       rtmpdump is a tool for dumping media content streamed over RTMP.

       rtmpdump  makes a connection to the specified RTMP server and plays the media specified by
       the given url.  The url should be of the form

       Plain rtmp, as well as tunneled and encrypted sessions are supported.


   Network Parameters
       These options define how to connect to the media server.

       --rtmp         -r url
              URL of the server and media content.

       --host         -n hostname
              Overrides the hostname in the RTMP URL.

       --port         -c port
              Overrides the port number in the RTMP URL.

       --protocol     -l number
              Overrides the protocol in the RTMP URL.
                0 = rtmp
                1 = rtmpt
                2 = rtmpe
                3 = rtmpte
                4 = rtmps
                5 = rtmpts

       --socks        -S host:port
              Use the specified SOCKS4 proxy.

   Connection Parameters
       These options define the content of the RTMP Connect request packet.   If  correct  values
       are not provided, the media server will reject the connection attempt.

       --app          -a app
              Name of application to connect to on the RTMP server. Overrides the app in the RTMP
              URL. Sometimes the rtmpdump URL parser cannot determine the app name automatically,
              so it must be given explicitly using this option.

       --tcUrl        -t url
              URL of the target stream. Defaults to rtmp[e]://host[:port]/app/playpath.

       --pageUrl      -p url
              URL  of  the  web page in which the media was embedded. By default no value will be

       --swfUrl       -s url
              URL of the SWF player for the media. By default no value will be sent.

       --flashVer     -f version
              Version of the Flash plugin used to  run  the  SWF  player.  The  default  is  "LNX

       --auth         -u string
              An  authentication  string to be appended to the Connect message. Using this option
              will append a Boolean TRUE and then the specified string.  This option is only used
              by some particular servers and is deprecated. The more general --conn option should
              be used instead.

       --conn         -C type:data
              Append arbitrary AMF data to the Connect message. The type must be B for Boolean, N
              for  number,  S for string, O for object, or Z for null. For Booleans the data must
              be either 0 or 1 for FALSE or TRUE, respectively. Likewise  for  Objects  the  data
              must  be  0  or 1 to end or begin an object, respectively. Data items in subobjects
              may be named, by prefixing the type with 'N' and specifying  the  name  before  the
              value,  e.g.   NB:myFlag:1.  This  option  may  be used multiple times to construct
              arbitrary AMF sequences. E.g.
                -C B:1 -C S:authMe -C O:1 -C NN:code:1.23 -C NS:flag:ok -C O:0

   Session Parameters
       These options take effect after the Connect request has succeeded.

       --playpath     -y path
              Overrides the playpath parsed from the RTMP URL. Sometimes the rtmpdump URL  parser
              cannot determine the correct playpath automatically, so it must be given explicitly
              using this option.

       --playlist          -Y
              Issue a set_playlist command before sending the play  command.  The  playlist  will
              just contain the current playpath.

       --live         -v
              Specify  that the media is a live stream. No resuming or seeking in live streams is

       --subscribe    -d stream
              Name of live stream to subscribe to. Defaults to playpath.

       --realtime     -R
              Download  approximately  in  realtime,  without  attempting   to   speed   up   via
              Pause/Unpause  commands  ("the BUFX hack").  Useful for servers that jump backwards
              in time at the Unpause command.  Resuming and seeking in realtime streams is  still

       --resume       -e
              Resume an incomplete RTMP download.

       --skip         -k num
              Skip  num  keyframes  when looking for the last keyframe from which to resume. This
              may be useful if a regular attempt to resume fails. The default is 0.

       --start        -A num
              Start at num seconds into the stream. Not valid for live streams.

       --stop         -B num
              Stop at num seconds into the stream.

       --buffer       -b num
              Set buffer time to num milliseconds. The default is 36000000.

       --timeout      -m num
              Timeout the session after num seconds without receiving any data from  the  server.
              The default is 120.

   Security Parameters
       These options handle additional authentication requests from the server.

       --token        -T key
              Key   for   SecureToken   response,   used   if  the  server  requires  SecureToken

       --jtv          -j JSON
              JSON     token     used     by     legacy      servers.      Invokes

       --swfhash      -w hexstring
              SHA256  hash  of the decompressed SWF file. This option may be needed if the server
              uses SWF Verification, but see the --swfVfy option below. The hash is 32 bytes, and
              must  be  given  in hexadecimal. The --swfsize option must always be used with this

       --swfsize      -x num
              Size of the decompressed SWF file. This option may be needed if the server uses SWF
              Verification,  but  see the --swfVfy option below. The --swfhash option must always
              be used with this option.

       --swfVfy       -W url
              URL of the SWF player for this  media.  This  option  replaces  all  three  of  the
              --swfUrl,  --swfhash,  and  --swfsize  options.  When  this option is used, the SWF
              player is retrieved from the specified URL and  the  hash  and  size  are  computed
              automatically. Also the information is cached in a .swfinfo file in the user's home
              directory, so that it doesn't need to be  retrieved  and  recalculated  every  time
              rtmpdump  is  run.  The .swfinfo file records the URL, the time it was fetched, the
              modification timestamp of the SWF file, its size, and its  hash.  By  default,  the
              cached info will be used for 30 days before re-checking.

       --swfAge       -X days
              Specify  how  many  days  to  use  the cached SWF info before re-checking. Use 0 to
              always check the SWF URL. Note that if the check shows that the SWF  file  has  the
              same modification timestamp as before, it will not be retrieved again.

       --flv          -o output
              Specify the output file name. If the name is - or is omitted, the stream is written
              to stdout.

       --hashes       -#
              Display streaming progress with a hash mark for each 1% of progress, instead  of  a
              byte counter.

       --quiet        -q
              Suppress all command output.

       --verbose      -V
              Verbose command output.

       --debug        -z
              Debug level output. Extremely verbose, including hex dumps of all packet data.

       --help         -h
              Print a summary of command options.


       0      Successful program execution.

       1      Unrecoverable error.

       2      Incomplete transfer, resuming may get further.


       HOME   The value of $HOME is used as the location for the .swfinfo file.
