DESCRIPTION
rtmpgw is a server for streaming media content from RTMP out to HTTP.
rtmpgw listens for HTTP requests that specify RTMP stream parameters
and then returns the RTMP data in the HTTP response. The only valid
HTTP request is "GET /" but additional options can be provided in URL-
encoded fashion. Options specified on the command line will be used as
defaults, which can be overridden by options in the HTTP request.
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 can-
not 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 de-
fault 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 speci-
fied 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 sub-
objects may be named, by prefixing the type with 'N' and speci-
fying 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 auto-
matically, 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 -d stream
Name of live stream to subscribe to. Defaults to playpath.
--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 20000.
--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 Se-
cureToken authentication.
--jtv -j JSON
JSON token used by legacy Justin.tv servers. Invokes Net-
Stream.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 hexa-
decimal. The --swfsize option must always be used with this op-
tion.
--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 op-
tion.
--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 speci-
fied 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 recalcu-
lated 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 time-
stamp as before, it will not be retrieved again.
Miscellaneous
--device -D address
Listener IP address. The default is 0.0.0.0, i.e., any IP ad-
dress.
--sport -g port
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.
EXAMPLES
The HTTP request
GET /?r=rtmp:%2f%2fserver%2fmyapp&y=somefile HTTP/1.0
is equivalent to the rtrmpdump(1) invocation
rtmpdump -r rtmp://server/myapp -y somefile
Note that only the shortform (single letter) options are supported.
ENVIRONMENT
HOME The value of $HOME is used as the location for the .swfinfo
file.
FILES
$HOME/.swfinfo
Cache of SWF Verification information
