• 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,

• Streaming ALSA to rtsp stream using ffmpeg

  12 février 2019, par Demosthenes

  I would like to stream audio captured using an ALSA microphone with ffmpeg. I can capture the video to a file, what I want is ffmpeg to start an rtsp server which can be accessed by (multiple) clients in my local network. But I can’t even make it work with one client so far.

  What I tried so far :

  ffmpeg -f alsa -ac 1 -ar 44100 -i hw:1,0  -t 10 test.wav

  This is working perfectly. File is saved and can be played back. So input is alright.

  ffmpeg -f alsa -ac 1 -ar 44100 -i hw:1,0  -f rtsp rtsp_transport tcp rtsp://localhost:8090/live.sdp

  Trying this dry will result in an error it cannot connect to the server. Which is odd, I want to tell ffmpeg to start a server. So I’m starting one using

  ffserver ffserver.conf

  with a config file containing

  Port 8090
  
  BindAddress 0.0.0.0
  
  MaxHTTPConnections 2000
  
  MaxClients 1000
  
  MaxBandwidth 1000
  
  CustomLog -
  
  NoDaemon
  
  <feed>
  
  </feed>

  This starts a server, or so it would seem. Now, trying the ffmpeg command from above again, I get

  [tcp @ 0x11d2490] Connection to tcp://localhost:8090?timeout=0 failed (Connection refused), trying next address
  
  Could not write header for output file #0 (incorrect codec parameters ?): Invalid data found when processing inputStream mapping:
  
    Stream #0:0 -> #0:0 (pcm_s16le (native) -> aac (native))
  
      Last message repeated 1 times

  So I thought, maybe I should state an output codec, so :

  ffmpeg -f alsa -ac 1 -ar 44100 -i hw:1,0 -codec:a libmp3lame -q:a 2  -f rtsp rtsp_transport tcp rtsp://localhost:8090/live.sdp

  which gives pretty much the same error, just with a different codec :

  [tcp @ 0x24d8630] Connection to tcp://localhost:8090?timeout=0 failed (Connection refused), trying next address
  
  Could not write header for output file #0 (incorrect codec parameters ?): Invalid data found when processing inputStream mapping:
  
    Stream #0:0 -> #0:0 (pcm_s16le (native) -> mp3 (libmp3lame))
  
      Last message repeated 1 times

  Any hints to what I am missing ?
