RTMPDump v2.4
(c) 2010 Andrej Stepanchuk, Howard Chu, The Flvstreamer Team; license: GPL
rtmpdump: This program dumps the media content streamed over RTMP.
--help|-h Prints this help screen.
--rtmp|-r url URL (e.g. rtmp://host[:port]/path)
--host|-n hostname Overrides the hostname in the rtmp url
--port|-c port Overrides the port in the rtmp url
--socks|-S host:port Use the specified SOCKS proxy
--protocol|-l num Overrides the protocol in the rtmp url (0 - RTMP, 2 - RTMPE)
--playpath|-y path Overrides the playpath parsed from rtmp url
--playlist|-Y Set playlist before playing
--swfUrl|-s url URL to player swf file
--tcUrl|-t url URL to played stream (default: "rtmp://host[:port]/app")
--pageUrl|-p url Web URL of played programme
--app|-a app Name of target app on server
--swfhash|-w hexstring SHA256 hash of the decompressed SWF file (32 bytes)
--swfsize|-x num Size of the decompressed SWF file, required for SWFVerification
--swfVfy|-W url URL to player swf file, compute hash/size automatically
--swfAge|-X days Number of days to use cached SWF hash before refreshing
--auth|-u string Authentication string to be appended to the connect string
--conn|-C type:data Arbitrary AMF data to be appended to the connect string
B:boolean(0|1), S:string, N:number, O:object-flag(0|1),
Z:(null), NB:name:boolean, NS:name:string, NN:name:number
--flashVer|-f string Flash version string (default: "MAC 10,0,32,18")
--live|-v Save a live stream, no --resume (seeking) of live streams possible
--subscribe|-d string Stream name to subscribe to (otherwise defaults to playpath if live is specifed)
--flv|-o string FLV output file name, if the file name is - print stream to stdout
--resume|-e Resume a partial RTMP download
--timeout|-m num Timeout connection num seconds (default: 30)
--start|-A num Start at num seconds into stream (not valid when using --live)
--stop|-B num Stop at num seconds into stream
--token|-T key Key for SecureToken response
--hashes|-# Display progress with hashes, not with the byte counter
--buffer|-b Buffer time in milliseconds (default: 36000000)
--skip|-k num Skip num keyframes when looking for last keyframe to resume from. Useful if resume fails (default: 0)
--quiet|-q Suppresses all command output.
--verbose|-V Verbose command output.
--debug|-z Debug level command output.
If you don't pass parameters for swfUrl, pageUrl, or auth these properties will not be included in the connect packet.どうやらrtmpdumpにはmp3への変換機能が無いようです（分かってなかった）。

mini:~ admin$ lame --help
LAME 64bits version 3.99.5 (http://lame.sf.net)
usage: lame [options] <infile> [outfile]
<infile> and/or <outfile> can be "-", which means stdin/stdout.
RECOMMENDED:
lame -V2 input.wav output.mp3
OPTIONS:
-b bitrate set the bitrate, default 128 kbps
-h higher quality, but a little slower. Recommended.
-f fast mode (lower quality)
-V n quality setting for VBR. default n=4
0=high quality,bigger files. 9=smaller files
--preset type type must be "medium", "standard", "extreme", "insane",
or a value for an average desired bitrate and depending
on the value specified, appropriate quality settings will
be used.
"--preset help" gives more info on these
