How to detect bitrate?

axeld · 20th December 2001, 12:23

I spent over 5 hours searching the solution on internet.

my problem is "I can't detect if the divx was made in constant bitrate (3.11) or variable bitrate (sbc or mixed methods)"!

there is a tool to analyse (RDF analyzer), but it shows me only RDF of movie, not the bitrate. Bitrate indexer also didn't help me. It generates a text file but I don't know how to inteprete it.

maybe somebody know how to do it?

i'm sure it is possible. in the movie after header there are some bytes like 00wb or 01bc or something like this, I read it is video and audio interleaving, but did it say something about bitrate?
at the end of the movie are also such a bytes but much more.

why I need it so much?
I like to know if the movies I have in my collection was made in 3.11 or SBC or in mixed method (low+fast)

please help.
