"Ghost time" issue with live webcast generated rtmp dumps

[mehphishtopheles]

I have been trying to rip live streaming webcast concert videos occasionally offered by a band I like. rtmpdump will run, but there are playback issues with the output files. First, here is what the server is sending me:

Here's what seems to be the issue: The webcast might start at let's say 8pm. The link to connect doesn't go live for a few mins and I am first able to connect at 8:05pm. The output files seem to think there is an extra 5 mins of video (hence my subject line of "ghost video") because the server is giving a static start time that is different from the actual time the video rip begins.

It causes all sorts of weird anomalies with various players/editors. Everything from not being playable, to being way out of sync, frozen image but working audio, etc.

I have tried using tools to fix this. FLVMDI, Replay Media Catcher's Fix FLV utility, and GetFLV's fix flv feature. I have yet to find a solution.

Can anyone help? Thank you in advance!

PS: I can upload an example .flv file upon request if that would be helpful.

PSS: I am using rtmpdumphelper in order to generate the command parameters.
