[rtmpdump] ERROR: RTMP_ReadPacket, failed to read RTMP packet header

[Alex Bennee]

Hi,

I'm trying to use rtmpsuck to dump the stream from the following page:

http://news.bbc.co.uk/1/hi/england/cambridgeshire/8398756.stm

I'm using the iptables -J REDIRECT method which seems to capture a packet
or two but rtmpsuck then fails with the message:

Although the video keeps playing in the web browser.

Looking at the dump from debug mode I saw an rtmp stream go past:

But it doesn't seem to contain a URL to any particular piece of media.
Could it be
being passed some other way? I can send a dump of the log if anyway needs it.

Regards,
