x264 VBV -- Progressive download and Streaming

[floz23]

Hi everyone,

I've been a longtime user of megui and x264, and I have to admit that the work that everyone has put into it is quite amazing! From the programmers to the support staff on all levels, thanks!

But, I have a question that I've only been able to get partial answers to, and nothing totally conclusive. On the issue of VBV and progressive http streaming, and real "rtsp:" streaming.

I'm basically trying to figure out how to set the VBV settings to restrict the maximum bitrate of my .mp4 files. In the case of JWPlayer, i can set, for instance, a 3 second buffer. Should I set the vbv-bufsize to match that 3 seconds worth of buffer?

I understand that VBV is generally used for specific hardware requirements, but what about in the cases of progressive and rstp streaming?

Thanks,
-Adam
