I recently had to setup a new streaming computer to stream content to youtube. I tested some recordings and streams and they all looked okay, but while reviewing the recording on youtube, there are some spots where the recording skips ahead 15-45 seconds. I'm using an i5-14500T, with 32gb of ram, dedicated 2gig business internet, wired ethernet to the desktop, and ingesting 1080p HDMI input from an avermedia live gamer ultra and using OBS to stream that capture to youtube. After running numerous tests and analyzing the recordings, I have determined that this only occurs when I have the intel QSV HEVC codec selected. Switching to H.264 prevents this from occuring. Is anyone aware of what may be causing that issue?

Use a faster Preset, like TU3 or TU4. Your internet connection is lame, bad cable, driver or something else. More dropped frames than encoding lag.

I was test streaming H265 with my UHD 770 the other day. Using these settings my encoder was 45% utilized. H264 is uses roughly half.

Is that a Dell? Your driver looks like it's stale, released in late 2023 from what I can find. An update is in order. If it is a Dell, check their support page. No Windows driver on the Intel CPU page.

This is the latest driver from Intel but I don't see your CPU on the support list.

If you see the below after you switch over, check for a NIC driver update too. These errors are generally caused by the driver (Default EEE settings).

There was (4) encoding sessions in that log. (2) of them had the WriteN errors, (1) with dropped frames, (1) failed.
The (2) streams with no WriteN errors were A-OK, no dropped frames.

Got video and network driver updated, also went into the ethernet settings and disabled EEE. I set my settings to match your previous post, and am attempting another stream.
Do you know how well RTMP streams handle packet inspection and SSL decryption? I'm wondering if I need to put this machine into a bypass rule as well.

Cool
Not really, never had any issues streaming. I run my own server & don't use a CDN

You're streaming to a CDN, Content Delivery Network. I don't do that.
