[ffmpeg with librtmp] Problem downloading from Justin.tv

(http://stream-recorder.com/forum/showthread.php?t=10104)

I have trouble saving from justin.tv using ffmpeg that have librtmp enable, although I did manage success with another site, veemi for example.

Code:

ffmpeg -i "rtmp://68.68.30.184/live/_definst_ app=live/_definst_ pageUrl=http://www.veemi.com/embed.php?v=locapasion4&vw=650&vh=450 swfurl=http://www.veemi.com/player/player-licensed.swf playpath=locapasion4" -acodec copy -vcodec copy dump.flv

and if I try to save the video from justin.tv it always failed. this one for example

Code:

ffmpeg -i "rtmp://199.9.251.72/app pageUrl=http://www.twitch.tv/peacefuljay swfUrl=http://www-cdn.justin.tv/widgets/live_site_player.r3262f88719e6b856324ee5dd5d8b1d7595cf76b4.swf playpath=jtv_27Eo5oNZ4_YFwD3u jtv="5ecae6814a36f8ccc0e4c5d4d0cbfdf2381b4b9a:{\"swfDomains\": [\"justin.tv\", \"jtvx.com\", \"xarth.com\", \"twitchtv.com\", \"twitch.tv\", \"wdtinc.com\", \"imapweather.com\", \"facebook.com\", \"starcrafting.com\"], \"streamName\": \"jtv_27Eo5oNZ4_YFwD3u\", \"expiration\": 1317238268.588141, \"server\": \"video44-1\"}" swfVfy=1"  -acodec copy -vcodec copy dump.flv

dunno where I did wrong. does librtmp works differently on ffmpeg?
please help about this. Thanks

Re: [ffmpeg with librtmp] Problem downloading from Justin.tv

just realized about special character on librtmp.

Quote:

Additional options may be specified by appending space-separated key=value pairs to the URL. Special characters in values may need to be escaped to prevent misinterpretation by the option parser. The escape encoding uses a backslash followed by two hexadecimal digits representing the ASCII value of the character. E.g., spaces must be escaped as \20 and backslashes must be escaped as \5c.

does anyone know about this?
please help me with some explanation about what special character that need to be replace with ASCII value on librtmp as I try to find on google and can't find any. Thanks

Any specific reason to use ffmpeg and not rtmpdump?

p.s. You can always pipe output
