Which bug ? It works for me (under Ubuntu).

Anyway, multi-bitrate streams (240p, 360p, 720p, 1080p) use Akamai's regular FMS, UsherToken isn't needed.

Sample command that works :

toine512@toine512-VirtualBox:~/Bureau/rtmpdump-build$ ./rtmpdump -j "63b8de623d8060ca46535b1e18f627bc3e614181:{\"swfDomains\": [\"justin.tv\", \"jtvx.com\", \"xarth.com\", \"twitchtv.com\", \"twitch.tv\", \"wdtinc.com\", \"imapweather.com\", \"facebook.com\", \"starcrafting.com\"], \"streamName\": \"jtv__f21mA5gfzG_rqvm\", \"expiration\": 1311265516.8942881, \"server\": \"jfk01-video3-2\"}" -r rtmp://199.9.255.111/app/jtv__f21mA5gfzG_rqvm -s http://www-cdn.justin.tv/widgets/live_site_player.r8ae7cdf2fe5e11446646691ef54dff2195814fa1.swf -v -o out.flv

Under windows it's stripping all the quotes from variables which makes token invalid. for testing purposes i hardcoded the token value in program and only then was able to successfully download the stream.

[toine512]

So the problem is the command prompt, can you send me your Windows builds ? (I can't cross compile and I haven't a working Mingw/MSYS environment yet)

Thanks

[KSV]

sure, i will post it tommorow morning.

[toine512]

That's great.

[toine512]

I succeeded to cross compile under Ubuntu (read the README twice before posting ! ) !

Haha, Windows command prompt is so ugly ! I'll search tomorrow for the right escaping character or a solution with a batch script ...

[KSV]

I have further tested it. escape character in windows cmd shell is caret (^) but it didn't solved the problem. however using the backslash as escape character (same as in linux) it passes the correct value of token. so we just need to replace " with \" in token value to get it working.
