RV10 encoding speed

Hi, Steve,

We have come to a point that we need to know more exactly
what is the encoding performance of RV10. We checked the
only available Rv10 codec review .pdf file from Helix
community/Real website, there is a brief mentioning of its
speed, but not quite exact (there is actually a conflicting
and confusing info there with footnote) to let us decide
what machine we can properly choose for our encoding task.
Basically, are there any more thorough or exact doc that can
be shared in Helix community that gives:

What is the encoding speed or performance for encoding a
target of CIF 352x288 25fps  256kbps on a  P4  Dual
3.0GHz machine or whatever physical machine it could be
targeted for a standard test sequence, like, Aikyo, or
Foreman? The encoding speed can be measured by how many
actual frames RV10 can encode per second?  or How many mips
it takes for encoding a frame averagely?

Many thanks,

Frank,

I recommend you do a file to file encode of an input clip of
a fixed 
duration and your resulting duration will tell you how many
fps were 
processed.  I fully expect the result to be < actual clip
duration.  
That is, given that frame size and bit rate, encoding should
easily be 
faster than realtime on the box you specified.

The encoder also has several complexity levels that can vary
the
encoding speed up to 3-5X for real time adaptation on slower
systems.

For the system mentioned, the file reading overhead is going
to be large
part of the time it takes to encode an uncompressed test
sequence.

On my dual core 2 at 2.4 GHz, I get from 5 to 19 ms per
frame for
Foreman CIF, depending on chosen complexity, and from 2.5 to
14 ms per
frame for Akiyo, not counting file reading overhead.
