Compiled vs Downloaded speed increase data point

[displacedtex]

I am running CentOS 5.2 64 bit on an AMD x2 5200+ (dual core 2.6 ghz processor) with 2 GB of 800Mhz RAM using my new GIGABYTE GA-MA78GPM-DS2H motherboard.

I am mostly transcoding directly from DVD to x264 to be played on my wife's Ipod touch and my computer using the Hi-rez preset:

Code: Select all

./HandBrakeCLI -i DVD -o ~/Movies/movie.mp4  -e x264 -b 1500 -E faac -B 160 -R 48 -f mp4 -I -w 640 -m -x level=30:bframes=0:cabac=0:ref=1:vbv-maxrate=1500:vbv-bufsize=2000:analyse=all:me=umh:subme=6:no-fast-pskip=1

So I got about 30 FPS using the pre-compiled download vs 35 FPS for the latest compiled SVN version.

Just a data point.

I am waiting for my new AMD Phenom 9550 quad core to come in. I am very interested to see how fast the quad core is at transcoding!!

Question for the linux gurus out there... will re-compiling under the new processor add any benefit? I don't think it will, but thought I would ask the experts...

Any other similar data points for the hi-rez preset?

Oops. Just discovered the "Misc->Benchmarks" section...

I'll post it over there...

Although I guess it is a little useful in the linux section, since involves compiled vs pre-compiled...

Well, you are likely not using the same svn rev. The latest precompiled dev snapshot is 1477 and depending on what rev you got when you said "latest compiled SVN version" there could and are numerous changes. Not the least of which is a much newer version of x264 which is more optimized.

So if your talking about speed just in respect to a precompiled downoad from the website vs. compiling from source yourself, you would want to compare against the same svn rev, otherwise your results are very skewed.

Good point.

For clarification, I am now using svn1568.

To be a valid comparison, I should have compiled 0.9.2.

Thanks!!

Yep. your results are very skewed if the precompiled binary you are referring to is 0.9.2 . 0.9.2 to current svn is quite a leap.
