My favorite OBS feature is that you can bring in transparent browser windows all over the place. As such, I have my work conferencing set up so my time appears in the upper-right corner. I’m on the east coast and everyone I work with is on the west coast. It’s a nice way to remind them of my current time. (It also passive aggressively animated to purple with a moon when its “after hours,” a/k/a 5pm for me.) I also ha…

OBS can alter a zoom or slack stream?

Doesn’t alter the existing stream. OBS creates new virtual camera that it outputs from your mix of input sources. You then tell zoom to use the OBS virtual camera as its source.

I've embedded a browser window in an OBS stream on my mac, and it just about ground my computer to a halt; the CPU was pegged at 100%, and using it with Zoom basically meant not using anything else. Is it just me?

I used to run a daily show off a tricked out MacBook Pro, and it was really problematic (e.g. 30 second delays on live streams). Moved to PC with a good processor and video card, and now it just sips the processor at ~12% with near-live performance. If you use OBS for live streaming, I strongly recommend you move off of Mac, especially if you do anything beyond the most basic operations.

There is a lot that you can do to optimize OBS streams before you may need to jump to Windows, however :)

Yeah; I'm not a streamer either, but it took me all of an hour to go from "what's OBS?" to enabling use of my iPhone as the video camera for Zoom calls. Haven't had time yet to do anything interesting with OBS "scenes", but it looks similarly, surprisingly straightforward. A+!

Which software did you use on the iPhone side to get this to work?

You can display RTMP streams in OBS. I don't have an iPhone, but once helped a friend get a GoPro working with OBS this way using its wireless streaming. Just plugging it in didn't work, it wouldn't just be a USB webcam. So, anything that'll let you stream with RTMP will probably work, and then you just have to input the URL on the OBS side.

* Added Undo/Redo [Programatic/Jim] Wooooh! That's going to turn so many instances of "Oh I've just deleted 30 minutes of filter tuning" into "whoopsy, undo" also: * "(Windows only) Added support for NVIDIA Noise Removal in the Noise Suppression filter" Nice! I wonder how that compares to the old RNNoise option...

From my experience the NVIDIA filter is miles better both in detecting noise as well as suppressing just the noise but has significantly more latency and will incur a decent perf hit on the GPU (~10% FPS or so if the GPU is the bottleneck). These days if it's live is use RNNoise and if it's for a recording I use Nvidia's filter.

Interesting. I have a PC just for streaming (I encode with CPU as well) with a[n] nvidia card, so I'm not concerned about GPU usage. I'll give it a go.

Slight tangent: Is it best to say "An nvidia card" or "A nvidia card"? 'An' sounds better, but 'a' is right according to my 4th grade english lessons. I think 'an' sounds better because you're really saying "(e)nvidia". I don't know if the "an before a vowel led word" rule applies to the pronounced or the written word...

I realized you could do that a few months back and finally built a little HTML/CSS/JS-based 'TODO' list so people could more easily follow along with my progress completing a set of tasks during live streams: https://www.jeffgeerling.com/blog/2021/obs-task-list-overlay...

It was trivially easy to get it formatted properly without me having to know anything about the GUI programming language OBS uses. Definitely an enlightening moment when I realized you can overlay anything with HTML!

So I've had the reverse issue. With hardware encoding on and external monitors plugged into my intel macbook, everything would overheat and I would get kernel throttling of everything. The external monitors cause the GPU to draw more power, but I'm not sure why that combined with hardware encoding in OBS caused issues. When I switched to software encoding the cpu was a bit higher but everything was fine. Apparently t…

I’ve had the same issue, it’s critical to get fans to cool your MacBook pro since they are not capable of cooling themselves under load, especially i7 or i9. I have cabinet fans under mine and it works great, just don’t ask me to use a MacBook Pro as a laptop.

And if not fans, I actually just elevated my MacBook Pro on a cooling laptop stand (with no ventilation) and that was enough to keep it cool for hours-long streaming.

Any idea when it’s coming? I know no one likes that question, but... well, I have an M1 Air, and I’d love to stream some coding sessions or tutorials. So arm64 support would be tasty. Is there some way we could help with the arm64 patching?

My smoothbrained take is that it'll be a little bit, since optimizing it for ARM is going to take a little effort. Like GP said, it's really about the encoders slowly being updated to better support the hardware.

There’s still also the lack of Metal support - OBS still uses OpenGL to composite everything together, and Metal should be more highly optimised on newer macOS versions and the new chips than the long-deprecated (on Mac) OpenGL.

Somebody actually did write a Metal renderer and contributed it in a pull request a few years ago. The comments were like “Oh, why did you do this? OpenGL is fine” from the lead developer. The backend just didn’t get merged (I think the developer who contributed it didn’t have great English so struggled to explain why they’d want it, and nobody who commented really seemed to know much about the Mac platform… the code looked fine though).

So that renderer was never merged, and then about six months later OpenGL was deprecated on macOS. The contributed backend is probably quite out of date with changes to OBS’s APIs etc. now.

It’s a shame, there just don’t seem to be many developers contributing to OBS that care at all about Mac as a platform, so I wouldn’t hold my breath if I was you for them doing much “optimising for ARM”.

OBS and VLC have made everyones lives better. And they have been doing it for a long time now.

There should be a global fund, funded by tax payers, globally managed, like the UN, that helps developers who develop software that is used in every nook and corner of earth. A strong incentive like that, and we could see a revolution in open source software.

Why is OBS so slow on Mac? Is there a hardware issue here, or is it a software issue with OBS?

It’s fantastic, but the speed difference on Windows is so much better.

As part of a school project this past year, my son had to do a historical video report. Together, we hacked together a set of 17th century evening news overlay graphics complete with scrolling headline ticker. OBS was great.
