title: TCP connection refused with FFMPEG
body: <p>OFFICIAL EDIT:</p>
  
  <p>I thank you so much for your help but I am still encountering problems.</p>
  
  <p>My ffserver.conf file is like this:</p>
  
  <pre><code># 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.

  ##################################################################
  # Definition of the live feeds. Each live feed contains one video
  # and/or audio sequence coming from an ffmpeg encoder or another
  # ffserver. This sequence may be encoded simultaneously with several
  # codecs at several resolutions.
  
  &lt;Feed feed1.ffm&gt;
  
  # You must use 'ffmpeg' to send a live feed to ffserver. In this
  # example, you can type:
  #
  # ffmpeg http://localhost:8090/feed1.ffm
  
  # ffserver can also do time shifting. It means that it can stream any
  # previously recorded live stream. The request should contain:
  # "http://xxxx?date=[YYYY-MM-DDT][[HH:]MM:]SS[.m...]".You must specify
  # 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
  File /tmp/feed1.ffm
  FileMaxSize 200K
  
  # 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,
  # after that options can follow, but avoid adding the http:// field
  #Launch ffmpeg
  
  # Only allow connections from localhost to the feed.
  #ACL allow 127.0.0.1
  #ACL allow 189.34.0.158
  &lt;/Feed&gt;
  
  
  ##################################################################
  # Now you can define each stream which will be generated from the
  # original audio and video stream. Each format has a filename (here
  # 'test1.mpg'). FFServer will send this stream when answering a
  # request containing this filename.
  
  &lt;Stream test1.mpg&gt;
  
  # coming from live feed 'feed1'
  Feed feed1.ffm
  
  # Format of the stream : you can choose among:
  # mpeg       : MPEG-1 multiplexed video and audio
  # mpegvideo  : only MPEG-1 video
  # mp2        : MPEG-2 audio (use AudioCodec to select layer 2 and 3 codec)
  # ogg        : Ogg format (Vorbis audio codec)
  # rm         : RealNetworks-compatible stream. Multiplexed audio and video.
  # ra         : RealNetworks-compatible stream. Audio only.
  # mpjpeg     : Multipart JPEG (works with Netscape without any plugin)
  # jpeg       : Generate a single JPEG image.
  # asf        : ASF compatible streaming (Windows Media Player format).
  # swf        : Macromedia Flash compatible stream
  # avi        : AVI format (MPEG-4 video, MPEG audio sound)

  # different bitrates.

  # Sampling frequency for audio. When using low bitrates, you should
  # lower this frequency to 22050 or 11025. The supported frequencies
  # depend on the selected audio codec.

  # Set this to the number of seconds backwards in time to start. Note that

  # ACL:
  
  # You can allow ranges of addresses (or single addresses)
  #ACL ALLOW &lt;first address&gt; &lt;last address&gt;
  
  # You can deny ranges of addresses (or single addresses)
  #ACL DENY &lt;first address&gt; &lt;last address&gt;
  
  # You can repeat the ACL allow/deny as often as you like. It is on a per
  # stream basis. The first match defines the action. If there are no matches,
  # then the default is the inverse of the last ACL statement.
  #
  # Thus 'ACL allow localhost' only allows access from localhost.
  # 'ACL deny 1.0.0.0 1.255.255.255' would deny the whole of network 1 and
  # allow everybody else.

  #
  # An SDP file is automatically generated by ffserver by adding the
  # 'sdp' extension to the stream name (here
  # http://localhost:8090/test1-sdp.sdp). You should usually give this
  # file to your player to play the stream.
  #
  # The 'NoLoop' option can be used to avoid looping when the stream is
  # terminated.
