[Guide] Two PC configuration without Capturecard
- Thread starter nrw2000
- Start date
Hi guys!
Thanks for the awesome tutorial, I managed to make it work with my poor skills on Windows thanks to this guide and Helping Squad videos :)
Somehow, I had to remove the $name from the transcode.bat to make it work, don't know if I misunderstood something or if it's different with windows from linux.
I have a question tho. If I want to stream in 720p, do I need to downscale it on OBS or the transcode is enough? I may have missed this information on the thread even if I read it tons of times.
Also, I found that my stream quality was a lot better with higher presets than lower ones, is it supposed to work like that? I know that a lower preset allows a lower bitrate, but I thought the quality was better for same bitrate+lower preset.
Thanks for your help and for the guide.

Yea $name only works inside the config file, nginx automatically replaces it with the necessary stuff. So in an external batch you have to replace those with your app and streamname :) But nice you got that covered!
If you dont save the original input size somewhere and just need 720p you could use the OBS downscale. But you can also check which looks best maybe. FFMpeg offer lanczos resize as well and some other filters.
Do you mean with higher preset = more cpu consuming? Its normally like that:
Ultrafast -> low quality, low cpu usage
superfast / veryfast -> low to med quality, low to medium cpu usage
faster -> fast -> medium -> slow -> medium to high quality with medium to high cpu usage
So using a "slower" preset than ultrafast should increase the quality in small steps.

Thanks for your answer.
For the cpu preset, on many tests using just one computer I had a worse quality lowering cpu preset :( I asked lot of ppl and everyone had the same thought that's why I was wondering ^^
Concerning this thread, I'm running into someone else problem:
"When I have successfully gotten it to twitch, their quality measure always says my keyframe setting is wrong, that CBR isn't on, and I observe the 1 second freeze every 5 seconds or so that I think some others have described in the thread."
It was working perfectly fine yesterday but now it starts freezing up every 5sec. 15K or 25K bitrate doesn't change anything, same for cpu preset on transcoding (I'm not cpu limited with medium in 1080p).
Any advice from ppl that managed to solve this problem?
Edit: after reseting everything, the issue comes from the bitrate. I can't use anything above 2k on transcoding otherwise it lags on stream. I have 5mbps and can handle 3/4k with OBS on single pc capture, I'm lost! :(

The first thing I would try is reducing the bit rate. Are you at 25000 k? Try something less.okuRaku said:
By the way, I streamed Battlefield 4 today to a local file (and uploaded it to YouTube later) using OBS without QSV on my 3570K. Bit rate in OBS was 25000k with a 7000k buffer. I couldn't tell I was streaming. I played later the same day without recording, and it felt the same.
Go into your BIOS and disable your integrated graphics. I know, you don't want to do that because you want to use QSV. Try it. Play Battlefield 4. You don't even have to stream. You'll notice that the game runs better. This was my result that was confirmed by someone I know doesn't stream/record. What goes away by disabling the integrated graphics is frequent micro-stuttering.
You don't need QuickSync on the nginx server :)
To anyone that would want to spend time making it work on Windows, DON'T. There are issues with ffmpeg and twitch, I couldn't make it work at all. It's really easy to do it with Linux if you follow nrw and Jack guides, even for a total beginner with Linux.

not neccessarily. what are the specs of your gaming rig?SKTLZ said:
it's not a matter of telling OBS to not encode, it has to encode since you're mixing multiple things in a scene. You have your game, an overlay image, and a facecam. That's the most basic mix of items, in order for all 3 of those things to be displayed for viewing (example: on twitch), they have to be encoded together. think of encoding like "live video rendering". This setup works in that your gaming rig using OBS is mixing them all together at a really high bitrate so it doens't have to compress everything down into a streamable bitrate (too high of bitrate and viewers wouldn't even be able to watch and of course it all depends on your upload limit). So this setup allows you to mix all 3 of your sources together at, for example, 25,000Kbps BUT since that bitrate is way to high to stream to your viewers, you send it to another PC to be transcoded down into a more reasonable bitrate (compressing it) and then that sends it to twitch or hitbox for viewing.
I have a 1 PC setup. it's an i5-4670k w/ GTX 760 and have no problem playing my games maxed out at 1080p AND streaming at 3,500Kbps 720p. I have not tried streaming 1080p yet.

Yes, it would help with performance unless you already have OBS set to the lowest CPU usage option.SKTLZ said:
I don't believe it's possible to pass media through OBS without encoding. If you did, you would lose all sound I think.
I have nearly an identical setup as the poster above me except I have a 3570K. There is slow down when streaming in CPU intensive games like BF4 and Guild Wars 2, but this two PC configuration makes it very manageable. I'm one of those players that plays BF4 on the lowest settings even though I have a GTX 760 because I want the 80-120 FPS that is achievable. I notice and care about slow down. But when I stream, I expect and accept the hit. I have not felt any slow down in other games by the way.

Thanks for the guide. I also had to use the ffmpeg static build to get it working. Works great.

I don't entirely understand, what do you benefit from this setup?

I guess the main idea is to not need a capturecard, while producing the same quality stream in the end and still offloading most cpu load to a second PC.
Lets say your main monitor uses 2560x1440 resolution, has 120fps and you want to record in 1080p30 for youtube, or even in its original resolution. A capturecard for that would probably cost you around 1000-3000$. I guess there can be different reasons :)

But surely you're still using a lot of the CPU streaming at 1080p on the gaming PC as well? I'm new to Nginx so some in-depth detail would be nice.Jack0r said:

TD;LR please. It would take me days to read this.Boildown said:

You want in-depth information, but you don't want to read? Surely that's the way to get there.
Please, it's only 8 pages, and most of it is short posts. If you are genuinely interested, that really should not be much of a problem to get through. How would this work if every time someone new came along we'd have to summarize every thread he is interested in?
