• TCP connection refused with FFMPEG

  2 février 2017, par Samul

  OFFICIAL EDIT :

  I thank you so much for your help but I am still encountering problems.

  My ffserver.conf file is like this :

  # Port on which the server is listening. You must select a different
  
  # port from your standard HTTP web server if it is running on the same
  
  # computer.
  
  HTTPPort 8090
  
  
  
  # Address on which the server is bound. Only useful if you have
  
  # several network interfaces.
  
  HTTPBindAddress 0.0.0.0
  
  
  
  # Number of simultaneous HTTP connections that can be handled. It has
  
  # to be defined *before* the MaxClients parameter, since it defines the
  
  # MaxClients maximum limit.
  
  MaxHTTPConnections 2000
  
  
  
  # Number of simultaneous requests that can be handled. Since FFServer
  
  # is very fast, it is more likely that you will want to leave this high
  
  # and use MaxBandwidth, below.
  
  MaxClients 1000
  
  
  
  # This the maximum amount of kbit/sec that you are prepared to
  
  # consume when streaming to clients.
  
  MaxBandwidth 1000
  
  
  
  # Access log file (uses standard Apache log file format)
  
  # '-' is the standard output.

  # a path where the feed is stored on disk. You also specify the
  
  # maximum size of the feed, where zero means unlimited. Default:
  
  # File=/tmp/feed_name.ffm FileMaxSize=5M

  # You could specify
  
  # ReadOnlyFile /saved/specialvideo.ffm
  
  # This marks the file as readonly and it will not be deleted or updated.
  
  
  
  # Specify launch in order to start ffmpeg automatically.
  
  # First ffmpeg must be defined with an appropriate path if needed,

  I started my server and executed :

  ffserver -d -f /usr/share/doc/ffmpeg-2.6.8/ffserver.conf

  No error message and everything looks fine.

  After that I execute this (in your answer, I think you forgot the port number) :

  ffmpeg -i "rtsp://200.180.90.95:554/onvif1" -r 25 -s 640x480 -c:v libx264 -flags +global_header -f flv "http://45.79.207.38:8090/feed1.ffm"

• Extract Video Frames In Python

  I want to extract video frames and save them as image.

  import os, sys
  
  from PIL import Image
  
  
  
  a, b, c = os.popen3("ffmpeg -i test.avi")
  
  out = c.read()
  
  dp = out.index("Duration: ")
  
  duration = out[dp+10:dp+out[dp:].index(",")]
  
  hh, mm, ss = map(float, duration.split(":"))
  
  total = (hh*60 + mm)*60 + ss
  
  for i in xrange(9):
  
      t = (i + 1) * total / 10
  
      os.system("ffmpeg -i test.avi -ss %0.3fs frame%i.png" % (t, i))

  But I have this error :

  Note, the names of encoders and decoders dont always match, so there are
  
  several cases where the above table shows encoder only or decoder only entries
  
  even though both encoding and decoding are supported for example, the h263
  
  decoder corresponds to the h263 and h263p encoders, for file formats its even
  
  worse

  What is wrong in my code ? Thanks in advance
