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.
--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
