Problems with RTMPDumpHelper (password protected site?)

[julesh]

I'm trying to download videos from a password protected site (bobnational.net) using RTMPDumpHelper. I don't know if this is supported or not, but I figured that because its a proxy server any authentication information ought to be passed on, so if anything's going to work this should. But I get an error when the video starts to play:

Any suggestions how to get the video downloaded?

Hmm. Never mind, RTMPExplorer was able to get it working. No idea what it did differently...

Looks like I spoke too soon.

Any ideas why I'd be getting a(n apparently) corrupt output file from rtmpdump?

Edit:
Huh. Even *file* doesn't understand it...

admin@tmp ~/Desktop/rtmpdump/explore
$ file 000000.flv

Suspect it's missing its headers or something.

Suspect it's missing its headers or something.

Yes, that is right. For whatever reason, rtmpdump is not writing the first 13 bytes of the header. I'd have to investigate further to figure out why.

rtmpdump is writing this:



Should be this:



Once the 13 bytes are inserted, the video will play ok.

Thanks, fired up xvi32 and it works great!
