Encoder overloaded

[Borca]

Hi

I'm recording and streaming in YT handball games for our local club in Women 1st league in Slovenia. I'm using Lenovo Thinkpad T520 with Intel I5 1,6 GHz CPU, 8GB RAM, 64 bit WIN10 PRO 21H2. Graphic card is Intel UHD Grahics 620, and NVIDIA GeForce MX250.

This is the analysis of log file:

Analyzer | OBS

OBS (Open Broadcaster Software) is free and open source software for video recording and live streaming. Stream to Twitch, YouTube and many other providers or record your own videos with high quality H264 / AAC encoding.

When only recording - without streaming - it's working ok. But with streaming it is terrible. Video is lagging in both - recording on PC and streaming. Can somebody please advice if this laptop is suitable for such streaming and give some advice on setting. I'm a little lost with all possibilities in settings. The stream has to be 1920*1080. I have some scenes - before game (some comercial logos and some text), then one scene for player names and referees... And then for actual game with scoreboard (time, result). There is one for timeout - again some comercial logos for sponsors.

Last year I used HP ProBook 450 G4 with intel i5 2,5GHz with 8 GB RAM NVIDIA GeForce 930MX and Intel HD graphics 620 and it was ok. The old laptop's keyboard is not working so I'm trying to use new one.

I attached 3 different log files - I made some changes that didn't work. None of them are from actual game.

This is the link to actual game

Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.

Thank you for your help.

When indicating a CPU.. something like an I5 and MHz is not sufficient (as there are 10+ years of various iterations/models), so best to include actual model number which will tell us which generation of CPU. In your case, your log indicates i5-8265U CPU. The U meaning ultra-low power optimized for battery life, not the computationally demanding task of real-time video encoding.

When streaming, are you also recording? are you using same settings, or having computer do extra work with recording at higher resolution than streaming (which is what I do, but on a more powerful PC not subject to same thermal throttling as a laptop). And that CPU is 4, soon to be 5, generations old. Your PC is also having to work extra to process the video incoming at 60fps. To reduce computational demand on PC, testing by dropping camera to 30fps might help? And not sure if camera's audio at different sampling rate will cause an issue

Then general recommendations of hardware resource monitoring while testing to see how CPU,. GPU, Disk I/O etc are doing, and if nearing bottleneck. And be sure to learn how, on yoru specific system, to monitor for thermal throttling (BIOS reducing power/performance to avoid overheating).
I'd think you'd be able to use this system, but will require some optimization of both OS and OBS

Thanks. I tried with older laptop and it works just fine. I upgraded to OBS 28.0.3 (64 bit). Only warning I got was critical outdate plugin source copy, then because of Wi-Fi streaming. I even tested the stream, recording and viewing on YT on the same laptop - and it's working.
I'll try to change some settings on Lenovo T520 and test it, but I thing that will continue to work on HP.

I forgot to mention, that i'm recording and streaming at the same time. I can put OBS recorded video directly to handball federation.
If I use camera recorded video I have plenty to do with rendering - time consuming.
