__mharrison__•1mo ago
Sadly, it breaks my scene with a PIP camera with a mask...
snvzz•1mo ago
That is actually sad. It is such basic scene.

I hope the next version actually works in some facility.

keyle•1mo ago
An obvious regression, you hope they'll get it fixed soon.
ChrisMarshallNY•1mo ago
Well, to be fair, they say it's an "experimental" version, so they would probably appreciate a bug report.
Warchamp7•1mo ago
Please submit a GitHub issue with some details on your setup!
29athrowaway•1mo ago
If you are

- recording your screen but not streaming

- you are not customizing what goes into your screen

Then use something else. GPU screen recorder has a lower overhead and produces much smoother recordings: https://git.dec05eba.com/gpu-screen-recorder/about/

aizk•1mo ago
Looks neat but seems like a complete hassle to get up and running and maintain, unless if your goal is to learn how screen recorders work.
gooberman•1mo ago
What? The link says that you can install it from flathub (https://flathub.org/en/apps/com.dec05eba.gpu_screen_recorder) so you just have to click install and then record. Since its in flathub its also available in many distros "app store"
beanjuiceII•1mo ago
i already have snaps why do i need this flat thing?
gooberman•1mo ago
You dont need it, it's just one way to install it. You can just download the appimage and use that as well. The point was to say that @aizk comment was ridiculous
aizk•1mo ago
Not gonna lie - I read this line

> If you are running another distro then you can run sudo ./install.sh, but you need to manually install the dependencies, as described below.

And then I just skimmed the rest, because I assumed it would be about manual dependency installation which I am not interested in.

Odd that the easiest installation method listed on line 3 was not the first line in the installation text, that's not a great DX.

Also - I'm on MacOS, and the OBS blog updated I shared was for MacOS.

29athrowaway•1mo ago
I was using an AppImage

OBS is great, it was my go to recording tool. But my videos were choppy until I started using GPU screen recorder.

jasonlotito•1mo ago
Why not just use quicktime?

Edit: I think you might have skipped reading the post. It's about OBS on MacOS. Where quicktime exists. Your suggestion seems geared toward Linux.

minimaxir•1mo ago
QuickTime cannot record system audio output without shenanigans.
jasonlotito•1mo ago
Yep, if you want to do something more than screen recording, just screen recording won't work. Nor will the OP's comment.
purple-dragon•1mo ago
The linked post is about a new Metal-based renderer for OBS Studio on MacOS. The software you linked is for Linux.
zamadatix•1mo ago
I think the point extends well beyond the specific app/OS example though, even though the article talks to macOS exclusively. For macOS and Windows there are built in tools which offer direct recording functionality. To trigger on macOS Command+Shift+5 (or launch it via QuickTime as jasonlotito noted), on Windows Win+Shift+S. Both of these utilize the same OS APIs OBS Studio uses to get the screen content, but they skip the step of needing a renderer at all.
spike021•1mo ago
I've had a lot of issues using the QuickTime screen recorder, especially when it comes to recording from an iOS simulator for app/game development and needing to produce preview videos.
GSimon•1mo ago
You need to install a 3rd party software Blackhole to even get desktop audio for screen recording with QuickTime. After about an hour of troubleshooting settings I gave up and used OBS, esp since I was in a public space at the time and the Blackhole config disabled my headphones and for a moment you could hear a loud YouTube tutorial playing through my Mac speakers. Also the shortcut to stop screen recording on QuickTime sucks, it’s like CMD+CTRL+ESC and you need to have it memorized because there’s no “Stop Recording” button option
ramses0•1mo ago
It shows up in the notification area bar (top) as an ambiguous circle with a square in it.
lelandfe•1mo ago
> get desktop audio for screen recording with QuickTime

A famously missing macOS feature. Loopback is yonder: https://rogueamoeba.com/loopback/

> the shortcut to stop screen recording on QuickTime sucks, it’s like CMD+CTRL+ESC

I just stop it from the menu bar, then on the resultant video press Cmd-T (trim) to lop off that footage.

koakuma-chan•1mo ago
NVIDIA has a "lower overhead" screen recorder, no? It's alt + f9 or something. AFAIK It's supposed to be optimized, because they own the stack and all. It's probably only on Windows though.
ycombinete•1mo ago
If all you need is screen recording, as per your parent, and you're on windows the default screenshot tool (Win + Shift + S) does screen recording.
stavros•1mo ago
This is great, thanks!
mcny•1mo ago
Does anyone know if AMD 8845HS with 780M graphics (running fedora) can into this? Ideally very low system resources used, I only have 16GB RAM, also ideally very little storage space used, one or two frames per second is enough, ideally should compress even more if nothing has changed in the screen for a while, also ideally should create a new file every eight hours or so.
gooberman•1mo ago
It should work yes. Fedora by default disables hardware accelerated video encoding but if you use flatpak versions of software (in this case the flatpak version of gpu screen recorder) then it should work. Even 12 year old gpus work.

Lower framerate doesn't really decrease video size because of how videos work, but you can set bitrate quality for the recorded video to reduce the video quality a bit to decrease the size.

dwoldrich•1mo ago
Was considering building a streaming rig around a Mac Mini. I wonder if with these performance enhancements, that will work for me?
keyle•1mo ago
Highly depends on what you're streaming. If you stream arcade 2D games of the past, or software development, it should be perfectly fine.

AAA titles with newer graphics, well, you can always send a capture the PC with the nvidia card's screen through a capture card.

Back in my days of streaming, macOS was no option, cca. 2017. Today I'd do it with any M processor mac without a second thought.

KronisLV•1mo ago
I actually used an M1 MacBook Air for encoding/compositing by sending the video/audio sources over from my main PC with DistroAV (LAN).

Worked reasonably well (you can send camera/VTuber output and captured video from game and any overlays separately, or just use the setup in a similar way to a capture card and run ONLY the game on the gaming PC and everything else on the Mac), but added some complexity to it all.

A beefy Nvidia GPU would make that setup not necessary, unless you want to directly play games on the Mac.

stephen_g•1mo ago
Streaming video from camera? In general the newer Mac Minis in general were fine already just because the M-series chips are very fast, but hopefully this should make it much more efficient
dwoldrich•1mo ago
That's great to hear, but perhaps I will ask too much even of the M-series chips.

Occasionally, I will show 3 things at once: an MP4 that the Mac Mini plays from its storage transitioning into captured hdmi signal from a canon camera as picture-in-picture with the main body of the stream containing captured hdmi output from my development laptop.

I'm not sure what my capture solution will be, but it seems there are a wide variety of USB-C capture adapters that I could use that are compatible with OBS on Mac and are even bus powered.

Other comments seem to indicate there are bugs in that specific picture-in-picture setup, but I'm sure those will get ironed out.

Venn1•1mo ago
I’m more excited about the upcoming support for VST3, but this is still welcome news. It is far easier than getting hardware encoding working with Rockchip SoCs on Linux.
JSR_FDED•1mo ago
The submitted title buries the lede. It should be:

“OBS Studio Gets A New Renderer: How OBS Adopted Metal”

RobotToaster•1mo ago
Also Mac only, since non Mac users won't have a clue what metal means in this context.
smcnally•1mo ago
“Mac-only” was disappointing to read, but OBS’ render performance has been fine on macos and linux even with older hardware. James Webb calls anything heavier than helium “metal.”
MBCook•1mo ago
Well Metal is the limitation there.

But they’ve clearly learned a lot that will help in the future with other modern APIs like DX12 or Vulcan.

monster_truck•1mo ago
It actually wasn't, though.

That's besides the point though, the OS has been trash for realtime encoding for over a decade now. At the very least you have to write a script to repeatedly renice the process back to the top when it tries to protect you from the excessive thermal load lmao

mariusmg•1mo ago
>James Webb calls anything heavier than helium “metal.”

And i call it great music.

zdw•1mo ago
I wonder how this improves performance on older Intel macs with a Metal-compatible GPUs, or if it's really a M-series only improvement.
stephen_g•1mo ago
It says in passing As the Metal backend is only supported on Apple Silicon devices, GPU and CPU share the same memory in the part talking about the differences between the Direct3D and Metal render pipelines.

Not sure why though, because Metal 3 is still supported on a bunch of Intel Macs...

daviddever23box•1mo ago
It may be an error on the part of the writer.
zdw•1mo ago
Maybe the M-series unified memory architecture is required?
andrekandre•1mo ago

  > Metal takes Direct3D's object-oriented approach one step further by combining it with the more "verbal" API design common in Objective-C and Swift in an attempt to provide a more intuitive and easier API for app developers to use (and not just game developers) and to further motivate those to integrate more 3D and general GPU functionality into their apps. 
slightly off-topic perhaps, but i find it amazing that an os-level 3d graphics api can be built in such a dynamic language as objective-c; i think it really goes to show how much optimization put in `objc_msgSend()`... it does a lot of heavy lifting in the whole os.
Rohansi•1mo ago
Modern graphics APIs minimize the number of graphics API calls vs. OpenGL and similar. Vulkan/Metal/DirectX 12 will have you pass command buffers with many commands in them instead of separate API calls for everything.
pmalynin•1mo ago
Yes and https://reviews.llvm.org/D69991
adamnemecek•1mo ago
There is a Metal Obj-C API, Metal implementation is C++.
almostgotcaught•1mo ago
No it's not - the compiler for MSL is of course C++ because it's LLVM but the runtime is absolutely written in objc (there weren't even C++ bindings until recently).
adamnemecek•1mo ago
No, I mean what is inside the Objective-C objects. Essentially everything on macOS has an Objective-C API but is implemented using C++. Have you ever noticed the ".cxx_destruct" method on like all objects?

What you are talking about are C++ wrappers around Metal Objective-C API. Yes, it is weird as they are going C++ -> Objective-C -> C++. Why not go directly? Because Apple does not ship C++ systems frameworks.

The term is Objective-C++.

jasonwatkinspdx•1mo ago
It's been possible for quite some time.

In the early 2000's there was a book on using Direct3D from C# that was pretty influential as far as changing people's assumption that you couldn't do high performance graphics in a GC'd language. In the end a lot of the ideas overlap with what c/c++ gamedevs do, like structuring everything around fixed sized tables allocated at load time and then minimal dynamic memory usage within the frame loop. The same concepts can apply at the graphics API level. Minimize any dynamic language overhead by dispatching work in batches that reference preallocated buffers. That gets the language runtime largely out of the way.

monster_truck•1mo ago
No, it doesn't. You won't find it used much if at all at these levels of the OS. Once you get past cocoa and friends it's restricted subsets of C++ (IOKit for example)
pjmlp•1mo ago
Yes it does, see NeXTSTEP, even the drivers were written in Objective-C.
maxlin•1mo ago
Hope they'll fix the obvious bugs like CPU use going to 60% doing nothing after restore from hibernation next
daviddever23box•1mo ago
It's never "doing nothing" - you just need more visibility into your running tasks.

Turning off nearly everything iCloud- or Spotlight-related is a pretty good start; disable network access and you may find even more pearls of wisdom.

MBCook•1mo ago
Great article. The description of how they handle shaders is just bonkers to me.

Is that really what you’d have to go through to have a working system with plugin shaders from 3rd parties on multiple backends? Or is mostly the result of time and trying to keep backwards compatibility with existing plugins?

Telling external devs “Write a copy in every shader language” would certainly be easier for the core team but that’s obviously undesirable.

delusional•1mo ago
Transpiling shaders is what most game engines have done for a decade now. Everybody thinks it's stupid in that field as well, but there is no viable alternative.
ZiiS•1mo ago
I think it was the most game engines once they adopted Direct 3D 8; so over two decades now.
hnuser123456•1mo ago
MS/NV are trying to start a program to pre-compile shaders for common hardware configurations and games/engines, and simply download them to clients.

https://devblogs.microsoft.com/directx/introducing-advanced-...

Cieric•1mo ago
I think you mean MS/AMD since this is for hardware with AMD parts in it.
hnuser123456•1mo ago
Fair point.
leecommamichael•1mo ago
I hope Modern GPU APIs are just a stepping stone to something simpler. OpenGL is loved and hated; and I have grown to love it after using the new stuff.
caseyf7•1mo ago
Apple should dedicate some resources to making this successful. Metal could use more wins outside of Apple itself.
vegabook•1mo ago
see Blender
ayi•1mo ago
I'm no expert on topic. So, I maybe understood only 5% of what I read but I wish we had more posts like that. Announcements without any technical details sounds like marketing pieces.
aizk•1mo ago
Same. I'm a python/typescript guy, so many details flew over my head, but I knew HN would like it.
zeeeeeebo•1mo ago
now all macOS streamers need is games!
jdboyd•1mo ago
Not all streamers are game streamers, and not all obs users are streamers. I installed on all of my workstations for its screen capture and virtual camera features.
robert_foss•1mo ago
This quite clearly shows the cost of Apple preferring to build a software ecosystem moat, than using the Vulkan API which every other OS supports.

Vulkan support was introduced in OBS Studio 25.0 in March 2020, 5.5 years ago.

jdboyd•1mo ago
Metal does pre date Vulkan, and some people consider it easier to use.
badsectoracula•1mo ago
While Metal might be easier to use, i'm pretty sure it is still easier to have to worry about Vulkan alone than Vulkan+Metal. And Metal predating Vulkan is really only of concern to code that existed before Vulkan was made available (which wasn't that much).
brnt•1mo ago
Mantle predates either, and Vulkan is based on Mantle.
JimmaDaRustla•1mo ago
Well, ya, it's a proprietary walled garden solution.
array_key_first•1mo ago
OpenGL is easier to use than both, but we left it in the dust as it doesn't match the semantics of modern hardware.

Metal DOES... but only apple hardware.

stephen_g•1mo ago
As if nobody else ever did that (like Microsoft with DirectX, and almost every single games console)?
robert_foss•1mo ago
Sure, it's happened before but it is not in Apples customers interests, just Apples corporate moat building interests.
pjmlp•1mo ago
Vulkan is not supported on game consoles, with the exception of Switch, and even there you should use NVN instead.

It is not officially supported on Windows, it works because the GPU vendors use the Installable Client Driver API, to bring their own driver stack. This was initially created for OpenGL, and nowadays sits on top of the DirectX runtime.

On the embedded space, the OSes that support graphical output many are stil focused on OpenGL ES.

nuudlman•1mo ago
Vulkan capture support on Windows was introduced in v25 (on linux you need to use a plugin). There is no Vulkan renderer support—which the post clearly stated...
rieter•1mo ago
OBS has no Vulkan renderer. Only OpenGL, DirectX 11 (on Windows), and now Metal.
