Please test for speed and stability.

x264 736 gcc 4.2.3:

x264 736 gcc 3.4.6:
x264.736.gcc.3.4.6.exe (http://files.x264.nl/x264.736.gcc.3.4.6.exe)

Including system information may be useful aswell.


My own results, just some random settings:

Results after running the 4 .exe files for the 2th and 3rd time to prevent any caching speed difference:

Hmm, very interesting...
Think you can provide a small source sample so i can try to reproduce? source/avs file/possible avs filters.

I always used the same script and following settings : x264 --crf 22 -b 2 --thread-input --threads auto -output test.mkv test.avs :

Here the video file and script

[bob0r]

Thanks for the information.
But i see another crash report is in.

Guess we shall stick to gcc 3.4.6 forever! :)

Edit:
I can not reproduce, so it must be something with GCC 4.x? 4.2.x? I dont remember any 4.x version being stable ever.
