NetworkParameters
These options define how to connect to the media server.
--rtmp-rurl
URL of the server and media content.
--host-nhostname
Overrides the hostname in the RTMP URL.
--port-cport
Overrides the port number in the RTMP URL.
--protocol-lnumber
Overrides the protocol in the RTMP URL.
0 = rtmp
1 = rtmpt
2 = rtmpe
3 = rtmpte
4 = rtmps
5 = rtmpts
--socks-Shost:port
Use the specified SOCKS4 proxy.
ConnectionParameters
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-aapp
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-turl
URL of the target stream. Defaults to rtmp[e]://host[:port]/app/playpath.
--pageUrl-purl
URL of the web page in which the media was embedded. By default no value will be sent.
--swfUrl-surl
URL of the SWF player for the media. By default no value will be sent.
--flashVer-fversion
Version of the Flash plugin used to run the SWF player. The default is "LNX 10,0,32,18".
--auth-ustring
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-Ctype: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
SessionParameters
These options take effect after the Connect request has succeeded.
--playpath-ypath
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.
--live-v
Specify that the media is a live stream. No resuming or seeking in live streams is possible.
--subscribe-dstream
Name of live stream to subscribe to. Defaults to playpath.
--start-Anum
Start at num seconds into the stream. Not valid for live streams.
--stop-Bnum
Stop at num seconds into the stream.
--buffer-bnum
Set buffer time to num milliseconds. The default is 20000.
--timeout-mnum
Timeout the session after num seconds without receiving any data from the server. The default is
120.
SecurityParameters
These options handle additional authentication requests from the server.
--token-Tkey
Key for SecureToken response, used if the server requires SecureToken authentication.
--jtv-jJSON
JSON token used by legacy Justin.tv servers. Invokes NetStream.Authenticate.UsherToken
--swfhash-whexstring
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-xnum
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-Wurl
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-Xdays
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--device-Daddress
Listener IP address. The default is 0.0.0.0, i.e., any IP address.
--sport-gport
Listener port. The default is 80.
--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.
