Old x264 build

madeinlisboa

Why is DVDFab using an old x264 build? I don't even know what x264 core 142 build is.

I'm trying to pass some x264 options to the converter via the preset file, but apparently, they are not recognized.

they are:
true but I always read fast_pskip=1 in the mkv
2 but i read weightp=0
falsebut i read mbtree=0
2 but i read b_pyramid=0

Thank you

Anyone?

Not forgot but working for it.

x264 core 142 build is based on x264 0.142.xxxx version.

We did some changes with the x264_ABR_Fast.preset in the new Beta version V9165.

http://www.dvdfab.cn/mlink/download.php?g=DVDFAB9_BETA

true fast_pskip=0
2 weightp=2
false mbtree=1
normal b_pyramid=2

Hope this help you, thanks!

Thank you for your answer. I'm not aware of that version nomenclature. The official x264 binaries are here (http://download.videolan.org/pub/x264/binaries/win32/) and I don't see any relation. Please, can you explain better?

I've found an issue in the preset file. By default KeyframeInterval is set to 24, when it should be about 10x the frame rate (x264 settings), hence the default 250.

Wilson.Wang

such as, official x264 binaries, x264-r2453-ea0ca51.exe
run in cmd, use --version, you will get "x264 0.142.2453 ea0ca51", that is the 142 core mean.

KeyframeInterval value set explained in the wiki link, " Thus they can be used as seek points in a video."

Thanks.

I will keep using KeyframeInterval with 240 or 250 because its the suggested value.

I took a better look at what the core meant and noticed that several x264 versions have this core. Which specific release is embedded in DVDfab, being r2479 the latest? Thanks.
