Rtmpdump fails half the way through

[naskoboy]

Hi friends,

I spent few days trying to capture this stream and I am exhausted.
Pls take a look and let me know if you have any idea what is going on.
Original link of the stream is http://tv.bnt.bg/bnt1/16x9/
however it's restricted only on territory of Bulgaria which I managed to overcome via a socks proxy.

RTMPDUMP debug session is attached as a file.
RTMPSUCK output generated from within Bulgaria is enclosed below.

Help appreciated.

post original link from stream or video

Hi hasomaso,

Thank you for your quick reply.
Original link is http://tv.bnt.bg/bnt1/16x9/
however server is restricting access only from within Bulgaria - that's why I use socks proxy.
Do you have access to proxy in BG ?
rtmpsuck output is enclosed above.

One detail which I hope shouldn't matter is that "rtmpsuck" was generated in within BG under Ubuntu whereas "rtmpdump" was executed outside BG on Win7 via proxy.

Thanks !

i have test the streams with BG proxy and i could start all 3 streams without problems under rtmpdump

stream "bnt1" and "bnt2" use secureToken

-T "B@1R1st1077"

and here all 3 streams with fullcode from rtmpdump

BNT1:

rtmpdump -v -r "rtmp://edge3.cdn.bg:2020/fls/bnt.stream?at=b397b371faf1b2347ebb6954893264f8" -a "fls" -W "http://cdn.bg/eflash/jwplayer510/player.swf" -p "http://cdn.bg/live/4eViE8vGzI" -y "bnt.stream?at=b397b371faf1b2347ebb6954893264f8" -T "B@1R1st1077" -o "bnt1.flv"

BNT2:

rtmpdump -v -r "rtmp://edge3.cdn.bg:2020/fls/bnt2.stream?at=b397b371faf1b2347ebb6954893264f8" -a "fls" -W "http://cdn.bg/eflash/jwplayer510/player.swf" -p "http://cdn.bg/live/ZBPbdxDHm7" -y "bnt2.stream?at=b397b371faf1b2347ebb6954893264f8" -T "B@1R1st1077" -o "bnt2.flv"

BNTWORLD:

rtmpdump -v -r "rtmp://193.43.26.22/live/livestream1" -a "live" -W "http://showww.bnt.bg/sat/myVideo.swf" -p "http://showww.bnt.bg/sat/" -y "livestream1" -o "bntworld.flv"

and here a few screenshots

Hasomaso,
This totally works !!! Thanks a lot !!!
Still puzzled though how did you figure these out ? These parameters don't quite match "rtmpsuck" output I got. There is some magic going on...
Where rtmpUrl(edge3), stream-name and secureToken came from ?
Do you think I have incorrectly used rtmpsuck since I had to redirect non-standard port 2020 ?
Did you use only rtmpsuck or had to spy on TCP packets with Wireshark or something ?
If you could point me to any links/manuals would be appreciated.
At any rate, THANK YOU !
