OBS Studio Crash Log URL​

theres no crash log

Expected Behavior​

I wanted it to record and work

Current Behavior​

Didnt work at all. Crashed without any log and didnt cause any cpu usage spikes or lag or freezing.

Steps to Reproduce​

1. Use these settings:
2. 
3. Have a Xeon E5 1650 V4 (i7 6850k) and an Rx 480 with 24 gigs of ram.
4. Use window capture.
5. Click record.
6. Watch it crash.

Anything else we should know?​

Reencoded a video with ffmpeg with the same settings as i used on obs (1080p) and it did that at 28fps but it would still crash on obs when i selected 10fps
ffmpeg -i test.mkv -c:v libsvtav1 -crf 22 -preset 9 -pix_fmt yuv420p10le -c:a copy testav1v1.mkv

Your Xeon is more than likely too weak for SVT. The quality sucks but try the fastest Preset (12) with mkv container & see if you can get any traction.

I checked my SVT Profiles, with a 12900k, I'm able to use Presets 8 & up. Anything lower & I get the same result as you.

1080p/60, Preset 10. Seems that the lower Presets may be mapped incorrectly, not sure for certain. BTW, dropping the frame-rate to 10 did nothing, it still shutdown on me using Preset 8 & 9.

oh yeah it doesnt crash on stuff above 9. this is an obs issue then i guess since both me and you are crashing and we have vastly different system specs. they closed down my github issue though so thats weird

I believe so, P8 & 9 used to work A-OK & things seem to have regressed since I installed v30.2.2. Who knows maybe the older version was the problem. Anyway, P10 produced a decent looking recording.

agreed but there isnt really an improvement on compression in bitrate lmfao. it goes up to like 18k on vlc and h265 on my gpu gets to 20k with settings that give better quality

 

[rockbottom]

Yep, gotta get it down to a lower preset or reduce quality. The video bit-rate on my recording was 19.3Mb/s, CQP, CQ=15.

Those presets may require AVX extensions that your CPU doesn't support. They seem to work fine on a Zen 4 system.

my cpu has avx1 and 2 lmao
people get the xeon v1s and v4s confused all the time

its like confusing a gtx 1080 with an rtx 4080

also dont think it requires avx512
my cpu is basically a locked i7 6850k and it launched at like 1050$ in 2016
