Nope. VideoLAN, which is also hosting x264, switched to git recently...

* Bssd is slower than unpatched (applies only with direct=auto). * Different video content for fprofile. Yes, I have said that the content doesn't matter much, but that doesn't mean I'd discount the possibility of .05 fps. (Well, maybe I would. .05 out of what, .2? Speed differences are meaningless. Please don't ever post one again. The meaningful measure is speed ratio, preferably accompanied by the standard deviation of N trials. The base fps that the ratio is relative to (or the amount of the difference, interderivable) is optional and is the least important datum.) * Different compiler. No, I do not have faith in newer gcc being consistently faster than old versions. (Consider that in a program as small as x264, even a single pessimized instruction in the wrong place could have a significant effect on total speed.) |

@MythCreator
Doom9 forum shortens URLs, so copying plain text isn't going to work. Here to make it easy for you: http://x264.nl/x264.modified.txt Also note the updated x264_2pass_vbv.7.diff patch. grab it from the collected patches dir, apply like this: patch -p1 < x264_patches/x264_2pass_vbv.7.diff |

@clsid: If you still read this thread, can you provide an install of MinGW with GCC 3.4.6 please?
@everybody: What's the difference between fprofiled and "normal" builds?

Well, the modified.final build of Mythcreator's is a fraction fractionally (...?!) slower than that of Bobor's modified 798. On a test I just did its was 99.998 percent (rounded up!) the performance of Bobor's modified build.
I'm just curious, if Mythcreator is willing to give it a try, purely as an experimental build whether he could try making a build with GCC 4.4.0. It is very much in testing stage, but snapshots can be downloaded by mirror sites. They're updated weekly according to the gcc site. One such site is: http://gcc-ca.internet.bs/snapshots/ (of course then select the latest 4.4 folder at the bottom of the list) Course could always build your own latest 4.4.0 snapshot from the GCC SVN svn://gcc.gnu.org/svn/gcc/trunk http://gcc.gnu.org/svn/gcc/trunk ^^ view contents I realise you probably know all this already, I listed it in case anyone was wondering GCC 4.4.0 supposedly has many optimisations that may finally allow it to be faster than GCC 3.4.6. Would be interesting to see anyway! Last edited by burfadel; 28th March 2008 at 19:24. |
