• ffmpeg Video thumbnail Service

  26 avril 2014, par user3576217

  I need active FFMPEG Video thumbnail Service. I have installed just FFMPEG but see Video thumbnail Service not working. I checked ffmpeg version on SSH and got this

  ffmpeg version 2.2.1 Copyright (c) 2000-2014 the FFmpeg developers
    built on Apr 13 2014 13:00:18 with gcc 4.4.6 (GCC) 20120305 (Red Hat 4.4.6-4)

  is their any way to enable just video thumbnail service ?

• Automator Service to Run Bash Script to Convert Video

  1er mars 2017, par mike varela

  I’m having the hardest time understanding variables in automator. In essence, I’m attempting to right click on a file and perform a bash script that I write. The issue I have is the bash script takes an input filename and output filename and ideally I want them to be the same, except for the output to be appended with something to indicate it’s converted.

  I’m using FFMBC (a derivative of FFMPEG)

  my script is

  ffmbc -i input.mov -vcodec prores -profile proxy -pix_fmt yuv422p10le -acodec pcm_s24le output.mov

  I’d like to change the output.mov to filename-proxy.mov

  So frustrated at the moment.

• Python ThreadedTCPServer : "Name or service not known"

  11 avril 2014, par Hal

  I was developing a ThreadedTCPServer to communicate with a PHP application also residing in this same machine. This is suppose to receive requests from this PHP app and to convert some videos locally using ffmpeg.

  Here's the code :

  # -*- coding: utf-8 -*- 
  
  import os
  
  import socket
  
  import threading
  
  import logging.config
  
  import SocketServer, time
  
  from queuev2 import QueueServer
  
  
  
  logging.basicConfig(format='[%(asctime)s.%(msecs).03d] %(message)s', datefmt='%Y-%m-%d %H:%M:%S', filename=os.path.join(os.path.dirname(os.path.realpath(__file__)), 'converter.log'), level=logging.INFO)
  
  
  
  class ThreadedTCPRequestHandler(SocketServer.BaseRequestHandler):
  
  
  
      def handle(self):
  
          data = self.request.recv(1024)
  
          cur_thread = threading.current_thread()
  
          response = "{}: {}".format(cur_thread.name, data)
  
          videoPool.add(data)
  
          print "Output! %s" % data
  
          self.request.sendall(response)
  
  
  
  class ThreadedTCPServer(SocketServer.ThreadingMixIn, SocketServer.TCPServer):
  
      pass
  
  
  
  if __name__ == "__main__":
  
  
  
      logging.info("Initializing...")
  
      videoPool = QueueServer()
  
      HOST, PORT = "localhost", 6666
  
  
  
      server = ThreadedTCPServer((HOST, PORT), ThreadedTCPRequestHandler)
  
      ip, port = server.server_address
  
  
  
      # Start a thread with the server -- that thread will then start one
  
      # more thread for each request
  
      server_thread = threading.Thread(target=server.serve_forever)
  
  
  
      # Exit the server thread when the main thread terminates
  
      server_thread.daemon = True
  
      server_thread.start()
  
  
  
      print("Server loop running in thread: %s" % server_thread.name)
  
  
  
      # "Groundhog day" time
  
      while True:
  
          time.sleep(999)
  
          pass
  
  
  
      #server.shutdown()

  This works well in my development laptop, but on the server i'm getting the following error :

  Traceback (most recent call last):
  
    File "server.py", line 31, in <module>
  
      server = ThreadedTCPServer((HOST, PORT), ThreadedTCPRequestHandler)
  
    File "/usr/lib/python2.7/SocketServer.py", line 408, in __init__
  
      self.server_bind()
  
    File "/usr/lib/python2.7/SocketServer.py", line 419, in server_bind
  
      self.socket.bind(self.server_address)
  
    File "/usr/lib/python2.7/socket.py", line 224, in meth
  
      return getattr(self._sock,name)(*args)
  
  socket.gaierror: [Errno -2] Name or service not known
  
  </module>

  I'm guessing it has to do with the port I'm using (6666), but I've tried others and it hasn't been working. Would Unix Domain Sockets be of use here ? Can you give me an example ?
