Re: How to use iView (ABC Australia) downloaders

Bingo! Thanks, Anywho, that was it! It turned out that a weird set of unrelated changes to my LAN configuration triggered a router firewall fail. RTMP traffic was relying on the side effects of another rule for outbound Skype traffic and I foolishly hadn't checked the firewall log thinking this couldn't be the issue as it hadn't changed; I was focused on the IDS side, which had given issues in the past.

By default, rtmpdump will use port 1935 because that is the specification. I'm not too sure, but I think rtmpdump will fall back to port 80 or else port 443 if it cannot get access to 1935 (will that's what should happen IIRC).

However, I might just ask for confirmation on the RTMPdump mailing list that RTMPdump does actually fall back to other than port 1935 if it's not available.
Yes, I'd discovered this use of port 80 by sniffing traffic from the iView flash client which was still working fine. That's where I got the idea to change to "-c 80". However, to save you the trouble with the RTMPdump folks, I can say in my experience that RTMPdump doesn't fall back (at least in version 2.3). It would be a nice feature, though; if you have any chops with those folks, it'd be great if you'd ask them.

OK, sorry, this was a misunderstanding; I'd assumed since my ISP says it's unmetered and they can't unmeter Akamai sources (unlike iiNet) they'd always point me at Hostworks. I'd noticed people complaining on the ABC forums about a lack of fail-over from unmetered to metered sources when the ABC was having load issues with the unmetered side. However, it's probably due to gxdata being with iiNet; they'd have the fail-over option with unmetered Akamai.

I guess if that's true, none of the downloaders will fail-over for me, if they all refer only to the directions in the HOST field and don't second guess it.

Thanks again for the assist and detailed explanations!
