Stream corrupt error and then rtmpdump goes nuts!

[Neill Mitchell]

OP here :)

Okay, dusted off my C knowledge and made sense of what rtmpdump is 
doing. The reason it only goes bang right at the start is because it is 
doing a bit of extra sanity and set up processing on the initial packets 
at that stage. This is enough time to tip it over the edge and overflow 
the buffer.

My original tweak of changing the buffer size from 64 x 1024 bytes to  
512 x 1024 bytes does not work well because it doesn't matter how many 
1K buffers you have, the 1K itself is not enough. So I've now modified 
it to 64 x 2048 and it is now seems reliable. I've also had to mod all 
the percentage calculations though to take into account the doubling of 
the buffer length. The downloads are all fine.

Cheers
Neill.
