build x265 for Ryzen

[ghostshadow]

Hi, are there any options to enable when compiling x265 sources to optimize for Ryzen 5xxx CPUs.
Ditto for the Intel 13xxx series.
THANKS

[microchip8]

if using GCC, add -mtune=znver3
for Intel, add -mtune=alderlake

thanks, but i am using visual studio 2019

OK thanks.
Another question :
To compile x264 this time but with the libraries libswsale, libavformat, ffmpegsource and lsmash how do we do it?
I'm using msys64 on windows to compile the x264.
Thanks in advance

You might want to look at https://github.com/m-ab-s/media-autobuild_suite it does compile x264 and x265 with all those dependencies.

Thanks the auto script 'media-autobuild_suite.bat' works fine.
But if I want to make my build from a source that I download (git of x264 mod), I find myself in the same situation.

In the source folder of x264 I type this :

./configure --build=$MINGW_CHOST --host=$MINGW_CHOST --prefix=$LOCALDESTDIR --bindir=$LOCALDESTDIR/bin-video --enable-static --enable-pic --extra-cflags="-I/c/media-autobuild_suite-master/local64/include" --extra-ldflags=-L/c/media-autobuild_suite-master/local64/lib

But the result is not good, it does not integrate me libswsale, libavformat etc ..

./configure --build=$MINGW_CHOST --host=$MINGW_CHOST --prefix=$LOCALDESTDIR --bindir=$LOCALDESTDIR/bin-video --enable-static --enable-pic --extra-cflags="-I/c/media-autobuild_suite-master/local64/include" --extra-ldflags=-L/c/media-autobuild_suite-master/local64/lib
Unknown option --build=x86_64-w64-mingw32, ignored
platform: X86_64
byte order: little-endian
system: WINDOWS
cli: yes
libx264: internal
shared: no
static: yes
bashcompletion: no
asm: yes
interlaced: yes
avs: yes
lavf: no
ffms: no
mp4: no
gpl: yes
thread: win32
opencl: yes
filters: resize crop select_every
lto: no
debug: no
gprof: no
strip: no

bit depth: all
chroma format: all

thanks

Try with --enable-lavf

it's good I managed to make my codecs by modifying the script of media-autobuild_suite-master.
On the other hand, on my x265 codec where I integrated avisynth, I can't use my bat script that I had when I used avs2yuv64.exe

@echo off
echo Encoding movie
echo debut encodage %date% %time%
@echo on
cd /D "C:\Program Files\CreaVideo\proEncod"
start "" /b x265-x64-v3.5+20+10-aMod-gcc12.2.0 --pass 1 --bitrate 35303 --stats "D:\Log265\TestQP.stats" --output-depth 10 --profile main10 --no-slow-firstpass --level-idc 5.1 --high-tier --rd 5 --rskip 2 --sao --limit-sao --selective-sao 4 --cutree --qpstep 4 --ctu 64 --deblock -3:-3 --min-cu-size 8 --bframes 9 --b-adapt 2 --rc-lookahead 60 --lookahead-slices 1 --hist-scenecut --hist-threshold 0.03 --ref 5 --limit-refs 2 --merange 57 --subme 7 --rect --amp --max-merge 5 --aq-mode 4 --aq-strength 0.90 --tu-intra 4 --tu-inter 4 --limit-tu 4 --me 3 --hdr10 --hdr10-opt --master-display G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,0) --min-luma 0 --max-luma 1023 --max-cll 1000,638 --gop-lookahead 0 --weightp --weightb --repeat-headers --aud --hrd --qcomp 0.60 --rdoq-level 2 --qblur 0.6 --psy-rd 2.10 --psy-rdoq 1.35 --vbv-maxrate 160000 --vbv-bufsize 160000 --colorprim bt2020 --transfer smpte2084 --colormatrix bt2020nc --output NUL "C:\AVS265\TestQP.avs" - 2> "D:\Log265\TestQP.log"
echo fin encodage %date% %time%

exit

I have an error : x265 [warning]: extra unused command arguments given <->

Just wondering, what exactly does this do? Would this work on other x265 encoding platforms like Handbrake or Vidcoder, for instance?
Does this take advantage of more hardware options?

it optimizes code, where possible, for the specific CPU architecture. Most of the time, this results in slightly faster program compared to a generic compiled one.

yes, it does work with other programs. It's just an optimization.

Okay, good to know, thanks for the response. I have an AMD CPU, how do I know which version I'm using like 1,2 or 3?

Ryzen 1xxx is znver1
Ryzen 2xxx / 3xxx is znver2
Ryzen 5xxx is znver3

Or read the man page of GCC.

Hello, for me I won on alderlake on laptop 0.5 fps in x264 with avs denoise filter.( 6.15 fps)
For the ryzen3 I gain between 0.5 and 0.8 fps in x265 on pc. (5.2 fps)
to compile you have to put: -march=znver3 -mtune=znver3 to compile with all the zen3 architecture for example.
But in this case the codec will only work with ryzen 3.
If you put that -mtune=znver3 he compiler does not generate any code that cannot run on the default machine

i have ryzen 7900x, which version should i use? and what is the best website for it?

any cli command to use which increases performance?

-mtune=znver4

it is only present in GCC 13 and above

can you point me to the website page where i can download such version?

I can point you to the site of GCC but it only offers raw code. You'll have to compile it yourself. I do not know who offers Windows/MinGW binaries for GCC. There are some here on this forum
