Question / Help OBS Studio Video Crash

[SAngeli]

Hello,
This evening it was my first Live Stream ever with OBS Studio. I simply love this software.
Sadly, I had a major and urgent issue to solve. While streaming live the video crashed meaning I started seeing, in studio mode, on both screens/windows the entire video with all pixel or simial. So, I quit immediately OBS and run it again and did not have any issue till a bit later. When it happened again I closed and opened again OBS Studio and then never had this problem again. This made me very scared and had fear in using the software and PC becasue I was streaming live.
I will attach OBS log and the screenshot of what happened. Please note that while video was scrambled audio was still working. Can someone please help me out understanding where the problem comes from and how to fix it? Tomorrow I have another Live streaming and wish to avoid having the same issue.

This is my hardware:
PC
Processor : Intel Core I5-2400 (3.1GHz, 6MB)
Memory : 4096MB (2x2048) 1333MHz
Graphics Card : 1GB ATI Radeon HD 5450
OS: Windows 10 Home x64
SSD: Crucial MX200 250GB
Note: As this PC does not have any USB 3.0 I added a PCIe Atlantis Land USB 3.0 - 2 Port PCIe Card model P001-USB30-PCX
This card was installed and using Standard Microsoft drivers. I updated adapter driver with Renesas Elettronics released on 10/05/2012 ver 2.1.30.6 I found on the Internet.

Video Recorder
StarTech USB 3.0 Video Capture Device - HDMI / DVI / VGA / Component HD Video Recorder - 1080p 60fps
Product ID: USB3HDCAP


The second issue I had, probably because I do not have experience yet with OBS, is playing Desktop Audio.
I wanted to play a sound in the background of a still image and though using Desktop Audio. I do not know if I did right this way. The issue is that audio was a bit choppy and not smooth as the entire video being streamed live. Also I had some troubles between Line In/Mic and Desktop Audio. Sometimes I was listening to Line in/Mic while palying the music. What is that did wrong?

Many thanks for your help.

Hi,
I just wish to followup with results from my second Live Streaming for this case.
I was able to avoid having the "major and urgent issue" of video crashing. Three things I did and do not know which is the correct one (I suspect the second one) that solved my major issue:
1. I updated software version from preivous 16.6 to ver. 17.0
Software downloaded from OBS Project website
2. Installed AppleApplicationSupport.msi to solve "CoreAudio AAC encoder not installed on the system"
Software being extracted via 7-zip from QuickTime
3. Run OBS Studio 32bit rather than 64bit

I checked log file again hoping to have solved CoreAudio AAC but still persist the error messsage (see logs).

I suspect that the issue comes from OBS Studio 64 bit version because it is too strange that I did not have any issue today at all.

As for the second issue, the Desktop audio, I was able to solve it myself. I determined what I was doing wrong.
I am quite sad that I do not know how to acchieve two things for audio:
a. being able to hear the "real" audio level OBS Studio produces when managing with the slider audio settings in real time
b. in order to have full control on play/pause/stop for audio files I have to rely on Desktop Audio. This because if in the mean time I am playing something else (like watching live what I am streaming) I have an additional audio source that disturbs streaming.

Please let me know.
Thank you

It sounds like you were able to clear up most of it, so:

a. Audio monitoring is not yet available in OBS Studio. This is a planned feature, but the work required to implement it is quite extensive, so it may be a while before it's added. In the meantime, I suggest you just make small recordings with various levels, listen to it all back at once, and determine which are the best for your use case.
b. This is also something not quite possible in OBS Studio yet. You can pretty much only stop/restart media sources. I'm not sure what further controls for this are planned, so I can't comment on that.

Hello,
I am sorry to notify that the issue I have had with graphics happened again. So, it happened both with 32bit and 64bit OBS Studio software.
I asked StartTech support to see if they can determine the cause of this issue but they were unable to further assist me bucause I was unable to replicate the issue.
Here is their reply: "Unfortunately we are not experts on OBS as we do not directly support it. So we do not have the knowledge to use OBS Studio error logs to find out what is happening there. Perhaps OBS can help here as they may be able to explain the error. It sounds like our device is functioning correctly from what I can tell."

Please note that Video behaves this way while audio functioning properly.

Can someone, a developer perhaps, assist me here? I believe I provided all documentation needed to investigate.
I do not feel comfortable running a new Live Streaming fearing this will happen again.

Also, I wish to know if anyone can suggest a PCIe Capture Card with 2 HDMI input devices so that I can manage two handycams. Somethng that does not costo more than €150 and that is fully compatible with Win 10 x64 being FullHD.

Please let me know.
Thank you

We'll need logs more than screenshots :)

I already posted all log files.

 

[Fenrir]

From a session where you had the issue with your capture card? I didn't see any capture issues in the previous logs you had posted, but you posted multiple and it's hard to know which log is showing what issue.

Try these steps to get a clean log file that has the issue (assuming you can reliably replicate):

To make a clean log file, first restart OBS, then start your stream/recording for ~30 seconds (or however long it takes for the issue to happen) and stop it again. When you're done select Help > Log Files > Upload Current Log File. Copy the URL and paste it here.

Here are the logs of the third time it happened.
It happened 24 minuts after the show started. If you look at file "2017-01-06 10-45-22.txt" and file "2017-01-06 11-55-07.txt" you will notice that first file end at 11:55:02.956 while third file starts at 11:55:07.118

Also what does this "Shutting down" mean into second log file this?

11:53:08.713: User switched to scene 'Fine'
11:55:02.181: ==== Shutting down ==================================================

How is shutting down? does it mean that I am turning off/closing OBS Studio?

The way it happened is that as soon as I noticed that this missbehavior started I immediately closed OBS Studio and opened again and immediately started broadcasting live. It could have taken about 3/4 secs to do all this.

I hope this is sufficient as am not able to reproduce this at present time.

Thank you

Definitely some odd things in those logs... but not sure exactly what they mean. Looking into it, and I'll let you know what I can find.

Hi,
any updates, please? It would help a lot understanding what is happening.
Thanks
