and even though it took a while, I got my tmp.mkv.
However Playing it in VLC none of the Tracks from Movie_jp.mkv are working properly.
There are short periods where there is audio and then it is gone again for some minutes.
Also tmp.mkv freezes at 4:44 and freezes VLC for some time, before only audio continues top play.
Looking under Messages this is what I got

  


  main error: module not functional
main error: failed to create audio output


  


  Then a bunch of warnings
and a ****load of

  


  main error: Timestamp conversion failed (delay 1000000, buffering 100000, bound 9000000)
main error: Could not convert timestamp XY for FFmpeg
main warning: early picture skipped


  


  And finally

  


  main error: buffer deadlock prevented


  


  (All Message from VLC )
I don't know what I did wrong. The Japanese tracks are working in Movie_jp.mkv.
The all non-japanese Tracks are still working in tmp.mkv.
Also there are working Tracks with the same codecs on tmp.mkv (dts) as well as subtitles (pgs).

  


• Why is ffmpeg-python throwing a codec error here ?

  15 octobre 2019, par TwentyPenguins

  I’m trying out ffmpeg-python for the first time and I’m hitting what looks like a complex error surprisingly early on.

  Here’s my complete code as it stands :

  from tkinter import filedialog
  
  import ffmpeg
  
  
  
  sourceFile = filedialog.askopenfile()
  
  targetFile = filedialog.asksaveasfilename()
  
  
  
  stream = ffmpeg.input(sourceFile, ss=0, format='mov')
  
  stream = ffmpeg.output(stream, targetFile, format='mp4')
  
  ffmpeg.run(stream)

  In my head, this ought to be simple. The user browses to an existing MOV file (a standard h264 file which ’normal’ FFmpeg.exe can handle no problem on a Windows command line), then selects an output file for an MP4 to be saved, then FFmpeg is called and an MP4 file is converted from the MOV.

  However, regardless of what source file I choose, I am always hitting this error :

    File "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\lib\site-packages\ffmpeg\_ffmpeg.py", line 85, in output
  
    File "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\lib\site-packages\ffmpeg\_run.py", line 285, in run_async
  
      args, stdin=stdin_stream, stdout=stdout_stream, stderr=stderr_stream
  
    File "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\lib\subprocess.py", line 775, in __init__
  
      restore_signals, start_new_session)
  
    File "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\lib\subprocess.py", line 1119, in _execute_child
  
      args = list2cmdline(args)
  
    File "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\lib\subprocess.py", line 530, in list2cmdline
  
      needquote = (" " in arg) or ("\t" in arg) or not arg
  
    File "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\lib\encodings\cp1252.py", line 23, in decode
  
      return codecs.charmap_decode(input,self.errors,decoding_table)[0]
  
  UnicodeDecodeError: 'charmap' codec can't decode byte 0x90 in position 41: character maps to <undefined>
  
  </undefined>

  The position number changes depending on the file but the error is always ’charmap’ codec can’t decode byte 0x90 in position [x] : character maps to < undefined >

  Please can somebody point me to where I may be going wrong on this one ? I feel the answer is staring me in the face but I’m not seeing it.
