DESCRIPTION

       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
         rtmp[t][e]://hostname[:port][/app[/playpath]]

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

OPTIONS

   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 sent.

       --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 10,0,32,18".

       --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 possible.

       --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 possible.

       --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 authentication.

       --jtv          -j JSON
              JSON token used by legacy Justin.tv servers. Invokes NetStream.Authenticate.UsherToken

       --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 option.

       --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.

   Miscellaneous
       --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.

EXIT STATUS

       0      Successful program execution.

       1      Unrecoverable error.

       2      Incomplete transfer, resuming may get further.

ENVIRONMENT

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

FILES

       $HOME/.swfinfo
              Cache of SWF Verification information
