• Why does an "ffmpeg fail" occur when trying to export frames from my "data_src.mp4" file, while using DeepFaceLab ?

  28 août 2020, par Toby Ryberg

  I've been following this step-by-step videoin installing and using DeepFaceLab on my Macbook Pro, which uses OS Catalina. I've been stuck at the step which begins at the 4:42 mark, where he enters this code :

  


  python main.py videoed extract-video —input-file WORKSPACE/data_src.mp4 —output-dir WORKSPACE/data_src

  


  After entering the command, I'm prompted to enter an FPS value ; no problem. Next, it asks for a file output type, which is where I get tied up— as far as I know. It appears as though I can enter either png or jpeg, but receive the same error message, which looks like this :

  


  / !\ ffmpeg fail, job commandline :['ffmpeg', '-i', '/Users/tobyryberg/Documents/deepfakes/DeepFaceLab/WORKSPACE/data_src.mp4', '-pix_fmt', 'rgb24', '/Users/tobyryberg/Documents/deepfakes/DeepFaceLab/WORKSPACE/data_src/%5d.png']

  


  I have no idea what went wrong, as I BELIEVE that I have been doing everything right thus far. If this is at all necessary information, I've opted to use an 18+ minute long video for my source clip, which is an .mp4 file, without audio. If there's someone out there who has the patience to work with me and figure out what went wrong, I'll be forever grateful !

  


• lavf/id3v2dec : support multiple values and TIPL frames

  lavf/id3v2dec : support multiple values and TIPL frames
  Fixes https://trac.ffmpeg.org/ticket/6949
  Ordinary text frames in ID3v2 are allowed to have multiple
  
  (null-separated) values. This technically isn't allowed in TXXX,
  
  but it's used in practice by Picard, and supporting it is harmless.
  TIPL/IPL (Involved People List) and TMCL (Musician Credits List) work
  
  similarly to TXXX, but alternate key-value-key-value.
