www.channel4.com: Using Rtmpdump for downloading 4OD videos

WhynotAndy · #1 02-20-2010, 07:59 AM

Hello

I'm trying to use rtmpdump to save streams from 4OD (channel 4 UK) .
The video I'm trying is at

Code:

http://www.channel4.com/programmes/my-big-fat-gypsy-wedding/4od/player/3034485

URL snooper gives me rtmpe://ak.securestream.channel4.com/4oD/mp4:assets/CH4_08_02_16_48115001001003_001.mp4
and

Code:

http://www.channel4.com/static/programmes/asset/flash/swf/4odplayer-4.37.swf

When I use rtmpdump it gives me an error telling me to use --swfVfy
I've downloaded the 4odplayer-4.37.swf player and put it in the same folder as the rtmpdump but I don't really know what string to use for this or even if I needed to do this.

Any help on how to form the correct command for rtmpdump would be great .

Thanks

I'm also trying to record a stream at 4od via this method and failing miserably. Is it even possible with 4od?

You don't need to download the SWF file yourself.

I can't doublecheck this since I'm not in the UK and they're denying access based on IP addresses. But something like this ought to work:

Code:

rtmpdump -r rtmpe://ak.securestream.channel4.com/4oD/mp4:assets/CH4_08_02_16_48115001001003_001.mp4 -W http://www.channel4.com/static/programmes/asset/flash/swf/4odplayer-4.37.swf -a 4oD -y mp4:assets/CH4_08_02_16_48115001001003_001 -V -o output.mp4

Hi,

That command doesn't quite seem to do the trick - although it does get you quite some way there. The output is:

DEBUG: HandShake: Genuine Adobe Flash Media Server

Does that help in getting there?

Try adding -p and the URL of the web page.

you know what's funny? Using a windows XP machine, I used Any FLV Downloader and it worked great. no intricate commands or anything, it picked up the stream and you click the download button. Totally didn't work on my Windows 7 machine. Just thought I'd throw that out there.

Hello thanks for the answer
I had a go with the code you suggested and it didn't work

Download rtmpdump 2.2. Read the manual page. Read the error message you got. Post back again after you've done all that.

Without -a 4oD, this error vanishes but the stream still does not play. It says:

I've read the man page, but I still can't figure it out, would you mind explaining? I'm not even interested in the 4oD content, I just want to figure this out!

Thanks.
