I have been having a weird issue for the last few weeks. While I do not think it is MIMO causing it, I am hoping others may have experienced and solved it.
What is happening is, when I stream live, all of a sudden, the entire computer freezes. I have to press the power button and hard-reset the computer. This DOES NOT happen if I record, instead of going live.
This is also happening when I export a video out of Final Cut, using H.264… exporting ProRes does not cause the crash. It seems to be related to H.264 encoding.
Anyone else seen this? Any workarounds?
May I ask some details?
• Version of mimoLive?
• Hackintosh or Mac (which Mac, About this Mac, everything except the serial no.)
• Any error-reporting by macOS? (Please have a look to console.app)
• Any screen recording(s) inside of your document (window capturing)?
• Any RAM-optimizers or other optimizers installed?
• Is any backup software running the same time?
That would have been smart
iMac Pro 2017. 8-Core Xeon W, 32GB, Radeon Pro Vega 56 8GB
macOS Big Sur 11.2.3
Latest version of MIMO (been happening for a while - Currently 5.10)
No backups running.
I have gone as far as factory resetting the machine with a clean install… same issue in MIMO and FCP… again, ONLY seems to be when doing an H.264/5 Encode
• Does it work when you close mimoLive and when you switch off background rendering of FCP?
• Did you install any plugins for FCP?
• Did you do all of this? Resolve an issue in Final Cut Pro - Apple Support
• When you use 1-Click Video Converter im Mac App Store to test-convert a video to h264/5, does it also freeze?
BTW, 1-click-video-converter got several options h264 (mp4) / h264 (mov).
Background rendering on or off seems to make no difference. Tried with a clean fresh FCP (no plugins), same issue. Not sure what you mean about with MIMO Live closed.
I have done ALL those things on the support page, and a whole lot more, same result.
It seems I am not alone. Found a thread of others having the same issue, including exporting H.264 from Premiere. I have NOT seen this happen yet in Adobe Media Encoder, ScreenFlow. Haven’t used 1-click VC.
When h264 (mov) crashes and h264 (mp4) does work (or vice versa), then there could be a bug with the graphics drivers. You could switch on mimoLives debug mode to switch on/off the hardware encoder, to test if this helps (as a workaround):
Just type “Debug” at the help window. Activate the mode at the so called “Debug preferences”. Quit mimoLive and reopen it. You’l get a new menu called Debug.
I hope this helps to proceed with mimoLive. If there is realy a bug, please report it to Apple: https://feedbackassistant.apple.com
I was hoping there was a way to do exactly that, as I think that is the reason.
However, I hit ‘debug preferences’ but nothing happens, and I don’t see that debug menu
Did you restart mimoLive? (a simple close does not work: quit and open it again.)
Quit and opened it a few times. No debug menu
Another way: Open this menu, hold the “option”-key and select “debug preferences” from the menu.
Maybe I should have mentioned to click the found result.
Inside the Debug Preferences you’ll be able to activate the debug mode.
That seemed to do it! I have the prefs now
Fine. Now, enable the checkbox and restart mimoLive. (quit and open).
Afterwards, continue here:
Crashing During Live Streams - #6 by JoPhi
@Ray_Lane, please let me know if it worked for you.
Thanks. Doing a test stream now…
You’re welcome. This is now on CPU-load, but if it works, it’s a nice workaround.
It is still streaming… And re-affirming what I thought the problem might be, but had no idea how to disable
Sounds amazing! Don’t worry about it. I’d suggest to report this bug to Apple, so it will be solved some day. Hopefully. https://feedbackassistant.apple.com
Now I wonder if it is the Apple T2 encoder or from the graphics card?
You could switch on the hardware encoder again. Afterwards try it with https://boinx.com/connect/mimolive/versionhistory/5.10.1b3 - some T2-issues were solved. Do you use a USB audio-interface?
5.10.b3 is actually the one I have now that was still failing with the hardware on. I do use a Yamaha USB mixer interface with my RE20 mic, etc.
I did not know that. I thought you were using version 5.10.
I’m happy that the workaround works.
Ps: 5.10.1b3 or 5.10b3 ? :), @Ray_Lane ?
