• Split Video Files and Make them individually playable

  21 juillet 2013, par rash

  I am newbie to this python. I split webm video file into chunks, but i couldn't able to make them individually playable using python program.But it plays after I join the chunks to a single file. I know its due to the absence of header file. Please help me with the codes to attach the header file to the parts to make them indiviually playable. Please reply. Thanks alot in advance.

  Here is the code :

  Client side :

  import socket, os
  
  import time
  
  
  
  client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
  
  client_socket.connect(("localhost", 5005))
  
  size = 1024
  
  
  
  while True:
  
      fname = "/home/xincoz/test/conn2.webm"
  
      fn = client_socket.recv(1024)
  
      print fn
  
  
  
      fp = open(fname,'wb')
  
      while True:
  
          strng = client_socket.recv(int(fn))
  
          print strng
  
          if not strng:
  
              break
  
          fp.write(strng)
  
      fp.close()
  
  
  
      print "Data Received successfully"
  
      exit()

  Server side :

  import os,kaa.metadata  
  
  import sys,time 
  
  import socket
  
  import Image
  
  
  
  server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
  
  server_socket.bind(("localhost", 5005))
  
  server_socket.listen(5)
  
  
  
  client_socket, address = server_socket.accept()
  
  print "Conencted to - ",address,"\n"
  
  
  
  file = '/home/xincoz/Downloads/connect.webm'
  
  a = kaa.metadata.parse(file)
  
  
  
  print '\n Maybe, pending work'
  
  file_name = open(file,'rb')
  
  size=str(os.path.getsize(file))
  
  print size
  
  client_socket.send(str(os.path.getsize(file)))
  
  print file_name
  
  strng = file_name.read(os.path.getsize(file))
  
  client_socket.send(strng[0:2000000])
  
  file_name.close()
  
  
  
  print str(a)+"Meta Data"
  
  print "Data sent successfully"

• online free media hosting for live streaming

  30 novembre 2013, par Abdul Ali

  wanted to ask two things :

  1- How can we put the output of FFMPEG to a stream (online address to put the stream).

  2- Is there any free service (for testing purpose) to use FFMPEG and pass the output to it for live streaming .

  apologies if am unable to explain properly what is intended.

  to summarize, wish to convert images to video using FFMPEG (have tried the image to video conversion locally and seems to be working) and put the output to an online resource for live streaming and possibly also have VOD (so users who later logon can view at least from some point behind which they have missed).

  regards,

• Who Invented FLIC ?

  26 mai 2011, par Multimedia Mike — Multimedia History

  I have been reading through “All Your Base Are Belong To Us : How 50 Years of Video Games Conquered Pop Culture” by Harold Goldberg. Despite the title, Zero Wing has yet to be mentioned (I’m about halfway done).

  
  
  

  I just made it through the chapter describing early breakthrough CD-ROM games, including Myst, The 7th Guest, and The 11th Hour. Some interesting tidbits :

  The 7th Guest
  Of course, Graeme Devine created a new FMV format (called VDX, documented here) for The 7th Guest. The player was apparently called PLAY and the book claims that Autodesk was so impressed by the technology that it licensed the player for use in its own products. When I think of an Autodesk multimedia format, I think of FLIC. The VDX coding format doesn’t look too much like FLIC, per my reading.

  Here’s the relevant passage (pp 118-119) :

  Devine began working on creating software within the CD-ROM disk that would play full-motion video. Within days he had a robust but small ninety-kilobyte player called PLAY that was so good, it was licensed by Autodesk, the makers of the best 3-D animation program at the time. Then Devine figured out a way to compress the huge video files so that they would easily fit on two CD-ROMs.

  Googling for “autodesk trilobyte play program” (Trilobyte was the company behind 7th Guest) led me to this readme file for a program called PLAY73 (hosted at Jason Scott’s massive CD-ROM archive, and it’s on a disc that, incidentally, I donated to the archive ; so, let’s here it for Jason’s tireless archival efforts ! And for Google’s remarkable indexing prowess). The file — dated September 10, 1991 — mentions that it’s a FLICK player, copyright Trilobyte software.

  
  
  

  However, it also mentions being a Groovie Player. Based on ScummVM’s reimplementation of the VDX format, Groovie might refer to the engine behind The 7th Guest.

  So now I’m really interested : Did Graeme Devine create the FLIC file format ? Multimedia nerds want to know !

  I guess not. Thanks to Jim Leonard for digging up this item : “I developed the flic file format for the Autodesk Animator.” Jim Kent, Dr. Dobbs Magazine, March 1993.

  The PLAY73 changelog reveals something from the bad old days of DOS/PC programming : The necessity of writing graphics drivers for 1/2 dozen different video adapters. The PLAY73 readme file also has some vintage contact address for Graeme Devine ; remember when addresses looked like these ?

  The 11th Hour
  The book didn’t really add anything I didn’t already know regarding the compression format (RoQ) used in 11th Hour. I already knew how hard Devine worked at it. This book took pains to emphasize the emotional toll taken on the format’s creator.

  I wonder if he would be comforted to know that, more than 15 years later, people are still finding ways to use the format.
