NAME

rtmpdump - RTMP streaming media client  

SYNOPSIS

rtmpdump -r url [-n hostname] [-c port] [-l protocol] [-S host:port] [-a app] [-t tcUrl] [-p pageUrl] [-s swfUrl] [-f flashVer] [-u auth] [-C conndata] [-y playpath] [-Y] [-v] [-d subscription] [-e] [-k skip] [-A start] [-B stop] [-b buffer] [-m timeout] [-T key] [-w swfHash] [-x swfSize] [-W swfUrl] [-X swfAge] [-o output] [-#] [-q] [-V] [-z]
rtmpdump -h  

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.
--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.
--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
