Question / Help Browser Sources Disappearing

[dWbstreet]

I have several browser sources linked to Streamlabs, YouTube Chat, etc. that function correctly; During the live stream all of them disappear. I have to manually open the source properties of each one and click ok for them to re-sync.

Please advise.

apologies all, was distracted, thought I had...

That log doesn´t show a streaming attempt.
Your scenes are very complex.

 

[dWbstreet]

I'll post another, I thought that was my last stream. Yes, they have multiple sources.

Thanks for your time!

1. 05:58:30.845: Couldn't find VLC installation, VLC video source disabled

As you use OBS 64 bits, you need VLC 64 bits.

It was in the first log too. Sorry.

 

[dWbstreet]

Thanks so much. Updated to 64 VLC. I'll follow up after this stream.

Did you notice at the bottom of the log the 30% missing render...Is that from lack of upload bandwidth?

 

[EBrito]

You were streaming 1280x720x60fps at 3500 kbps, preset veryfast, profile main.
Add audio bandwith: 160kbps
This makes a total of 3660 kbps upload.

You need minimum 4Mbps upload. Or, if you consider OBS using 80% of your bandwith, 4,5 MBps.
BUT you don´t have any drop due to network bandwith (it would be in the log)

So, better stream with 30fps.

 

[dWbstreet]

I'm not sure I follow you my friend.
I have 5mbps upload.
You said I don't have any drop due to network bandwidth...
Is my PC being overworked with the game playing and OBS running?

Is that why you say better stream with 30fps?

I would really prefer 60fps, could I lower the profile to preset ultrafast?

 

[EBrito]

So, 5mbps upload is enough for that bitrate.
That´s why you don´t have problems related to bandwith.
Yes, your PC is not capable of rendering all frames at 60 fps.
That´s why I suggest using only 30 fps.

If you want 60 fps, try first Superfast Ultrafast will give worse quality.
Also try with profile High.

Change one of this at a time, and observe log and streaming quality.
Then change both

Decide your best

Thanks so much!
I guess I need to get a second Streaming PC/Gaming PC.
Good to know!
Kind regards!!

My case: (Core2Quad Q6600 and GTX750TI): WORSE CPU than yours, very similar graphics card.
- VIDEO settings rescale to 1280x720x30 fps Lanczos https://gyazo.com/71bed7ef37a62c40131eed1a636dc471 (ESP)
https://gyazo.com/9ec70ea3449399112cc737f945351d23 (ENG)
- OUTPUT settings NVENC NO RESCALING, profile high, lowlatency high quality https://gyazo.com/58b7a27753b843f4a525cc8b7d4e4640 (ESP)
https://gyazo.com/a2036bbc9905ec7e72853bf3e347178d (ENG)

I USE NVENC, NOT x264.

A quick test with these settings: https://www.twitch.tv/jlbgamer007/v/103002091
Same video in Youtube: https://www.youtube.com/watch?v=H3kJLHZOJg8

(Note: dark colors maybe produced by choosing YUV 709 and color full. Back to 601 and partial (previous test were not so dark -ADVANCED settings-) Previous test: https://www.youtube.com/watch?v=cW_wtT-kxH8
YUV full: https://gyazo.com/1c7c8815d0d6126872bfd52d302ab5e8
YUV partial: https://gyazo.com/9fe315b23684e3cce6e665c4ab0b551b

This should work fine for you.
Better quality: rise bitrate to 3500 (not tested at 60 FPS)

 

[dWbstreet]

Thank you for sharing your setup!

Will the game suffer using the GPU to encode in OBS?

 

[EBrito]

CSGO: in my case, I play the same.
Sniper Elite 3: maybe I should downgrade anisotropic from 8x to 4x, but I do not feel it necessary.

 

[dWbstreet]

The last log I shared I just sent the feed direct to YouTube. Normally I send it to a rtmp (nginx) that pushes the stream to Twitch and YouTube. Does the bitrate in effect, double, in this case (meaning pushes 3660 to YouTube and 3660 to Twitch)?

 

[EBrito]

You send to a site that resends stream to Youtube and Twitch.
So, you don´t double bandwith.

NGingx needs double bandwith, not your PC.

Is the same scenary if you stream to Restream.io and then use their service to stream to Twitch, Youtube,......
You use "1" bandwith and they use "n".

 

[dWbstreet]

I'm not sure we are on the same page. I have a windows nginx server on my pc with an rtmp module. I send the stream there locally; It in turn uses a push command to send the stream to YouTube and Twitch.

So in that case I would I be going over my 5mbps upload connection?

 

[EBrito]

So, your PC makes double effort.
Yes, you will send double bandwith, more than you can.

Use Restream.io https://restream.io/

 

[dWbstreet]

Understood. Thanks again for all your time.

May I ask one further question: should I enable Hyperthreading?

 

[EBrito]

YES. You have to UNPARK all cores to get the maximum performance
