x264 video encoding benchmark

[graysky]

I put together a self-contained x264 video encoding benchmark. Techarp kindly agreed to host the file and results at this URL.

Basically, you run the test encode and it will report back frames-per-second values for your machine @ it's clock/overclock level. You can run it at your stock settings and at your overclock settings to see how your machine compares to others in the database.

The database is small right now (as of 08-sep), but as you guys report in results, I will populate it. My goal is to have a representative set of data for many different chips and chipsets. Hopefully, we'll get some Penryn and Phenom data when they become available. Also, if anyone out here has some of the high end AMD chips, please contribute. Instructions and the file are at that url.

Also, please report your results here in this thread. I will keep the data at that url to keep things simple.

Thanks all.

linux version please.

@directhex - wish I could... I don't know how you'd get avisynth to run without WINE.

[aidanjt]

Subsitute avisynth with transcode or mencoder.

Should be easy enough. The command line to the H264 encoder is on the second page with the FAQ

@directhex - wish I could... I don't know how you'd get avisynth to run without WINE.

avisynth isn't necessary on linux - you can pipe raw output from a player into the x264 encoder. or in come cases, use a FIFO.

fr'example:

mkfifo pipeymcpipepipe.y4m
mplayer -vo yuv4mpeg:file=pipeymcpipepipe.y4m test-480p.mpg &
x264 -o outputty.264 pipeymcpipepipe.y4m

dilute to taste

okay, benchmark ported to linux. cleaning up.

cool man

see www.apebox.org/wordpress/linux/32 for linux benchmark

hm, seems mplayer is throttling to ~30fps. fiddling...

[directhex]

MUCH better. script above updated. will re-test at home this evening. until then, i'll do my work PC. and... who wants to hear how well a 148 core box does?

looks like the hand-optimized assembly code for i386/amd64 really makes a difference, especially to the frameserving by mplayer

you have a 148 core machine at work? that's insane.
