Bug Report Live stream video becomes choppy & laggy AFTER processing ended

[Ala13_Kokakolo]

I have read about the same issue in different posts but noone explain exactly the exact problem so I will try to explain what is happening in my case so if anyother user has the same problem can add their views to this post.

1. This problem started AFTER 4 November and I have not change anything in the way I was broadcasting or uploading videos.
2. I use OBS to stream directly to my channel in youtube. The format is 1080 at 30fps.
3. I use not to record a copy of the live broadcast on my HD but today I have started doing it. The video on my hd result all right.
4. While broadcasting, the broadcast is fine, interaction in the chat is fine and no problem is reported at all.
5. Once the broadcast is finish, the video starts to being processed. The length seems all right in the description but once I access the video (still while being processed) as soon as I start watching it the time counter gets shortened slightly (in summary, the video is shorter than what is shown on the info)
6. Still while being processed, the video seems fine but there are some minutes missing at the beginning.
7. Once the video finish being processed the lenght becomes halved (aprox) and is then when both video and image gets choppy.
8. This is a test I did that shows the problem:

I hope you fix this problem soon or at least give us some indication of what is wrong.

Hi! Please post a log from a session where this problem occurs.

If it always worked fine before, and you haven't changed anything (you haven't changed settings, updated OBS, installed other software, changed hardware, updated drivers, etc.), then I'd rather suspect your ISP or YouTube of changing something, perhaps unintentionally.

This is a file from another video but which was made with the same config and had the same problem,

 

[RytoEX]

From your log:

19:40:08.772: Output 'simple_stream': Number of lagged frames due to rendering lag/stalls: 2805 (63.8%)
[...]
19:40:08.775: Output 'simple_file_output': Number of lagged frames due to rendering lag/stalls: 2797 (63.8%)

Your computer can't keep up with its rendering tasks, so this isn't a bandwidth/streaming problem, and I don't see how your live broadcast would be fine with this amount of render lag. I've checked some of your other videos, and they also occasionally have skips and stuttering, but not this bad. Assuming nothing else has changed, have you checked your CPU/GPU temps to make sure that they're still in acceptable ranges?

If they are, then have you installed any new software that is running in the background or software that could interfere with OBS? Is your E drive healthy?


That said...

2. I use OBS to stream directly to my channel in youtube. The format is 1080 at 30fps.

Your settings show 60FPS. If you intend to record at 30FPS, you should change that setting as it will cause less resource usage and strain (Settings > Video).

 

[Ala13_Kokakolo]

When I did the first video it was at 30 fps. I just changed it to 60 to test. My computer has a 4770Oc at 4.2 and 8 RAM, it should go fine.

I have just installed OBS in a different computer at home running a ATI7970 (with a Phennon II) and I had the same result problem exactly. It does not matter with format I choose, wich computer or setting. I always have the same problem.

This is the video: https://www.youtube.com/watch?v=2WxlAMxXOdA.

I just uploaded the video, still in processing. Wait until it finish to see what happens.

It seems to me is a youtube problem (I have just contacted them). When I use Shadowplay to do the streaming, It went fine and also the upload. As is said before while broadcasting everithing is fine. What I mean is the problem only happens once the video finish the processing, up to that moment everithing goes fine.

This is the log:

It has finished and it is choppy again!! Another computer, same exact problem.

 

[RytoEX]

To me, it looked choppy when I checked it when you first posted it, not just later.

The thing is, if you didn't change any OBS settings and you didn't update OBS, and it suddenly stopped working, then it's hard for me to suspect OBS is the actual problem here. Your logs indicate local issues (rendering lag), not streaming issues (insufficient bandwidth). Try recording instead of streaming, and post those logs. If you still have rendering lag, then it's definitely not YouTube.

Shadowplay is a completely different program with completely different features and purposes, so it can not really be compared evenly to OBS for resource usage.

no, like the logs proof. Why ask here and than ignore the right answer?

 

[Ala13_Kokakolo]

no, like the logs proof. Why ask here and than ignore the right answer?

Because I had other logs with no problems but the same result. Because the system was working fine until two days ago, bacause i tested with less resolution and I had the same result and because I have installed the OBS in a different system and had the same result.

 

[Ala13_Kokakolo]

I did not install any software, temps are all right, I scale down size of otput and tryed less resolution and bandwich... always the same result.

 

[TryHD]

The downscaled video which you did delete out of the thread was fine and expecting that 1080p at 60 fps at encoder setting faster will work with your CPU is just stupid. Are you trying to troll here or what do you want to proof here?

Maybe you didn't know but the preview window of obs is not how the stream looks.

@TryHD
No need to get confrontational here. Let's be civil, please.


@Ala13_Kokakolo
Please try to record, as I previously requested. I'm fairly certain this is not a streaming problem, but I need you to test to confirm that. If it is a bizarre streaming problem that manifests in frame skips rather than frame drops, then my first guess would be that it's local to computers on your network or on your ISP, given that it happens on different computers. However, I need you to test what I'm asking for us to confirm the actual issue that's occurring.

Just to confirm some details... Are both machines overclocked, or just one? Have you tested on just two computers, or more than two? Have all the computers been on the same network/ISP?

 

[Ala13_Kokakolo]

Sorry TryHD I deleted THAT video but just because I was about to post another one NOT scaled but WORKING fine.. why everyone think bad about me!!!

I think I found the issue... After many testing the problem I think was the aero. Once disabled everything works as before the problem started. It is weird because I do not remember chaging that... anyway:

The video working fine: https://www.youtube.com/edit?o=U&video_id=IQ-zEt_yJpU

 

[Ala13_Kokakolo]

If you need further testing or more information please I would love to do more testings... but just if TryHD ask me nicely...:)

 

[Ala13_Kokakolo]

Maybe you didn't know but the preview window of obs is not how the stream looks.

I do have a second monitor and I usually check the streaming at the same time. I do know how the streaming looks like. Now that I was able to broadcast and process without a problem at 1080 and 30 fps, I go to bed. Tomorrow I will do more testing with 1080 and 60fps. I use the OBS to broadcast plane simulators tutotials, a bit of lag is not a biggy but a good quality image is a must. I am happy with 30 fps, but I want to test how much mi rig can take.

Thank you both for your help.

Ahhh, yes. I'd missed that. If I recall correctly, on Windows 7, having Aero enabled while a monitor/display capture source is running will absolutely kill performance. It would probably be fine even with Aero enabled if your Scene Collection only had a Game Capture source as long as there are no monitor/display capture sources in it. In fact, I think that having Aero enabled actually improves Window Capture performance.

Glad it's working now!
