What am i doing wrong?

[iamsumit]

Hi All,

I have been trying to learn how to use rtmpdump to run some of the online available sports stream in vlc. But havent been able to even run one single live stream without error. The only stream that i was able to run was not a live video. So, naturally i have hit a deadend.

My OS is MAC OS.

Try #1 -
http://desistreem.info/ten-cricket-stream/

Used wireshark for finding the attributes and made up this url:
rtmpdump -r "rtmp://37.48.81.7/live" -f "MAC 20,0,0,228" -W "http://www.p3g.tv/resources/scripts/eplayer.swf" -a "live" -p "http://www.p3g.tv/embedplayer/tencrizzerter/2/600/400" -y "tencrizzerter?id=11153&pk=8a1d406a630ad872d5b5454 fb8801d6202815f7c187b2e8cf0d2fe2348909dd7" -o- | vlc -

But it wouldn't work. It would give error:
core stream error: cannot pre fill buffer

What am i doing wrong here? Do i need a token?
Also i have noticed, i get this error for most of the links pasted by other members in this forum. Is there something wrong in my rtmpdump installation. Is there a test link to test?

Try # 2-
http://cricfree.sx/sky-sports-1-live-stream-new

Now wireshark not even detects anything under rtmpt filter!
What is happening wrong now? Isn't this rtmp protcol?

Please need some advice on how to proceed further or even what guides to read to understand where i am going wrong. And is wireshark the right choice for sniffing etc

Thanks you in advance.
Looking forward to diving deep into it once again after your valuable inputs. Thanks.
