Question / Help Encoder overload (x264) CPU usage at 35% - why?

[BigYuckFou]

Hello fellow OBS members,

Can anyone help tell me why I would get the "encoder overload" while attempting this?
I use a 14 core Intel with hyper threading running at 4.7ghz all cores.Dang good PC. 32gig memory and a 2060 KO Ultra GPU.
I am using x264 CPU encode. Slow preset.

I do have set some optional x264 presets settings,
[x264 encoder: 'streaming_h264'] custom settings: subme=10 trellis=2 direct-pred=temporal me=umh bframes=2 ref=4 threads=22 level=4.2 aq-mode=2 rc_lookahead=60 b_adapt=2 me_range=24 analyse=all partitions=all

This PC should be able to do this I think. Any assistance will be greatly appreciated!

aq-mode needs to be off with a subme 10 dude, you're correct on trellis 2 but aq has got to die.meanwhile i also disagree on doing all partitions, unless you have some very specific use case you wont need it. do some experimentation by removing lower 4/4's etc. Level 4.2 is also a bit overkill as with the rest of it. I would just set in for medium or faster. Subme 10 is an order of magnitude slower then 9. I use 9 on a dedicated ryzen 1700 and that works fine. and that's 8 cores at slower clock speed. By setting slow preset you are demanding there will be nowhere near any unexpected peaks which is completely unrealistic. I can use slow preset but i dont see much benefit. But it's also on an optimized system, ie I configured it.

Ideally you should have things be the same value for video and also for audio bitrates.

Hey good budro, I sincerely appreciate the response. I just used the RCH1 anaylizer. and it says all is ok except I am using non standard preset settings.

why is it that the CPU Overloaded and dropped frames occurs when the CPU is at 35%? I too built this PC and have configured it for the sole purpose of ingest and encode of a stream I do not use this PC for anything else. I play on Xbox and encode with it.

I will disable aq mode now. thanks for the tip. Do yu happen to have the partitisons numbers string for OBs you think I should try?"

p8x8,b8x8,i8x8,i4x4

"

take a look at these logs and RCH1 analysts please.

I did as suggested.
aq-mode=0
removed partitions=all
dropped subme=9 (down from 10)

still getting encoder lag and dropped frames with 35% cpu usage. any ideas?

well this always annoys me, since it's free to get:
12:04:32.697: [CoreAudio encoder]: CoreAudio AAC encoder not installed on the system or couldn't be loaded
12:04:32.852: adding 42 milliseconds of audio buffering, total audio buffering is now 42 milliseconds (source: Mic/Aux)
42 ms audio latency out of the gate is quite high, but doable.

All of this is annoying to me, we got different resolutions and different fps/intervals. That's just awful. I would set everything to same, and if need be sell it to get something else to make everything the same. By having everything on the same you remove a factor of latency that is a nightmare to troublehshoot.

What the fakk is going on here with keyint 119? ? use something sane like 250, or per 2 seconds. If it is on auto, it just shows it cant make sense of it.

4.3% is incredibly high, it might as well said 100%. This is just going to keep pissing you and viewers off, and then look great, then look like shit.

At least some good news there.

You just have to get a hold of yourself and clean up settings to be within reason. Steal coreaac from the application support msi off the itunes app by extracting it using 7zip or such.

You should do a custom ffmpeg out instead and then post what it uses, alltho i dont know if it does post a log as i never used ffmpeg from obs, as i do it from a dedicated unit. You would have a much easier time understanding this crap if you simply just downloaded ffmpeg and tried to do some encoding with a raw video and then you can see what ffmpeg will do, based on that it will actually *TELL YOU* what parameters it sets.
It's easy peasy actually.

Now coffee time!

YW and Happy reading!!!!

edit: oh and btw, if u simply just trellis 0 too and it should help a bit. but u need to fix the other things too, encoding isnt the whole issue there.
