• 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.
  

• Stream over serial port using FFmpeg [closed]

  12 septembre 2020, par Rasoul Sharifian

  Is it possible to stream videos over the serial port using the FFmpeg library ? Or is there any other library that can compress and stream videos over serial ports ?
Now I am using the FFmpeg library to stream videos by UDP and LAN cables, but it must stream over the serial port.

  


  I also used a kind of Uart to ethernet converter hardware module to solve the problem and hopefully, this worked for me. But the project goal is to send video data over serial ports originally and not using some converters.

  


  Any suggestions would be helpful.
