Capturing Local Copy of Akamai Stream

[HanFrolo]

I've read up some on capturing Akamai streams with KSV's script, but I can't seem to find the manifest file or .f4m url for the stream I want to save locally.

I found this in the Page Source:

// livestream embed parameters
LiveStream.embedPath = 'http://us.media.blizzard.com/blizzcon/2013/player.swf';
LiveStream.embedTargetId = 'video-container';
LiveStream.embedParams = {
useNativeFlashPlayer : true,
allowFullScreen : true,
AllowDVR : true,
homeOrderBy : 'new',
ipAddress : 'XX.XXX.XXX.XX',
externalUserId : 'kpHppI3YMou-Z-IhCg40Vbsu9Zbf8QxcUDg_TqblG29o7aJgJzFDx3k46nWVabL6eZq2GVQMGXxYm-2psKpc1TcLhb-qOrjTQlVdIPxXhTZz3D-AL3sUCgq1PmQDQMnvm3NwFm8l0Ihbg28MAPw1el3M4c9lz7XzPDGOLNqHYt8',
clientToken : 'AFFC05D0578E57F395796C35F654A33E22395CA3738FF1C00D8E70B947E501F4',
ChannelID : 'blizzcon2013_main_d1_ah_l',
distributor : 'blizzcon',
event : 'november',
userInactivityInterval : 2000,
mode : 'free'
};
//control data
LiveStream.controlData = {
"DAY1_ARCHIVE_READY": "true",
"STREAM_REQUIRES_LOG_IN": "false",
"DAY2_ARCHIVE_READY": "true",
"DAY2_BASETIME": "1384020000000",
"DAY1_BASETIME": "1383937200000",
"IS_STREAM_ENABLED": "true",
"SHOW_AJAX_SCHEDULE": "true"

With the network tab open in Chrome, this loads when I start playing the video:

http://blizzcon2013-lh.akamaihd.net/control/blizzsc2_day2_1_2800@s143458?cmd=log,rebufferevent,0.448&v=3.1.0.43&r=DSHOC&g=WTHNGXDTXJDE&lvl1=0.066,10,0.75,0,0,NaN,0,0,2,2800,0.486,1385252807.693,0.486,0,0.486,27527.684,179,NaN,0,0,0,0,u,false

Can someone break this down for me? I gather the 2800 in the url is the bitrate? and the @s143458 is some sort of start marker for the file.


When I simply 'Save_As' the URL above for any of the files like the one above, they only save a maximum 2GB file size and end abruptly. I'd like to find a way to save the entire broadcast of both days if possible, or find how to request the exact in/out points I need to download the segments and join them locally.


Thanks!

Posting a link to the page with the video would be helpful.

Stream is here:

http://us.battle.net/blizzcon/en/live-stream/

Ideally I would like the entire stream from each stage.

I got this link from URL Snooper.
http://blizzcon2013-lh.akamaihd.net/blizzsc2_day2_1_2800@s143458?v=3.1.0&fp=WIN%2011,9...a7e000304bd258

A 2 GB FLV file.

A 2 GB FLV file.

Right so that's the file I can find with Chrome's Network tab open. But it only loads the first 2GB of the stream.


Here's an example of URL's that load when I seek to different times in the stream:
@START

http://blizzcon2013-lh.akamaihd.net/blizzmain_day2_1_2800@s143454?v=3.1.0&fp=MAC%2011,9,900,152&r=YAOUD&g=ZWLSEXTPNGNJ&primaryToken=1385289561_ffa6f3b31f8284b62f19772380c25dc9

@1:00

...

@9:00

http://blizzcon2013-lh.akamaihd.net/blizzmain_day2_1_2800@s143454?v=3.1.0&fp=MAC%2011,9,900,152&r=YAOUD&g=ZWLSEXTPNGNJ&seek=32425.532172076066&transferToken=VqcPidSy&session=AQBKhcxJFwNiHs1jkVJjqnlysHECQqSCCKxCjGFTL5sLpetLuj0uhH0XvxURfagQrwrh1FNu

So each of those URL's have a

seek=

parameter in seconds from what I understand. The problem is everytime I try and download the stream from a certain timecode start by manipulating the URL in this way, I get this error message:

An error occurred while processing your request.
Reference #183.1e620317.1385260303.168a8b3

Any ideas?
