• How to create thumbnail about torrent without downloading video files ? [on hold]

  1er septembre 2019, par tty78

  Most of time, torrent sites like RARBG/The Pirate Bay/KickAss would return many query results even through I have typed in many detailed keywords, which is not strange because there are many people upload it.

  So, when i want to watch/download a torrent movie, it’s better to check the video first to find out that :

  • is it a fake video
  • is the video watermarked
  • is there some AD in the video
  • is it 1980*1080 or 640*480 ??

  What i want to do is creating thumbnail of the videos without download them, so that i can save a lot of broadband, disk space and time.

  Now I can create thumbnail with a python tool - vcsi, but it depends on the video file stored in disk.
  In fact, vcsi get meta information with ffprobe and create thumbnail using ffmpeg.

  def probe_media(self, path):
  
      """Probe video file using ffprobe
  
      """
  
      ffprobe_command = [
  
          "ffprobe",
  
          "-v", "quiet",
  
          "-print_format", "json",
  
          "-show_format",
  
          "-show_streams",
  
          path
  
      ]
  
  
  
      try:
  
          output = subprocess.check_output(ffprobe_command)
  
          self.ffprobe_dict = json.loads(output.decode("utf-8"))
  
      except FileNotFoundError:
  
          error = "Could not find 'ffprobe' executable. Please make sure ffmpeg/ffprobe is installed and is in your PATH."
  
          error_exit(error)

  ffmpeg_command = [
  
          "ffmpeg",
  
          "-ss", skip_time,
  
          "-i", self.path,
  
          "-ss", skip_delay,
  
          "-vframes", "1",
  
          "-s", "%sx%s" % (width, height),
  
      ]

  WebTorrent may be a solution but it’s not good because I have a lot of torrent file to scan.
  I want to create thumbnail on a ubuntu VPS because it can run day and night, and i can post thumbnail under the torrent comments.
  Some key frame, resolution and duration are enough, maybe.
  

• ffmpeg set data stream codec tag when copying

  19 mars 2021, par user972014

  I use ffmpeg to copy a data stream from one file to the other using -c copy

  


  The problem is that it causes the output file to have no codec tag string. How can I set it ?

  


  The name of the original stream was :

  


  Stream #0:3(eng): Data: none (gpmd / 0x646D7067), 96 kb/s (default)
    Metadata:
      creation_time   : 2020-09-08 16:35:49
      handler_name    : GoPro MET


  


  While for the output file I get it is :

  


  Stream #0:2[0x102]: Data: bin_data ([6][0][0][0] / 0x0006)


  


  I'm using a commandline similar to that :

  


  ffmpeg -i video.mp4 -map 0:3 -c copy -metadata:s:d codec_tag=xxxx -vcodec libx264 converted4.ts


  


  I also tried handler=... handler_name=...
