ERROR: RTMP_ReadPacket, failed to read RTMP packet header

[nostromo]

I'm trying to receive live stream video from a site of a regional TV company.
I run

rtmpdump -v -r rtmp://ntk-origin2.cdn.ngenix.net:1935/live/_definst_/9tv-orb_ -W http://kuban24.tv/bundles/frontend/js/flowplayer-3.2.5.swf -p http://kuban24.tv/tv/ -z

with -z option and I get ERROR: RTMP_ReadPacket, failed to read RTMP packet header.
What's wrong?

Your datas are wrong.Also your playpath is not complete.Try this below.

-v
-r "rtmp://ntk-live.cdn.ngenix.net/slive/_definst_/" 
-a "slive/_definst_/"
-W "http://kuban24.tv/bundles/frontend/js/flowplayer-3.2.5.swf" 
-y "mp4:9tv-orb?t=1412632809&h=wHR0kJM1683OpDp8ZLxV4Q=="
-o "out.flv"

Another error: Closing connection: NetStream.Play.StreamNotFound

Yes you need to refresh the playpath which is dynamic.Just reload the site to get the new session playpath.

-y "mp4:9tv-orb?t=1412635103&h=/p3er68fn+zbn9wbschbxg=="

This part below...

?t=1412635103&h=/p3er68fn+zbn9wbschbxg==

...before it was...

?t=1412632809&h=whr0kjm1683opdp8zlxv4q==

Thank a lot for your advice. It works. I add curl and grep subcommands on my Linux system for extract current dynamic part and it's successful:

rtmpdump -v -r "rtmp://ntk-live.cdn.ngenix.net/slive/_definst_/" -a "slive/_definst_/" -W "http://kuban24.tv/bundles/frontend/js/flowplayer-3.2.5.swf" -y "$(curl -s http://kuban24.tv/tv/ | grep -o "mp4:9tv-orb[^\"]*")"

Could you help me again with other site? I use the same way with dynamic part detection,

rtmpdump -v -r "rtmp://ua4.parom.tv:1935/stream/" -a "stream/" -W "http://ru.parom.tv/player.swf" -p "http://ru.parom.tv/ru/1tv" -y "$(curl -s http://ru.parom.tv/ru/1tv | grep -Po "file=\K[^\&]*")"

but I get the same error RTMP_ReadPacket, failed to read RTMP packet header. What's wrong?
P.S. Sorry for my bad English.

I already decompiled http://ru.parom.tv/player.swf via ffdec, but there's not SecureToken in it. Other ideas how can I get this stream? What's wrong? Why I get ERROR: RTMP_ReadPacket, failed to read RTMP packet header? Please help me.

It works well, but I say about another site (http://ru.parom.tv/ru/1tv) with the same error (my previous posts)

[hasomaso]

playpath line change every seconds that is the problem..!

rtmpdump -v -r "rtmp://ua4.parom.tv:1935/stream/" -a "stream/" -f "WIN 15,0,0,167" -W "http://ru.parom.tv/player.swf" -p "http://ru.parom.tv/ru/1tv" -y "stream237?87" -o "output.flv"

hasomaso,
It's intresting. When I watch network traffic via Wireshark I also see that the playpath (file) variable always changed, but it's always stream237?s=<big hex value (34 digits)>. You wrote -y "stream237?87". How you find it? Do you transform the big hex value after s= or do something else?
